Are Strangelets Natural?

Thus RHIC is in a certain sense a string theory testing machine, analyzing the formation and decay of dual black holes, and giving information about the black hole interior.



It is important that you look at the date of this article following, and what has subsequently arisen from "then to now." The title of this post asked a legitimate question and it was answered in response to the disaster scenario's presented to the LHC "recenty?" Check the date on it? Not so recent?

Discovering this raised the conclusiveness about what was comparative to the cosmic ray collisions. This lead us to believe, the microscopic blackhole creation was safe. Becuase it happened all the time in the space above us. Just as we may see the aurora borealis in our observation in the interaction with the sun, so too, in cosmic particle collisions in ways beyond the standard model.

So looking back?


SCIENTISTS ARE OFTEN ACCUSED of trying to play God. But obviously they can't really mimic the feats of the putative Creator of the Universe, and make a universe in the laboratory. Or can they? Before you snort in disbelief, you should know that some serious cosmologists have considered the idea. Indeed, one of them has already had a shot at creating a universe--albeit inside a computer. The idea dates back to the late 1970s, when Andrei Linde, now at Stanford University, and Alan Guth of the Massachusetts Institute of Technology separately came up with the concept of "inflation". According to this idea, an incredibly short, violent burst of expansion occurred around 10-32 seconds after the birth of the Universe. Propelled by concentrated vacuum energy, inflation boosted the size of the Universe from one billionth the width of a proton to the size of a grapefruit. That's what the theorists claim, but showing that inflation really did take place like this is hard... unless, of course, someone can recreate the right conditions in the lab and watch what happens. Linde and his colleagues have already done a dry run on a computer. "Setting up the simulations was hard work, and only on the seventh day did we finish the first series," he reported in Scientific American in 1994, adding in Strangelovian terms: "We looked at the shining screen, and we were happy--we saw that the universe was good!" This isn't enough for Linde: he wants to do it for real. But theory suggests that matter has to be squeezed to densities similar to those in the primordial Universe before such fields appear. No-one has the faintest clue how to create such densities, yet. Linde is sanguine about the dangers involved, if it ever becomes possible. "You can think of our Universe as being like a smooth surface, with one part of it inflating like a balloon. The new universe will be connected to ours by just a tiny passage--what we call a wormhole--the size of a subatomic particle." Quite how we'd know we'd succeeded isn't obvious, but at least there seems little danger of someone tumbling into the new universe by mistake, or anything nasty getting out.


THis one post includes "lots of link"s from the accumulation of my thinkng as a layman. I had gathered these as they unfolded, to help me understand what was introduced to me some time ago by Paul on the question in regards to the "Disaster Scenario at LHC."

Now in regards to "new physics" one needed to see what would come out of such collisions that would be produced, so one had to indeed follow that thinking which I did. How far from the truth of it was what was generated in the public eye distant from what was published by the reputable scientists?

Well you would have to judge for yourself, and "my excuse," well it has been provided for me, so one can say as a layman I am really distant from the current thinking.

So yes before Cosmic Variance and the disaster scenario, it was in our conversations that "Mooreglade of Superstrintheory.com forum" introduced the article of "A Blackhole Ate My Planet" which lead too "Fate of our Planet"

So you see, between then and now, I was able to construct accordingly as I was exposed to the information in regards to "both ways" to which Lubos implies in that statement in comment link?

Okay. Now the stage has been set.

What has been Lubos been saying?

That the connection in "B's question" again sets the stage for further thoughts?

That's just the way of it and who better then student who will make way for further insights, whether it be "Lubos or B?"

In the past my mistake was made to "mirror" Lubos with Peter Woit, because I needed to see what the others may offer in regards to the positions they adopted. Or, another example would have been Smolin and Susskind, who bounced off each other. Or, Gell-mann or Feynman. Or maybe even Plato and Aristotle shhown in the picturte at the top of this Blog?

IN the above case with Peter Woit, I did not learn much? The counter arguments as to why strings were failing in the road to experimental validation(sure we were preoccupied with it's validity then), and how this message was being put out there.

Be sure that more senior people agree with me that it is trivial to falsify that conjecture, including Susskind, Vilenkin, Banks, and others who have looked into it.


So where are we today in regard to strings? Lubo's reference to Banks, Vilenkin, and Susskind already asking these questions is a significant pointer to what has already transpired, and what days, weeks, years, have passed before we see this statement today?

You see how this is done?

Historical Approach of the Sand Reckoner

I should pave the way for how the thoughts that are unfolding this morning.


