In new computer experiments, artificial-intelligence algorithms can tell the future of chaotic systems.
New results from a decades-old experiment were initially touted as further evidence for dark matter. But independent scientists have cast serious doubt on that claim.
Two methods of measuring the neutron's longevity give different answers, creating uncertainty in cosmological models. But no one has a clue what the problem is.
Edward Witten reflects on the meaning of dualities in physics and math, emergent space-time, and the pursuit of a complete description of nature.
Astronomers are mystified by a strange star explosion in a distant galaxy that might be a relic from an earlier cosmological era.
Physicists theorize that a new “traversable” kind of wormhole could resolve a baffling paradox and rescue information that falls into black holes.
A new idea called the “information bottleneck” is helping to explain the puzzling success of today’s artificial-intelligence algorithms—and might also explain how human brains learn.
Take chemistry, add energy, get life. The first tests of Jeremy England’s provocative origin-of-life hypothesis are in, and they appear to show how order can arise from nothing.
Recent calculations tie together two conjectures about gravity, potentially revealing new truths about its elusive quantum nature.
Physicists propose that dark matter is capable of changing phases—into an exotic superfluid with zero viscosity.
