But Ori puts forth a different approach eliminating the need for exotic matter.

"If the proper initial conditions were achieved, the time machine would evolve on its own without any further intervention," he asserts. "It can be likened to shooting a ship with a cannon. Once the cannon is aimed properly and fired, the cannonball hits the ship on its own, driven solely by the laws of physics. The machine is space time itself. 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."
