Dark circles indicate regions in space where the cosmic microwave background has temperature variations that are lower than average. The features hint that the universe was born long before the Big Bang 13.7 billion years ago and had undergone myriad cycles of birth and death before that time. See: Cosmic rebirth

Concentric circles in WMAP data may provide evidence of violent pre-Big-Bang activity

Authors: V.G.Gurzadyan, R.Penrose

(Submitted on 16 Nov 2010)

Abstract: Conformal cyclic cosmology (CCC) posits the existence of an aeon preceding our Big Bang 'B', whose conformal infinity 'I' is identified, conformally, with 'B', now regarded as a spacelike 3-surface. Black-hole encounters, within bound galactic clusters in that previous aeon, would have the observable effect, in our CMB sky, of families of concentric circles over which the temperature variance is anomalously low, the centre of each such family representing the point of 'I' at which the cluster converges. These centres appear as fairly randomly distributed fixed points in our CMB sky. The analysis of Wilkinson Microwave Background Probe's (WMAP) cosmic microwave background 7-year maps does indeed reveal such concentric circles, of up to 6{\sigma} significance. This is confirmed when the same analysis is applied to BOOMERanG98 data, eliminating the possibility of an instrumental cause for the effects. These observational predictions of CCC would not be easily explained within standard inflationary cosmology.

More on the low variance circles in CMB sky

Authors: V.G.Gurzadyan, R.Penrose

(Submitted on 7 Dec 2010)

Abstract: Two groups [3,4] have confirmed the results of our paper concerning the actual existence of low variance circles in the cosmic microwave background (CMB) sky. They also point out that the effect does not contradict the LCDM model - a matter which is not in dispute. We point out two discrepancies between their treatment and ours, however, one technical, the other having to do with the very understanding of what constitutes a Gaussian random signal. Both groups simulate maps using the CMB power spectrum for LCDM, while we simulate a pure Gaussian sky plus the WMAP's noise, which points out the contradiction with a common statement [3] that "CMB signal is random noise of Gaussian nature". For as it was shown in [5], the random component is a minor one in the CMB signal, namely, about 0.2. Accordingly, the circles we saw are a real structure of the CMB sky and they are not of a random Gaussian nature. Although the structures studied certainly cannot contradict the power spectrum, which is well fitted by LCDM model, we particularly emphasize that the low variance circles occur in concentric families, and this key fact cannot be explained as a purely random effect. It is, however a clear prediction of conformal cyclic cosmology.

Holometer

Holometer Revised

This plot shows the sensitivity of various experiments to fluctuations in space and time. Horizontal axis is the log of apparatus size (or duration time the speed of light), in meters; vertical axis is the log of the rms fluctuation amplitude in the same units. The lower left corner represents the Planck length or time. In these units, the size of the observable universe is about 26. Various physical systems and experiments are plotted. The "holographic noise" line represents the rms transverse holographic fluctuation amplitude on a given scale. The most sensitive experiments are Michelson interferometers.

The Fermilab Holometer in Illinois is currently under construction and will be the world's most sensitive laser interferometer when complete, surpassing the sensitivity of the GEO600 and LIGO systems, and theoretically able to detect holographic fluctuations in spacetime.^[1][2][3]

The Holometer may be capable of meeting or exceeding the sensitivity required to detect the smallest units in the universe called Planck units.^[1] Fermilab states, "Everyone is familiar these days with the blurry and pixelated images, or noisy sound transmission, associated with poor internet bandwidth. The Holometer seeks to detect the equivalent blurriness or noise in reality itself, associated with the ultimate frequency limit imposed by nature."^[2]
Craig Hogan, a particle astrophysicist at Fermilab, states about the experiment, "What we’re looking for is when the lasers lose step with each other. We’re trying to detect the smallest unit in the universe. This is really great fun, a sort of old-fashioned physics experiment where you don’t know what the result will be."

Experimental physicist Hartmut Grote of the Max Planck Institute in Germany, states that although he is skeptical that the apparatus will successfully detect the holographic fluctuations, if the experiment is successful "it would be a very strong impact to one of the most open questions in fundamental physics. It would be the first proof that space-time, the fabric of the universe, is quantized."^[1]

Fermilab Holometer

About a hundred years ago, the German physicist Max Planck introduced the idea of a fundamental, natural length or time, derived from fundamental constants. We now call these the Planck length, lp = √hG/2π c3 = 1.6 × 10-35 meters. Light travels one Planck length in the Planck time, tp = √hG/2π c⁵ = 5.4 × 10^-44seconds. 

The physics of space and time is expected to change radically on such small scales. For example, a particle confined to a Planck volume automatically collapses to a black hole.

A Conceptual Drawing of the 'Holometer' via Symmetry

“The shaking of spacetime occurs at a million times per second, a thousand times what your ear can hear,” said Fermilab experimental physicist Aaron Chou, whose lab is developing prototypes for the holometer. “Matter doesn’t like to shake at that speed. You could listen to gravitational frequencies with headphones.”

The whole trick, Chou says, is to prove that the vibrations don’t come from the instrument. Using technology similar to that in noise-cancelling headphones, sensors outside the instrument detect vibrations and shake the mirror at the same frequency to cancel them. Any remaining shakiness at high frequency, the researchers propose, will be evidence of blurriness in spacetime

“With the holometer’s long arms, we’re magnifying spacetime’s uncertainty,” Chou said.

