Higgs boson

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.

In this article adapted from his new book, "Waves in an Impossible Sea," physicist Matt Strassler explains that the origin of mass in the universe has a lot to do with music.

One of the quantum fields that fills the universe is special because its default value seems poised to eventually change, changing everything.

Several areas of physics suggest reasons to think that unobservable universes with different natural laws could lie beyond ours. The theoretical physicist David Kaplan talks with Steven Strogatz about the mysteries that a multiverse would solve.

Quantum field theory may be the most successful scientific theory of all time, but there’s reason to think it’s missing something. Steven Strogatz speaks with theoretical physicist David Tong about this enigmatic theory.

The key to understanding the origin and fate of the universe may be a more complete understanding of the vacuum.

A hidden link has been found between two seemingly unrelated particle collision outcomes. It’s the latest example of a mysterious web of mathematical connections between disparate theories of physics.

Einstein’s description of curved space-time doesn’t easily mesh with a universe made up of quantum wavefunctions. Theoretical physicist Sean Carroll discusses the quest for quantum gravity with host Steven Strogatz.

Physicists are reexamining a longstanding assumption: that big stuff consists of smaller stuff.
