Travel for old time’s sake...
BACK to the Future showed us the magic of time travel as Marty Mcfly and eccentric inventor Doc Brown whizzed through space in a modified Delorean.
Doctor Who has also flipped back and forth through time for years in the famous Tardis.
But this is science fiction, the stuff of movies and television. It’s not real, right?
Well perhaps it’s time to think again as this brain-boggling documentary investigates the latest theories into real, actual, bona fide time travel.
There is talk of quantum entanglement, time crystals, dark energy, worm holes and travelling faster than the speed of light.
There are professors scribbling incomprehensible equations on whiteboards. If you happen to lose concentration for a moment, you’re likely to be completely lost.
But as it sets out the real possibilities of time travel, it is fascinating. Could scientists really build a time machine?
Professor Ronald Mallett is one man who is working out how to break the time barrier.
“He’s not crazy,” insists the narrator, “he’s a highly respected professor of physics”.
Ronald became obsessed with time travel as a child after his father died, wanting to go back in time to save him.
Elsewhere, astrophysicist Professor Tamara Davis explains how an astronaut actually went back in time, albeit by only 0.2 seconds.
We are told that breaking the fourth dimension is simply a matter of, er, time. So in the future will we all be visiting our ancestors and speeding back to place bets on the football?
It’s all a bit bonkers.
