Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

Intuitively, we know what time is, but try to explain it, and we end up tying our minds in knots. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

A colossal structure in the distant Universe is defying our understanding of how the Universe evolved. In light that has traveled for 6.9 billion years to reach us, astronomers have found a giant, ...

Physicists hope that understanding the churning region near singularities might help them reconcile gravity and quantum mechanics. At the beginning of time and the center of every black hole lies a ...

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 ...
