Einstein

 

Einstein judged the energy movements in his famous equation E=MC² based on the limitation related with the speed of light, but now we have realized that the cosmic rays are six times more energetic* (for more details read footnote) than what the theory would allow

 

 

 

 

* The Highest Energy Cosmic Ray Event Ever Recorded

On a dark and clear night in October 15, 1991, the Fly's Eye detector in the west desert of Utah, U.S.A. detected a cosmic ray shower of extraordinary energy.

 

Cosmic Ray researchers were dumbfounded when their "Fly's Eye" detector in the high Utah desert turned up with an incoming particle from space with an energy six times higher than their theory allowed. Two years later, on the other side of the world, a Japanese detector recorded another of these "impossible" events.

 

The origin of this particle is a mystery. No known process can produce a particle with this much kinetic energy. It also must have been produced fairly locally as particles of this energy interact with photons from the 3K microwave background and lose energy. No known active galaxy or radio galaxy has been observed within the region of its origin.

 

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 Utah researchers measured the energy of the unusual cosmic ray event in 1991 to be 320 EeV. They were stunned by their observation. They had previously believed that such energetic particles could not exist in the universe, because theory said that the particles should rapidly lose their energy in collisions with the universal microwave background left over from the Big Bang. Thus, very high-energy particles now pose a cosmic mystery that has rallied a worldwide collaboration to begin planning the vast new detector called the Pierre Auger Cosmic Ray Observatory.

 

Akeno, Japan, a village about 120 km west of Tokyo, is the home of the world's largest surface array for detecting very high cosmic ray airshowers. On December 3, 1993, the AGASA array recorded a very large airshower. This very special event was particularly well measured because the airshower fell completely inside the detector array and arrived from a nearly vertical direction. The airshower was produced by a cosmic ray with an energy of about 200EeV. This is the highest energy cosmic ray observed at AGASA; and, like the Fly's Eye event in Utah, it has an energy well above that expected from any known source.