Quantum suicide and immortality

But for the first time, quantum physicist Seth Lloyd of the Massachusetts Institute of Technology suggests that memories of entanglement can survive its destruction. He compares the effect to Emily Brontë’s novel Wuthering Heights: “the spectral Catherine communicates with her quantum Heathcliff as a flash of light from beyond the grave.”Where Susskind leaves off, Seth Lloyd begins

In Max' Tegmark's assessment of Quantum Immortality, "Although quantum immortality is motivated by the quantum suicide thought experiment, Max Tegmark has stated that he does not believe that quantum immortality is a consequence of his work,"I thought to trace some perspective about what happened with the thought experiment of Susskind's versus the telling tale of what happens inside the blackhole based on the idea of something that is left outside the blackhole for consideration.

The consequence of sound in analogy serves to help us not only orientate causal action from direct contact, but the realization that such contact has consequences. It is befitting such thought experiments or analogies can help push the mind toward accepting the world in a different light so it understands that there is more to the world in which we see as observers, but also of what we meet through such contact as a manifestation through experiences.

Savas Dimopoulos

Here’s an analogy to understand this: imagine that our universe is a two-dimensional pool table, which you look down on from the third spatial dimension. When the billiard balls collide on the table, they scatter into new trajectories across the surface. But we also hear the click of sound as they impact: that’s collision energy being radiated into a third dimension above and beyond the surface. In this picture, the billiard balls are like protons and neutrons, and the sound wave behaves like the graviton.See Also: The Sound Of Billiard Balls

How Quantum Suicide Works

by Josh Clark

***

In quantum mechanics, quantum suicide is a thought experiment. It was originally published independently by Hans Moravec in 1987 and Bruno Marchal in 1988 and was further developed by Max Tegmark in 1998.^[1] It attempts to distinguish between the Copenhagen interpretation of quantum mechanics and the Everett many-worlds interpretation by means of a variation of the Schrödinger's cat thought experiment. The experiment involves looking at the Schrödinger's cat experiment from the point of view of the cat.

Quantum immortality is a metaphysical speculation derived from the quantum suicide thought experiment. It states that the many-worlds interpretation of quantum mechanics implies that conscious beings are immortal.^[2] Hugh Everett is reported to have believed in quantum immortality, although he never published on either quantum suicide or quantum immortality.^[3]

The quantum suicide thought experiment

Unlike Schrödinger's cat-in-a-box thought experiment which used poison gas and a radioactive decay trigger, this human version involves some sort of lethal weapon and a machine which measures the spin value of a photon. Every 10 seconds, the spin value of a randomly passing photon is measured. Depending on the orientation of the spin, either the weapon is deployed and the man is killed, or it is not and he lives.

With each run of the experiment there is a 50-50 chance that the weapon will be triggered and the experimenter will die. According to the Copenhagen interpretation, the weapon will (in all likelihood) eventually be triggered and the experimenter will die. If the many-worlds interpretation is correct then at each run of the experiment, the experimenter will be split into several worlds in which he dies and a few worlds in which he survives. In the worlds where the experimenter dies, he will cease to be a conscious entity.

However, from the point of view of the non-dead copies of the experimenter, the experiment will continue running without his ceasing to exist, because at each branch, he will only be able to observe the result in the world in which he survives, and if many-worlds is correct, the surviving copies of the experimenter will notice that he never seems to die, therefore "proving" himself to be invulnerable to the killing mechanism in question, from his own point of view.

If the many-worlds interpretation is true, the measure (given in the many-worlds interpretation by the squared norm of the wavefunction) of the surviving copies of the experimenter will decrease by 50% with each run of the experiment, but will remain non-zero. So, if the surviving copies become experimenters, those copies will either die during their first attempt, or survive creating duplicates of themselves (copies of copies, that will survive finitely or die).

 Quantum immortality

The idea behind quantum immortality is that, in running the quantum thought experiment, the experimenter may remain alive and, thus, be able to experience at least one of the universes in this set (even though these universes form a tiny subset of all possible universes). Over time, the experimenter would therefore never perceive his or her own death.

Surviving the quantum thought experiment

The small-probability remaining branches are in effect, though unlikely to be experienced by most of the copies of the experimenter that started out. Most of the observer-moments in the universe will not be in such low-measure situations because measure is proportional to the number of copies and therefore the number of that type of observer-moment.

However, the rareness of an observer moment has no relation to presence or absence of experience; if the many-worlds interpretation is true, all non-zero observer moments are experienced, even rare ones. Believers in quantum suicide think it gives a recipe for entering into rare observer moments. The experimenter indeed knows that this type of observer moment is rare, which is why it would be unlikely to occur in interpretations of quantum physics that don't have many worlds.

In the branching worlds, the observer has one of two possibilities, live or die. If he is alive, then presumably he does not recall the death. In the other reality, he is dead (and ceases to exist in that reality). If the experiment is repeated over and over, there will always be a reality where the observer never dies. This reality will finally convince the observer that it is impossible to die.