But nothing afflicted Marcellus so much as the death of Archimedes, who was then, as fate would have it, intent upon working out some problem by a diagram, and having fixed his mind alike and his eyes upon the subject of his speculation, he never noticed the incursion of the Romans, nor that the city was taken. In this transport of study and contemplation, a soldier, unexpectedly coming up to him, commanded him to follow to Marcellus; which he declining to do before he had worked out his problem to a demonstration, the soldier, enraged, drew his sword and ran him through. Others write that a Roman soldier, running upon him with a drawn sword, offered to kill him; and that Archimedes, looking back, earnestly besought him to hold his hand a little while, that he might not leave what he was then at work upon inconclusive and imperfect; but the soldier, nothing moved by his entreaty, instantly killed him. Others again relate that, as Archimedes was carrying to Marcellus mathematical instruments, dials, spheres, and angles, by which the magnitude of the sun might be measured to the sight, some soldiers seeing him, and thinking that he carried gold in a vessel, slew him. Certain it is that his death was very afflicting to Marcellus; and that Marcellus ever after regarded him that killed him as a murderer; and that he sought for his kindred and honored them with signal favors.


First off, as Plato I understand "the secret" of the Building of the Pyramids. Why and what it means as a model of comprehension about the building blocks of nature.

So "carefully think in conclusion" about what this post means as you near it's end. For I had much more to say about it philosophically, but that would be stepping ahead to "now." :)

Anyway


Many physical quantities span vast ranges of magnitude. Figures 0.1 and 0.2 use images to indicate the range of lengths and times that are of importance in physics.


A lot of people do not understand that if you look to the cosmo, you do not just look at what is evident from observation, but that your observation is increased, as you enhance your perceptions about the "real depth" of that universe.

IN "LHC Factoids," presented by JoAnne of Cosmic Variance, some of the tantilizing ideas about the complexity of the information is being discussed. To me, this presents an opportune time to gain perspective from the "bottom up" discussed by Frank Wilczek .

If the sand is melted into a lense or a diamond, what view had been established by Frank that you might say his lense "is" distorted? If you read the article you understand the context, but until then, what use any "mountain/pyramid to climb" if you did not understand the complexity of the information?



Archimedes met an untimely death while deep in thought, pondering a figure he had drawn in the sand. He did not see the Roman soldier approach, sword in hand. The mosaic portrays this historical event


About Dimension

John Baez's link this morning in his comment is important for a lot of different angles... ummm... reasons?:)

So when you are pointed towards the valuation of all these "sand particles," it not that you want to look like an "ostrich and bury your head in the sand," but that you want to retain perspective on the complexity of the "sand castles" that mathematicans like to build? So you tend to look for the technique concerning the point, breadth and width of the evolving statemntement of the projective geoemtries?


A space is a collection of entities called points. Both terms are undefined but their relation is important: space is superordinate while point is subordinate. Our everyday notion of a point is that it is a position or location in a space that contains all the possible locations. Since everything doesn't happen in exactly the same place, we live in what can rightly be called a space, but points need not be point-like. Any kind of object can be a point. Other geometric objects, for instance, are totally acceptable (lines, planes, circles, ellipses, conic sections) as are algebraic entities (functions, variables, parameters, coefficients) or physical measurements (time, speed, temperature, index of refraction). Even so-called "real" things can be points in a space: people are points in the space of a nation's population, nations are points in the global political space, and telephones are points in the space of a telecommunications network.



So of course you always start off with Euclidean perspective, and work from there. So, you have "one" grain of sand? One raindrop? One string? Okay, you get my point yet?

The beginning of the Universe?

I want people to realize where the strings fit in. I can't help but stress that such advances to "the cause" of what perception is necessary had to start off in a "avenue" like all things, this road leads to the universe we have today.



Because it starts off in the analogy of "the string" makes this feature no less important then the "sargeant major" of Robert Laughlin's condense matter theorist view.

    Science People Working the Trades?




    Now how often have we seen the ability of good science people brains tested with actually "construction techniques" in the everyday world? Be it, some calculation on how much concrete is to be supplied in the driveway to drain the water to the drain area in the most appropriate way?

    A Sundeck which need some repairs, to have concluded the types of painting to make it last that little longer? You remember who you are.

    Well, as a "lay person" I am not a very good science person, yet, neither am I a very good builder with little tolerance for constructing on the large scale.

    But I persevered, and challenge myself. Find, that doing it with someone you brought into the world, has been a really enjoyable time. Imagine, a trwenty six year old with out the history building as he has done, leading his poor Father through the time.:)

    The Plan

    So yes, it is always good idea to have a plan for the model which you choose to construct. Ideas, to manifest in real mattered forms. In the following, I seen these things, and should have drawn the plan, but I like to "wing it" in case I need to adjust.

