Time travel is always fantasised by human race in form of fictional novels or movies or documentaries or even cartoons (Doremon!). But why are we so escalated about time travel? Are we too regretful about our pasts or are we too overzealous about finding what our future will be like? I think it could be either of those but it is more about curiosity. Curiosity defines human beings and vice-versa. But time travel has always been a fantasy, well, it is something more than that now, it is possible.
A Canadian researcher have been seriously crunching up numbers and has finally come up with a mathematical model which shows that time travel is actually feasible but the only drag is that it is possible mathematically (haha!). Benjamin Tippett, a mathematics and physics instructor at the University of British Columbia in Canada, and research partner David Tsang has come up with a mathematical model of what people could call a time machine; but just mathematically.
Tippett created a formula based on Albert Einstein’s theory of general relativity, which states that huge cosmic objects like stars and black holes distort space and time. Tippett describes ‘TARDIS’ which is a bubble in space-time geometry that could carry a passenger forward and backward in time in a circular path by using the curvatures in space-time.
Don’t get too excited, though, because a real-life Dr. Who TARDIS may still be far from fruition or perhaps even unlikely to be created ever. While being mathematically feasible, it is not possible to actually build it because we need materials which is called ‘exotic’ matter which will blend the space-time in every possible way. But where is that exotic matter? Nowhere. So where is the time machine? Nowhere other than mathematics.
But don’t lose hope, because numbers don’t lie and crunching the right ones can bring previously impossible, if not completely fictional, concepts to reality. Just like how space is one area which was once an unreachable place but now, thanks to the numbers that allow us to travel and explore around in space. So TARDIS may seem to be a too far-fetched idea now but it can be a reality in future.