Required assumptions

Proponents of the quantum immortality point out that, although it is highly speculative, the theory does not violate any known laws of physics—but only if certain controversial assumptions are made:

1. That the many-worlds interpretation is the correct interpretation of quantum mechanics, as opposed to the Copenhagen interpretation, the latter of which does not involve the existence of parallel universes. Note, though, that parallel universes may be possible through other mechanisms in the Copenhagen interpretation.
2. Not dying some finite number of times (perhaps in parallel universes) constitutes immortality.
3. Permanent cessation of the consciousness, along with the ability to observe, occurs at physical destruction (death).

Arguments against quantum immortality

David Papineau argues against the quantum suicide argument thus: "If one outcome is valuable because it contains my future experiences, surely an alternative outcome which lacks those experiences is of lesser value, simply by comparison with the first outcome. Since expected utility calculations hinge on relative utility values rather than absolute ones, I should be concerned about death as long as the outcome where I die is given less utility than the one where I survive, whatever the absolute value."^[4]

Jacques Mallah expands on this "utility" argument,^[5] suggesting that quantum suicide cannot give a recipe for "entering into" rare or "low measure" observer moments. This is because the amount of consciousness or "measure" of these rare observer moments is exactly as much as it would have been without the quantum suicide; in that case quantum suicide merely removes the other observer-moments. This is equivalent, in Mallah's view, to a single-world situation in which one starts off with many copies of the experimenter, and the number of surviving copies is decreased by 50% with each run. Therefore, according to this argument, the quantum nature of the experiment provides no benefit to the experimenter; in terms of his/her subjective life expectancy or rational decision making, or even in terms of his/her trying to decide whether the many-worlds interpretation is correct, the many-worlds interpretation gives results that are the same as that of a single-world interpretation.^[5]
Mallah also gives a "general argument against immortality" which argues that if people are immortal, then it is vanishingly unlikely to find oneself to be of a normal age rather than abnormally old.

It has been countered that in a many-worlds interpretation, the amplitude of being the living experimenter can be halved repeatedly without ever reaching zero. However, this point is not disputed by opponents of quantum suicide; rather, they claim that it is not the issue, while Mallah claims that the decrease in measure is the issue.

Max Tegmark's work

Using logic similar to that of Greg Egan's Dust Theory, Max Tegmark argues that under any sort of normal conditions, before someone dies they undergo a period of diminishment of consciousness, a non-quantum decline (which can be anywhere from seconds to minutes to years), and hence there is no way of establishing a continuous existence in this world to an alternate one in which the person ceases to exist.^[6] Although quantum immortality is motivated by the quantum suicide thought experiment, Max Tegmark has stated that he does not believe that quantum immortality is a consequence of his work^.

David Lewis's work

The philosopher David Lewis, in "How Many Lives Has Schrödinger's Cat?", remarked that in the vast majority of the worlds in which an immortal observer might find himself (i.e. the subset of quantum-possible worlds in which the observer does not die), he will survive, but will be terribly maimed. This is because in each of the scenarios typically given in thought experiments (nuclear bombing, Russian roulette, etc.), for every world in which the observer survives unscathed, there are likely to be far more worlds in which the observer survives terribly disfigured, badly disabled, and so on. It is for this reason, Lewis concludes, that we ought to hope that the many-worlds interpretation is false.^[7]

Derek Parfit's work

In Reasons and Persons Derek Parfit used thought experiments ranging from teleportation to gradual changes to your psychology to argue that personal identity isn't a deep fact about the world. After quantum suicide there would be worlds with persons that shared your memories and there would be worlds without such persons. There is no Cartesian ego which does or doesn't survive.

Other criticism and controversy

Critics^[who?] contend quantum suicide fails as a thought experiment to achieve its intended purpose. Nonetheless, there are arguments^[specify] involving anthropic considerations among entire universes which do provide evidence^[specify] for the many-worlds interpretation.^[8]
Quantum suicide and quantum immortality remain controversial because a number of thinkers^[who?] disagree on its success or failure and, particularly, its relevance to life expectancy and decision making.

In fiction

Main article: Quantum suicide and quantum immortality in fiction

Authors^[who?] of science fiction have used themes involving both quantum suicide and quantum immortality. The idea that authors exploit is that a person who dies in one world may survive in another world or parallel universe.

Quantum suicide

Quantum suicide themes have been explored in the following works:

• Larry Niven's short story "All the Myriad Ways", collected in a collection of the same name (1971)
• Dan Simmons's novel The Hollow Man (1992). Simmons also describes a quantum execution mechanism in his Hyperion Cantos series.
• Greg Egan's novel Quarantine (1992)
• Greg Egan's novel Permutation City (1994), in which one character repeatedly had his mind uploaded and his copy eventually terminated, but found out that he always "ended up" in another world, where his survival was explained by increasingly improbable circumstances.
• Robert Charles Wilson's short story Divided by Infinity (1998)
• Denis Johnson's novel Already Dead (A California Gothic) (1998)
• Jason Shiga's book Meanwhile (2004)
• Greg Bear's short Story "Schrodinger's Plague" found in his book Tangents deals with a doomsday version of this experiment in which instead of a single scientist dying, a deadly virus is released into the populace.