    But hey, that's not very good either. You tend to waste good hard earned money.

    You all know that ole adage, "measure twice, cut once?" I know practise makes perfect.

    Building the aggregate patio

    So anyway I had my own things that needed to be done in accordance with something that we as a family enjoy. While physically we can and do work hard, we find the beauty and peace of sitting under the stars quite tranquil. We like to rest the weary bones in the soothings waters of the Hot Tub.

    So ya, the plan included a Hot Tub and a place to put it. A place "over it" with the Gazebo pictured above, to protect it from the wind, snow, sleet and everything else that nature can throw at you. You see we had one before and being in the open we change lids often which were costly in themself. So this new one, was to be protected to reduce the cost over the long run.

    Also energy concerns were an issue compared to the ole hot tub, which ran electricity as if somebody turned on a tap. Like water conservation, which I had reiterated in my previous posts about our living in the wilds, thes ethings of course are of a concern. New technologies make these things more capable which is another reason we bought a new one.

    Hot Tub Here now the Gazebo?

    As you can see as you click on picture and enlarge it, it also meant putting in new shrubs and plants. Also, you'll notice that there are still "white boards there" with which I had to build the Gazebo over top of the Hot Tub. Not good planning again. Thes ewere used to put baorads acrss as I was then able to work above.



    The roof is to be a clear Suntuff, that has yet to be put up. This will be taking place over the next couple of days.

    SOLAR B and Van Ellen Belts

    SCIENCE GOALS OF SOLAR-B
    To determine the mechanisms responsible for heating the corona in active regions and the quiet Sun.




    There are of course reasons why you want to keep these perspectives together.

    While I have been extolling the virtues of Grace satelitte systems and climate it has been noticed that the developing framework of science here is also important and has been recognized in regards to what we don't see, and what happens in the Sun/Earth relation.


    Univ. of Iowa
    Space physicist James Van Allen, shown here in a University of Iowa photo, was best-known for discovering the radiation belts that now bear his name.


    For me, my "philosphical views" take me to the "basis of all life", and the valuation I have see in how we related things, emotively, mentally, and spiritually with the planet and the lifeforms on it.

    I couldn't help be amazed at the direction of my research over time, and the value the Van Ellen Belts serve as a model, to the human structure as a schema of what goes on in relation to earth's spherical body interactions.

    Shall I dare point out this thought?

    Shall I carry it over to the human being, or the computer screen, that is affected by....? Communciations, that are interrrupt by the value of what the Sun casts off in it's corona?

    Helioseismology

    The science studying wave oscillations in the Sun is called helioseismology. One can view the physical processes involved, in the same way that seismologists learn about the Earth's interior by monitoring waves caused by earthquakes. Temperature, composition, and motions deep in the Sun influence the oscillation periods and yield insights into conditions in the solar interior.


    I keep the "image" in the right index for such a reason.

    The Coming Season of the Aurora Borealis.



    Helioseismology became of interest to me, and the way in which we can percieve this relation. To be able topercieve when the events were to be most illuminating. So yes, I was always enthrall by what I could myself see in space, as I watched going into the fall months as the "aurora borealis danced" in the color displays. To know what was going on in that Sun/Earth relation.

    Last night, under the stars, we looked through my "construction technique of the roof" of the Gazebo, as it divided the night sky of stars into eight sections. We relaxed in the hotub, under a beautiful display of the cosmo.

    Cosmic Rays in Atlas



    Like Piglet describing the Heffalump in Winnie the Pooh by AA Milne, one knows this started out in some fantastical world. More then, the "inkblot" as a comparison leads too/from, a fictional story, and became the fantasy of Alice that had already been mathematically set in motion?

    So, theree are "ground rules" on using the inkblot in comparison to any microstate blackhole


    The flux of cosmic ray muons through the ATLAS cavern can be utilized as a tool to "shake down" the ATLAS detector prior to data taking in 2007.

    Additionally, a thorough understanding of the cosmic ray flux in ATLAS will be of great use in the study of cosmic ray backgrounds to the search for rare new physics processes in ATLAS.



    Again people like John Ellis lead us to the understanding of what Pierre Auger initiated in understanding this relation of cosmic particles and the issue coming to the forefront, in regards to the microstate blackhole production from these collisions.

    It is only today, that I discover the back ground process that was going on here, while it was bein worked out on Sabines's and Stefan's Backreaction site. I didn't relaize I was a "boucing board" from which the "questions in mind" were being initiated. Repeated comments "there" placed here in the comment sections to advance a position on what I thought.

