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 though 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^<sup>-24</sup>). Is this possible for him? `<joke>` Or should I go pitch this idea?`</joke>`
