like lasers in starwars wouldn't have the sounds since its a vacuum,
this I can get behind
But when he talks about the scene in back to the future where the
massive speaker knocks alex p Keaton backward I have to take umbrage.
I always equated the pressure waves from speakers with the soundwaves,
but since realized its the motion over the speaker creating a pressure
wave.
But now I'm reading a sound wave itself cant do much to move an object.
This is just bothering me
next somebody is going to tell me that the quarters under my pillow
after I have a tooth pulled are just magically appearing there and
there is no tooth fairy (yeah right)
