as always i really like to read your sharp way of pointing out the ongoing spiritual crime against human beings. it is so refreshing.

well, from a sound engineer's standpoint, human hearing is said to go down to about 20 hz (meaning 20 wavecycles per second). but anything around that range and lower starts to become inaudbile to the ears and instead becomes sensable in the body. this low bass from a big speaker systems can be felt in the gut and the skin.

i think of the ominous shumann resonance of the earth which is said to be somewhere around 6hz. but theoretically anything above 0hz can be a cycling wave.

some proponents of rather esoteric standpoints have claimed that if frequency slows down enough, these waves become matter. from that standpoint anything can be seen a as cycling wave. matter being the lowest, going up to low bass which is sensable, then hearing, then seeing, then up into the electromagnetic spectrum to radio waves, microwave radiation and so on.

it really is hard to tell which phenomena are naturally occurring and which are manmade but officially denied.
