Time is known as the fourth dimension of reality. It's relationship is symbiotic with space.
Travel to the future
Time passes faster when you are farther from a gravitational pull. When you travel around a blackhole enough you revel to the future as well.
In 1963, Roy Patrick Kerr was the first to propose the black hole. If a dying star collapsed in a ring of a neutron star this would prevent it from turning into a singularity. Blackholes without singularities are known as white holes and these are safe to enter. Whiteholes push everything out, however it is not known where they push everything to.