Quantum immortality

Quantum immortality themes have been explored in several works:

Books

• The Greg Egan novel Quarantine explores topics related to quantum immortality.
• In the Greg Egan short story The Infinite Assassin, the title character explicitly defines himself this way: "'I' am those who survive, and succeed. The rest are someone else."
• Other science fiction stories exploring these and related ideas include All the Myriad Ways by Larry Niven, and Divided by Infinity by Robert Charles Wilson.
• Terry Pratchett's short story Death and What Comes Next has a philosopher arguing the principle with Death, who has come for him.
• Steven Hall's novel The Raw Shark Texts contains references to Max Tegmark and the Quantum Machine Gun (an alternate name for the quantum suicide thought experiment) suggesting a possible quantum immortality -related reading of the story.
• In Neal Stephenson's 2008 novel Anathem, the concept of quantum immortality factors significantly, if under different names.

Intelligent Life in the Universe?

While Drake's equation is a good basis for systematic investigations of signals from extraterrestrial intelligences, I care little about the admittedly scarce possibility that we ever receive positive news from our SETI searches. I care more about the fact that, if we consider the whole universe instead than restricting to our small galaxy, and if we omit to require that other civilizations exist at present (whatever this means over billion-light-year distance scales), the probability becomes a certainty.Tommaso Dorigo

I was over at Tommaso Dorigo's Blog, Quantum Diaries Survivor" reading his take on Extraterrestrials: A Dime A Dozen and the opening with Stephen Hawkings Lecture. I cut out the section of my interest as well to see what Dr. Hawking was talking about, besides reading Tommaso's take.

Qualitatively, I have come to realize,  given the framework for consideration of such possibilities,  these equations mean an inductive/deductive self evident constraint  how are we ever to consider the possibility( You have to give yourself permission to entertain).

I mean can we ever know the framework of that Extraterrestrial Intelligence given the parameters for our own belief structures? We do not even know what is possible "not having the framework" to properly question how this can be so?

So what I found in Dr.Hawkings lecture was the generalities of consensus across the industry of science and no new ways in which to possibly perceive the" right questions concerning the framework for possible new intelligences" that we would perceive as Extraterrestrials.

NASA's 50th Anniversary Lecture By Professor Stephen Hawking

...........DR. HAWKING: What will we find when we go into space? Is there alien life out there, or are we alone in the universe?

We believe that life arose spontaneously on the Earth. So it must be possible for life to appear on othersuitable planets, of which there seem to be a large number in the galaxy.

But we don't know how life first appeared. The probability of something as complicated as a DNA molecule being formed by random collisions of atoms in ocean is incredibly small. However, there might have been some simpler macro molecule which can build up the DNA or some other macro molecule capable of reproducing itself. Still, even if the probability of life appearing on a suitable planet is very small, since the universe is infinite, life would have appeared somewhere. If the probability is very low, the distance between two independent occurrences of life would be very large.

However, there is a possibility known as panspermia that life could spread from planet to planet or from stellar system to stellar system carried on meteors. We know that Earth has been hit by meteors that came from Mars, and others may have come from further afield. We have no evidence that any meteors carried life, but it remains a possibility.

An important feature of life spread by panspermia is that it would have the same basis which would be DNA for life in the neighborhood of the Earth.

On the other hand, an independent occurrence of life would be extremely unlikely to be DNA based. So watch out if you meet an alien. You could be infected with a disease against which you have no resistance.

One piece of observational evidence on the probability of life appearing is that we have fossils from 3.5 billion years ago. The Earth was formed 4.6 billion years ago and was probably too hot for about the first half billion years. So life appeared on Earth within half-a-billion years of it being possible, which is short compared to the 10-billion-year lifetime of an Earth-like planet.

This would suggest either panspermia or that the probability of life appearing independently is reasonably high. If it was very low, one would have expected it to take most of the 10 billion years available. If it is panspermia, any life in the solar system or in nearby stellar systems will also be DNA based.

While there may be primitive life in another region of the galaxy, there don't seem to be any advanced intelligent beings. We don't appear to have been visited by aliens. I am discounting reports of UFOs. Why would they appear only to cranks and weirdos?

[Laughter.]

DR. HAWKING: If there is a government conspiracy to suppress the reports and keep for itself the scientific knowledge the aliens bring, it seems to have been a singularly ineffective policy so far.

Furthermore, despite an extensive search by the SETI project, we haven't heard any alien television quiz shows. This probably indicates that there are no alien civilizations at our stage of development within the radius of a few hundred lightyears. Issuing an insurance policy against abduction by aliens seems a pretty safe bet.

Why haven't we heard from anyone out there? One view is expressed in this Calvin cartoon. The caption reads: "Sometimes I think that the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us."

More seriously, there could be three possible explanations of why we haven't heard from aliens. First, it may be that the probability of primitive life appearing on a suitable planet is very low.

Second, the probability of primitive life appearing may be reasonably high, but the probability of that life developing intelligence like ours may be very low. Just because evolution led to intelligence in our case, we shouldn't assume that intelligence is an inevitable consequence of Darwinian natural selection.

It is not clear that intelligence confers a long-term survival advantage. Bacteria and insects will survive quite happily even if our so-called intelligence leads us to destroy ourselves.

This is the third possibility. Life appears and in some cases develops into intelligent beings, but when it reaches a stage of sending radio signals, it will also have the technology to make nuclear bombs and other weapons of mass destruction. It will, therefore, be in danger of destroying itself before long.

