yes. some black holes are predicted to be the size of an electron.
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.
There is a lot of evidence that they do, indeed, exist.
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.
No. A black hole can be a very condensed star. It's also possible for "mini" black holes of less than stellar mass to exist. But in no case would it be possible to describe one as an "expanded" star.
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.
White holes are theoretical objects that are the opposite of black holes, expelling matter instead of absorbing it. They are not considered to be dangerous like black holes, as they do not have the same gravitational pull or ability to trap objects with their intense gravitational force. White holes are not thought to exist in our universe.
