A Super Sensitive Dark-Matter Search Yields Strange Results
Researchers say there are three possible explanations for the anomalous data: One is mundane. Two would revolutionize physics.
Is the Universe a Hologram? Maybe! This Math Trick Shows How
Physicists designed a holographic model for a universe similar to our own that could bring us closer to a quantum theory of gravity.
Space and Time Could Be a Quantum Error-Correcting Code
The fabric of space-time may get its robustness from a network of quantum particles, according to a principle called quantum error correction.
Confirmed! Those LIGO Gravitational Wave Signals Were Real
Two independent papers vanquish lingering doubts about LIGO’s historic discovery of gravitational waves.
The Peculiar Math That Could Underlie the Laws of Nature
New findings are fueling an old suspicion that fundamental particles and forces spring from strange eight-part numbers called “octonions.”
The Universe Is Not a Simulation, but We Can Now Simulate It
Computer simulations have become so accurate that cosmologists can now use them to study dark matter, supermassive black holes, and other mysteries of the real evolving cosmos.

Machine Learning’s ‘Amazing’ Ability to Predict Chaos
In new computer experiments, artificial-intelligence algorithms can tell the future of chaotic systems.
Trouble Detected in Infamous Dark Matter Signal
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.
How Long Can a Neutron Live? Depends on Who You Ask
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.
