| Theory suggests that, at the moment the universe was created, equal amounts of matter and antimatter were formed. |
| When a particle or atom of antimatter comes into contact with a particle or atom of normal matter, both are annihilated and energy is released. |
| He saw how magnetic traps could make antimatter useful in medicine, principally in tumor treatment. |
| Those equations and present particle physics say that matter and antimatter are equivalent. |
| What is CP violation and how does it explain the fact that matter outnumbers antimatter in the universe? |
| Why is the universe made of matter and not equal parts of matter and antimatter? |
