According to the Jerusalem Post, an Israeli scientist is making progress toward the discovery of a way to travel back in time. Seriously. Sort of:
[Prof. Amos] Ori, 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. In a paper published in the latest issue of the Physical Review journal, the scientist offers a theoretical model, based on mathematical equations describing conditions that, if established, could help lead to the development of a time machine of sorts. But rather than building an actual device, Ori explains that “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.
“We know that bending does happen all the time, but we want the bending to be strong enough and to take a special form where the lines of time make closed loops,” explains Ori. “We are trying to find out if it is possible to manipulate space-time to develop in such a way.”
Considering going back and doing something that would drastically change the time-line (say, killing Hitler in 1932) would mean The End of the World As We Know It, I would opt for something a bit less radical. I’m thinking of going back to 1991 and telling Lonnie Smith to run flat out during the eighth inning of Game 7 of the World Series. It wouldn’t change world history, but it would make lots of Atlanta Braves fans very happy.
