Cosmic Rays Collisions and Strangelets Produced?

I like to think of
Enlightenment in another way Jaffe:)

While we had focused our attention on the airs about the earth, how would it been possible for us earthlings to push back the limitations on on our views that we could have seen cosmological data in context of all that we do in the environment?

See QuarkStars on this.

The collisions are strange: PHENIX can identify particles that contain strange quarks, which are interesting since strange quarks are not present in the original nuclei so they all must be produced. It is expected that a Quark-Gluon Plasma will produce a large amount of strange quarks. In particular, PHENIX has measured lambda particles. There are more lambda particles seen than expected.

I thought I would go over existing post I made in April of 2005 (se revised version below)and correct some of the links that would be more appropriate to information released in the Blogs of Reference Frame, Cosmic Variance and Not Even Wrong's site about "Amanda and ICECUBE."

Exotic physics finds black holes could be most 'perfect,' low-viscosity fluid

Son and two colleagues used a string theory method called the gauge/gravity duality to determine that a black hole in 10 dimensions - or the holographic image of a black hole, a quark-gluon plasma, in three spatial dimensions - behaves as if it has a viscosity near zero, the lowest yet measured.

These characteristics of superfluids are very interesting things to consider, as well as what is prodcuerd in "this action" as we are taken to the supefluid created. Think indeed, that this blackhole "is" the superfluid, and the strangelets, what are these? These never existed, until the superfluid was created?

But in the 10 dimensions of string theory, the fluid of a black hole isn't like other fluids. Space-time is considered to be flat in our perception, Son said, and five of the extra dimensions are compacted into a small, finite sphere. In the remaining dimension, however, space is curved. Evaporation doesn't occur in this dimension, he said, because as particles radiate from the fluid they strike the curved edge of the dimension and are sent bouncing back into the black hole.

These links help set up the thinking for information outside of LHC, that was given for perspective back earlier by John Ellis. The leading perspective on Microstate blackhole production was given then as well in the post with Quark Gluon perspectives, about strangelets produced.

While I had thought these relevant to Dark energy creation in our Cosmo, I did not point directly to the nature of these strangelets gathering at the center of our planet. You had to follow all these posts in order to understand the effect of microstate production, not only in RHIC or LHC, but in the cosmic perspective gained from Pierre Auger experiments as well.

I gave early history consideration so that you might understand a early concern of what mankind might have garnered in thinking, when in actuallity, this was happening naturally every time the cosmic rays penetrated the airs around the earth.

You might well see now that these considerations have been logically followed and there has not been much help as I had been laying the ground work for how perspective is garnered about gravitational considerations. These though are quickly dissipating blackholes created in the airs, around this planet.

Cosmic rays are nuclei and elementary particles always falling very fast on the earth from the universe. Enormous number of cosmic rays are always passing through our bodies. Cosmic rays was discovered by Victor Hess, who is an Austrian physicist, on 1912. He went up to the high altitude of 4000 meters by a balloon and found the ionization rate of the atmosphere is raised at the higher altitude by cosmic rays. After that, cosmic rays have been studied extensively and progressively, and mysteries in the Universe and the Nature are being revealed.

Cosmic rays come from the neighborhood of the Earth and also far galaxies. Galactic and extra galactic cosmic rays are considered to be accelerated at dynamical astronomical objects, such as supernova remnants, neutron stars,and active galactic nuclei. After far-reaching long traveling, they plunge into the atmosphere and bring about nuclear interactions with nuclei of oxygen and nitrogen in the air. The extraterrestrial cosmic rays which come from outside the earth are conventionally called primary cosmic rays, and newly produced particles via the nuclear interactions are called secondary cosmic rays. The main components of the secondary cosmic rays are muon, neutrino, electron, gamma ray, and neutron. While electrons and gamma rays are absorbed into the air, muons and neutrinos can be observed even under the ground.

Of course, this could all be speculation and misconceptions garnered in wrong thinking. So I'll leave it to the experts to correct the disemmination that would affront theoretical positions and hopefully I'll see such corrections. :)

Update: Bloggery updating does not seem to be working, so I will recreate the post here for examination.


Cosmic ray experiments must overcome tremendous obstacles. The flux of particles above 1019 eV is extremely low (about 0.5 km-2yr-1sr-1), so detectors need to probe a large effective area to detect sufficient flux. This requires earthbound observatories. Consequently, the high energy particle is detected indirectly, as cosmic ray primaries entering the Earth's atmosphere interact with atmospheric nuclei to produce large cascades of relativistic secondary particles known as extensive air showers.

It somehow seems appropriate, that having been given some hint fom John Ellis of his research and interests, that the historical record could some how be brought into view. The appearnce of these references enhance later log entries on this site. A sort of moving backwards to get to the esence of what has happened in astrophysics and the journey tounderstand the nergies involved that speak to the idea of particle shower creation that had been consistent with reductionistics view we have gone through in the research of string theory.

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. The origin of the particle is unknown. At such a high energy, and with its assumed charge, the path of this particle through the cosmos would have been relatively unaffected by galactic and intergalactic magnetic fields. Yet no plausible astrophysical source is known along the arrival direction, within the maximum possible source distance imposed by collisions with photons of the cosmic microwave background. This event remains a mystery! It is clear that it existed, but there is no obvious explanation for its source.

These are some of the links that follow the early hisotry of our observations, so that we underrstand well that such cosmic rays are still viable arena for the understanding of these interactions. Sean Carroll may create the April's fool joke on mass migration from particle reductionistionism to astrophycics, but the truth is what is learnt is very applicable to both arenas and what had been learnt, can never be forgotten as we move our observations to the FLY'EYE

  • Collision Course Creates Microscopic "Blackholes"

  • Pierre Auger Observatory

  • Cosmological and Microstate Blackholes

  • Early history developement is sometimes important to understand the trends that intermingle began in branches of High Energy Particle Research and Cosmic particle research. We understood well the limitation that we would run into for the size of the coliders necessary for such observations that having understod the limits reached in this regard we see where one branch will push us to consider the world around us and the inertactions developing towards the understanding of thes ecosmic showers that we are experiencing.

    Extremely energetic cosmic rays interact with the cosmic background photons via pair creation and photopion production and lose their energies during their trip. Therefore there is upper limit of distances which they can propagete in the space with a given energy. The above figure shows this limit (so called attenuation length) in case of cosmic ray protons. You see the 2x10^20 eV particles cannot propagate longer than 30 Mpc (100 million light years), which sets the limit concerning the location of possible sources.
