What Happens To Time In A Black Hole?

No-one knows for sure. However, the massive gravitational forces created by a black hole bends light rays. It's therefore plausible that a black hole can do the same with time.

Black holes are collapsed suns which have imploded to a point of near zero volume and infinite density. If our own sun were to become a black hole, it would end up with a radius of around 10 km. As the escape velocity needed to break away from the gravitational force of a black hole is in excess of light speed nothing can break out of a black hole once it is sucked in, not matter, radiation or light.

Scary places, indeed. But some scientists have proposed that black holes may be the answer to space travel. They have postulated that if two black holes in different parts of space were to join up, a worm hole would be created. This worm hole would be a shortcut enabling massive distances to be travelled in space time. Whether anything could survive such a hypothetical journey is unknown. And whether a space ship could make the return journey and arrive back in the same time and place is another mystery.
