How black holes are made. Anything can turn into a black hole as long as it is small. the earth as the size of a peanut would be a black hole. Mountains smaller then a centimeter would be a black hole.
A black hole can pull so much gravity that lite can't excape. If you went into a black hole feet first you would be stress so long that you would die. A black hole can alsow be crated by stars being destrod whenever a star explods the core of the star comepresis into a black hole.
What well it look like if I were watching you go into a black hole. It wouldn't look like you rushing into the black hole it would look like you were fading and getting red. Why would you become red becaus at the same time you are getting vilintley stressed apart entel you pop.
