Does anyone know where I might find a good beginners guide to black holes?
I know its a big topic to start from scratch - but I'm a quick learner.

A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape its grasp. It is created when a massive star dies and its core collapses under its own gravity.
Black holes can range in size from small, stellar-mass black holes to supermassive black holes that can have the mass of billions of suns. The size of a black hole depends on the amount of matter it has consumed and its location within a galaxy.
If you were to fall into a black hole, you would experience extreme tidal forces that would stretch and compress your body. As you approach the center, known as the singularity, the gravitational pull would become infinitely strong and you would be crushed to an infinitely small point.
According to current scientific understanding, nothing can escape from a black hole. However, recent theories suggest that some information may be able to escape in the form of Hawking radiation, but this has not been proven yet.
Black holes are only dangerous if you get too close to them. Their strong gravitational pull can disrupt the orbits of nearby objects and even pull them into the black hole. However, the chances of encountering a black hole in space are very slim, so there is no need to worry about their danger.
