The World First Time Machine (4/5)

Playlist: www.youtube.com A TLC documentary exploring the possibilities of time travel Ronald L. Mallett is a full professor of physics at the University of Connecticut. For quite some time, Ronald Mallett has been working on plans for a time machine. This technology would be based upon a ring laser’s properties within the context of Einstein’s 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, he has 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 …
