Scientists report the possible discovery of primordial gravitational waves, ripples in space-time that carry a record of how the universe began.

New calculations suggest physicists may someday discover a fundamental theory of gravity, but it could require a radical new perspective on the universe.

A new analysis strengthens the case that gamma rays emanating from the center of the Milky Way come from dark matter particles known as WIMPs.

A daring speculation offers a potential way forward in one of the great unsolved problems of mathematics: the behavior of the Navier-Stokes equations for fluid flow.

With a new approach that treats the universe as a fluid, cosmologists plan to tease out the fine details of the Big Bang from its behavior and evolution.

An MIT physicist has proposed the provocative idea that life exists because the law of increasing entropy drives matter to acquire lifelike physical properties.

By investigating the central role played by knots in fluids and fields, physicists hope to unravel long-standing mysteries of turbulence.

Physicists have devised experiments that can probe the interface between quantum mechanics and general relativity.

Physicists have completed a new round of searches for the answer to why matter dominates over antimatter. But the radioactive decay that would solve the puzzle is evading them.
