For decades, physicists have relied on the principle of symmetry to simplify and understand the complex behaviors of subatomic particles. Symmetry in physics basically means that some rules of nature ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

Physicists at the European Organization for Nuclear Research (CERN) announced on 5 July that they had observed three exotic new types of particles that had never been seen before—shining a light into ...

Physicists at Cern have discovered a plethora of new exotic particles being created in the collisions produced by the Large Hadron Collider over the past few years. So many have been found, in fact, ...

A view inside a proton moving at nearly the speed of light toward the viewer with its spin pointing horizontally shows differences in the spatial distributions of the momentum of up (left) and down ...

Protons might be stretchier than they should be. The subatomic particles are built of smaller particles called quarks, which are bound together by a powerful interaction known as the strong force. New ...

Top result: An artist's impression of top-quark entanglement. The line between the particles emphasizes the non-separability of the top-quark pair, which is produced by LHC collisions and recorded by ...

Newly released observations of the top quark -- the heaviest of all known fundamental particles -- could topple the standard model of particle physics. Data from collisions at the Tevatron particle ...

Some neutron stars probably have something strange lurking in their cores, according to a recent study. Neutron stars are already some of the most peculiar objects in the universe. They contain enough ...
