What are black holes in space?

No one has ever seen a black hole and it is unlikely that anyone ever will. They exist only as complex scientific calculations. But evidence obtained from studying the universe suggests that they are out there somewhere.

The principle behind a black hole is that it is an object with a force of gravity so strong that nothing can escape from it not even light! This is not too easy to imagine. But space scientists reckon that anything falling into a black hole would never be seen again – pretty spooky. Their thinking goes that black holes are formed when massive stars, much bigger than even our sun, reach the end of their lives and shrink. As they shrink they squeeze everything inside to an infinite density.

The major clue to the existence of black holes is X-rays which have been detected by satellites outside the earth’s atmosphere. These seem to come from gas falling into black holes. The gas gets so hot that it gives off X-rays which help pin-point where black holes might be.
