Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that describe gravity, quantum fields and the structure of spacetime now allow ...

Physicists are quietly advancing a radical idea: time might not be a single, thin line but a full three‑dimensional landscape ...

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

The laws of physics imply that the passage of time is an illusion. To avoid this conclusion, we might have to rethink the reality of infinitely precise numbers. Strangely, although we feel as if we ...

Physicists uncover a universal limit on timekeeping precision, proving that anything from heartbeats to ocean waves can be a ...

The energy requirements for manipulating spacetime on a scale necessary for time travel are astronomical. Time travel remains a tantalising concept, captivating the human imagination and stirring ...

IMAGINE standing outside the universe. Not just outside space, but outside time too. From this spectacular vantage point, you gaze down upon the universe. At one end you see its beginning: the big ...
