A physicist from the Technion-Israel Institute of Technology in Haifa, has come up with what he says are practical solutions to overcome the hindrances that experts have long regarded as stopping us from traveling back in time. But rather than building an actual device, the machine is space-time itself. Time travel research is based on bending space-time so far that the time lines actually warp back on themselves to form a loop. While the possibility of time travel has never been ruled out, scientists have identified a number of physical challenges, such as not enough exotic matter, to create the necessary warp and get the wheels of time to turn back. However this new research path suggests that if the proper initial conditions were achieved, the time machine would evolve on its own without any further intervention.
