It took 100 years to discover all the physics particles that have thus far been observed. It took the Large Hadron Collider four months.
That's the report Monday from the International Conference on High-Energy Physics in Paris, where LHC researchers announced they've successfully retraced the steps of earlier particle accelerators. The final step was the likely view of a super-heavy and short-lived particle called the top quark, first seen in 1995 at Fermilab's Tevatron accelerator near Chicago.
"They have re-found all the known particles in the standard model," the successful but ultimately insufficient explanation that … Read more
