Scientists working with the Large Hadron Collider (LHC) have discovered three subatomic particles never seen before as they work to unlock the building blocks of the universe
A decade ago, the Large Hadron Collider, Earth's most powerful particle accelerator, proved the existence of an subatomic particle called the Higgs boson
thought to be a fundamental building block of the universe dating back to the big bang billions of years ago.
Now, physicists at the European Organization for Nuclear Research (CERN) on the Swiss-French border are restarting the collider with the aim of understanding more about the Higgs boson
other subatomic particles and the mysteries of dark matter -- an invisible and elusive substance that can't be seen because it doesn't absorb, reflect or emit any light.
Consisting of a ring 27 kilometers (16.7 miles) in circumference, the Large Hadron Collider -- located deep underneath the Alps -- is made of superconducting magnets chilled to ‑271.3°C (-456 F)
which is colder than outer space. It works by smashing tiny particles together to allow scientists to observe them and see what's inside.
