Do you believe in black holes, worm holes, or/and white holes in space?

Question

Black holes are stars that have collapsed and become extremely dense, then collapse on themselves. They pull everything into them. A white hole is just the opposite--it expells everything and, thus, be impossible to enter. A worm hole is suppose to connect folded space and is very unstable. If stable, time travel might be a reality!! What do you think?

I believe that any kind of different thinking is well worth spending time on.

Answer 1

Black holes-- yes there is extensive evidence that they do exist.

Worm holes-- no real proof, but I like to think they exist anyway

White holes-- no, black holes don't lead to anywhere, they just grow in size by crushing everything to subatomic sizes with there immense gravity. If something does nothing but spew matter, it would have to either have a fuel source (black holes don't go anywhere and wormholes are worm holes at both ends) or it would have to have a lot of matter to spew. It also would have to have almost no gravity otherwise the matter would stay there. Matter is what creates gravity, so therefore the second possibility is defunct.

Time travel-- I do not beleive in T. travel, but my reasons are completely unfounded by current science, AKA they are personal theories about the yet unprovable aspects of space and time which would take longer than my contradiction of white holes to explain. However, in reference to one person who answered about T. travel, just to play devil's advocate, how do you know you aren't surrounded by time travelers?

Answer 2

I believe in black holes because there's lots of scientific observational evidence that they do exist. The same thing can not be said for worm holes and white holes. They are nothing more than interesting theories.

If worm holes do exist, and we could travel through them, it would not constitute time travel ("time travel" being the physical movement back to the past or ahead to the future). A worm hole would simply be a short cut through space between different locations. Such a trip would take less time, but that isn't the same as time travel. It's like if you drive from point 'A' to point 'B' in one hour, but then find a short cut that requires only 30 minutes for the same trip.

Answer 3

In reality a black hole crushes matter, then the matter becomes part of the black hole - a black hole doesn't actually go anywhere, it's not a "hole". However, in theory some believe a white hole will emit whatever a black hole sucks in. Like a wormhole? Not really. You couldn't use a black and white hole to time travel in theory. In theory a wormhole is a short cut through spacetime (commonly used in science fiction). You can safely go through a wormhole, and come out elsewhere in the universe alive. Black holes exist in the real universe, however, white holes and wormholes are only theories and probably don't exist in the real universe.

Answer 4

Black holes have been theorized to exist for some time, and they have been confirmed by indirect (gravitational disruption) and direct (xray waves) observation. They require no "belief", they are very, very real.

Wormholes are purely theoretical. They are essentially an anomoly of Einstiens theories. No one has any idea where one might be found or how to create one. We DO know that they would be exceeedingly small and unstable, making any manipulation of them that would enable time travel dubious at best (to keep open a wormhole one meter in diamete would require as much energy as the sun outputs in a million years... every second, anything trying to pass thorugh would have to somehow get through all that energy).

White holes are not backed by any serious science, they are purely speculation by those who are not well versed in astrophysics; they have no theoritical basis, and there is no proposed mechanism to support thier existance. These are purely a figment of the imagination at the moment; a wild dream that has no basis on reality. Someday, yes, we MAY discover them, but we also may discover that we are really the daydream of an eleven-legged centipede in the fifteenth dimension. It's not worth our time to even consider it.

Answer 5

Black holes have been proven to exist, so yes I do "believe" in them. White holes and worm holes are still on the murky edges of theoritcal science, and I wouldn't be too fast in giving judgment over either one. I do believe that we can and probably will be surprised, just as we have been many times before. Black holes themselves were a subject of science fiction, and now they're as real as you an me. Who knows? Maybe the next big discovery will be finding a white hole.

Time travel-wise, I wouldn't hold my breath, and I advise you to do the same. Even if we even find a worm hole connecting a black hole to a white hole, and we actually discover that time travel would be possibly through the worm hole, we would likely be centuries from developing the technology to do so.

Sorry, I'm so pessimistic... c'est la vie.

Answer 6

I believe in nothing that I have not see myself, but I do think that it is probable. They say a black holes gravity is so powerful that it warps time. They call this the event horizon. What if the things that are pulled into the black hole are sent to a time before the black hold or the start that collapsed even existed. No wouldn't that be a kick in the pants.

Answer 7

A black hole is a concept that has been proved but not entirely explored. For instance, we know of a black hole that really does exist in space, as we have seen it through telescopes. A white hole wouldn't be an entirely different concept, but it would employ the opposite of gravitational pull, something that some scientists won't believe unless they see it.

Answer 8

White holes may be just stars, think about it. Also black holes have ejecti that shots out of the top and buttom so I think that is how they remain stable. Finally I do no think thier is an anti-matter white hole or exit plane for the consumed materials.

Answer 9

If Einstein was right, black holes must theoretically exist. We think we have "seen" them using the Hubble telescope. I buy it.

I think a wormhole is Star Trek fiction.

Never thought about white holes.

Answer 10

Thats is a REALLY good question. I believe in Black Holes but the other ones seem reasonable as well.
