WORMHOLES – tunnels through space-time that connect black holes – may be a consequence of the bizarre quantum property called entanglement. The redefinition would resolve a pressing paradox that you might be burned instead of crushed, should you fall into a black hole.
Knowing which hazard sign to erect outside a black hole isn't exactly an everyday problem. For theoretical physicists, though, it reveals an inconsistency between quantum mechanics and general relativity. Solving this conundrum might lead to the sought-after quantum theory of gravity.
Don't know what a blackhole is?
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.
