A new thought experiment indicates that quantum mechanics doesn’t work without strange numbers that turn negative when squared.

In a second season of enlightened conversations, Steven Strogatz and leading researchers nourish our pandemic-starved minds.

Twenty years ago, physicists set out to investigate a mysterious asymmetry in the proton’s interior. Their results, published today, show how antimatter helps stabilize every atom’s core.

An overlooked but powerful driver of cloud formation could accelerate the loss of polar sea ice.

One black hole is nice, but astrophysicists can do a lot more science with 50 of them.

A new study shows that extreme black holes could break the famous “no-hair” theorem, and in a way that we could detect.

Micrometeorites constantly fall on every corner of Earth. Matthew Genge is using these shards of interplanetary space to understand Earth and its place in the solar system.

Small and cold, Mars has long been considered a dead planet. But a series of recent discoveries has forced scientists to rethink how recently its insides stopped churning — if they ever stopped at all.

Small black holes were nowhere to be found, leading astronomers to wonder if they didn’t exist at all. Now a series of findings, including a “unicorn” black hole, has raised hopes of solving the decade-long mystery.
