Stress is a very real factor in the structure of our universe. Not the kind of stress that students experience when taking a test, but rather the physical stresses that affect everyday objects.

Sensors buried deep in the Antarctic ice may help physicists figure out how gravity works in the quantum realm, the smallest scale of existence. A team of physicists says they’ve figured out how to ...

The scientific world has long known that atoms form the basic building blocks of matter, but CERN is interested in peering beyond the atom into the mesonic and baryonic soup that gives rise to matter ...

Quantum chromodynamics, or QCD, is the theory of the strong interaction between quarks and gluons. Lattice QCD uses supercomputers to explore 'tantalizing hints' of new physics in discrepancies ...

When most of us picture an atom, we think about a small nucleus made of protons and neutrons orbited by one or more electrons. We view these electrons as point-like while rapidly orbiting the nucleus.

They say you can never trust an atom because they make up everything. This week, we’re shrinking down and getting literally into the heart of the matter. We’ve covered the periodic table and all its ...

Almost anything is possible — at least for a subatomic particle. One of the many mystifying consequences of quantum mechanics — the rules that govern the behavior of tiny subatomic particles — is that ...

In 2015, the world's most powerful atom smasher, the Large Hadron Collider, will restart. The particle accelerator has already discovered the Higgs boson, the so-called "God particle," and when it ...
