Well they are playing with fission, what the sun is made of.
Question, have they ever actually proved a black hole or is it still a generally accepted theory.
The existence of a black hole can't technically be "proved" because no light or other type of radition can escape it so we can not possibly "see" one or what it is doing. What we (meaning the science guys in the white coats, not working class dweebs like me) do is infer the existence of a black hole by analyzing rotational dynamics of large rotating masses (meaning galaxies) and then figuring out what type of central mass can attract and hold in gravitational equilibrium all the stars, gas, and the long theorized but not seen cold dark matter (Tau, muon, and electron neutrinos and their anti particles are a candidate for the CDM). Then there are the supposed graviton, don't even get me started there, oy my head hurts from them.
So yeah, most of what we know about black holes is comes from theory, but there has been a lot of observational science that confirms the existence of black holes-the science predicts, and we observe, and the science is confirmed. Most of the time. Our galaxy has a supermassive black hole at it's center with the mass equivalent of a few million of our suns. Looking at the big ol' picture, black holes fit the data set.
There is a situation where a rotating black hole can give off observable radiation as it's angular momentum is converted as it slows down and changes into a Swarzschild black hole from which nothing is emitted and about which nothing can be directly observed.
Then there are the "big bang" black holes also called primordial black holes that were formed at the beginning and are what some fear could be formed during the incredibly high energies and densities that will result from a fully functional LHC. These black holes are small, and small in a way that can not be adequately described, but do have the potential to accumulate matter and eventually grow to a size that means something to us, creatures who live in and are influenced by classical mechanics. Not at all likely, but can not be dismissed.
Well, in the end, all this and $1.50 will get you a cup of coffee at 7-11 tomorrow morning but black holes are real, they do exist, and are part of the way the universe is unfolding to us as we explore its mysteries.
Excuse me now while i go clean out the protein skimmer-it's filthy.
