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.
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.
As physics prepares for ambitious projects like the Large Synoptic Survey Telescope, the field is seeking new methods of data-driven discovery.
Physicists have discovered a jewel-shaped geometric object that challenges the notion that space and time are fundamental constituents of nature.
Whispers of the elusive particles are becoming stronger with a series of signals that appear to be zeroing in on a leading contender.
Decades of confounding experiments have physicists considering a startling possibility: The universe might not make sense.
An interview with the Nobel Prize-winner David J. Gross on the confusing state of theoretical physics.
As the elegant theory of supersymmetry continues to fail experimental tests, physicists debate whether to change course and what the future holds for particle physics.
