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.

Where in space are black holes?
Black holes can be found anywhere in space.There are 2 types of black holes.Stellar and super massive black holes.Super massive black holes can be found in the middle of every galaxy including our own milky way.Stellar black holes can be found anywhere in space.

Are black holes moving?
Yes black holes are moving but they have no sense of direction..
WhAT feature is found with Kerr black holes but not schwarzschild black holes?

What can you say about black holes?
Black holes were stars that were so massive that they collapsed on itself. The gravity in black holes is infinite and more you get closer to it, more time gets slower. Black holes suck all matter that is too close. Even light can't escape Black holes.
What are the deep holes in the universe?
Black Holes.
