Time Machine Part 1

If we can control gravity with a device, then we can actually control time, as well, and that could lead to a machine,” he said. The force of gravity is actually the bending of empty space, and the energy of light can create gravity, therefore light can potentially manipulate time, he explained.

Mallett’s idea for a machine involves using a circulating light beam with a series of mirrors, that can twist empty space. According to Einstein, if you bend space, then you bend time. “If I twist space, I can twist the line of time into a loop,” connecting the past to the future, he said. When a person travels back to the past, they will have altered the past, so the future may not play out in the way the way it originally did. This is known as the ‘Butterfly Effect’ where some little thing leads to a chain of reactions that alters the future, he detailed.

A time machine could only travel as far back as when the machine was first turned on. So for instance, if a machine was invented this year, time travelers from 2030 could only travel as far back as 2011, he continued. One of the more practical and important uses for time travel would be to send information back in time, rather than a person– like an early warning device for earthquakes or tsunamis that could save the lives of thousands of people, Mallett noted. He also touched on the time travel work of other scientists including Kip Thorne, who looks at using wormholes to create a path to the past, and Richard Gott, who theorizes about ‘cosmic strings.


The Idea Of The 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 as The Space-time Twisting by Light (STL) project, is progressing. Full details on the project, Mallett’s theories, a list of upcoming public lectures and links to popular articles on his work can be found at the professor’s UConn web page, and an illustration showing the concept on which Mallett has designed the time machine can be seen on a Geocities webpage.
