(HD) Dark Matter & Dark Energy in the Universe - Full Documentary

See:(HD) Dark Matter & Dark Energy in the Universe - Full Documentary




The Xenon Dark Matter Project






Model of the Cryogenic Dark Matter Search which translates actual data into sound and light. We have not yet had a dark matter interaction, but we have lots of particles hitting the detectors and that is what you are watching. A downloadable version is at my webpage http://www.hep.umn.edu/~prisca More info on our experiment can be found at http://cdms.berkeley.edu and http://www.soudan.umn.edu

There is current data that deals with this topic that has been transformed in how we look at this issue.  I leave that up to viewers to think about all the other bloggers that have already spoken to this. I wll give one link below for consideration.

Analogies Make You Think



See:
Falling into a Blackhole- On Sept. 25, four theoretical physicists — Raphael Bousso (U.C. Berkeley), Juan Maldacena (Institute for Advanced Study), Joseph Polchinski (U.C. Santa Barbara) and Leonard Susskind (Stanford University) — answered your questions about the latest theories about what happens when matter falls into a black hole and how these ideas are prompting researchers to reconsider our understanding of gravity.

Gravity The Movie and the Expanse of Space



Went and saw the movie yesterday. I must say it had a crazy effect on me seeing the movie in 3d.

It seem to capture some of my fears about having lost some constraint on how one is attach to the matters with which we are held bound. The grasping continuously,  of trying to grab onto and hold too, as if the need exists for all humanity to be grounded.

Effectively as a participant once fully engaged, it showed me a glimpse into the future, one way or another, of being involved in the process. While being to old to ever consider such a process now in space exploration, if there is a future life,  I have already glimpsed it,  and seen some of the work I was going to do.

Wishful thinking on my part perhaps, but equally real that the fear of being lost in space, ever so real as to the understanding of what we may call home to many of us. It is as fragile to realize that what we call home here on earth could have ever lost such bounds as to what we all remain attached too. In that moment of realization perhaps to see all around, us, as no longer being held to Earth as the mass between us somehow looses it gravitational hold.

You must forgive me for my layman pondering. How is it that we can change this gravitational connect between the masses without altering the mass of one? It seems to me that there is a  link  to mind somehow in what I come to believe to be true, is an ability to change how that mass is viewed? Is there any scientific proof for this that we can change the laws of gravity, by either injecting something into the space between these masses, or,  by altering the nature of the mass itself?

As Sandra Bullock is shown on the shore,  we find we are safe again.



Such a feeling had been deeply entrenched in my mind as I moved closer to the edge of a viewing point over looking  the Grand Canyon. That such an expanse of space was to have been found with such familiarity,  as in the movie just seen.

So in a way this idea of releasing the matters is a strange thing in my mind as to have ever considered it beyond the materialistic binds with which this process is viewed. That there are other and thought provoking ideas about what the spirit of ourselves can ever be held so tightly so as to see the way in which we are connected to the experiences in life.

What would it mean to have found that the attachments of life can be so easily held in perspective that we can release those things which keep us grounded. Not that we feel safe, but to realize that there is another kind of gravity that holds us to the materialistic binds which make our lives human here on earth.

CERN Courier: AMS-02 provides a precise measure of cosmic rays

Fig. 1. AMS, far left, was installed by NASA on the International Space Station on 19 May 2011, where it is the only major physical science experiment. It will operate there for the station's lifetime of approximately 20 years.

AMS-02 is a large particle detector by space standards and built using the concepts and technologies developed for experiments at particle accelerators but adapted to the extremely hostile environment of space. Measuring 5 × 4 × 3 m3, it weighs 7.5 tonnes. Reliability, performance and redundancy are the key features for the safe and successful operation of this instrument in space (CERN Courier July/August 2011 p18 and p23). See: AMS-02 provides a precise measure of cosmic rays





It's important I think to see the context of particle  reductionism in the proper light  as we examine what goes on in LHC. Doing AMSII work on space station at the same time, we see from space those energies which help us  to understand the naturalness of the work being done.

History of The Fly's Eye Event

Most understand my curiosity with what is happening naturally around us in terms of High Energy Cosmic Events ( It should be stressed that the energy required to move these particles this fast is enormous. Millions of times more energy per particle than humans have been able to create. See- Closure).


The highest energy particle ever observed was detected by the Fly's Eye in 1991. With an energy of 3.5 x 1020eV (or 56J), the particle, probably a proton or a light nucleus, had 108 times more energy than particles produced in the largest earth-bound accelerators. See: Wayback Machine


So for me it is an interesting confirmation about what scientists do with regard to trying to understand these events. How much energy is involved and whether we can create models with which to understand the decay products that are created from.

The highest-energy cosmic ray ever detected was observed on October 15, 1991 by the Fly's Eye cosmic ray detector in Utah, USA. The detector is located in the desert in Dugway Proving Grounds 75 miles southwest of Salt Lake City. The Fly's Eye detects cosmic rays by observing the light that they cause when they strike the atmosphere. When an extremely high-energy cosmic ray enters the atmosphere, it collides with an atomic nucleus and starts a cascade of charged particles that produce light as they zip through the atmosphere. The charged particles of a cosmic ray air shower travel together at very nearly the speed of light, so the Utah detectors see a fluorescent spot move rapidly along a line through the atmosphere. By measuring how much light comes from each stage of the air shower, one can infer not only the energy of the cosmic ray but also whether it was more likely a simple proton or a heavier nucleus.

A Deeper Search for Building Blocks of Nature

National High Magnetic Field Laboratory
The strange properties of superconducting materials called “cuprates” (bismuth strontium calcium copper oxide is shown here), which cannot be described by known quantum mechanical methods, may correspond to properties of black holes in higher dimensions.
According to modern quantum theory, energy fields permeate the universe, and flurries of energy in these fields, called “particles” when they are pointlike and “waves” when they are diffuse, serve as the building blocks of matter and forces. But new findings suggest this wave-particle picture offers only a superficial view of nature’s constituents. See:

Abdus Salam Movie – The Dream of Symmetry



The movie presents the extraordinary figure of Abdus Salam of Pakistan, who not only was an outstanding scientist but also a generous humanitarian and a valuable person. His rich and busy life was an endless quest for symmetry, that he pursued in the universe of physical laws and in the world of human beings.See:Abdus Salam Movie – The Dream of Symmetry

Nima Arkani-Hamed Lectures



Nima Arkani-Hamed on developments in Physics and future vision






The Salam Lecture Series 2012, with a week-long series of lectures by renowned theoretical physicist Nima Arkani-Hamed. Giving his audience a panoramic view of 400 years of physics in his first lecture, Arkani-Hamed provided insights into the various concepts that have dominated the world of fundamental physics at different points in history. "Everything that we have learned [over the past 400 years] can be subsumed with a basic slogan, and the slogan is that of unification," he said. "More and more disparate phenomena turn out to be different aspects of the same thing." "Physics," he stressed "forces you to remove artificial distinction between disciplines.
