Particle Physics

Understand fundamental particles

Dark Matter

Dark matter makes up about 85% of the matter in the universe, yet we can’t see it or touch it. Discover the evidence for dark matter: galaxy rotation curves, gravitational lensing, and the cosmic web. What dark matter might be made of, from WIMPs to axions to other exotic particles.

Antimatter

Welcome to the world of antimatter — particles that mirror our own but annihilate on contact with normal matter. It’s rare, it’s powerful, and we can actually create it in laboratories on Earth.

Neutrino Oscillations

Trillions of particles are passing through your body right now… and you’ll never feel a thing. These are neutrinos — the ghost particles of the universe. They barely interact with matter, they travel close to the speed of light, and they have a trick that shocked the scientific world:

Quantum Tunneling

What if particles could pass through walls? Welcome to the mind-bending world of quantum tunneling — a phenomenon where particles defy classical physics and appear where they shouldn’t.
