I was singing in the shower holding a near empty bottle of shampoo when I felt the vibrations on the bottle. Having a dumb moment I thought to myself "If only Daredevil could see vibrations, then it would be as though he could hear..." Then I realised I had it the wrong way round.
But another, less stupid thought popped into my head: "Can he feel/hear radiation pressure?"
Photons exert a pressure (however minute) on whatever they strike, so instead of waves of sound pressure causing a visual stimulus, a wave of radiation pressure would give an aural stimulus. It would however be very 'dim', as radiation pressure from a million red photons would be no more than 4.2 yoctopascals (10^10-24).
Is this possible for him? <joke>
Or should I go pitch this idea?</joke>
