Universal Sound

New Scientist is carrying this report summarizing a new way of thinking about the Big Bang. Instead of using visuals, one scientist has found that using sound conveys what happened more accurately. Anything that can make the early universe more comprehensible is fine by me.

Also includes the interesting revelation that sounds could be heard in the early universe. The cosmos was small enough and dense enough to allow sound wave to propagate, apparently at an appreciable percentage of the speed of light. Of course, it's my understanding that at that moment, the universe was so hot it still glowed completely white, so it's very doubtful that anything was around to hear the noise.

I guess that will answer what "the sound of one hand clapping" is.
