Time travel is deterministic and locally free, a paper says —resolving an age-old paradox. This follows research observing ...

The ontological paradox arises because if time travel is possible, then the future, present and past will not be definite. If that is the case, then, the word origin would be meaningless.

But, of course, before we can even worry about paradox-free time travel, we have to figure out time travel at its core. Something MIT scientists may be close to doing in their search for dark matter .

In the peer-reviewed journal article, University of Queensland physicists say time is essentially self-healing. Changes in the past wouldn't necessarily cause a universe-ending paradox. Phew.

Time travel is, of course, purely science fiction, at least for right now. Various theories have suggested that time travel — including to the past — may indeed be possible based on our ...

The curious minds at Aperture explore the scientific theories behind time travel and the paradoxes that come with bending ...

Paradox-Free Time Travel While Preserving Freedom of Choice. That’s where young physicist Germain Tobar steps in. Under the supervision of physicist ...

Would-be time travellers have long wrestled with the grandfather paradox: if you change things in the past and prevent yourself ever existing, how did you time travel in the first place?

The rules of time-travel have been debated by scientists and sci-fi fans alike for years, but now a student physicist has been able to "square the numbers" to show how paradox-free time travel is ...
