Physicist Peter Steinberg explains that fundamental particles like protons are themselves made up of still smaller particles called quarks. He discusses how new particles are produced when quarks are liberated from protons...a process that can be observed in Brookhaven Lab's Relativistic Heavy Ion Collider (RHIC).
If a universe explodes into existence, and no one is around to hear it, does it still make a sound? The answer, according to RHIC physicist John Cramer, is a resounding yes. You can listen to the reverberations the Big Bang sent ringing through the cosmos in a new sound file based on the cosmic microwave background that originated at the birth of time.
