**Mathematically, time travel is possible. Scientists have created a new mathematical model that dictates how time travel is theoretically possible. Experts used Einstein’s Theory of General relativity as basis for a hypothetical device which they named a Traversable Acausal Retrograde Domain in Space-time (TARDIS).**

In other words, they’ve come up with a mathematical model of a theoretical time machine box that has the ability to move back and forth through space and time.

For centuries have humans imagined traveling in time. This idea resulted in countless movies, series and books produced and science fiction seems to have figured out everything there is about Time Travel. But now scientists decided to see whether they could learn something more about time travel and whether this is just an idea possible in science fiction.

“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,” said Ben Tippett, a physicist and mathematician from the **University of British Columbia**, **said in a UBC news release**, adding “But, mathematically, it is possible.”

What Tippett and his colleague from University of Maryland astrophysicist David Tsang created was a mathematical formula based on Einstein’s General Relativity theory to show how Time Travel is in fact possible, at least in theory.

**According to the abstract of the scientific paper,** which was **published in the journal Classical and Quantum Gravity**, “we present geometry which has been designed to fit a layperson’s description of a ‘time machine.’ It is a theoretical box which allows those within it to travel back and forth through time and space, as seen by an external observer.”

Graciously, they’ve named it TARDIS—which stands for Traversable Acausal Retrograde Domain in Space-time.

Tippet further explained how: “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.”

In other words, their newly formulated model ‘assumes’ how time could curve around high-mass objects just as physical space does in the universe.

Tippet and Tsang refer to their TARDIS as a space-time geometry “bubble” that has the ability to move fast than the speed of light. They explain in their paper how: “It is a box which travels ‘forwards’ and then ‘backwards’ in time along a circular path through space-time.”

“Delighted external observers would be able to watch the time travelers within the box evolving backward in time: un-breaking eggs and separating cream from their coffee,” explain scientists in their paper.

But don’t get all excited, it’s still not possible to build—at least not yet.

“While is it mathematically possible, it is not yet possible to construct 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**.

The research was published in *Classical and Quantum Gravity.*
