So, some facts and figures.
The LHC - Large Hadron Collider
(hadrons are composite particles - of which protons and neutrons are two examples. Always be careful when typing hadron not to get the d and r mixed by accident. Easy typo, completely different machine....)
26 659 m in circumference - the largest machine ever built
>10 years to build, and due to start this summer (first collisions predicted in August)
The magnets are kept at 1.9 degrees above absolute zero so they are colder than outer space. This is so they are superconducting.
This requires the world's largest fridge - >10,000 tonnes of liquid nitrogen.
This, combined with the detectors, will produce more than 800,000 GB of data every year and requires a whole new class of supercomputer to be designed to be able to handle it.
This of course is if it works as planned. We'll find that out later this summer.
