“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. 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.
Unfortunately, it’s 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.
Indeed, their work isn’t 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. However, some think that a time machine wouldn’t be feasible because time traveling itself isn’t possible. One points to the intimate connection between time and energy as the reason time traveling is improbable. Another suggests that time travel isn’t going to work because there’s no future to travel to yet.

ReplyDelete'Unfortunately'??? I think it is bloody fortunate :-p
