A new proposal makes the case that paraparticles — a new category of quantum particle — could be created in exotic materials. The post ‘Paraparticles’ Would Be a Third Kingdom of Quantum Particle first appeared on Quanta Magazine

A new suggestion that complexity increases over time, not just in living organisms but in the nonliving world, promises to rewrite notions of time and evolution. The post Why Everything in the Universe Turns More Complex first appeared on Quanta Magazine

Astronomers are ready to search for the fingerprints of life in faraway planetary atmospheres. But first, they need to know where to look — and that means figuring out which planets are likely to have atmospheres in the first place.

In math and computer science, researchers have long understood that some questions are fundamentally unanswerable. Now physicists are exploring how even ordinary physical systems put hard limits on what we can predict, even in principle.

Quantum calculations amount to sophisticated estimates. But in 1931, Hans Bethe intuited precisely how a chain of particles would behave — an insight that had far-reaching consequences. The post How Hans Bethe Stumbled Upon Perfect Quantum Theories first appeared on Quanta Magazine

Emmy Noether showed that fundamental physical laws are just a consequence of simple symmetries. A century later, her insights continue to shape physics. The post How Noether’s Theorem Revolutionized Physics first appeared on Quanta Magazine

Is the universe flat and infinite, or something more complex? We can’t say for sure, but a new search strategy is mapping out the subtle signals that could reveal if the universe had a shape. The post Cosmologists Try a New Way to Measure the Shape of the Universe first appeared on Quanta Magazine

Heat is supposed to ruin anything it touches. But physicists have shown that an idealized form of magnetism is heatproof. The post Heat Destroys All Order. Except for in This One Special Case. first appeared on Quanta Magazine

Inside the proton, quarks and gluons shift and morph their properties in ways that physicists are still struggling to understand. Rithya Kunnawalkam Elayavalli brings to the problem a perspective unlike many of their peers. The post The Physicist Decoding the Nonbinary Nature of the Subatomic World first appeared on Quanta Magazine

The first planet beyond our solar system was identified just 30 years ago. Since then, thousands have been found and characterized. As we look for more, exoplanet experts are also probing for signs of alien biospheres hundreds of light-years away. In this episode, co-host Janna Levin speaks with astrophysicist and astrobiologist Lisa Kaltenegger about how we’ll know we’re not alone in the cosmos. The...

Physicists discovered strange supersolids, constructed new kinds of superconductors, and continued to make the case that the cosmos is far weirder than anyone suspected. The post The Year in Physics first appeared on Quanta Magazine
