Chroot: The type of matter is not relevent at all. All you need to do is to put enough matter into a small enough space that its escape velocity exceeds the speed of light. Viola, you have a black hole. – Warren
Aki: Aren’t they presently creating baby black holes in labs right now?
J20QU3: I wouldnt of thought so, they may be trying but even for a baby black hole u need a huge mass first.
Da Willem: You only need a huge mass density. But the problem (or I guess we should count ourselves lucky) with baby black holes, is that they evaporate very fast.
NANOTEC: they are creating very very small blackholes, the size of a few protons. the part that is tough, is the sustainability. the minuature black holes created evaporate very very quickly as well. from what i guess, CERN(when finished) will help out with this part of the process.
Chronos: There is reason to believe you need at least a planck mass to form a black hole [whose schwarzchild radius would be a planck length]. The limit may, however, be lower if certain higher dimensional theories are correct. In that case the Large Hadron Collider at CERN may be able to produce them. At present, none have yet been created of any size in colliders, so far as anyone knows. If the planck mass limit [~10E19 Gev] holds, we will never create one.
NANOTECH: How could we benefit from creating these black holes at CERN?
Nereid: I too am curious to know why NanoTech thinks mini-black holes have been created in colliders – AFAIK, there’s nothing in the data from any collisions that even hints at such production. Further, if they could be made in colliders, there’d be plenty of them formed from UHE cosmic ray collisions with N or O nuclei (in the air) – again, no hints of such in all the CR data.Mini-BHs would evaporate through Hawking radiation – at least that’s the theory. As no one has observed a mini-BH, this theory has not yet been directly tested (although it is consistent with a large body of indirect experimental and observational data).
You’re probably right about today’s nukes not having the ‘oomph’ to create a black hole. I hadn’t really thrown any numbers into the calculation. Focusing them precisely enough (smaller than the radius of an atom
) would probably be a huge problem too. It would probably still be easier than dragging 3 SM’s of material together, but it’s many, many years down the road, if it’s possible at all.For the sake of comparison (to the 1019
GeV number Chronos mentioned), what energies are the latest and greatest supercolliders producing?
It’s the thought that counts, I reckons.
