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

In the mid-19th century, Bernhard Riemann conceived of a new way to think about mathematical spaces, providing the foundation for modern geometry and physics.

Physicists have engineered photons that behave as if they inhabit a space far richer than the familiar three dimensions, ...

(A) Coil system. (B) Tank and helical microswimmer. (C) Real experimental image. (D) Helical microswimmer with detailed shape parameters. The red dashed line indicates the body axis of the helical ...

Physicists of the 19th century assumed that space was distinct from time – and two researchers now suspect they were correct to do so. Their conclusion, which comes from considering the behaviour of ...
