Could We Return To The Past To Check On Those MARTIAN CLOUDEATERS? Physicists Say All We Need Is A “Cunning Idea” To Make TIME TRAVEL A Scientific Reality
In Einstein’s theory, time and space are mixed together: we cannot think of them separately. It therefore makes best sense to think of myself as always moving along that 4D world-line, travelling into the future at the speed of light. But is it possible to cheat the safeguards of Einstein’s theory and to travel backwards through time? At face value the answer is no, but then again, the science of earlier generations would have said it was impossible for mankind to fly. Perhaps all scientists need is inspiration and a cunning idea.
