According to
a new study, time travel is—mathematically speaking—possible. A researcher has
concluded that space should NOT be divided into three dimensions—where time is
separated. Instead, four dimensions need to be imagined simultaneously as a
space-time continuum in which the different directions are connected. THIS
IS AWESOME!

While time
travel has only been possible in popular movies and books, a scientist has
found that in reality, there’s more to time travel than what we previously
believed.

A researcher
has created a new, revolutionary model that reveals—mathematically—time travel
is in fact possible. While it seems to work mathematically, experts have yet to
come up with the ‘right’ materials to create a working ‘time machine’.

The study
was recently published in the IOPscience Journal Classical and Quantum Gravity
and argues 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. (Source)

Ben Tippett,
a mathematics and physics instructor at the University of British Columbia’s Okanagan campus has revealed that time travel is at least mathematically
possible.

“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,” revealed Tippett.

According to
a newly published study, Tippet concludes that space should NOT be divided into
three dimensions—where time is separated. Instead, Tippett says four dimensions
need to be imagined simultaneously as a space-time continuum in which the
different directions are connected. Time travel.

Based on
Einstein’s theory—the researchers argues that the curvature of space-time is
responsible for the curved orbits of the planets in the universe.

The
researcher argues that if space-time was not ‘curved’ planets in the universe
would travel in a straight line.

Imagine
yourself standing next to a MASSIVE STAR. There, space-time geometry becomes
curved making all straight trajectories of nearby cosmic bodies to bend,
following a curved path around the star.

“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
study, Tippett came up with a mathematical model called Traversable Acausal
Retrograde Domain in Space-time or more charismatically called TARDIS. Tippett describes it as a bubble of
space-time geometry which is able to carry contents back and forth through
space. This ‘bubble’ moves through space-time at a speed greater than the speed
of light times 8, which consequently 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,
while the researcher says its mathematically possible to travel in time, he
doubts that anyone will ever build a working time machine in the near future.

“HG Wells popularized the term ‘time machine’ and he left people with the thought that an explorer would need a ‘machine or special box’ to actually accomplish time travel,” Tippett says.

“While it is 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,” concluded Tippett.
