When neutron stars collide, they create a powerful gravitational-wave signal, with the post-merger remnant ringing like a ...

What if time is not as fixed as we thought? Imagine that instead of flowing in one direction -- from past to future -- time could flow forward or backward due to processes taking place at the quantum ...

I grew up collecting Pokémon cards, and it's a hobby I picked back up in spring 2023 when my younger brother, Tanner, got back into collecting, too. Since then, we've opened plenty of packs and ...

Predictions are uncertain, but the solar system may be pushed farther from the galactic core or even ejected entirely from the new galaxy.

The passing gravitational waves “stretch or contract the universe by around 20 meters [about 65 feet] or so,” says Matthew ...

By observing tiny ripples in spacetime called "gravitational waves" that propagate away from colliding black holes, ...
