Theoretical physicist Stephen Hawking, researcher of space, black holes and quantum gravity, is going to solve the main paradox of the universe. He states that objects absorbed by black holes do not disappear forever, but turn up in another place, possibly, in another universe.
In one of his works Hawking tells that black holes can be doors to alternative universes.
Black holes rotate, that’s why it is possible that they have passages to other worlds. But you cannot come back to the point where you started.
