World Exclusive video: Time Travel Scientist Dr. Ronald Mallett, History Channel
Posted by in Uncategorized on March 16, 2010
For quite some time, Ronald Mallett has been working on plans for a time machine. This machine uses a ring laser and the theory of relativity. Mallett first argued that the ring laser would produce a limited amount of frame-dragging which might be measured experimentally, saying: In Einstein’s general theory of relativity, both matter and energy can create a gravitational field. This means that the energy of a light beam can produce a gravitational field. My current research considers both the weak and strong gravitational fields produced by a single continuously circulating unidirectional beam of light. In the weak gravitational field of a unidirectional ring laser, it is predicted that a spinning neutral particle, when placed in the ring, is dragged around by the resulting gravitational field. In a later paper, he argued that at sufficient energies, the circulating laser might produce not just frame-dragging but also closed timelike curves, allowing time travel into the past: For the strong gravitational field of a circulating cylinder of light, I have found new exact solutions of the Einstein field equations for the exterior and interior gravitational fields of the light cylinder. The exterior gravitational field is shown to contain closed timelike lines. The presence of closed timelike lines indicates the possibility of time travel into the past. This creates the foundation for a time machine based on a circulating cylinder of light. Funding for his program, now known …