    The momenta of the charged particles are measured from the curvature of their trajectories in a magnetic field provided by superconducting magnets. The volume and strength of magnetic field needed are not achievable with conventional magnets.


    We use each other as spring boards(nudges) to seeing a little further each time. That is defintiely appropriate to developing a good comprehension of the subject at hand, and creating insight to further information values gained in that research.



    See:

    Stefan and Sabines Backreaction site on Backreaction: Micro Black Holes

    A wonderful resource link to cosmic particles demonstrations

    Also my comment at Backreaction, has some more information in the search for understanding on microstate blackholes as well.

    Gravitational Radiation

    How dry this article in comparison to what we can witness in the cosmo?

    One gets this sense of "curvature implied" that the events connected at locations in the universe could have been felt in other locations? What connects them? The spacetime fabric?:)

    If one was speaking and one was seeing beyond the observation of the events shown here, then what is there to say if one cannot accept "the language" while they hold to only what they see? No speculation, no theories, no future?

    Only, the now?

    With the development of quantum mechanics, it was realized that on this scale the protons must be considered to have wave properties and that there was the possibility of tunneling through the coulomb barrier


    So while this information exist here now, how does this help you look at events, or is this information lost?

    Virial Theorem

    A general theorem from the mathematics of physics becomes a useful part of the picture of gravitational collapse. In the context of gravity it can be applied to a finite collection of particles which interact with each other by gravitational attraction. We can attribute to the collection of particles a total gravitational potential energy and a total kinetic energy. The virial theorem states that

    Average kinetic energy = -1/2 x Average potential energy
    One application of this theorem would be to a known mass of hydrogen gas in a proto-star. If you had a good estimate of the mass of the gas and could measure a sample of particle velocities to determine the kinetic energy, then you could predict the kinetic energy as the gas cloud underwent gravitational collapse. So for a given radius of collapse, you could make a prediction of the temperature of the hydrogen gas in terms of the kinetic energy and could make a prediction about when it would reach the ignition temperature for hydrogen fusion.

    Another potential application is to the question of dark matter. If you examine a system of objects out in space and are able to measure the kinetic energy of the system, then you can imply the gravitational potential energy. If the total mass of all the visible objects is too small to give that amount of gravitational potential energy, then the implication is that there is matter there which you cannot see (dark matter). When this has been done for a variety of types of galaxies, there is strong evidence for dark matter (Baez).


    Still the connection "is" in the "spacetime fabric" and all events have to be detailed according to some "relation of value in the energy distributed of itself," as we gaze upon the beautiful events within that cosmo?

    Gravity-Don't Let it Get You Down

    If a inkblot appears on your desk, would you think it appeared in the shape it did to convince you, that what you are "seeing is real?" To you, it may look like someone trying in their attempts to convince you of what a blackhole is?

    These questions greatly disturbed Richard Feynman. His famous paper on quantizing general relativity, in which he first described his discovery of the "ghost particles" that eventually played a crucial role in understanding modern gauge field theories, begins with a discussion of the smallness of gravitational effects on subatomic scales, after which he concludes,

    There's a certain irrationality to any work on [quantum] gravitation, so it's hard to explain why you do any of it. . . . It is therefore clear that the problem we [are] working on is not the correct problem; the correct problem is: What determines the size of gravitation?


    So the fantasy of implying such things as "ghosts" go to the points of what Feynman wants to say? He then shows you this inkblot. Psychologically are you prepared?

    Why do physicists want to study particles?

    A few "cosmic rays" pass through our body every second of every day, regardless of where we are.

    They consist of particles created when high energy atomic nuclei (mainly protons) coming from outer space collide with the atoms at the top of the earth's atmosphere. Such particles are not just electrons, protons and neutrons, but also other kinds of particle.

    Near the ground, the cosmic rays include muons, similar to the electrons but more than 200 times heavier. Unlike electrons, which live forever, a muon will live about 2.2 microseconds, and then convert into an electron and two neutrinos (electron-neutrino and muon-neutrino; these are like a very light neutral version of the electron and of the muon).

    The muons themselves emerge mainly from the decays of other short-lived particles. Some of these particles, called pions, are made from up and down quarks. However, others (kaons) contain a third type of quark, called the strange quark.

    Cosmic matter is then made up of more components than the atoms. In addition to the electron, electron-neutrino, up quark and down quark, we have the muon, the muon-neutrino and the strange quark.


    Do Blackholes Radiate

    The possibility that non-radiating "mini" black holes exist should be taken seriously; such holes could be part of the dark matter in the Universe. Attempts to place observational limits on the number of "mini" black holes (independent of the assumption that they radiate) would be most welcome.
