The puzzling behavior of black hole interiors has led researchers to propose a new physical law: the second law of quantum complexity. The post In New Paradox, Black Holes Appear to Evade Heat Death first appeared on Quanta Magazine

Several areas of physics suggest reasons to think that unobservable universes with different natural laws could lie beyond ours. The theoretical physicist David Kaplan talks with Steven Strogatz about the mysteries that a multiverse would solve. The post Are There Reasons to Believe in a Multiverse? first appeared on Quanta Magazine

For the first time, mathematicians have proved that planetary orbits in a solar system will always be unstable. The post New Proof Finds the ‘Ultimate Instability’ in a Solar System Model first appeared on Quanta Magazine

A new theory describes how particle interactions fuel fast magnetic reconnection, the process behind solar flares and other astrophysical jets. The post The Tiny Physics Behind Immense Cosmic Eruptions first appeared on Quanta Magazine

If we want to understand complex constructions, such as ourselves, assembly theory says we must account for the entire history of how such entities came to be. The post A New Idea for How to Assemble Life first appeared on Quanta Magazine

So-called “higher symmetries” are illuminating everything from particle decays to the behavior of complex quantum systems. The post A New Kind of Symmetry Shakes Up Physics first appeared on Quanta Magazine

If the electron’s charge wasn’t perfectly round, it could reveal the existence of hidden particles. A new measurement approaches perfection. The post The Electron Is So Round That It’s Ruling Out Potential New Particles first appeared on Quanta Magazine

In the math of particle physics, every calculation should result in infinity. The set of techniques known as “resurgence” points toward an escape. The post How to Tame the Endless Infinities Hiding in the Heart of Particle Physics first appeared on Quanta Magazine

There once was a cosmic seed that sprouted the Milky Way galaxy. Astronomers have discovered its last surviving remnants. The post Astronomers Dig Up the Stars That Birthed the Milky Way first appeared on Quanta Magazine

Last fall, a team of physicists announced that they had teleported a qubit through a holographic wormhole in a quantum computer. Now another group suggests that’s not quite what happened. The post Wormhole Experiment Called Into Question first appeared on Quanta Magazine

Cosmologists are using secondary signatures from the cosmic microwave background to map the universe’s hidden matter. The post Shadows in the Big Bang Afterglow Reveal Invisible Cosmic Structures first appeared on Quanta Magazine

A paper in Nature reports the discovery of a superconductor that operates at room temperatures and near-room pressures. The claim has divided the research community. The post Room-Temperature Superconductor Discovery Meets With Resistance first appeared on Quanta Magazine

New calculations suggest that the event horizons around black holes will ‘decohere’ quantum possibilities — even those that are far away. The post Black Holes Will Eventually Destroy All Quantum States, Researchers Argue first appeared on Quanta Magazine

There appear to be too many gamma rays coming from the sun. New higher-energy measurements reveal that this excess continues for a bit, then disappears — a cutoff that could help clarify what’s going on. The post Strange Solar Gamma Rays Discovered at Even Higher Energies first appeared on Quanta Magazine

The quantum energy teleportation protocol was proposed in 2008 and largely ignored. Now two independent experiments have shown that it works. The post Physicists Use Quantum Mechanics to Pull Energy out of Nothing first appeared on Quanta Magazine

Big Freeze, Big Rip, Big Crunch, Bounce or vacuum decay? Steven Strogatz speaks with theoretical cosmologist Katie Mack about the five ways that scientists think the universe could come to an end. The post How Will the Universe End? first appeared on Quanta Magazine
