Bubble chamber: Omega production and decay
This image is taken from one of CERN's bubble chambers and shows the decay of a positive kaon in flight. The decay products of this kaon can be seen spiraling in the magnetic field of the chamber. (Image: CERN)

The Big Bang should have created equal amounts of matter and antimatter. So why is there far more matter than antimatter in the universe?
