That is really not known.
My theory is no, and apparently not. the black hole do not destroy but do not let out usual light, it do swallows the objects but it is not really known what happens next other than the swallowing, it is also known IN THEORY to be many black holes that is to small to be affected by around us too.
and we also have wite holes.
Black Holes can destroy anything in their path. Only when the 'Hypergiant' is within range of the Black Hole.
Black holes completely destroy objects the enter them.
Black holes do not actively seek out planets to destroy. However, if a planet were to get too close to a black hole, the intense gravitational forces could disrupt or even pull the planet into the black hole. So, in that sense, a black hole has the potential to "kill" a planet by tearing it apart.
Yes, that's where they are. A black hole on Earth would utterly destroy the Earth, in a very short time.The existence of black holes is now generally accepted, by the way.
no because black holes can only form through supernovas.
Black Hole simply cannot be destroyed because Black holes have so much Gravity That even light cannot pass or go from near the black holes. Black Holes pull the object passing from 10,000,00 (10 Lakh) away from them. So nobody can go near them to destroy it
Only Micro Black Holes May Be Able to evaporate but this is not proven.
the sun can be destroyed by the molecules of the oxygen in the high quantity .the third form of helium and the oxygen can havethe capacity to destroy it black holes in the large quantity can destroy earth.
Because planets and stars have went into them and got destroyed.
Except for supemassive black holes, no. Most black holes have about the same mass as a star, but the event horizon is only a few miles across.
No -- it only has volcanoes.
You can't use spectrometers to detect black holes. Telescopes are the only way to detect them.
