Thank you very much for that well thought out explanation.
Is there any way you can prove these statements wrong, or give me reasons as to why they are not most likely:
The Heisenberg uncertainty principle, is not a description of reality; that is to say, it is a wave function equation that does not perfectly and absolutely embody the existence of particle/wave of reality, thus it is not to say that a particle or wave of energy behaves in a superposed state and it does not have an exact location and momentum. But that the uncertainty principle is only a human made tool, that is our best yet form of 'wrangling' bits and areas of nature, into the neatest and tidiest ways of measuring it, and predicting it? An analogy of the question I am asking is, the uncertainty principle relating to a stick figure drawing made by a 10 year old of the most details of the mile radius surrounding his childhood home, and then referring to it as reality in an argument, and then me saying, but dont you mean that that stick figure of your mom and dad is an approximation, your best yet, of a truer more viable reality? And the 10 year old saying, no according to my stick figure drawing this is what my mom and dad are.
The other statement I want to make and for you to try and prove wrong, or not most likely:
When 'entanglement' occurs, what really occurs, is 2 separate particles being created, that are not 'entangled' in any way, but merely have inherently, do to the event which created them, opposite characteristics, so that when either is measured, it is discovered that the other has its opposite characteristic. This is to say, if we imagine a quarter, a pre 'entanglement' event particle, and then we split the quarter and create 2 'entangled quarters', when we measure one and discover that it is heads, instantaneously! it signals the other side to make sure that it transforms into tails.

The EM field enters through the stress-energy tensor which sums up contributions from material particles, pressure, and electromagentic fields. It's not quite right to say that the EM field has mass, though it does have an energy density and momentum flux, but more correct to say that gravitation responds to a sum of mass plus other stuff. In practical quantitative terms, mass dominates the other stuff in almost all cases (other than maybe cosmology).

Because your "skepticism" and intuitive assumption of "what can make stuff move" is completely influenced by our evolutionary biology and practical observations of the classical limit that dominates nearly everything that we do or observe, in which case our assumptions work.

Both statements are wrong, if i understand you correctly.
I interpret it as if you want to know if the uncertainty principle is just a limitation to what we can find out about a system or if it is a limitation in the system itself.
In essence, what Heisenberg's uncertainty principle says is that the more you know about a particle's position, the less you know about it's velocity (speed and direction). This seems to imply that you just can't measure the two at the same time, but that is not the whole truth. Simply put, the particle can't have a well-defined velocity if it's position is known precisely.
You could see this as the very reason why particles behave as waves, or conversely as a consequence of the wave nature. It's hard to prove this to you in writing, but I can assure you there are experiments that you can perform which proves it. For example, if you shoot electrons at a tiny hole in a wall and detect them on the other side, you will find that they spread out. This can be interpreted in regards of Heisenberg's uncertainty principle, since what you do when passing the particles through a hole is to restrict their vertical and horizontal position to be within a small zone, which makes their velocities spread out. This is exactly how waves behave, so this is equivalent to their wave nature.
This statement was really the point of the entanglement analogy I gave earlier. No, it can't be described as two particles with opposite characteristics due to the event that created them, just like Alice and Bob can't agree on opposite answers before being questioned.

Tell me an unintuitive example of 'what can make stuff move', making something move, please. And just, im not asking for a lot, your thoughts in a few simple sentences, some background, on how and why, it is possible, for the example you will provide, to occur. What establishments and truths of nature, physical/material, or not, allow this to occur, and force it to occur.

In an average and arbitrary volume of space, does there exist EM field and gravity field? Do they exist entwined around one another, over lapping on top of each other? Are they stuck together like a + to - attraction and its just a really dense lattice of gravity and EM field all throughout space?
Knowing that light follows the curve/geometry of gravitated space, and that light is known to not have rest mass, is it possible that light does not create gravity, but just obeys the topography of the local gravity field?

Possible but would violate general relativity. I'm not sure about the status of the experimental confirmation, but I would never bet against Einstein. I'm not an expert on the theoretical motivations for sure but I have an idea. If you consider that electromagnetic interactions with particles can transfer energy and momentum back and forth from particles to EM fields, if only part of those gravitated and the others didn't, you'd probably end up with violations of conservation laws which aren't observed. Or you'd have a trick to make warp drive.

