Feynman Diagram Ecosystem
The Language of Particle Physics
You're watching a kinematic visualization of subatomic particle interactions, rendered in the visual language developed by Richard Feynman in 1948. While physicists use these diagrams as rigorous calculating devices for quantum probability amplitudes, this simulation dynamically visualizes the topological rules of the Standard Model—showing how particles can legally interact, transform, and decay.
Use the scenario selector at the top to switch between the random dynamic ecosystem and curated particle events like "Annihilation Burst" or "Cascade Decay".
Reading the Lines
Each line style has meaning: solid lines represent fermions (matter particles like electrons). Wavy lines are photons—the carriers of electromagnetic force. Coiled lines represent gluons, the strong force carriers. Dashed lines indicate massive bosons (W, Z, Higgs) that mediate weak interactions.
Vertices: Where Physics Happens
The bright flashes you see are interaction vertices—points where particles meet and transform. Each vertex represents a quantum interaction governed by the fundamental forces. The flash is a visual cue that physics is happening: a decay, an annihilation, or the birth of new particles.
