Check it out!!!
Einstein's general theory of relativity explains how matter {a black hole which has a large gravitational Field} creates gravitational force by distorting the fabric of space and time. He found that matter has an effect on space and the rate time passes. This might be what u are referring to as "time travel". Although, there is no travel with black holes just allot of gravity that slows time down. (that is, if u could get close without getting sucked in you would know the effects.)
What i think: the only way to know what is in a blackhole is to observe the exterior of one.
from the info we have nothing can exsist in a black hole, not even black, how can there be something where there is a distortion of light and time?

Black holes don't actually have anything to do with time travel, except in science fiction. Some people believe (Stephen Hawking being one apparently) that bh's could contain "worm holes" - areas in space which can transport something or someone to different parts of the universe in seconds. But it's purely hypothetical, there's no evidence to back this up with as yet.

At the very heart of a black hole is a singularity - a point in space where all laws of physics breakdown, therefore events become completely unpredictable. This singularity (which, incidentally is also the "thing" that went bang as in big) is infinitely small, too small to have any spatial dimensions, but also infinitely heavy, which causes the tremendous gravitational effect that it has.

And don't forget that, no matter how probable, bh's are still only theoretical and none have ever been directly observed. I'll probably get loads of thumbs-down for saying that but it's perfectly true.

One: Black Holes do not contain a live star, and therefore do not emit (produce) light. Since that is the case, they are dark, and normally invisible to us. The structure of Black Holes (this is theory) is such that they have enormous gravitational pull and absorb (retain) all light that comes into them. Since almost everything we see with our eyes is either light from an emitting source, or light from a source that is reflected off of some object, when trying to look for a black hole (not an emitter, and does not permit reflected light to escape) we see nothing - Invisibility.

Two: Black Holes have nothing to do with time travel. Science Fiction proposed the idea that they might be worm holes into a different segment of time. Cute idea, but not a working model.

Three: Time Travel is not possible. However, it does make for some exciting dreams and stories.

Scientists can tell that a black hole is a massive object by the gravitational pull on nearby bodies. It is 'black' because its gravity is so strong that light can not escape (a photon returns to the black hole like a baseball thrown up into the air on earth). The mass is concentrated at the center in a singularity and time is distorted within its event horizon. That has little to do with time travel (except perhaps to prove that time is not constant).

Nothing
As an infalling object approaches the singularity, tidal forces acting on it approach infinity. All components of the object, including atoms and subatomic particles, are torn away from each other before striking the singularity. At the singularity itself, effects are unknown; a theory of quantum gravity is needed to accurately describe events near it. Regardless, as soon as an object passes within the hole's event horizon, it is lost to the outside universe. An observer far from the hole simply sees the hole's mass, charge, and angular momentum change slightly, to reflect the addition of the new object's matter. After the event horizon all is unknown. Anything that passes this point cannot be retrieved to study.

A black hole is a region of space in which the gravitational field is so powerful that nothing can escape after having fallen past the event horizon. The name comes from the fact that even electromagnetic radiation (e.g. light) is unable to escape, rendering the interior invisible. However, black holes can be detected if they interact with matter outside the event horizon, for example by drawing in gas from an orbiting star.

Well, nothing really.... this things of warp holes or worm-holes, bending space and time so we can travel to the other side of the universe.... is a lot of BS that the scientist keep telling us to keep us occupied.
It is a fact that black holes do exist because gravity does exist.... but if we rely on them to travel.... lolololol we would be better off using public transport... we wouldn't be going anywhere if we are caught by the tentacles of a black hole.....

Beyond the event horizon,in the middle of the black hole,is what scientist known as 'white holes',at here there's no more gravity and as u slowly float along,there comes worm hole where u travel faster than light,or literally 'wrap' to another people say as another dimension.So,time travel does associate with black hole but it the condition is to survive the crushing G-force of the black hole..

Black holes and worm holes are two different things. Black holes have been proven to not have anything to do with time travel.

Inside a black hole is an extremely heavy, dense mass with a humongous gravity.
No physical body can get past the Roche limit of a black hole without having its atomic structure shredded to subatomic particles.
