physics

A new measurement appears to have eliminated an anomaly that had captivated physicists for nearly a decade.

There are many different ways to think about probability. Quantum mechanics embodies them all.

Since the 1970s, physicists have described black holes using borrowed versions of the laws of thermodynamics. But are black holes really thermodynamic systems? Craig Callender worries that the analogy has been stretched too far.

While studying materials made from DNA-coated nanoparticles, researchers found a new form of this matter: lattices in which smaller particles roam like electrons in metallic bonds.

Researchers have confirmed rumors of a black hole collision that challenges our ideas about how black holes form.

The theoretical particle physicist Ann Nelson, who died on August 4 at age 61, was a font of brilliant ideas and a champion of ending discrimination in the field.

Does objective, perfect randomness exist, or is randomness merely a product of our ignorance?

How do black holes merge and make gravitational waves? Maybe with a little help from their friends.

New measurements could upend the standard theory of the cosmos that has reigned since the discovery of dark energy 21 years ago.
