36 Facts About Large Hadron Collider (LHC)

What is the Large Hadron Collider?

The Large Hadron Collider (LHC) is the world's largest and most powerful particle accelerator. Situated at CERN, the European Organization for Nuclear Research, it has revolutionized our understanding of particle physics.

1. The LHC is located near Geneva, Switzerland, straddling the border between Switzerland and France.
2. It is housed in a circular tunnel 27 kilometers (17 miles) in circumference, buried about 100 meters (328 feet) underground.
3. The LHC was built to explore the fundamental particles that make up the universe and the forces that govern their interactions.

How Does the LHC Work?

Understanding the mechanics of the LHC can be complex, but breaking it down into simpler facts can help.

4. The LHC accelerates protons to nearly the speed of light before smashing them together.
5. Superconducting magnets guide and focus the proton beams along the circular path.
6. The LHC operates at extremely low temperatures, close to absolute zero (-271.3°C or -456.34°F), to maintain superconductivity.
7. The collisions produce temperatures over 100,000 times hotter than the center of the sun.

Discoveries Made by the LHC

The LHC has been instrumental in making groundbreaking discoveries in the field of particle physics.
