Particle tracks and cosmology. Computer illustrat- ion of subatomic particle tracks (red) on an historical star chart. The particles are seen as coloured points. The tracks result from charged particles moving through a bubble chamber containing a superheated liquid. Ionisation of the liquid by the particles causes it to boil,so that tracks of minute bubbles are left in their wake. Each particle creates a distinct track,such as the spirals of electrons and positrons. Particle physics has revealed the basic structure of the atoms that form the universe | |
