Whispers of the elusive particles are becoming stronger with a series of signals that appear to be zeroing in on a leading contender.

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.

Theoretical cosmologists are piecing together a cosmic origin story from a surprising anomaly in the recently released Planck satellite image.

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.

A radical theory predicting the existence of “time crystals” — perpetual motion objects that break the symmetry of time — is being put to the test.

Glass and other strange materials have long confounded textbook definitions of what it means to be solid. Now, two groups of physicists propose a new solution to the riddle.
