[QUOTE="freyar, post: 4563936, member: 40227"] Umbran and LT both make excellent points here, and they're quite correct. I'll just throw in that we actually know quite a bit about black holes. By saying that we've only "inferred" the mass of a black hole, for example, you have to say that we've only inferred the mass of the sun or the earth. Our ability to make some of these measurements in astrophysics may be relatively new (identifying where a black hole is and how much mass it has, for example), but the physics involved in the calculations is centuries old. Not to mention, just repeating what has been said upthread, the entire LHC experiment has been repeated many times over not only on earth but in stars all around us by cosmic rays. If it were possible for a mini black hole to form and swallow up a planet or star, [i]we'd have seen it happen already.[/i] [/QUOTE]
