If you want to explain what was and what is, you need particle physics. Because everything we see consists of molecules and atoms, and atoms in turn consist of atomic nuclei and electrons. The atomic ...

Electromagnetism and the weak nuclear force are two distinct fundamental forces. That wasn’t always the case. How many fundamental forces are there in our universe? For particle physicists, answering ...

It’s a fundamental principle of physics that particles with opposite charges attract each other, while those with the same charge repel. But now, scientists at the University of Oxford have found that ...

As far as we know, at the most basic level, the universe is made up of fundamental particles and controlled by four fundamental forces. The Standard Model explains these fundamental particles and ...

From the outside, the high-speed collisions of atomic nuclei inside particle accelerators like CERN’s Large Hadron Collider (LHC) may seem like they have very little in common with more mundane ...

This spring, at a meeting of Syracuse University’s quark physics group, Ivan Polyakov announced that he had uncovered the fingerprints of a semi-mythical particle. “We said, ‘This is impossible. What ...

Some physicists think there is a unit of matter more fundamental than what has been experimentally confirmed to date. They think that everything in the universe is made of tiny vibrating strands of ...

The ATLAS collaboration recently measured the strength of the strong force to a record level of precision, but there’s still a long way to go toward understanding this fundamental force. In September, ...

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 ...
