the emotions of a cosmos cannot simply be put down to sound
but frankly theoretically sound wave strings are a logical conclusion..
as are bubles of pure thought traveling within multipe dimensions both up and down at the same time...
across a metamorphic sphere
other reasonable theories exist but non are mine like the last 3 :)
simply state the universe is recursive symbolic poetry ,
one can interpreter it many ways for it is beyond one simple understanding,
to think one understands the universe is to understand that you are a fool to have simply not admitted it was a wonder.. ;-)
