What is a black hole?
A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
Because no light can get out, people can’t see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars.
Black holes are more common than we may think. There’s even one in our galaxy close enough for scientists to actually observe its destructive nature!
Even if NASA observed ‘a large flare’ coming out of a black hole, and Stephen Hawking says Black Holes are passage to another universe, I still wouldn’t risk to get swallowed by one!
