The ability to jump forward and backwards in time has long fascinated science fiction writers and physicists alike. So is it really possible to travel into the past and the future?
It's a monumental head-scratcher known as the 'grandfather paradox', but a few years ago physics student Germain Tobar, from the University of Queensland in Australia, worked out how to "square the numbers" to make time travel viable without the paradoxes.
26 kwi 2023 · Time traveling to the near future is easy: you’re doing it right now at a rate of one second per second, and physicists say that rate can change. According to Einstein’s special theory of...
26 paź 2023 · Send a spaceship into the depths of space at speed, and its passengers will experience time and distance differently to the observers watching their journey from afar. This contrast comes courtesy of relativity, a theory that's been tested successfully time and time again on all manner of scales.
