In BriefPhysicists have developed a new mathematical model that showshow time travel is theoretically possible. They used Einstein'sTheory of General Relativity as a springboard for theirhypothetical device, which they call a Traversable AcausalRetrograde Domain in Space-time (TARDIS). Bending Time <\/p>\n
Even before Einstein theorized that time is relative and flexible, humanity had already been imagining the possibility of time travel. In fact, science fiction is filled withtime travelers. Some use metahuman abilities to do so, but most rely on a device generally known as a time machine. Now, two physicists think that its time to bring the time machine into the real world sort of. <\/p>\n
People think of time travel as something as fiction. And we tend to think its not possible because we dont actually do it,Ben Tippett, a theoretical physicist and mathematician from the University of British Columbia, said in a UBC news release. But, mathematically, it is possible. <\/p>\n
Essentially, what Tippet and University of Maryland astrophysicist David Tsang developed is a mathematical formula that uses Einsteins General Relativity theory to prove that time travel is possible, in theory. That is, time travel fitting a laypersons understanding of the concept as moving backwards and forwards through time and space, as interpreted by an external observer, according to the abstract of their paper, which ispublished in the journal Classical and Quantum Gravity. <\/p>\n
Oh, and theyre calling it a TARDIS yes, Doctor Who fans, hurray! which stands for a Traversable Acausal Retrograde Domain in Space-time. <\/p>\n
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, Tippet explained. That circle takes us back in time. Simply put, their model assumes that time could curve around high-mass objects in the same way that physical space does in the universe. <\/p>\n
For Tippet and Tsang, a TARDIS is a space-time geometry bubble that travels faster than the speed of light. It is a box which travels forwards and then backwards in time along a circular path through spacetime, they wrote in their paper. <\/p>\n
Unfortunately,its still not possible to construct such a time machine. 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, Tippet explained. <\/p>\n
Indeed, their work isnt the first to suggest that time traveling can be done. Various other experiments, including those that rely on photon stimulation, suggest that time travel is feasible. Another theory explores the potential particles of time. <\/p>\n
However, some think that a time machine wouldnt be feasible because time traveling itself isnt possible. One points to the intimate connection between time and energyas the reason time travelingis improbable. Another suggests that time travel isnt going to work because theres no future to travel to yet. <\/p>\n
Whatever the case may be, theres one thing that these researchers all agree on. As Tippet put it, Studying space-time is both fascinating and problematic. <\/p>\n
