Particle Physics

Dive into the fundamental building blocks of realitywhere quarks dance, bosons mediate, and the very fabric of existence unfolds at the smallest scales

Standard Model

What is Particle Physics?

It is the science of the invisible a search for the hidden architecture of reality. In this realm, matter dissolves into quanta, forces whisper across emptiness, and observation itself becomes a disturbance. Particle physics asks not just what the universe is made of, but why it behaves so strangely when we try to look too closely.

From the moment we uncovered the electron, reality began to shift. The Higgs boson only confirmed it that beneath the world we know lies another, colder and stranger, waiting to be understood.

The Standard Model

The Standard Model of particle physics describes the fundamental particles and three of the four known fundamental forces in the universe.

When Particles Collide… and Never Let Go

At CERN’s Large Hadron Collider, particles are smashed together at nearly the speed of light to recreate the conditions just after the Big Bang. These collisions reveal short-lived particles and fundamental forces, helping physicists decode the very fabric of the universe.

Interactive Particle Detection Methods(Beta)

Bubble Chamber Simulation

Liquid heated near boiling point. When a charged particle passes through, it ionizes atoms, creating nucleation sites where bubbles form along the particle's path.

How It Works:

• Liquid is kept just below boiling point under pressure

• Charged particles ionize atoms, creating nucleation sites

• Pressure is suddenly reduced, causing bubbles to form at ionization points

• Camera captures bubble trails before they obscure the chamber
