No one has yet managed to travel through time – at least to our knowledge – but the question of whether or not such a feat would be theoretically possible continues to fascinate scientists. It's a ...

Even if it turns out that time loops never take shape, studying them provides key insights into the deepest rules of reality.

In a peer-reviewed paper, a scientist says he has mathematically proven the physical feasibility of a specific kind of time travel. The paper appears in Classical and Quantum Gravity. Germain Tobar ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

Time travel might seem like nothing more than science fiction, but scientists actually say that isn't the case at all. Time travel could actually be possible with wormholes and other mechanics.

Time travel is deterministic and locally free, a paper says—resolving an age-old paradox. This follows research observing that the present is not changed by a time-traveling qubit. It’s still not very ...
