They twist and turn on their way to Earth, which has made it nearly impossible to identify the colossal monsters that create them.
Long-awaited news from Fermilab’s Muon g-2 team may resolve a tantalizing conflict between nature and theory. But a separate calculation clouds the picture.
Spurred on by experiments that scramble the ordering of causes and their effects, some physicists are figuring out how to abandon causality altogether.
Twenty years ago, physicists began investigating a mysterious asymmetry inside the proton. Their results show how antimatter helps stabilize every atom’s core.
Micrometeorites fill every corner of our planet. Matthew Genge is using these shards of interplanetary space to understand Earth and its place in the solar system.
Astronomers get their wish—new ultra-precise distance measurements between Earth and the stars—but that only intensifies a cosmic crisis.
His incompleteness theorems destroyed the search for a mathematical theory of everything. Nearly a century later, we’re still coming to grips with the consequences.
Researchers are discovering that magnetic fields permeate much of the cosmos. If these fields date back to the Big Bang, they could solve a cosmological mystery.
Researchers say there are three possible explanations for the anomalous data: One is mundane. Two would revolutionize physics.
What happens to a black hole as it decays? Investigating the possibilities has led researchers in recent years to major clues about quantum gravity.
