A new theory explains the seemingly irreversible arrow of time while yielding insights into entropy, quantum computers, black holes, and the past-future divide.
New calculations suggest physicists may someday discover a fundamental theory of gravity, but it could require a radical new perspective on the universe.
Physicists have devised experiments that can probe the interface between quantum mechanics and general relativity.
Physicists have discovered a jewel-shaped geometric object that challenges the notion that space and time are fundamental constituents of nature.
An interview with the Berkeley chemist K. Birgitta Whaley on the promise and challenge of translating quantum biology into practical quantum devices.
New findings suggest that beneath the surface of quantum theory lies a vibrant string theory world where some matter corresponds to black holes in higher dimensions.
An interview with the Nobel Prize-winner David J. Gross on the confusing state of theoretical physics.
A radical theory predicting the existence of “time crystals” — perpetual motion objects that break the symmetry of time — is being put to the test.
