Short Bytes: The University of British Columbia’s Ben Tippett has recently published a study that talks about the mathematical possibility of time travel. Using math and physics, he, along with University of Maryland’s David Tsang, has developed a formula that describes the method for time travel. He has named the model TARDIS, which is basically a space-time geometry bubble that travels at a speed faster than light.In 1885, H.G. Wells published his book Time Machine, which was a time traveler’s amazing firsthand account of the journey 800,000 years beyond his own era. Since then, the scientists have been working to satisfy the curiosities of people and trying to solve this problem. After Albert Einstein introduced the theory of general relativity, this issue became much hotter.
Science fiction and movies are filled with the time traveling incidents and their stories. But, when is it going to become reality in real life? Well, two physicists think that devising such machine is possible.
Ben Tippett, a theoretical physicist from the University of British Columbia, says that time travel is mathematically possible. “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,” he says.
Tippet and University of Maryland’s David Tsang developed a mathematical formula that makes use of Einstein’s General Theory of Relativity to prove the theoretical possibility of time travel.
Tippet explains that his time machine model uses the curved space-time to bend time into a circle for the travelers. The model assumes that time could curve around high-mass objects and the circle could take us back in time.
Wondering what’s the name of this proposed time machine model? It’s called TARDIS — Traversable Acausal Retrograde Domain in Space-time.
Tippet calls TARDIS a space-time geometry bubble that travels at a speed faster than light. So, in a circle, the box travels forward and backward in time on this circular path.
But, is it possible to make this time machine in reality? At the moment, the construction of TARDIS isn’t possible because we don’t have such a material, also called exotic matter, that can bend space-time in special ways.
“Studying space-time is both fascinating and problematic. And it’s also a fun way to use math and physics,” says Tippett. “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.”
His research was published in IOPScience Classical and Quantum Gravity journal.
