sentence: Physicists find out about particles by studying collisions between different particles.
sentences_after: A good analogy of how physicists study particles through colliding is the car crash example. Imagine a person wanted to look inside cars. By crashing two cars together at very high speeds, we can break the cars apart and see inside. In the same way, physicists crash two particles together in order to break them and study the inside.
