Help!! Particle accelerators I want to know what particle accelerators do but can't seem to find anything anywhere! I've been searching everywhere, but the answers are very vague. My question is what do particle accelerators tell us about the structure/ behaviour matter? How do they do this? I've seen answer like 'they disrupt the nucleus and act as a probe' etc, but i still don't get HOW this disruption will explain anything about the structure/behaviour of matter Please help, i've got an assignment due and i'm stressing out!! Thanks in advanced.
