New Proof Finds the ‘Ultimate Instability’ in a Solar System Model
For the first time, mathematicians have proved that planetary orbits in a solar system will always be unstable.
Physicists Create Elusive Particles That Remember Their Pasts
In two landmark experiments, researchers used quantum processors to engineer exotic particles that have captivated physicists for decades. The work is a step toward crash-proof quantum computers.
Is Perpetual Motion Possible at the Quantum Level?
A new phase of matter called a “time crystal” plays with our expectations of thermodynamics. The physicist Vedika Khemani talks with Steven Strogatz about its surprising quantum behavior.
Tiny Jets on the Sun Power the Colossal Solar Wind
A new analysis argues that ubiquitous eruptions in the sun’s corona explain the vast flow of charged particles seen streaming out through the solar system.
The Electron Is So Round That It’s Ruling Out Potential New Particles
If the electron’s charge wasn’t perfectly round, it could reveal the existence of hidden particles. A new measurement approaches perfection.
How to Tame the Infinities Hiding in the Heart of Particle Physics
In the math of particle physics, every calculation should result in infinity. The set of techniques known as “resurgence” points toward an escape.
