Scientist finds the formula for time travel, names it TARDIS
A scientist from the University of British Columbia in Canada calculated how we can time travel. All we have to do is bend space.
“People think of time travel as something fictional,” math and physics instructor Ben Tippett. “And we tend to think it’s not possible because we don’t actually do it. But, mathematically, it is possible.”
The scientist started from Einstein’s theory of general relativity. More specifically, from the fact that giant cosmic objects, such as black holes, can distort the space-time continuum.

“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,” Tippett explained.
Although this is mathematically feasible, it is extremely hard to obtain in real life as we don’t have the materials required for the construction of such a “time machine”. Physicists call it “exotic matter”.
Also, Tippett’s space-time bubble should move at speeds surpassing the speed of light in order to travel through time. Einstein’s relativity theory mentions that there are no speeds greater than the speed of light because an object would need infinite energy to accelerate at that level.
On the other hand, quantum mechanics introduced on a theoretical level the tachyons, particles which move at speeds faster than light. If such particles exist, then time travel is possible.
Back to Tippett, he named his theory “Traversable Acausal Retrograde Domain in Space-time” or TARDIS, referring to the time travel cabin in popular TV show Doctor Who.

If we are to listen to Stephen Hawking, he previously stated that should time travel be possible, we won’t be able to use it because the Universe requires a mechanism for protecting the temporal line.
Scientists from Washington State University, though, recently created a fluid with negative mass. This brings hope that in the future we might produce the exotic matter need to build a time travel machine.
