No, black holes are actually invisible because it can suck it Light as well, so no light can escape from the black hole.
black holes arent really things you can right a history pon, but theres a history of their discovery
No
There is a theory that tells that when you fall in a black hole, you are not destroyed but you are "teleported" to a white hole. The wormhole is a inter-dimensional tunnel that connects a black hole to a white hole.
If blackholes reach the earth the earth will destroy. Blackhole are to large it can eat star easily.
Stephen Hawking is currently researching the origins of blackholes and the effects of blackholes on the matter surrounding it.
Albert Einstein.
Gravitation? Yes black holes have enormous gravitation but it is not completely vacuum. When matter gets sucked into blackholes, noone knows where the matter ends up. Black holes originate from a really dense star collapsing on itself like a cookie crumbling if you crush it with enough force.
The supermassive blackholes at the center of galaxies.
In space mostly around groups of old stars
It has both. Hope this helped, WoodWorkingMaster
yes they as scientists found in the middle of the messier galaxy
There are two ways blackholes form:Massive blackholes - these are formed by collapse of stars having more than 3 times the mass of our sun, when the stars die.Micro blackholes - these could have only formed in the big bang. Their event horizons are roughly the size of a proton and their mass is similar to that of a mountain. Unlike massive blackholes, which last forever, these evaporate then explode giving them a limited lifetime.
