Gravity has become an unlikely viral villain, blamed for an imagined global blackout in which the planet briefly lets go of ...

Physicists are quietly advancing a radical idea: time might not be a single, thin line but a full three‑dimensional landscape. If that is true, the equations that describe the universe have to be ...

By studying ripples in space-time, physicists are testing wheather dark energy might stem from hidden dimensions, elusive ...

Like stretch marks left on skin that expanded too quickly or cracks embedded in freezing ice, cosmic strings are artifacts of ...

A fringe new theory suggests that time is the fundamental structure of the physical universe, and space is merely a byproduct. According to Gunther Kletetschka, a geologist — not a physicist, you’ll ...

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 ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

Unfortunately, any work you do in the universe will have to be done the old-fashioned way. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. There ...

Whether space-time exists should neither be controversial nor even conceptually challenging, given the definitions of “space-time,” “events” and “instants.” The idea that space-time exists is no more ...

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.

With humanity moving farther and farther out into space on a regular basis, this becomes much more of a practical problem. Not only do satellite clocks need to be adjusted as they are placed in higher ...
