Some use metahuman abilities to do so, but most rely on a device generally known as a time machine.<\/p>\n<p>Now, two physicists think that it\u2019s time to\u00a0bring the time machine into the real world\u00a0\u2014 sort of.<\/p>\n<p>\u201cPeople think of time travel as something as fiction. And we tend to think it\u2019s not possible because we don\u2019t actually do it,\u201d\u00a0Ben Tippett, a theoretical physicist and mathematician from the\u00a0University of British Columbia,\u00a0said in a UBC news release. \u201cBut, mathematically, it is possible.\u201d<\/p>\n<p>Essentially, what Tippet and\u00a0University of Maryland\u00a0astrophysicist David Tsang<\/p>\n<p>developed is a mathematical formula that uses\u00a0Einstein\u2019s General Relativity theory\u00a0to prove that time travel is possible, in theory. That is, time travel fitting a layperson\u2019s<\/p>\n<p>understanding of the concept as moving \u201cbackwards and forwards through time and space, as interpreted by an external observer,\u201d according to the abstract of their paper, which is\u00a0published in the journal\u00a0Classical and Quantum Gravity.<\/p>\n<p>Oh, and they\u2019re calling it a TARDIS \u2014 yes, \u201cDoctor Who\u201d fans, hurray! \u2014 which stands for a Traversable Acausal Retrograde Domain in\u00a0Space-time.<\/p>\n<h2><b><strong><u>Feasible but Not Possible. Yet.<\/u><\/strong><\/b>\u00a0\u00a0\u201cMy model of a time machine uses the curved space-time to bend time into a circle for the passengers, not in a straight line,\u201d Tippet explained. \u201cThat circle takes us back in time.\u201d<\/h2>\n<p>Simply put, their model assumes that time could curve around high-mass objects in the<\/p>\n<p>same way that physical space does in the universe. For Tippet and Tsang, a TARDIS is a space-time geometry \u201cbubble\u201d that travels faster than the speed of light.\u00a0\u00a0\u00a0\u201cIt is a box which travels \u2018forwards\u2019 and then \u2018backwards\u2019 in time along a circular path through spacetime,\u201d they wrote in their paper.<\/p>\n<p>Unfortunately,\u00a0it\u2019s still not possible to construct such a time machine.\u00a0\u201cWhile is it mathematically feasible, it is not yet possible to build a space-time machine because we need materials \u2014\u00a0which we call exotic matter \u2014\u00a0to bend space-time in these impossible ways, but they have yet to be discovered,\u201d Tippet explained.<\/p>\n<p>Indeed, their work isn\u2019t the first to suggest that time traveling can be done. Various other experiments, including those that\u00a0rely on photon stimulation, suggest that\u00a0time travel is<\/p>\n<p>feasible. Another theory explores\u00a0the potential particles of time. However, some think that a time machine wouldn\u2019t be feasible because time traveling itself isn\u2019t possible. One<\/p>\n<p>points to\u00a0the intimate connection between time and energy\u00a0as the reason time traveling\u00a0is improbable. Another suggests that time travel isn\u2019t going to work because\u00a0there\u2019s no future to travel to yet.<\/p>\n<p>Whatever the case may be, there\u2019s one thing that these researchers all agree on. As Tippet put it, \u201cStudying space-time is both fascinating and problematic.\u201d<\/p>\n\n<div style=\"font-size: 0px; height: 0px; line-height: 0px; margin: 0; padding: 0; clear: both;\"><\/div>","protected":false},"excerpt":{"rendered":"<p>been imagining\u00a0the possibility of time travel.
