The MATH of time travel REVEALED: Scientists says we CAN travel in time

A recent study suggests that time travel is, mathematically speaking, possible.  An eminent researcher has found that space shouldn’t be broken into three dimensions where time is seen separately.  Alternatively, four dimensions should be imagined as a whole (space-time continuum), in which the different directions are closely related.

Although time travel has been achievable in books and movies only, a scientist has found that it is possible in reality, too.

A researcher has come up with a new, revolutionary model that reveals—mathematically—time travel is in fact attainable. Even though it seems to work mathematically, scientists have yet to find the ‘right’ materials to create a fully functioning ‘time machine’.

The study was published in the IOPscience Journal Classical and Quantum Gravity and suggests that mathematically speaking we can travel in time:

“In this paper, we present geometry which has been designed to fit a layperson’s description of a ‘time machine’. It is a box which allows those within it to travel backwards and forwards through time and space, as interpreted by an external observer. Timelike observers travel within the interior of a ‘bubble’ of geometry which moves along a circular, acausal trajectory through spacetime. If certain timelike observers inside the bubble maintain a persistent acceleration, their worldlines will close.

Our analysis includes a description of the causal structure of our spacetime, as well as a discussion of its physicality. The inclusion of such a bubble in a spacetime will render the background spacetime non-orientable, generating additional consistency constraints for formulations of the initial value problem. The spacetime geometry is geodesically incomplete, contains naked singularities, and requires exotic matter. “

Ben Tippet, an eminent mathematics and physics instructor at the University of British Columbia`s Okanagan campus is the one who claims that time travel is possible, at least mathematically speaking.

“People think of time travel as something of fiction, and we tend to think it’s not possible because we don’t actually do it. But mathematically, it is possible,” he said.

The researchers used Einstein’s theory as expertise and noted that the curvature of space-time is accountable for the curved orbits of the planets.  As Tippet explains, if it wasn’t curved, the planets would travel in a straight line.

Stop for a second and imagine yourself standing next to a huge start. Space-time geometry becomes curved, which makes all the cosmic bodies to literally bend.

“The time direction of the space-time surface also shows curvature. There is evidence showing the closer to a black hole we get, time moves slower,” says Tippett. “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.”

For the aim of the study, Tippet created a mathematical model called Traversable Acausal Retrograde Domain in Space-time, also called TARDIS.  As he describes it, it is a bubble of space-time geometry which is capable of carrying contents back and forth through space. It travels in space-time at a speed greater than the speed of light times 8, which allows it to move backward in time.

“Studying space-time is both fascinating and problematic. And it’s also a fun way to use math and physics,” says Tippett. “Experts in my field have been exploring the possibility of mathematical time machines since 1949. And my research presents a new method for doing it.”

However, although it is mathematically attainable, it is not yet possible to build such a machine as the researchers need materials, known as exotic matter, to bend the space-time in otherwise impossible ways.
