      Apparently, a black hole is an area of space which has become deformed due to a large mass, and from which nothing can escape – not even light! Of course, if light cannot escape, then it will look black!

      Are you interested in space?

      Hiya doodle! A black hole is a region in space or a body of matter which is so massive, no light can get out. They’re difficult to see because space is black and a black hole is, err… well… black.

      You can still see things on the outside. The light from the things on the outside can still reach you. No one on the outside can see you, of course, since the light from you can’t escape out so you can shout as loud as you want but no one will see you 🙁

      Technically a singularity in space and time; in reality it is what formed when a massive star (at least 10x mass of the sun) runs out of fuel (which removes the outward pressure) and it collapses under gravity to something that has such a large gravitational pull that even light cannot escape from it

      A star that has imploded (sort of the opposite of exploded!) creating an object of very high mass in a very small space, with a gravitational field that nothing can escape!
