Because planets and stars have went into them and got destroyed.
No
People believe that CERN was able to create black holes because of the work they do with particle accelerators.
Whoever said this seems to think that there is not enough direct evidence for black holes. However, I understand there is enough evidence to believe that black holes actually exist - including the observation of many, many objects that can only be black holes.
Some people destroy things to let anger out and think it is funny when then destroy other people's or their things.
Some scientist think that quasars may be caused by black holes, but they are not sure how this happens. Please dont copy. Use your own words! - Anonymous <3
No, that doesn't seem likely.
Probably some people find it hard to believe. Some decades ago, it was believed to be a mathematical curiosity, something that didn't occur in real life - precisely because they are so extreme. However, nowadays it is generally believed that black holes certainly do exist.
there is no aswer to that question, because we know almost nothing about the black holes
Astronomers think that the areas around black holes suck everything in like when a tub drains. But black holes are large amounts of matter that is packed into a small area.
I think they are black because I saw a nonfiction movie about black holes and the pix from a sattelite showed them black. they either have no color or we can't see what color it is, because black holes suck in light, and anything else within a certain distance. a black hole is formed when a star combusts and its gravity absorbs itself and anything else.
Scientists think quasars are supermassive black holes in the process of consuming enormous amounts of matter.
Yes, I think so. Everything must lead somewhere.
