what`s into a black hole....is there anything on the other side...or is it just a body with big gravity?

Question

....why is it black

Answer 1

The edge of a Black Hole is called the Event Horizon.

Anything that passes that close will be pulled in. Even light. Since light can't reflect off it, it would appear black. Once something gets that close, it is sucked into the center and crushed into the singularity at the center.

The singularity inside contains all the matter of a large star.. but it's crushed impossibly small. Infinitly small, infact.

Some speculate that there are things called 'White Holes' from which comes matter consumed by it's partner Black Hole in another part of the Universe. I concider this highly unlikely and speculative, at best.

It has been proposed it may be possible to connect black holes to eachother, creating a hyper-dimentional tunnel through space/time or a wormhole. I find this more likely, but still questionable.

Answer 2

A black hole is an object predicted by general relativity with a gravitational field so strong that nothing can escape it — not even light.

A black hole is defined to be a region of space-time where escape to the outside universe is impossible. The boundary of this region is a surface called the event horizon. This surface is not a physically tangible one, but merely a figurative concept of an imaginary boundary. Nothing can move from inside the event horizon to the outside, even briefly.

Theoretically, a black hole can be any size. Astrophysicists expect to find black holes with masses ranging between roughly the mass of the Sun ("stellar-mass" black holes) to many millions of times the mass of the Sun (supermassive black holes).

The existence of black holes in the universe is well supported by astronomical observation, particularly from studying X-ray emission from X-ray binaries and active galactic nuclei. It has also been hypothesized that black holes radiate energy due to quantum mechanical effects known as Hawking radiation.

The concept of a Black Hole is complex, and can be counter-intuitive.

Matter as we know it, exists because forces such as the electromagnetic force and others keep the subatomic particles apart. As the particles get closer this force very strongly keeps them apart, otherwise they would be pulled together by gravity. But if there is enough matter in a small enough space, gravity ends up winning, and the matter collapses - electrons cannot stay distant from the atomic nucleus, and so incredibly dense matter forms, and then even this cannot maintain its structure and collapses into itself further. In a way that is hard for people to imagine, nothing can stop this collapse if enough matter gets into a small enough space, and the matter collapses literally to a point. Not a pinhead size, or any size, but a literal point, zero wide, zero high, zero deep. We cannot imagine such a thing, but physics says that is what happens, and that is a black hole, matter that is so dense it is no longer "matter" in any real sense, but some kind of singularity (or anomaly) in space. Anything that gets too close will also collapse with it the same way, whether matter or energy, even light itself, the fastest thing in the universe. This is how it acquires the name "black hole".

To the surprise of physicists, it was later found that energy can escape from black holes in an unexpected way, and that therefore black holes "evaporate". In space, virtual particles are continually coming into existence and vanishing on a microscopic scale so small they cannot easily be detected. This is a consequence of quantum physics and only works on a tiny (subatomic) scale. Conceptually and in simple terms, these particles can be imagined to appear in pairs and vanish a tiny fraction of a second later again. For this reason they are not readily noticed. But near the very edge of a black hole, the event horizon, even in that fraction of a second, the intense gravitational field separates the two particles. One may be absorbed into the black hole, the other escapes. From an external perspective all that is seen is the second of these, giving the appearance of energy being created. In fact this is energy that escapes from the black hole, from its gravitational field beyond the event horizon. In this way paradoxically a black hole can "evaporate".

Answer 3

There is nothing on the other side. Perhaps you are thinking of a worm hole.

A black hole is a star that has imploded. The mass of the star is reduced to such a small area that it has a tremendous amount of gravity pull. If another body gets even close to the black hole, it gets sucked into it.

Answer 4

in basic terms as this is now, interior the very early universe it became area itself that became increasing. the growth of area isn't constrained by ability of the fee of sunshine, like be counted is. the fee of sunshine governs how quickly be counted can conflict through area, even though it has no touching on how quickly area itself can enhance. What the strain of gravity is strictly, and whilst it began out to impression the form of the early universe is unknown. Even now area seems to be increasing swifter than the fee of sunshine. interior the early universe the growth of area itself became positively sufficient to triumph over in spite of the fact that forces would have been working against it. The uniform dispersal of "be counted" and "power" interior the early universe could have prevented the formation of black holes, as there became no person specific element that would have had an better impression than the different, and gravity became no longer sufficient to triumph over the speedy growth of the universe. in some unspecified time interior the destiny a loss of symmetry interior the dispersal of be counted interior the early universe allowed gravity to drag mutually the thinly dispersed be counted interior the universe into the celebs, galaxies, and black holes that all of us be attentive to right this moment.

Answer 5

Black holes are black because the gravity is so strong that photos cannot escape. Their mass is such that a black hole the sixe of a proton would have a mass of around 10,000 tons.

Answer 6

a black hole is a very dense body with several million kgs of mass packed in a small space like 1m3.
due to this it exerts a very strong gravitional force .
its gravity is so strong that even light can't escape it's gravitational feild so it is practically not visible to us and anything which is not visible to us is said to be black.
next, there is definately empty space on both sides as it is just a condensed mass of matter.

Answer 7

ive wondered this too. it seems to disregard all laws of physics, and is just nothingness, a giant hole that sucks things in and then destroys the matter. btw the theory that matter cannot be created or destroyed it the basis of our understanding of physics.
and it is black because it also destroys light, and nothing is inside.
there is a possibility that it is like a transporter and they end up on the ohter side of the universe, but teleporting also is against all understadning of physics

Answer 8

I agree with Radioacti...
It's black becuase it's gravity is so strong it pulls in light, so light can't bounce off it and back to the the human eye.

Answer 9

I beleive that it is actually less than nothing causing it bring in other matter like planets even though black holes ar no bigger than a pencil dot.

Answer 10

This is a very informative video documentary on black holes: http://www.pbs.org/wgbh/nova/blackhole/program.html
It explains everything you're looking for.
