| In general, the distinction between matter and antimatter is somewhat arbitrary. |
| This brief survey of recent Lorentz tests only lists those experiments involving light, ordinary matter, and antimatter. |
| What is CP violation and how does it explain the fact that matter outnumbers antimatter in the universe? |
| When particles of matter and particles of antimatter collide, large amounts of energy are produced as a by-product. |
| If it turns out that antimatter gravitates in any way different from matter, a whole lot of theory is going to have to be revised. |
| Why is the universe made of matter and not equal parts of matter and antimatter? |
