Astronomers say that there are several, possibly many, black holes, all a long way from Earth.
no the galaxy is way to big for a black hole to do much in fact we now know that there is a supermassive black hole in the center of our galaxy right now.
It is now widely accepted that all galaxies have a massive black hole at their centre.
people now know more about the black hole.
black hole sun, now get the rest by yourself :D
Whatever was in the spot in the sky that the black hole now occupies would no longer be there.
None, really. At least, for us, and now. A black hole can be dangerous if it's very massive (such as a supermassive black hole). But mainly, a black hole would be completely harmless, unless it gets close - and the nearest known black hole is at a distance of about 3000 light-years. Even a supermassive black hole would be harmless at such a distance.
there is a game just like that out now
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.

If it could have we wouldn't be alive NOW.
If we were, you would certainly notice. So no we are not.
A black hole originated as a star, that is, the star converted to a black hole.
As Stephen Hawking demonstrated mathematically, black holes can evaporate by emitting what is now known as Hawking radiation. The smaller the black hole, the faster the rate of evaporation. And they can evaporate until they are completely gone.
