Hadron Collider
A giant machine that crashes super fast particles together, trying to figure out how the universe works. It’s buried deep in the ground and costs a ton of money.
The scientists spent a billion dollars on this machine just to see what happens when they crash tiny particles together.
This thing is so expensive and complicated that it’s like trying to build a spaceship with a bunch of glue and paper clips.
They built this underground in France and Switzerland just so they could avoid the embarrassment of not knowing what the hell they were doing.
