      Hello,

      We don’t know what to find at the bottom – in fact we don’t think black holes can even have a bottom, or a top! Nothing can get out of a black hole because the gravity is too strong so if we sent a probe in there, it would never come out again! Here are two of my favourite youtube videos about black holes, check them out if you get a chance:

      We really don’t know, but black holes might even be gateways to other places, like in the movie interstellar!

      No one knows because nothing has ever come out of a black hole. Once something goes in it cannot come out so we will never be able to send something or someone in and for them to be able to tell us!

      Here’s another cool video about black holes from the Khan Academy (it’s a great place to go for lots of science questions): https://www.khanacademy.org/science/cosmology-and-astronomy/stellar-life-topic/stellar-life-death-tutorial/v/black-holes
