The nature of time has plagued thinkers for as long as we've tried to understand the world we live in. Intuitively, we know what time is, but try to explain it, and we end up tying our minds in knots.

The world's most sensitive table-top interferometric system—a miniature version of miles-long gravitational-wave detectors like LIGO—has completed its first science run. The Quantum Enhanced ...

On January 22, 2025, physicists unveiled a groundbreaking discovery that could revolutionize our understanding of the universe and potentially unlock the secrets of time travel. The existence of ...

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 ...

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 ...

"We will push the limits of what we can observe, and use every gravitational lens we detect with Roman to pin down the particle nature of dark matter." When you purchase through links on our site, we ...
