The odd thing about black holes is that they could potentially come in any size - they could even be microscopic. An object is a black hole if its radius is smaller than its Schwarzschild radius, given by the formula r = 2Gm/(c^2), where G is the gravitational constant, c is the speed of light, and m is the mass; this holds true for any mass - a black hole the mass of our sun would be about 3 km radius; one the mass of earth would be about the size of a marble. The largest known black hole to date is over ten times the size of the orbit of Neptune - and the smallest could be immeasurably "thin". The smaller black holes are believed to be unstable and 'evaporate' the most quickly due to the Hawking radiation mechanism, and so, they may not last for very long.

Can black holes dies?
Black holes do not die but they can evaporate.
Why are black holes round?
Black holes are round because they are formed from dead stars and white holes. As you can guess a star is a sphere and that is why black holes are round.
Are dead stars black holes?
Yes. They get sucked into black holes all the time!
What do very large mass star become at the end of their life cycle?
The most massive stars will die as black holes.
WhAT feature is found with Kerr black holes but not schwarzschild black holes?
Ergoregion

What were black holes before they turned into black holes?
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
