Researcher Reveals 'Bubble of Spacetime' --"A 'Time Machine' That Moves Greater Than Speed of Light Allowing It to Travel Back and Forward in Time"

After crunching some serious number and working on equations, a University of British Columbia researcher has developed a mathematical model for a practical time machine --a bubble of space-time geometry which transports its contents backward and forwards through space and time as it circuits a large circular path. The bubble travels through space-time at speeds faster than the speed of light at times, permitting it to move backward in time.

Ben Tippett, a mathematics and physics professor, whose area of expertise is Einstein's theory of general relativity, works on black holes and science fiction when he's not teaching. With the help of math and physics, he has generated a formula that defines a technique for time travel.

Ben Tippett says "People think of time travel as something as fiction. And we tend to think it's not possible because we don't actually do it. But, mathematically, it is possible."

Since HG Wells first popularized the idea in 1885, time travel has remained a steady theme in science fiction. But in reality, it might be more feasible than you’d think. 

In 1915 Albert Einstein publicized his theory of general relativity, declaring that gravitational fields are produced by bends in the fabric of space and time. More than a century later, the LIGO Scientific Collaboration--an international group of physics institutes and research groups-- declared the detection of gravitational waves produced by colliding black holes billions of lightyears away, confirming Einstein's theory.

The partition of space into three dimensions, with time in a distinct dimension by itself, is inappropriate, says Tippett. The four dimensions must be abstracted concurrently, where different directions are linked, as a space-time continuum. With the help of Einstein's theory, Tippett says that the curvature of space-time accounts for the curved orbits of the planets.

In "flat" -- or uncurved -- space-time, planets and stars would travel in straight lines. In the neighborhood of a massive star, space-time geometry turn into curved and the straight courses of neighboring planets will follow the warp and bend around star.

Tippett says: "The time direction of the space-time surface also shows curvature. There is evidence showing the closer to a black hole we get, time moves slower. My model of a time machine uses the curved space-time -- to bend time into a circle for the passengers, not in a straight line. That circle takes us back in time."

It is likely to define this kind of time travel by means of a mathematical equation, but it will surely take time.

He says "HG Wells popularized the term 'time machine' and he left people with the thought that an explorer would need a 'machine or special box' to actually accomplish time travel. While is it mathematically feasible, it is not yet possible to build a space-time machine because we need materials--which we call exotic matter--to bend space-time in these impossible ways, but they have yet to be discovered."

For his study, Tippett formed a mathematical model of a Traversable Acausal Retrograde Domain in Space-time(TARDIS).

Tippett says "Studying space-time is both fascinating and problematic. And it's also a fun way to use math and physics. Experts in my field have been exploring the possibility of mathematical time machines since 1949. And my research presents a new method for doing it."
