The reason for all this confusion and excitement is that Einstein's equations allow many kinds of time machines. (Whether they will survive the challenges from the quantum theory, however, is still in doubt) In Einstein's theory in fact, we often encounter something called“closed time-like curves”, which is the technical term for paths that allow for time travel into the past. If we followed the path of a closed time- like curve, we would set out on a journey and return before we left.
A possible time machine involves a wormhole. There are many solutions to Einstein's equations that connect two distant points in space. But since space and time are intimately intertwined in Einstein's theory, this same wormhole can also connect two points in time. Theoretically, by falling down the wormhole, you could journey into the past. But passing ( イ ) the wormhole at the center of a black hole is a one-way trip. As physicist Richard Gott has said, “I don't think there's any question that a person could travel back in time while in a black hole. The question is whether he could ever emerge to brag about lt.”
