Akeno Giant Air Shower Array (AGASA)

A Quantum Gravity in the Lab a meeting held in regardsEcho: DDR as a Test Model was introduced by Bee of Backreaction.

I thought it important that I give some background on what had transpired here to allow me to make certain comments in face of what they are proposing there in QGL.

The historical background to this process is very enlightening when we come to investigate what the universe is doing in relation to what experiments on earth. This "correlation" is an important one these two experimental processes in how we see interactions of high energy particles.

One day, some bright, enterprising physicist, perhaps inspired by this article, will complete the theory, open the doorway, and use the power of pure thought to determine if string theory is a theory of everything, anything, or nothing.

Only time will tell if Einstein was correct when he said, "But the creative principle resides in mathematics. In a certain sense, therefore, I hold it true that pure thought can grasp reality, as the ancients dreamed."Michio Kaku

Having done this research on my own I was thinking already in context of the high energy particle collisions that were being recorded. In my blogging experience, I was some upset when I could no longer locate the article I did on the Fly's Eye and the oh my God Particle. "Revisited" help to point to this information obtained from wikipedia, but I had it long before.

John Ellis was again instrumental here in pointing to information from the Pierre Auger experiments and is supplied in the labels


shows arrival directions of cosmic rays with energies above 4 x 10¹⁹eV. Red squares and green circles represent cosmic rays with energies of > 10²⁰eV , and (4 - 10) x 10¹⁹eV , respectively.

We observed muon components in the detected air showers and studied their characteristics. Generally speaking, more muons in a shower cascade favors heavier primary hadrons and measurement of muons is one of the methods used to infer the chemical composition of the energetic cosmic rays. Our recent measurement indicates no systematic change in the mass composition from a predominantly heavy to a light composition above 3 x 10¹⁷eV claimed by the Fly's Eye group.

Knowing that such high energy particles did indeed react with what we measure in the Sno or Ice Cube was just one more part of the neutrinos from the new physics that were being developed as well.

MAGIC is an imaging atmospheric Cherenkov telescope or IACT that has started measuring since the commissioning ended in late 2004. The project is funded primarily by the funding agencies BMFB (Germany), MPG (Germany), INFN (Italy), and CICYT (Spain).
