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 ...

Asymmetric collapse: Simulations of core-collapse supernovae indicate that existing gravitational-wave detectors such as LIGO could spot telltale signs of cosmic distortions known as gravitational ...

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

The original version of this story appeared in Quanta Magazine. At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these ...

A mathematical test for the nature of space-time – the fabric of physical reality – may be the first step towards novel computer-like devices that process information using gravity. Eleftherios-Ermis ...
