      the speaker can't speak normally, she's so nervous her hands never stop moving the entire 18 minutes I've never seen someone butcher hand gestures the way this lady has, she flales her hands and arms for every single word. And I mean every single word... she is trying to use her hands to describe the words: and, the, it, universe, if, could, etc.
      It's irritating because I'm trying to engage and listen to the thoughts and ideas being conceptualized by her words and hand gestures but I can't. When someone doesn't not stop moving their arms around it is the equivalent of not moving them around at all, just at the other end of the spectrum...

    Think of it this way. To create waves in a kiddie pool, you can splash in the pool and have the waves travel from the point of splashing, or you can shake or distort the pool itself, and the water within will be disturbed.

    @Neylonx it's *mechanical* waves. it's just that the definition is quite simple and clear. to answer our question, there are mechanical waves at frequencies we cannot hear. i wasn't precise. but they are still mechanical waves. just like we can't see the entire electromagnetic spectrum, but we still call it "light". afaik there are no mechanical waves in the vacuum. so just as well we can create a program that reinterprets electromagnetic waves into sounds. reminds me of #1 quote from BSG.

    An Audio resonance that Vibrates the Ether and IS the very energy this Universe runs on. So powerful that this Resonance broadcasts to infinity and ever expanding. Light is a perturbation of the Ether. Created by a vocal Phrase. That one Phrase spoken all things into existence. All mater, energy, math, physics subject by that Voice. Subject to a resonance or vibration. A wave that flows by everything and Gravity is the affect of that flow of Audio passing all matter ever expanding. Like a buoy in the ocean of water affected by the current.
    Uni Verse....is the best description and is the most accurate explanation ....not just a definition.
    If you want to find the secrets of all things in this Universe. Study sound and resonance. One Voice spoke all things into existence and that Original Wave is traveling to infinity.

    @rick4318 are you sure about that? At the high vacuum that is in space, though there are particles, they don't interact the same way preassurized gasses do. Since there are no continous couplings that can sustain an oscillation of preassure, speaking of sound propagating through space is meaningless. A flow of particles with variating density is possible, but then there is no oscilation of preassure propagating between particles, and again is not sound.

Then if you have dark matter, the whole universe doesn't make sense anymore, so you invent dark energy, which again makes no sense, and so on
