      A black hole is a huge amount of matter squished into a very, very, very small amount of space. For this to be possible, gravity inside it is very strong and it pulls everything in one tiny space and keeps it there. Anything that gets close to it gets pulled inside it. So far, what we know is that all the information, light, objects, people who will enter a blackhole wouldn’t be able to go to the entrance and go back home. It’s like a one-way ticket to a tiny, tiny space somewhere in the universe.

      Black holes are a part of space-time where gravity is so strong that nothing can escape, not even light. This happens because they are extremely massive, so they have a very strong gravitational pull. Black holes have something called the ‘event horizon’ which is basically the point at which the gravity becomes so strong that everything gets sucked inside. Then, at the centre, you can find the singularity which is (according to theory) where the curvature of space-time becomes infinite! Once something enters a black hole, it gets sucked towards the singularity.
