Using black holes to get from one place to another is an interesting story. Here, people sometimes talk about wormholes. Wormholes, or "shortcuts" through spacetime, were first considered because they arise as solutions to some of the equations of Einstein's general theory of relativity. Unfortunately, the first such solutions were such that if you tried to travel through one of them, it would immediately collapse and crush you (that is, having you in it would prevent the wormhole solution from working). In the mid 1980s, interest in wormholes that could be traversed was rekindled because Carl Sagan wrote a novel ("Contact"; perhaps you've seen the movie?) in which he needed a wormhole that could be traveled safely. Given that he was a famous scientist, he didn't want to just babble meaningless technojargon, so he called up his friend Kip Thorne, a professor at Caltech who is an expert in general relativity. Thorne and his colleagues have since worked out some solutions of the equations which *may* allow for wormholes that can be traveled through safely. The only catch is that they have to be made of so-called "exotic" matter, which has a total energy which is negative. This isn't quite as impossible as it sounds, but it still isn't all that likely!
By the way, one tricky thing about wormholes, and about faster-than-light travel in general, is that any time you can appear to go faster than light, you can travel backwards in time (this is one consequence of Einstein's theory of relativity). Therefore, if you have a wormhole you can time-travel. This can lead to lots of nasty paradoxes: one of the most common is called the grandfather paradox. In this paradox, we suppose that I am a brilliant scientist but a real scumbag of a person. I invent a time machine, and my use for it is to go back in time and kill my grandfather before he met my grandmother. Since he's dead, he can't produce my father, who can't produce me, which means that I could not have built the time machine and killed my grandfather, which means that he was able to meet my grandmother and produce my father, then me, so I was able to make the time machine and kill him, so... you get the picture! Paradoxes like this convince some people that you can't travel in time, so you can't travel faster than the speed of light, but it isn't as clear-cut as it seems.

∙ 13y agono, a black hole is just to massive and pulls its self into an infinitely small point.

Is a black hole hot?
I will try to simplify the answer down to the black hole object itself, and I assume the question revolves around classic black holes and not quantum black holes (which may very well be the hottest hypothetical objects in the universe).It is insufficient to state that a black hole is simply "cold" or "hot", since black holes can be both - and only in extremes.A black hole attracts matter via. the immense gravitational pull, and as with anything to which motion is applied, heat is generated. While a black hole attracts matter the temperature will therefore bevery high, as the absorbed matter will reach incredible speeds while it enters the black hole, and the outer layer will reachenormous temperatures. In other words, the compression of the matter itself heats up the outer layer of the black hole to millions of degrees.It is a widespread misunderstanding that black holes do not emit radiation. While black holes are consuming matter,radiation, such as x-ray and gamma ray, will be emitted from the black hole. And this is in fact how we typically detect a black hole. You should also be able to observe the actual heat, as black holes will not be absolutely black while they are absorbing matter, and can potentially light up the surrounding objects.The biggest black holes however, may be the coldest objects in the universe, given there is no matter around them left to consume. This means that they will either emit little or no radiation at all, and the temperature will be only near a billionth of a degree above absolute zero.
Do rhinos and elephant live near each other?
Yes. African elephants and black rhinos share much of the same territory, and can often be found drinking at the same watering holes.
Do badges dig holes?
other than shovels, most inanimate objects cannot dig holes. So no
If something ges sucked into a black hole will it come out of the other end?
The current theory by Stephen Hawking is that black holes slowly "evaporate" over time; so if you are sucked into a black hole you are crushed to microscopic size and held in the black hole; and then billions of years later the elemental particles elements that were you are released back into space to be re-used for something else.
Why the boat was in the middle of lake bed in holes?
To get to the other side
How is gravity related to black holes?
it is said that there are black holes in space which we have discovered is true and how gravity realates to a black hole is well, a black hole is said to suck away other universes we have not discovered yet gravity pulls things to the ground and a black hole uses that same pull force to suck in universes
Is there other universes inside blackholes?
That is a theory. That black holes may warp space and time, to fit an an entire universe inside it.
Is it possible the big bang wasn't a bang at all but a white hole from another universe?
There is no scientific evidence that White Holes are possible or that there are other universes. While it may pass in Science Fiction it is not science. Scientists say it is very possible that there parallel universes and that a white hole is the opposite of a black hole also. Science may be stranger than science fiction.
What is at the end of a black hole on the outside?
If you mean the 'other side' of a black hole, we don't really know. The other end of a black hole could be a rabbit hole, spitting matter into a parallel universe. Or perhaps there is no other side and matter is simply gone. Many believe it is possible that black holes could be gates into other universes or parallel worlds. However, since we haven't thrown anyone into black holes, we don't know what lies on the other side.
Are there wormholes in the universe?
Wormholes, aka "Einstein-Rosen bridges," were once thought to connect quasars and black holes. It is now known that quasars ARE black holes, and there is no evidence they are connected to anything. Black holes are pinched off spaces of our universe, exotic and strange, but not mystically mysterious. It remains theoretically possible we could manufacture connections to other points in space-time or other dimensions (universes) through "wormholes," or something like them, however what is possible is sometimes also unlikely. Wormholes are not particularly likely.
Is the universe made of black holes?
No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.
Is it possible that there are parallel universes which form the multiverse?
It is entirely possible, but difficult to verify, one way or the other.
Did other universes start with a big bang like ours?
That is unknown. Some hypotheses based largely in mathematics have suggested that this is possible, but there is no direct eveidence that other universes exist.
Do black holes come near each other?
We aren't certain, because 99.9% of what we THINK we know about black holes is theoretical. But the theory says that if two black holes do come too close to each other, they will merge to form one larger one. However, if the geometry of their approach is right, it might be possible for them to orbit each other.
Is there a possibility that wormholes and black holes are gateways to other dimensions in this universe?
Yes, it's possible but we really just don't know.
Is it possible for 2 black holes to collide with each other?
Yes and they would get bigger and gain more mass. So the basically combine into a bigger black hole
Is there another Universe in a different dimension?
Some theories allow for the possibility that other universes (some of which might have a different number of dimensions than our own) could exist, though it's generally believed that there is no possible way to actually observe these other universes.
