Quantum Theory's Most Incredible Prediction
Quantum field theory is notoriously complicated, built from mind-bendingly abstract mathematics. But are the underlying rules of reality really so far from human intuition? Or are physicists just showing off? For better or worse, the...

Mind the (Solar System's) Gap
Giant disks around baby stars filled with gas and dust provide the material to make all sorts of planets, and new evidence proves that our solar system’s had a massive gap in it! And the water vapor in Jupiter’s moon, Europa, might not...

Making a Realistic Simulation of the Sun
We’ve created simulations to recreate the difference in time it takes for the Sun’s equator and poles to complete rotations, and the way we’ve solved is a bit surprising. And it looks like the Milky Way may not be great at mixing metals,...
