Lab fireball 'may be black hole'
Creating the conditions for the formation of black holes is one of the
aims of particle physics
A fireball created in a US particle accelerator has the
characteristics of a black hole, a physicist has said.
It was generated at the Relativistic Heavy Ion Collider (RHIC) in New
York, US, which smashes beams of gold nuclei together at near light
speeds.
Horatiu Nastase says his calculations show that the core of the
fireball has a striking similarity to a black hole.
His work has been published on the pre-print website arxiv.org and is
reported in New Scientist magazine.
When the gold nuclei smash into each other they are broken down into
particles called quarks and gluons.
These form a ball of plasma about 300 times hotter than the surface of
the Sun. It can be detected because it absorbs jets of particles
produced by the beam collisions.
But Nastase, of Brown University in Providence, Rhode Island, says
there is something unusual about this fireball.
Ten times as many jets were being absorbed by the fireball as were
predicted by calculations.
The Brown researcher thinks the particles are disappearing into the
fireball's core and reappearing as thermal radiation, just as matter
falls into a black hole and comes out as "Hawking" radiation.
