New Theoritical Model Eliminates Barriers To Time Travel

"The machine is space time itself," Professor Amos Ori explains. "If we were to create an area with a warp like this in space that would enable time lines to close on themselves, it might enable future generations to return to visit our time. We, however, could not return to previous ages because our predecessors did not create this infrastructure for us."

A Technion-Israel Institute of Technology physicist has developed a theoretical model of a time machine that could enable future generations to travel into the past. In his paper published in the July issue of Physical Review, noted time-travel theorist Professor Amos Ori provides practical solutions to a number of criteria long seen by other experts as obstacles to the realization of time travel.

Ori's theory is actually 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."

Previous theories addressing time travel are well grounded in Einstein's General Relativity theory. Renowned physicist Stephen Hawking has called time travel "an important subject for research," but has also proposed some of the strongest challenges to the concept. General Relativity states, among other things, that the gravitational pull of large objects such as planets can actually bend time and space. Time travel research is based on bending space-time so far that the time lines actually bend 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," says Ori. "We are trying to find out if it is possible to manipulate space-time to develop in such a way."
