The MATH of time travel REVEALED Scientists  says we CAN travel in time
  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.
  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.
  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  backwards 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.
