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 ??

Thanks again, Mandrake. Any idea how the sound was captured ? Obviously, it couldnt have been 'heard'. Must be an interpretation of visual confirmation (by way of X-rays / something else and model simulation) of the 'ripples' that the sound would have caused in the gas clouds over millions of years.
By compressing into 5 seconds, u mean the frequency of the original sound was increased to bring it into human hearing range ?
