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

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

The answer comes from a counterintuitive result of special relativity, a field of physics which is notoriously difficult to ...
