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 ...

Gravitational waves are energy-carrying waves produced by the acceleration or disturbance of massive objects. These waves, ...

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 ...

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...

From Newton’s falling apple to Einstein’s curved spacetime, our understanding of gravity has come a long way, yet this familiar force remains one of the biggest puzzles in physics.

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 ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. An abstract illustration of quantum particles entangling. New research aims to unite gravity with ...

We can never 100% prove that the constants really are constant. There is a set of very special numbers, known as the fundamental constants of nature, that cannot be explained. Where do they come from?

"It may take decades before we find out what really happens in black holes." Reports of the singularity's demise may have been premature. Earlier this year, new research suggested a potential solution ...
