Particles Zone

All matter is made up of particles, and there are many types of particle. There are atoms which in themselves are incredibly small. An atom contains protons, neutrons, and electrons; which are also particles. Protons, and neutrons are made of quarks, now we’re looking at very small particles indeed; a quark is smaller than 10-19 m across (that’s just 0.000 000 000 000 000 000 1 m). Quarks are subatomic particles, which also include leptons and bosons — we’ve all heard of the Higgs boson.

In this zone is a scientist using very large computers to work out what happens to particles when black holes merge, and a scientist trying to make sense of nature by colliding protons against each other at the Large Hadron Collider. There’s a scientist developing precise methods to the forces between particles, and another trying to understand what happens when particles are smashed into each other at very high speeds.
