Gravity as ratio
Let me take you on a short walk.
Mass is motion:
1. Detect a stable particle that is stationary, it is in place P1. Detect it again, it is in place P2. Ergo it has moved. It really did move, you did not "collapse a wave function by measuring it", the particle doesn't know which interactions constitute 'measuring' anyway and it is constantly interacting with the universe, so it would be constantly being detected. It really is moving, yet overall it is not in motion, it was a stationary particle remember? So those movements must cancel out. Ergo it is doing some sort of oscillatory motion.
2. The same must be true of the electrons in our detection circuit, so they are also doing an oscillatory motion, so electric is an oscillating force. Magnetic has a fixed relationship to electric, so magnetic also must be an oscillating force.
3. You never detect a particle, you only detect the net effect of the oscillating force to the particle. All those weird effects, like particles travelling backwards in time? No, they're no different than the spokes of a bike turning backwards when recorded on video. The net effect of a slight differences between the shutter speed and the wheel speed. Here the slight difference between the oscillating electric field you're measuring with and the oscillating particle.
4. If you had a slightly different oscillating field from your detector, then your particle would be in motion over that field. It's only stationary with respect to a particular observer with a particular oscillating field. In the bike analogy, the wheel is stationary, but if I change the shutter speed on the camera, then it is moving. The particles motion is not a function solely of itself, it is a function of the net effect of the oscillating electric field from the observer and the oscillations of itself.
The motion is with respect to a given observer. Hence ALL MOTION IS THIS MOTION. Every form of motion you've ever detected is this motion. Velocity, spin, the weird oscillatory motion of light, the orbit of planets and movement of stars, all is the net effect of the oscillation modes of the matter in your detector vs the oscillation of the particle.
The velocity of those stars is the same motion that is there at the subatomic level, because it is the ONLY mechanism of motion.
5. Point 4 is true all the way up to the [zero mass/speed of light] limit case. Light is moving the same way. It moves the same way through the vacuum between atoms of glass as it does through the vacuum between atoms of gas, as it does moving between atoms of really low density gas, all the way to a vacuum, at no time does it move any other way. Always near 1 resonant oscillation of the local field.
6. And since the size of a particle is from its the extent of this motion, hence the *scale* of space is also from this motion. Light moves N electrons in M oscillations of this resonance field, this is true regardless of N. N could be 1 in one direction and 100 in another, and it would still be true. We measure lights speed by comparing it against matter, and since light and matter both get their scale/speed from the field, so the speed of light in a vacuum always appears to be a constant when compared to matter. The apparent constant, "speed of light in a vacuum" isn't a constant, its just a fixed ration we chose when we chose our unit of time.
OK, so we almost got mass here, you have a) a motion that goes nowhere that can be converted into movement, but you also need a clumping force, gravity. Mass has gravity, not just an energy that can be converted into motion.
7. Take a bunch of magnets, shake them up, they end up clumped. Why? Because the repel ends push apart, the attract ends pull together and there is a net clumping effect. They organize themselves to clump.
8. The same is true of oscillating forces. Notice how things will try to settle to resonance? And the ability to clump is a function of the component of overlap of the two oscillations, stationary mass clumps with stationary mass at the same velocity because it is oscillating the same way and hence maximum overlapping oscillation component.
The overlapping oscillation clumps the most, light clumps with light.... ~same oscillation mode. Matter doesn't clump with light... ~zero overlapping component, stationary matter clumps with stationary matter ~same oscillation mode.
9. If you have a clumping universe, and clumping planets, then both the planets are clumping together AND SO IS SPACE, and you observe it as the ratio of the two. That tiny clumping effect only *appears* to be tiny with respect to the matter clumping. See wabbit347 comment above....
Can I point out:
You might want to realize that to be stationary and in resonance, it must return to the same place after an *Integer* number of resonant oscillations and given this is mass, you might then realize the ~ near integer atomic masses of stationary/stable atoms is a consequence, not accidental. You might also then notice that non-stable (i.e. non-integer) particles are not stationary when in an even field, and you might then explore pushing an oscillating particle with an oscillating force and realize that you're not making mass, it's just harder to push....
