What's up in

A startling experimental discovery about how fluids behave started a wave of important mathematical proofs.

The laws of physics stay the same no matter one’s perspective. Now this idea is allowing computers to detect features in curved and higher-dimensional space.

Giant blobs nestled deep in the Earth may influence everything from the structure of island chains to mass-extinction events.

Physicists saw a black hole for the first time, debated the expansion rate of the universe, pondered the origin of time and modeled the end of clouds.

Snow crystals come in two main types. The “pope” of snowflake physics has a new theory that explains why.

Researchers have spent centuries looking for a scenario in which the Euler fluid equations fail. Now a mathematician has finally found one.

A study challenged the evidence for the mysterious antigravitational force known as dark energy. Then cosmologists shot back.

After a space telescope disintegrated, astrophysicists had little hope of understanding how supermassive black holes agitate giant galaxies. Then they invented a hack.

By considering simple symmetries, physicists working on the “bootstrap” can rediscover the basic form of the known forces that shape the universe.
