What makes up the matter we perceive in the universe? To start, there are the usual suspects, like electrons, protons, quarks and neutrinos. But if those particles aren't strange enough for you, I'm ...

Physicists have struggled for seven decades with the question of why there is more matter in the universe than antimatter.

Smashing atomic nuclei together at mind-bending speeds recreates the fiery conditions of the early universe and scientists are finally getting a better handle on what happens next. A sweeping new ...

Physicists at the ATLAS detector of the Large Hadron Collider (LHC) have spotted top quarks — the heaviest of all known elementary particles — that were produced by the collision of atomic nuclei 1.

A new study broadens the horizon of knowledge about how matter behaves under extreme conditions and helps to solve some great unknowns about the origin of the universe. An international team of ...
