Sonoluminescence - Wikipedia, the free encyclopedia Only just found out about this, naturally the first sweeping conclusion that any layman would jump to is that one of the main theories about the universe' creation is from a bubble, the release of heat and light indicate a mini explosion of some sorts. So we're all in an immense sea? I wonder where the photon comes from? Some further info: Also, I wonder if this cavitation effect and tiny bubbles cause any light emission for ships or subs? The Sonar might cause solarwotchacallit from prop bubbles. Tho I imagine the designers are aware of this as the RN discovered it in the first place.
