Has the existence of black holes been proven?

Question

Or it just a theory?

Answer 1

Proven beyond shadow of doubt..

Answer 2

This is a difficult question to answer.

First - There are theorys that say a black hole must exist and they will have certain properties. These properties predict that the black holes should behave in certain ways such as produce radiation in a particular form and gravitational effects. Keep in mind that theorys may never be proven through observation, just disproven by observation.

AND, this behavior has been seen in the universe through observation. i.e gravitational effects, radiation sources etc. Again, these observations do not prove the theory.

BUT, there are other theorys that can also explain why we see such behavior. These other theorys use other methods to explain the same observations.

BUT again, the theorys for black holes are widely accepted.

SO - to answer your question, it is a theory that has not been proven.

Sorry for a round about answer - But this is what happens in the areas of research.

Answer 3

It is generally accepted that black holes exist. All of the evidence fits the theories and the theory is used to help understand galaxy evolution (including our own).

It may be that as we learn more the nature of "black holes" will be found to differ somewhat from our current ideas and visualizations, but no doubt 100 years from now astronomers will still talk about black holes (even if they call them something else).

Answer 4

It is a proven theory. Several holes exist

Answer 5

Black holes may or may not exist. If they do exist, they are invisible, weigh billions of tonnes, and are smaller than a kernel of corn! While they have become popular with science-fiction buffs in recent years, black holes were first proposed some 200 years ago by French astronomer Pierre Laplace.

Laplace reasoned that a star must collapse when it dies, that is, when it consumes all its fuel. Because of its enormous gravitational pull, it would cave in on itself. It would shrink to the size of the moon, down to the size of a basketball, then finally it would effectively have no size at all.

When a star collapses below a certain radius, it would become so dense, and its gravitational pull so strong, that even light could not escape (hence the name ‘black hole’). Matter inside a black hole would be so dense that a piece less than one centimetre across could weigh as much as planet earth!

No black holes have yet been positively identified, and not all astronomers accept their existence. But even if black holes do exist, they give no support to the theory of evolution. Black holes are simply in line with the fact that the universe is decaying. Things do not spontaneously improve and become more orderly, as evolution theory would have people believe. They decay, run down, and lose their orderliness.

Answer 6

They do exist in the middle of galaxies ,it is the only thing with enough Gravity due to its mass that could hold all the solar systems in orbit around it. The galaxies May be 150 to 200 light years across. So we don't see the black hole but we can see that sons are disappearing in the galaxies center.
The force of this monster is beyond understanding.

Answer 7

Yes! Granted, no one has actually SEEN a black whole, since you simply can't physically see one. But through mathematics and round about ways, they have been proven to exist.

Answer 8

I believe so.

You can see lots of pictures of black holes on space websites, perhaps. Some are colossal, but they can be small as well. No one really knows what is inside of a black hole, but it has been proven mathematically, so I'd say yes.

Answer 9

A black hollow is seen a "dark count" merchandise. you could not see it through fact it rather is dark; utilising a telescope to look quickly on the black hollow, even though in case you knew precisely the place to look, does not help you be certain something. watching its consequences is the only thank you to appreciate that a black hollow exists interior of reach.

Answer 10

there has been proof of black holes in the 80s. scientists took long-frame pictures of some areas, and a few of those showed stars getting sucked in somewhere in a circular pattern. so yes, there are black holes.

Answer 11

Yes, it has been proven.

And they've found some, and are tracking them.

I'd expect there to be something on the NASA site - especially as they'll be trying to divert attention from the fact they lost the moon landing records.
