First artificial black hole created?

As an unexpected side effect of an experiment, Horatiu Nastase (of Brown University of Providence, Rhode Island), found something which looks like a black hole:

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. This fireball, which lasts just 10 million, billion, billionths of a second, 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 it.

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 is thought to fall into a black hole and come out as "Hawking" radiation.

However, even if the ball of plasma is a black hole, it is not thought to pose a threat. At these energies and distances, gravity is not the dominant force in a black hole.

    Well, as a true blogger, I subscribe to the tradition of posting a certain percent of unrelated stuff on my blog 🙂
