Time travel BOMBSHELL: It IS possible… and THIS is how

The idea of time travel has been intriguing humans for centuries, with many claiming the feat would be impossible. However, one scientist has now come up with a formula to achieve time travel – but there is a catch. Doctoral student Caroline Mallary, at the University of Massachusetts Dartmouth has created a Back to The Future DeLorean-type time machine, but to make it work, the car would need a object at its centre with an infinite mass.

Something with an infinite mass would have an extremely strong gravitational pull.

Previous research has shown that gravity has the ability to warp spacetime – which is the connection of time and the physical universe.

Albert Einstein theorised that if you were to situate yourself on the edge of a black hole, which have such a powerful gravitational pull that not even light can escape, time would pass more slowly, which in theory would make time travel possible.

Using this knowledge, Gaurav Khanna, Professor of Physics, University of Massachusetts Dartmouth and Ms Mallary’s tutor, believes his student’s design could achieve time travel.

Prof Khanna said: “Mallary’s model consists of two super long cars – built of material that is not exotic, and have positive mass – parked in parallel.

“One car moves forward rapidly, leaving the other parked. Mallary was able to show that in such a setup, a time loop can be found in the space between the cars.

“If you suspect there is a catch, you are correct. Mallary’s model requires that the centre of each car has infinite density.

“That means they contain objects – called singularities – with an infinite density, temperature and pressure.

“Moreover, unlike singularities that are present in the interior of black holes, which makes them totally inaccessible from the outside, the singularities in Mallary’s model are completely bare and observable, and therefore have true physical effects.

“Physicists don’t expect such peculiar objects to exist in nature either. So, unfortunately a time machine is not going to be available anytime soon.”
