> [@Asympotically\_fat](#): > > Nope mate, I’ve got 99 problems, but this ain’t one. Then enjoy not understanding what occurs physically in nature. If you ever do want to correctly understand what occurs physically in nature then understand the following. Aether has mass which is physically displaced by the particles of matter which exist in it and move through it. There is no such thing as non-baryonic dark matter anchored to matter. Matter moves through and displaces the aether. The Milky Way’s halo is the state of displacement of the aether. The Milky Way’s halo is curved spacetime. What is referred to geometrically as curved spacetime physically exists in nature as the state of displacement of the aether. A moving particle has an associated aether displacement wave. In a double slit experiment the particle travels through a single slit and the associated wave in the aether passes through both. ---

Heh well, I guess the joke’s on me for expecting any sort of answer. The problem with your intuitive concepts is that they’re often misleading; hence, the use of mathematics to make precise what is often obscured by intuition. ‘Many worlds’ don’t have anything to do with the mathematics—it’s a controversial interpretive superstructure tacked onto the math to get it to make more sense intuitively; but the mathematics itself is perfectly clear, in so far perfect agreement with observation, and unequivocally establishes that your babbling about the state of displacement of the ether is indeed nothing but babbling.

That’s fine. There’s nothing wrong with that. However, it is a waste of time. Are you trying to imply that’s like some sort of blind, uncritical faith? Like I said, you’re trying to overturn established scientific understanding. There’s nothing wrong with that, but don’t be surprised that you have to answer questions. If you’re in a huff about people ‘believing conventional wisdom’, you should certainly not expect people just to believe your hypothesis unless you explain it. > [@](#): > > For example, you believe particles of matter light years apart can wave.

I don’t know what you think occurs in a double slit experiment, however, if you believe particles of matter light years apart can wave it seems pretty obvious to me you are never going to understand it is the hidden medium of de Broglei’s wave mechanics which waves and that hidden medium is the aether.

Why are you wasting time badgering people on a message board about their reluctance to embrace your ideas instead of writing them up properly and submitting them to a journal? Just writing them up properly would be useful; you’ve mentioned time and time again here that aether is responsible for everything in electromagnetism, quantum mechanics, and general relativity, but you’ve never made any definitive predictions, any concrete statements about how aether interacts with other particles or forces (beyond vaguely ascribing every non-classical phenomenon to it), or any real specifics at all.