Let's hope this is not the reason we have not heard from anyone. Personally, I favor the second possibility that primitive life is relatively common, but that intelligent life is very rare. Some would say it has yet to occur on Earth.

[Laughter.]

DR. HAWKING: Can we exist for a long time away from the Earth? Our experience with the ISS, the International Space Station, shows that it is possible for human beings to survive for many months away from Planet Earth. However, the zero gravity aboard it causes a number of undesirable physiological changes and weakening of the bones, as well as creating practical problems with liquids, et cetera.

One would, therefore, want any long-term base for human beings to be on a planet or moon. By digging into the surface, one would get thermal insulation and protection from meteors and cosmic rays. The planet or moon could also serve as a source of the raw materials that would be needed if the extraterrestrial community was to be self-sustaining independently of Earth.

What are the possible sites of a human colony in the solar system? The most obvious is the Moon. It is close by and relatively easy to reach. We have already landed on it and driven across it in a buggy.

On the other hand, the Moon is small and without atmosphere or a magnetic field to deflect the solar radiation particles, like on Earth. There is no liquid water, but there may be ice in the craters at the north and south poles. A colony on the Moon could use this as a source of oxygen with power provided by nuclear energy or solar panels. The Moon could be a base for travel to the rest of the solar system.

Mars is the obvious next target. It is half as far, again, as the Earth from the Sun and so receives half the warmth. It once had a magnetic field, but it decayed 4 billion years ago, leaving Mars without protection from solar radiation. It stripped Mars of most of its atmosphere, leaving it with only 1 percent of the pressure of the Earth's atmosphere.

However, the pressure must have been higher in the past because we see what appear to be runoff channels and dried-up lakes. Liquid water cannot exist on Mars now.

It would vaporize in the near-vacuum. This suggests that Mars had a warm wet period during which life might have appeared either spontaneously or through panspermia. There is no sign of life on Mars now, but if we found evidence that life had once existed, it would indicate that the probability of life developing on a suitable planet was fairly high.

NASA has sent a large number of spacecraft to Mars, starting with Mariner 4 in 1964. It has surveyed the planet with a number of orbiters, the latest being the Mars Reconnaissance Orbiter. These orbiters have revealed deep gullies and the highest mountains in the solar system.

NASA has also landed a number of probes on the surface of Mars, most recently the two Mars Rovers. These have sent back pictures of a dry desert landscape. However, there is a large quantity of water in the form of ice in the polar regions. A colony on Mars could use this as a source of oxygen.

There has been volcanic activity on Mars. This would have brought minerals and metals to the surface which a colony could use.

The Moon and Mars are the most suitable sites for space colonies in the solar system. Mercury and Venus are too hot, while Jupiter and Saturn are gas giants with no solid surface.

The moons of Mars are very small and have no advantages over Mars itself.

Some of the moons of Jupiter and Saturn might be possible. In particular, Titan, a moon of Saturn, is larger and more massive than other moons and has a dense atmosphere.

The Cassini-Huygens Mission of NASA and ESA has landed a probe on Titan which has sent back pictures of the surface. However, it is very cold, being so far from the sun, and I wouldn't fancy living next to a lake of liquid methane.

What about beyond the solar system? Our observations indicate that a significant fraction of stars have planets around them. So far, we can detect only giant planets like Jupiter and Saturn, but it is reasonable to assume that they will be accompanied by smaller Earth-like planets. Some of these will lay in the [inaudible] zone where the distance from the stars is the right range for liquid water to exist on their surface.

There are around a thousand stars within 30 lightyears of Earth. If 1 percent of each had Earth-size planets in the [inaudible] zone, we would have 10 candidate new worlds. We can revisit it with current technology, but we should make interstellar a long-term aim. By long term, I mean over the next 200 to 500 years. The human race has existed as a separate species for about 2 million years.

Civilization began about 10,000 years ago, and the rate of development has been steadily increasing.

If the human race is to continue for another million years, we will have to boldly go where no one has gone before.

***

This same perspective about which I have involved myself with the issues of gravity has been at the forefront of my journey with regards to understanding gravity, and what we have come to know of it on Earth, is that it is not as it is in heaven?:)

Thoughts have this forming effect too, and in the world of Physical constants, how are such thoughts to be measured? "Particulate expressions" in such reductionist modes which lead to a inductive/deductive self evidential state of a ever forming Higg's field?? What thought has traversed the room, to arrive on the other side of the room with consensus?

Not as if, we can defy it's hold on us, while taking plane flights to experience this sensation of dropping fast to earth and leaving ourselves suspended for a time. That it is a consensus borne in mind that such an idea is limited to the framework for which all ideas about it are limited too.

The net result is that the meager N=2.1 becomes over 20 trillions! This means that there are presently 20 trillion civilizations around. 20 trillions. Okay, we might have dropped or added one factor of a hundred too many here or there, but the number is still enormous, no escape!

Is that not a sobering thought ? To me, that is both awesome and saddening. As far as awe is concerned, of course there is no need to explain it. But there is sadness too: for imagine the incredible, unfathomable number of things that we will never be able to know, constrained in our tiny planet, during our insignificant lives. Masterpieces, inventions, acts of bravery, adventures. But also wars, atrocities, catastrophes. The history of the universe will never be written - but it would be quite a read, I am sure.Tommaso Dorigo

So as with the idea of Intelligences in the universe, I place gravity along side of it, as in the context of formulating the right questions. In Tommaso's blog the entry is the deciphering in context of the Drake Equation yet not bound by it in belief. This does not make Tommaso irresponsible to me in shirking the basis of that determination by using the equation.

