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 ??

Vivek, by compression to 5 seconds means that the sound data over 1 million years has been compressed to 5 seconds. Obviously, the 'notes', as they are heard here were formed verrry slowly. When compressed, they give one continuous sound like the jet.

And yes, the sound is a conversion of the cosmic microwave background radiation.

Also brings another thing to mind: way back in 1979, I had read in the newspapers that sound waves don't die away totally. They go to a ultra-micro state and remain so. The hypothesis went so far as to ponder, whether we could eventually develop a technology to 'reconstruct' those sounds, and listen to all that happened in the past, "provided we also developed the technique to zero in on specific strands of conversation".
