sa akong pagka sabot sa theory of relativity is you can bend space if you have a very large mass on it.. the problem is, even black holes dont allow two spaces to connect with each other (wormholes)... no such mass exists or discovered to date.
the most probable explaination of a wormhole is to travel from one side of a black hole ACROSS to another point.. that would save you a lot of time than by just going around.. but you have to deal with the intense gravity...
