Betting on the Future of Quantum Gravity

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

Gamma Ray Excess

Case for Dark Matter Signal Strengthens

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.


Big Bang Secrets Swirling in a Fluid Universe

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.

Physicists Eye Quantum-Gravity Interface

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


Search Escalates for Key to Why Matter Exists

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.
