5. Wow!

And just how long does one think a black hole exists?

From before Hawking's theory that black holes do eventually evaporate, it was thought that black holes are forever. They still kind of are, being that w/ Hawking's theory, black holes evaporating, it takes billions and trillions of years to evaporate. I don't recall his specific theory at that time, but of course it was fascinating as usual.
