Summary

Black holes are created when a giant star explodes into a supernova. The gravity of a black hole is so incredibly strong that it pulls in anything that gets close – even light! But what’s it like inside a black hole? Is it hot or cold? We asked astrophysicist Ian Hall to help us find the answer.

Got a question that’s a hole lot of fun? Send it to us at BrainsOn.org/contact, and we’ll help find an answer that really draws you in!
