Can we see black holes from the Earth?


Yes, we can but not directly. We can see the effect they have.Basically a black hole is a star that's died, that's collapsed. Unbeknownstto many people many stars are in fact double stars or binaries. The deadstar, the collapsed star can form a black hole. The gravitational fieldsare intense. It sucks material from its companion star and forms what wecall an accretion disc around it. The accretion disc emits x-rays and weknow of many stars that are x-ray stars and these are black holes.
