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

In the universe's earliest moments, particles existed in an unimaginably hot plasma, whose behaviour was governed by deeply complex webs of interaction between individual particles. Today, researchers ...

The hunt for new physics is back on. The world’s most powerful machine for smashing high-energy particles together, the Large Hadron Collider (LHC), has fired up after a shutdown of more than three ...

In a paper in Nature, the ALICE Collaboration 1 reports that data from high-energy collisions between protons can be used to investigate the little-understood nuclear forces between protons and ...

Understand perfectly inelastic collisions through a simple clay ball example. This video explains how momentum is conserved while kinetic energy is not, helping you visualize what happens when objects ...
