How Do You Slash Protons Together?

The universe is filled with huge particle accelerators that are throwing particles at us. We push the protons really hard with electric fields and then we bend them with magnets so they go around in a circle. So that's one of the fastest collisions that we know about as scientists in the universe. But it actually doesn't even compete with what the universe is already doing all the time. There are things in the universe smashing close to each other faster than twice the speed of light.