So of course along the way in my endeavors with those who I have conversed, or left trail bytes for consideration, is the idea that the world as we see it is not always as it seems and that by consensus, the framework is establish is one which limits our views according too.

A "synopsis of the events" can lead us too, and as has been extrapolated according to the world of science. The thoughts that are left to me have been the idea of how scientists can ever introduce new formulations outside of that structure consensus without first taking a new baby step(how so?). They have had to all come to agreement on the latest version of that consensus.

Then there are, the Physical Constants. It is as if in relation to the formulation to a mathematical consistency as a correlative function of the Drake equation in the process of.

This does not mean we sanction irresponsibility to the quest of discovering new worlds of thought, be it in context of Extraterrestrial Intelligences, or even about gravity and the quantum world in which it shall work.

I still visit those scientists who have placed "Outreach" even amidst the data and scientific endeavors they are pursuing. I look for the glimmer of hope that such baby steps are borne out of such minds.

Having defined all the parameters of your science what would be the next question that would lead you to new insights? What new science beyond the experiments that you are working on?

About Complexity

Robert Betts Laughlin (born November 1, 1950) is a professor of Physics and Applied Physics at Stanford University who, together with Horst L. Störmer and Daniel C. Tsui, was awarded the 1998 Nobel Prize in physics for his explanation of the fractional quantum Hall effect.

Laughlin was born in Visalia, California. He earned a B.A. in Physics from UC Berkeley in 1972, and his Ph.D. in physics in 1979 at MIT, Cambridge, Massachusetts, USA. In the period of 2004-2006 he served as the president of KAIST in Daejeon, South Korea.

Laughlin shares similar views to George Chapline on the existence of black holes. See: Robert B. Laughlin

The Emergent Age, by Robert Laughlin

The natural world is regulated both by fundamental laws and by powerful principles of organization that flow out of them which are also transcendent, in that they would continue to hold even if the fundamentals were changed slightly. This is, of course, an ancient idea, but one that has now been experimentally demonstrated by the stupendously accurate reproducibility of certain measurements - in extreme cases parts in a trillion. This accuracy, which cannot be deduced from underlying microscopics, proves that matter acting collectively can generate physical law spontaneously.

Physicists have always argued about which kind of law is more important - fundamental or emergent - but they should stop. The evidence is mounting that ALL physical law is emergent, notably and especially behavior associated with the quantum mechanics of the vacuum. This observation has profound implications for those of us concerned about the future of science. We live not at the end of discovery but at the end of Reductionism, a time in which the false ideology of the human mastery of all things through microscopics is being swept away by events and reason. This is not to say that microscopic law is wrong or has no purpose, but only that it is rendered irrelevant in many circumstances by its children and its children's children, the higher organizational laws of the world.

In general usage, complexity tends to be used to characterize something with many parts in intricate arrangement. The study of these complex linkages is the main goal of network theory and network science. In science there are at this time a number of approaches to characterizing complexity, many of which are reflected in this article. Definitions are often tied to the concept of a ‘system’ – a set of parts or elements which have relationships among them differentiated from relationships with other elements outside the relational regime. Many definitions tend to postulate or assume that complexity expresses a condition of numerous elements in a system and numerous forms of relationships among the elements. At the same time, what is complex and what is simple is relative and changes with time.

Some definitions key on the question of the probability of encountering a given condition of a system once characteristics of the system are specified. Warren Weaver has posited that the complexity of a particular system is the degree of difficulty in predicting the properties of the system if the properties of the system’s parts are given. In Weaver's view, complexity comes in two forms: disorganized complexity, and organized complexity. ^[1] Weaver’s paper has influenced contemporary thinking about complexity. ^[2]

The approaches which embody concepts of systems, multiple elements, multiple relational regimes, and state spaces might be summarized as implying that complexity arises from the number of distinguishable relational regimes (and their associated state spaces) in a defined system.

Some definitions relate to the algorithmic basis for the expression of a complex phenomenon or model or mathematical expression, as is later set out herein.

Where Susskind leaves off, Seth Lloyd begins

A picture, a photograph, or a painting is not the real world that it depicts. It's flat, not full with three dimensional depth like the real thing. Look at it from the side-almost edge on. It doesn't look anything like the real scene view from a angle. In short it's two dimensional while the world is three dimensional. The artist, using perceptual sleight of hand, has conned you into producing a three dimensional image in your brain, but in fact the information just isn't there to form a three dimensional model of the scene. There is no way to tell if that figure is a distant giant or a close midget There is no way to tell if the figure is made of plaster or if it's filled with blood or guts. The brain is providing information that is not really present in the painted strokes on the canvas or the darken grains of silver on the photographic surface. The Cosmic Landscape by Leonard Susskind, page 337 and 338

 

See:The elephant and the event horizon 26 October 2006 by Amanda Gefter at New Scientist.

So while we design our methods of picturing how the universe looks, it is by design of the experimental procedures that we have pushed perspective toward the "depth of imaging"  that we design our views of what we propose is happening . So this then is a method based on the Gedankin that allows "an alternate view of the reality" of  what is happening inside the blackhole that was "thought of"  before we master  putting the perspective of what actually happens outside.

