Scientists Create a "Black Hole" in a Lab

Physicists working at the Relativistic Heavy Ion Collider (RHIC) in New York, US, have produced what appears to be a black hole in their lab. They say it displays the same characteristics as the natural phenomenon found in space.

The hole is in the centre of a plasma fireball with a temperature approximately 300 times hotter than the suns surface. Beam collisions caused by gold nuclei being fired at near light speed are sucked into the black hole, allowing it to be measured.

The team were suprised when they found the rate of beam absorption to be ten times that of their calculations. It is believed that the particle beams are entering the core and reappearing as thermal radiation.

Nice researching Alex. That was interesting but giveing the wording of the artical I think they have about as many questions as we do....I look forward to followup research on this.

Thanks terrorhertz. Yes, Nastase did say that there was something "unusual about it". Apparently, ten times as many jets were being absorbed by the fireball as were predicted by calculations. I just wonder what will happen if the energy might become too great to control in future experiments. If it really turns out to be a true black hole, and knowing that gravity wells can continue to draw in material, what's to say that it might not get out of control?

At RHIC we don't make a "real" black hole

Thanks for that daav. That sure is one very large black hole. Swallowing a mass of 300 million suns and spitting out gas with a mass of one of a trillion, is almost hard to believe. No wonder the emission is so huge.

I also read about that recent dinosaur soft tissue discovery on sciencedaily.com. I read about it a few days ago, but this article gave more information about it.

Hi Byron, and thank you. Yes I do intend to pursue one or both of those goals. I've made the mistake of using calculators for many years now, so I have a long way to go to catch up with the mathematics of astronomy. And my programming has mostly been doing lots of funny stuff with computer codes and scripts.

The statement by RHIC says that the fireball is completely different from a black hole in the universe.
It seems that the researchers are cautious about their enthusiasm with these results.

It said that the amount of matter produced cannot possibly produce a "true star-swallowing black hole".
Sounds like they're in uncharted territory. They did say that the rapid deceleration of ions as they collide at 10^(-23)
second is similar to the extreme gravitational environment in the vicinity of a black hole.

Thanks Thierry.

....Black Holes and Gravitational Singularities

Exotic gravitational effects may occur at immense densities. Conservative dimensionless
measures of the strength of gravity give 10¯22 for classical effects and 10¯34 for quantum
effects in the RHIC environment, in units where 1 represents gravitational effects as strong
as the nuclear force. The arguments leading to these estimates are presented in Appendix A.
We also note that collisions at RHIC are expected to be less effective at raising the density
of nuclear matter than at lower energies where the stopping power" is greater, while as we
noted before, existing accelerators have already probed larger effective energies. In no case
has any phenomenon suggestive of gravitational clumping, let alone gravitational collapse or
the production of a singularity, been observed....
