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

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

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 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 ...

Contemporary physics has learned to describe the universe with unprecedented precision. Yet when it tries to say what time is, it stumbles again and ...
