‘Paradox-Free’ Time Travel Is Theoretically Possible

 The question of whether time travel is theoretically possible remains a fascinating topic for scientists. The concept of time loops, as predicted by Einstein’s theory of general relativity, has been a subject of interest in the field of dynamics.

As movies such as The Terminator, Donnie Darko, Back to the Future and many others show, moving around in time creates a lot of problems for the fundamental rules of the Universe: if you go back in time and stop your parents from meeting, for instance, how can you possibly exist in order to go back in time in the first place?

Physics student Germain Tobar from the University of Queensland in Australia has worked out a way to “square the numbers” to make time travel viable without paradoxes, reports sciencealert.com.

Tobar’s work suggests that space-time can potentially adapt itself to avoid paradoxes. For example, if a time traveler journeys into the past to stop a disease from spreading, the disease would still escape some other way, removing the paradox....<<<Read More>>>...