Gedanken Experiments Involving Black Holes

ABSTRACT

Analysis of several gedanken experiments indicates that black hole complementarity cannot be ruled out on the basis of known physical principles. Experiments designed by outside observers to disprove the existence of a quantum-mechanical stretched horizon require knowledge of Planck-scale effects for their analysis. Observers who fall through the event horizon after sampling the Hawking radiation cannot discover duplicate information inside the black hole before hitting the singularity. Experiments by outside observers to detect baryon number violation will yield significant effects well outside the stretched horizon.

 At 11:20 AM, September 13, 2009,  Bee said-The Schwarzschild radius depends on the mass, it thus doesn't define a fixed length. If one ties the Schwarzchild radius to the Compton wavelength via the uncertainty principle, one obtains a length and a mass, which is exactly the Planck length and Planck mass

While entertaining the issues put forward by "The Minimal Length in Quantum Gravity: An Outside View" some issues came to mind for pushing forward proposals that are current in science toward identification of how we can look at the inside of a blackhole with information postulated by illumination "outside."

Seth Lloyd is a professor of mechanical engineering at Massachusetts Institute of Technology. He refers to himself as a "quantum mechanic".

While one recognizes the relationship Susskind had pointed out by doing thought experiments in relation to what processes allow us to search "inside the blackhole" it is information that is "not lost"  that allows us to understand what is actually happening with time that moves within the blackhole's internal direction . This then is an "outside perspective" of what is held in contention to Planck's length that we might ask what the heck actually exist inside that we are all speculating about?

Quantum Entanglement Benefits Exist after Links Are Broken

By Charles Q. Choi

“Spooky action at a distance” is how Albert Einstein famously derided the concept of quantum entanglement—where objects can become linked and instantaneously influence one another regardless of distance. Now researchers suggest that this spooky action in a way might work even beyond the grave, with its effects felt after the link between objects is broken.

In experiments with quantum entanglement, which is an essential basis for quantum computing and cryptography, physicists rely on pairs of photons. Measuring one of an entangled pair immediately affects its counterpart, no matter how far apart they are theoretically. The current record distance is 144 kilometers, from La Palma to Tenerife in the Canary Islands.

In practice, entanglement is an extremely delicate condition. Background disturbances readily destroy the state—a bane for quantum computing in particular, because calculations are done only as long as the entanglement lasts. But for the first time, quantum physicist Seth Lloyd of the Massachusetts Institute of Technology suggests that memories of entanglement can survive its destruction. He compares the effect to Emily Brontë’s novel Wuthering Heights: “the spectral Catherine communicates with her quantum Heathcliff as a flash of light from beyond the grave.”

The insight came when Lloyd investigated what happened if entangled photons were used for illumination. One might suppose they could help take better pictures. For instance, flash photography shines light out and creates images from photons that are reflected back from the object to be imaged, but stray photons from other objects could get mistaken for the returning signals, fuzzing up snapshots. If the flash emitted entangled photons instead, it would presumably be easier to filter out noise signals by matching up returning photons to linked counterparts kept as references.

Still, given how fragile entanglement is, Lloyd did not expect quantum illumination to ever work. But “I was desperate,” he recalls, keen on winning funding from a Defense Advanced Research Projects Agency’s sensor program for imaging in noisy environments. Surprisingly, when Lloyd calculated how well quantum illumination might perform, it apparently not only worked, but “to gain the full enhancement of quantum illumination, all entanglement must be destroyed,” he explains.

Lloyd admits this finding is baffling—and not just to him. Prem Kumar, a quantum physicist at Northwestern University, was skeptical of any benefits from quantum illumination until he saw Lloyd’s math. “Everyone’s trying to get their heads around this. It’s posing more questions than answers,” Kumar states. “If entanglement does not survive, but you can seem to accrue benefits from it, it may now be up to theorists to see if entanglement is playing a role in these advantages or if there is some other factor involved.”

As a possible explanation, Lloyd suggests that although entanglement between the photons might technically be completely lost, some hint of it may remain intact after a measurement. “You can think of photons as a mixture of states. While most of these states are no longer entangled, one or a few remain entangled, and it is this little bit in the mixture that is responsible for this effect,” he remarks.

If quantum illumination works, Lloyd suggests it could boost the sensitivity of radar and x-ray systems as well as optical telecommunications and microscopy by a millionfold or more. It could also lead to stealthier military scanners because they could work even when using weaker signals, making them easier to conceal from adversaries. Lloyd and his colleagues detailed a proposal for practical implementation of quantum illumination in a paper submitted in 2008 to Physical Review Letters building off theoretical work presented in the September 12 Science.

Oh Dear!... How Technology has Changed Things

Mathematics, rightly viewed, possesses not only truth, but supreme beautya beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show. The true spirit of delight, the exaltation, the sense of being more than Man, which is the touchstone of the highest excellence, is to be found in mathematics as surely as in poetry.--BERTRAND RUSSELL, Study of Mathematics

The "Talking Pictures" Projection Wagon-

In the 1920's about the only entertainment that came to the rural community of Leakey, Texas was the traveling tent shows. This form of family entertainment would come to the canyon about once a year to the delight of all. Everyone looked forward to the horse drawn wagons that brought the much anticipated entertainment to town. In later years the horses were replaced by the Model T Fords but this form of transportation did not deter the excitement.

