Queries On Universal Nature, Or Nature of the Universe :smile: Options

This is in response to a post at the Shlokas thread -- Gayatri Mantra

Can sound (as we know it) be generated in space ?? Theres no (known) medium between the fast moving bodies for sound travel. Else we'd all have evolved as deaf creatures, or probably developed an alternate way to understand sound amidst all the terrible (and terrific) background noise.

Is energy created in the universe (apart from E=mc^2) ? The kinetic energy of galaxies is simply the energy they possess due to their motion. If they stopped moving, all the KE would be transformed into some form of potential energy, I believe. (Although that might lead the collpase of galaxies due to intense gravitational fields). And where is the sink (if any) where energy is consumed ??

That the universe generates sound had been a known fact. This was corroborated when astronomer Mark Whittle (I find that a remarkable concidence for the similarity to 'Vitthal' ), who prepared a sound clip way back in 2004 and called it the 'Primal Scream'.
He describes the sound as "...a growing hiss that resembles a roaring jet plane flying low overhead. "
