Time travel has been a major feature of science fiction for a long period of time. Most of the times, characters in these fictional works rely on time machine and researchers have created a new model that shows that time travel can be possible in real world. Albeit, mathematically.
Talking about the time Ben Tippett, a theoretical physicist and mathematician from the University of British Columbia, said in a UBC news release, “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.”
Tippet and University of Maryland astrophysicist David Tsang developed a mathematical formula that uses the theory of general relativity to show that time travel is indeed possible. The model assumes that time could curve around high mass objects. Tippet explained, “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.”
According to the model, the time machine is a space-tome geometry bubble that travels faster than light by embracing a circular path through spacetime. However, Tippet was quick to point out that such machine isn’t feasible at present. He wrote, “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.”
This isn’t the first time such models or ideas have been presented to consider. For example, one model in the past examined the possibility of time travelling through photon stimulation. While such methods hold themselves true mathematically, a number of people thing that a time machine isn’t possible as there is a connection between time and energy. Despite that, as time travelling is an intriguing question, it’s far from the last time we hear something like this.
