What happens to sound waves from their point of origin?
It is my belief, that sound traveling in waves is absorbed by the medium through which it travels. Since electrons in atoms are always moving, the energy created by the sound source, is absorbed into the fuzz of electrons in atoms which the wave tranfers energy to. In the end... Sound lasts forever, but is lost in the buzz of existence itself; hidden from our perception but somehow leaving a permanent imprint in reality for eternity!!!
