Space time question. Before I ask my question I suppose I should ask a preliminary quesiton that will tell me if my actual question has an answer. Does space time only exist in space? If so, is earths surface considered space, thereby abiding by space times rules? Also, theoretically if we were to bend space time we could travel 'through' space to get to another point. Now does this also relate to smaller scales such as if I was in space could I bend space time to allow me to travel say 50 feet away?
