This is comparable to the wind, in that you can't see it, but you know it is there. You can conclude that there is something, for example, by watching trees or other things moving in the wind.
In the case of a black hole, the effects of its gravity can be seen quite clearly.
After a black hole forms, it continues to exist in space, exerting a strong gravitational pull on surrounding matter. Anything that gets too close to a black hole, including light, cannot escape its gravitational grasp and is consumed. Black holes can continue to grow in size by absorbing matter and merging with other black holes.
None at all.Black holes do exist. They have been observed.
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.
You can't because they suck in light, there for you cannot see them
White holes are theoretical regions of spacetime that expel matter and energy outward, the opposite of black holes which pull matter in. They do not suck up objects like black holes do. However, there is no observational evidence for the existence of white holes in the universe.
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.
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.
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 cannot be detected directly since the gravitational force is so huge it sucks in even the light. in fact, there's no definitive proof that black holes actually exist at all. what we are able to detect directly are the effects of celestial bodies circling a powerful and invisible center. That said, it is assumed that there are black holes in the center of every galaxy i cannot assure they are actually "black"..or that they are "holes" though
No they cannot.

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.
The assumptions are not quite correct.Scientists CAN see black holes. In fact, black holes are among the brightest objects in the Universe. Of course, light can't escape from WITHIN the black hole; rather, what we see is the accretion disk. Also, scientists are PRETTY SURE that black holes are real. As to why it is important: Black holes are fascinating objects by themselves. They also seem to play an important role in galaxy formation.
