High-energy cosmic rays are invading the Earth's atmosphere can form a microscopic black hole, say Greek and Russian scientists.

As you know, the usual black holes are born in the time of the explosion big star at the very end of her life. The outer layers of the star in this explosion carried away, and the core, in contrast, can be compressed into a superdense "singularity," where gravity is so strong that nothing — not even light — can not leave the confines of the newly formed black hole.

Theodore Tomaras, a Greek physicist from the University of Crete in Heraklion, and his Russian colleague Andrey Mironov and Alexei Morozov theorizes that high-energy cosmic ray particles can create black holes when they collide with molecules in the Earth's atmosphere. These black holes are very small and invisible, their weight is only 10 micrograms says Tomaras. These black holes are so unstable that explode with the formation of many new particles within a billionth of a billionth of a billionth of a second.

Scientists believe that these black mini-holes could help explain the puzzling results from cosmic radiation sensors in the Bolivian Andes and the Pamirs (Tajikistan, Central Asia) — talking about the so-called "Centaur".

The sensors did record rainfall of particles — the stages that are formed during the passage through the atmosphere, some high-energy cosmic-ray particles interacting with atmospheric molecules.

In 1972, in the Andes sensor registered the mysterious picture. Unlike normal development stage of the cosmic radiation particles, this stage was unusually rich kvarkosoderzhaschimi charged particles, wherein the number of particles in the lower part for the detector paradoxically exceed the number of particles in the upper part. This phenomenon was called "Centauro", because its structure associated with the researchers with a relatively small head of a mythical polucheloveka-poluloshadi on a surprisingly large body.

Since the camera in Bolivia and Tajikistan have registered more than 40 such Centauro-like events. They also say a "minikentavrah" and "antikentavrah." These phenomena have been proposed many explanations — from hypothetical quark "nuggets", occasionally falling into the chamber, to the exotic, which is manifested in conventional nuclear interactions between particles at extremely high energies. Exploding black holes near the sensor, according to the Greek and Russian scientists are also in line with the sensors paintings.

The researchers hope that a detailed analysis of future events centaur-like explosions and computer simulations of black mini-holes help to solve this puzzle.

The consequences can be staggering. In addition to the evidence of the existence of such tiny black holes, it would reveal the hidden dimensions in the universe. In addition, it would give physicists know that CERN (Geneva particle physics laboratory) in a short time can be "tailor-made" to get in a lot of these same black hole. Particle collisions in the LHC (Large Hadron Collider) should begin in 2007. According to calculations, the energy of these collisions would be enough to create thousands of black holes every day.
