A new particle accelerator has just begun operation. It is the most powerful accelerator of its kind on Earth and will allow physicists to study some of the rarest matter in the universe.
When two particles are entangled, the state of one is tied to the state of the other.

A multitude of experiments have shown the mysterious phenomena of quantum mechanics to be how the universe functions. The scientists behind these experiments won the 2022 Nobel Prize in physics.
A decadelong experiment produced the most accurate measurement yet of the mass of W bosons. These particles are responsible for the weak force, and the result is more evidence for undiscovered physics.
Experiments at the Large Hadron Collider in Europe, like the ATLAS calorimeter seen here, are providing more accurate measurements of fundamental particles.

Physicists know a lot about the most fundamental properties of the universe, but they certainly don’t know everything. 2021 was a big year for physics – what was learned and what’s coming next?
For 15 years, there has been a mismatch in physics. A particle called the muon wasn’t behaving the way theory predicted it should. A new theory and new experiment might solve this problem.

Scientists think they may have found a new clue about the subatomic world around us.

If the finding really is the result of new fundamental particles then it will finally be the breakthrough that physicists have been yearning for for decades.
