I'm just curious about one thing. Is it possible to make or create an artificial black hole?
Felgar said:Though not technically a black hole, Dr. Mallet (UConn) is proposing the use of lasers to bend spacetime artificially. If he succeeds he'll have created the ability to bend spacetime back on itself just like a black hole does but without the annoying ridiculous amounts of mass required to sustain a 'normal' black hole. He's hoping to build a time machine with it... Guess we'll see in a few more years...

All is well at Brookhaven. The RHIC has been up a running for awhile now. Earlier this year they were smacking gold ions together at a whopping 200GeV. Unfortunately, no baby black holes have appeared, just your garden variety quark-gluon plasma.Phobos said:I thought Brookhaven was supposed to have started theirs up already. Was it delayed? (funny side note...I peeked at Google for the answer and the first entry pointed me back to Physics Forums! We so totally rock. )
Are we sure this is a good idea?Chronos said:All is well at Brookhaven. The RHIC has been up a running for awhile now. Earlier this year they were smacking gold ions together at a whopping 200GeV. Unfortunately, no baby black holes have appeared, just your garden variety quark-gluon plasma.
If somehow the "black hole" could become persisitant, it probably would not be a very good idea. You can imagine a sub-microscopic black hole dropping into the Earth and oscillating to an fro, slowly, slowly nibbling away...Garth said:Are we sure this is a good idea?

Few days back I was strongly opposing the idea of creating mini black holes on the Earth and my main argument was that for creating black holes you need a lot of mass but that is not true. After reading the following article I came to know that the only condition to form black holes is that the colliding particles must get so close that the gravitational force between them is strong relative to the other forces.dragonfly said:I'm just curious about one thing.

Chronos said:Correct. Mass is not important, only mass density. The variable is the lifespan of black holes is inversely proportionate to their mass. Black holes created in accelerators would evaporate almost instantly via Hawking radiation. ps: No need to worry about them swallowing the earth. Supernova routinely spit out atomic nuclei [cosmic rays] at far higher energies than we could ever create in accelerators.

An interesting example of another kind of Event Horizon, and the possiblity of studying a mechanism like Hawking Radiation in an earthbound analogue.
qraal said:Sonic black-holes are physical analogues of space-time in which sound plays the role of light. The physical correspondance is near perfect, oddly enough, and a sonic BH should produce Hawking radiation (as phonons of course) but observing them in such an environment will stretch the skill of the experimentalists to the limit.
Currently, there is no known way to create an artificial black hole. The technology and energy required to create a black hole are beyond our current capabilities.
Black holes are regions in space where the gravitational pull is so strong that nothing, including light, can escape. They are formed when a massive star collapses in on itself.
Black holes can be dangerous if we get too close to them, as their immense gravity can pull objects and even light into them. However, there are no known black holes close enough to Earth to pose a threat.
According to current theories, black holes do not last forever. They slowly lose mass over time through a process called Hawking radiation, eventually evaporating completely.
Yes, we can study black holes by observing their effects on surrounding matter and light. We can also use advanced telescopes and technology to gather data and learn more about these mysterious objects.
