The team that discovered gravitational waves put their data online. Now an independent group of researchers claims that they’ve found what might be a serious problem.
Recent calculations tie together two conjectures about gravity, potentially revealing new truths about its elusive quantum nature.
A different kind of dark matter could help to resolve an old celestial conundrum.
New math shows how, contrary to conventional scientific wisdom, conscious beings and other macroscopic entities might have greater influence over the future than do the sum of their microscopic components.
Join David Kaplan on a virtual-reality tour showing how the sun, the Earth and the other planets came to be.
A series of observations at the very edge of the universe has reignited a debate over what lifted the primordial cosmic fog.
Time isn’t just another dimension, argues Tim Maudlin. To make his case, he’s had to reinvent geometry.
As physicists extend the 19th-century laws of thermodynamics to the quantum realm, they’re rewriting the relationships among energy, entropy and information.
