Here’s what you’ll learn when you read this story: Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration ...

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 ...

Massive ripples in the very fabric of space and time wash over Earth constantly, although you'd never notice. An astrophysicist is trying a new search for these gravitational waves. University of ...

The original version of this story appeared in Quanta Magazine. In the fall of 2022, a Princeton University graduate student named Carolina Figueiredo stumbled onto a massive coincidence. She ...

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.

The first time you experience weightlessness in space, Tom Marshburn told me, all the noise and pressure of launch suddenly disappear. One moment, the roar of engines shakes every bone in your body; ...