It is important sometimes to hone in on exactly what sets the mind to have it exemplify itself to a standard that bespeaks to the idealizations that can come forward from a most historical sense. It is in this way that while one can envision where the technological views have replaced the spoken word in movie pictures, we can see the theatre above as an emblazoned realization of what changes has been brought to society and what may have been lost in some peoples eyes.


This is a photograph of author and philosopher Robert M. Pirsigtaken by Ian Glendinning on the eve of the Liverpool conference of 7th July 2005.

What is in mind is a sort of Chautauqua...that's the only name I can think of for it...like the traveling tent-show Chautauquas that used to move across America, this America, the one that we are now in, an old-time series of popular talks intended to edify and entertain, improve the mind and bring culture and enlightenment to the ears and thoughts of the hearer. The Chautauquas were pushed aside by faster-paced radio, movies and TV, and it seems to me the change was not entirely an improvement. Perhaps because of these changes the stream of national consciousness moves faster now, and is broader, but it seems to run less deep. The old channels cannot contain it and in its search for new ones there seems to be growing havoc and destruction along its banks. In this Chautauqua I would like not to cut any new channels of consciousness but simply dig deeper into old ones that have become silted in with the debris of thoughts grown stale and platitudes too often repeated.

Zen and the Art of Motorcycle Maintenance Part 1 Chapter 1.(Bold added by me for emphasis)

I wanted to take the conversation and book presented by Phil and immortalize it in a way by laying it out for examination. Regardless of my opinions and viewpoint, the world goes on and the written work of Robert Pirsig persists as a "object of the material." In the beginning, no matter the choice to illuminate the ideal, it has been transgressed in a way by giving the symbols of language to a discerning mind and verily brought to that same material world for examination. How ever frustrating this may seem for Pirsig, it is a fact of light that any after word will reveal more then what was first understood. Reflection has this way about it in the historical revelation, of how the times are changing. Things dying and becoming new. The moon a reflection of the first light.

The conclusion of the whole matter is just this,—that until a man knows the truth, and the manner of adapting the truth to the natures of other men, he cannot be a good orator; also, that the living is better than the written word, and that the principles of justice and truth when delivered by word of mouth are the legitimate offspring of a man’s own bosom, and their lawful descendants take up their abode in others. Such an orator as he is who is possessed of them, you and I would fain become. And to all composers in the world, poets, orators, legislators, we hereby announce that if their compositions are based upon these principles, then they are not only poets, orators, legislators, but philosophers.

Plato, The Dialogues of Plato, vol. 1 [387 AD] PHAEDRUS.


***

IN announcing himself in the written work with regards to the IQ given in signalling the identity of the character Phaedrus, it was important that one see this in a way that excuses are not made, and allowances not be set forth for what was to become the lone wolf. John Nash too, had his excursions into the bizarre as well, was to know that in the "end of his synopsized life," a certain contention that he had to deal with in this inflection of his disease, as part of his make-up. Was to deal with, while now, he continues to move on with his life. He is aware of the intrusions that personage can do as it infringes from the periphery, as ghosts of his mind too.

To me in reading John Nash's biography in historical movie drama, was to bring attention to what cannot be condoned by exception, when allowing genius to display it's talents, while causing a disruption not only to themself, but to see the elite make allowances for these transgressions. Pattern seeking is not to be be rifting the idea, that we cannot look into the very structure of reality and see what makes it tick? Just that we do not get lost in travelling the journey.

Practising escapism was to deny oneself the responsibility of becoming whole. To allow for genius, as an exception, would mean to not recognize that the intellect is part and parcel of the greater whole of the person called Robert Pirsig or John Nash.

Who of us shall placate failure as a sure sign of genius and allow the student 's failure as acceptable? This was a transgression seen from another perspective and as afterthought realized in a mistaken perception "about broadcasting Phaedrus" as some towering voice from the past as relevant in todays world, because of the location and time in history?

Click on link Against symmetry (Paris, June 06)

While I may use the alias of Plato and look at the substance of his written work, it is also from that view point such a discussion had to take place within the context of the written prose about two people in this Socratic method, that while worlds in the dialogues existed in speech, no such persons were there at the time. Yet, such thoughts are transmitted and established in that historical sense, and moved forward to this time.


Against symmetry (Paris, June 06)


To me there are two lines of thought that are being established in science that in Lee Smolin's case is used to move away from the thinking of the idea of Plato's symmetry by example. To see such trademarks inherent in our leaders of science is too wonder how they to, have immortalize the figures of speech, while trying hard to portray the point of view that has been established in thought. These signatures have gone from Heisenberg to Hooft. And the list of names who have embedded this move to science, as a education tool, that is always inherent in the process. That reference is continually made.

IN this sense I do not feel I had done anything wrong other then to ignite the idealization I have about what that sun means to me, as the first light in a psychological sense. Where it resides in people. How divorce we can be from it while going on about our daily duties existing in the world. That there also resides this "experience about our beginnings." To ignite what the word of geometrics has done in the abstract sense. How much closer to the reality such a architecture is revealed in Nature's way, to know that we had pointed our observations back inside, to reveal the world outside.
