The Large Hadron Collider is one of the largest machines in the world. Its purpose is to fire subatomic particles at each other so we can better see how they function.

What, exactly, does the Large Hadron Collider do? This video will break it down for you in just over a minute. | CBC News

The LHC is preparing to restart at almost double the collision energy of its previous run. The new energy will allow physicists to check previously untestable theories, and explore new frontiers in particle physics. When the LHC is on, counter-rotating beams of particles will be made to collide at four interaction points 100 metres underground, around which sit the huge detectors ALICE, ATLAS, CMS and LHCb. In the video above, engineers and technicians prepare these four detectors to receive the

Scientists Announce a Puzzling Discovery At The Large Hadron Collider! | The Secrets Of The Universe

Scientists at CERN's Large Hadron Collider have succeeded in transforming lead into gold, fulfilling an age-old alchemical dream using modern physics. The ALICE team achieved this by colliding lead nuclei at nearly the speed of light. The resulting electromagnetic fields caused three protons to be ejected from the lead atoms during close encounters, thus creating gold. Between 2015 and 2018, 86 billion gold atoms—about 29 picograms—were produced in this way, at a rate of 89,000 atoms per second.
