Basically a black hole is a star, well a blue star most likely. A blue star will get bigger and explode in what's called a super nova. If there's still enough of the star left it will squash itself down into an atom! Pretty Small! A black hole pulls things in by gravity, when something gets smaller the more gravity it has so imagine how much gravity the squashed up star would have! So basically black holes do exist.
There is a lot of evidence that they do, indeed, exist.
It isn't known whether micro black holes - usually called primordial black holes - exist at all. If they do exist, they can be at any random location of space.
yes. some black holes are predicted to be the size of an electron.
Schwarzschild black holes. Named after the scientist who proved mathematically black holes can exist.
Black holes did exist in 1999, and long before that. While black holes cannot be observed directly, they have been hinted at having existed by Einstein. The first real recording of the side effects of a Black hole was in 1971.
The scientific consensus does not support Stephen Hawking's assertion that black holes do not exist. Black holes are widely accepted in the scientific community based on observational evidence and theoretical predictions.
Black holes, or singularties, apparently exist in different sizes.
None at all.Black holes do exist. They have been observed.
1) It isn't known whether aliens (in the sense of extraterrestrial life) exist. 2) It isn't known whether wormholes exist. 3) No aliens are required to explain black holes; black holes form quite naturally as a result of the collapse of a massive star.
Yes.
It was to dark to to see
black holes The black hole we see is the Event Horizon. Its realy not a hole. Just a spherical region in space where matter ceases to exist.
