**Time Travel**

**The eminent physicist Prof Amos Ori, of the Technion-Israel Institute of Technology, has set out a theoretical model of a time machine which would allow people to travel back in time to explore the past. The way the machine would work rests on Einstein’s theory of general relativity, a theory of gravity that shows how time can be warped by the gravitational pull of objects. Bend time enough and you can create a loop and the possibility of temporal travel. Prof Ori’s theory, set out in the prestigious science journal Physical Review, rests on a set of mathematical equations describing hypothetical conditions that, if established, could lead to the formation of a time machine, technically known as “closed time-like curves.” In the blends of space and time, or spacetime, in his equations, time would be able to curve back on itself, so that a person travelling around the loop might be able to go further back in time with each lap.**
