Take a look at some quick facts about the project:

• 20-year work-in-progress;
• A team of 7,000 physicists from more than 80 nations;
• 27 kilometers in circumference, 175 meters underground;
• Each tunnel is big enough to run a train through it;
• Temperatures generated: more than 1000,000 times hotter than the sun’s core;
• Superconducting magnets are cooled to a temperature colder than in deep space.