This is the statement I was replying to. I took it to mean, since I was claiming like Einstein, no spooky action at a distance, which we are quite familiar with the classical world, I took you to say there is a lot of spooky action at a distance possible in QM. I was asking, what an example of how this can exist is? I do not believe spooky action/entanglement is real phenomenon.
What is your evidence that 'entanglement' is not due to my rhetoric in an above discussion; a particle being split into 2 distinct particles of opposite qualities/characteristics...no spooky communication across infinite distance, no superposition and suspended state until observed? What is one, or a few if you would like, reasons why my view on that is not the possible reality?

I do, because the experiments keep on telling us so, and we don't have any better explanation beyond quantum mechanics.

Animals communicate with pheromones and that seems a factor in what is referred to as telepathy. In other words due to the complexity of the brain we are able to express more complex ideas than animals are able to in this way.
In and of itself though I feel it is important to point out that humans as a whole. Seem to experience some strange sensation, when certain metal objects are placed 2 cm from their foreheads.
There is no scientific documentation in existence that seems to explain why this is happening. Myself I was brought up understanding this experience so have had plenty of time to engage in samplings. It is really simple to do; place the copper top of a number 2 pencil about 2cm from your forehead, then consider why you are having that experience.
Perhaps the Universe is an phenomenon inherent to a larger system like a rainbow is inherent to a thunderstorm.
Any thoughts?

I just dont think it can be true, that a quanta of energy or material can be said to exist at all, but not exist.... Saying that it does not exist in an exact location in and of itself at all times, is equal to saying it does not exist at all. Same with the velocity. I propose that (if the universe is real, and not a video game or gods computation of some kind) then if humans existed or not, or observed or not quanta of energy or matter, they always have exact velocities and locations.

Yes im familiar with the double slit experiment, if thats what you were referring too, I dont think its sufficient enough evidence to believe that uncertainty principle is an exact but symbolic (symbolic meaning, made of math, not a particle) replica of reality.
So is there such thing as 1 electron? And then there is such thing as 2 electrons? And this thing that is called an electron is not composed of parts, but a pure 'area/volume' of electron substance? And this electron moves linearly through time and space in and up and down pattern, which is its wave like nature? Or the physical 'area/volume' of the electron itself, is vibrating up and down like a wave? In the same way a jump rope is 1 physical area of rope, and it itself can move in a wave like manner.

Yes sorry, I admit I did not grasp your examples with the questions and Alive and Bob. But I still dont see how my expression can be proved false. Every time entangled particles are observed, they are always found to be opposite characteristics, yes? Noone knows what the characteristics of either are before they are observed, yes? Then my expression seems the most logical conclusion, and I have never seen anything that should warrant me to 'believe' otherwise.

Well, for all intents and purposes, they don't have exact positions and velocities. If they did, the universe as we know it wouldn't exist. Atoms would collapse, for instance. The very existence of atoms verifies quantum mechanics.
I really don't see how this would make the particle any less real. It's still there, it's just smeared out a bit.
The thing is, they're not always opposite. Sometimes they're equal, and sometimes there's no relation at all; and this depends on how you measure. Because of this dependence on how they are measured, it is possible to show that there is absolutely no way to pre-determine answers that give the results you get. It is evident that one's properties depends on how the other was measured.
I do understand the skepticism though. It's not an easy thing to just accept on blind faith, and it requires a lot of work to verify it for oneself. The thing is, when you understand it, you also see how impossible it is to explain it any other way.
You don't even need quantum theory to prove that entanglement is real and that there actually is 'spooky action at a distance' going on. You only need to do the measurements and apply some statistics and you'll find that the results are impossible unless we acknowledge that the particles are entangled.

Of course they have exact positions and velocities! We dont know them. We cant know them. But they have them...they are them.
To say an electron is orbiting an atom, or creating an electron cloud around an atom, is to say, an electron exists. To say an electron exists, and is orbiting an atom, or creating an electron cloud around an atom, is to say that the electron is always in its exact position, an electron in your eye right now is not on the moon, its not on the sun, its not in the galaxy over, or the galaxy beyond that, and its velocity is not an exact ~.000001 - 9999999 miles an hour. It is more then likely, definite in my opion or at least approaching certainty, that the electron by nature of being something that exists and is not nothing, is always traveling at a definite velocity, it would be silly, meaningless, and wrong to exclaim that an electron is traveling but not at a velocity. Sure it may change its velocity, it may change its velocity 100 times a second for its entire existence, or more so, have its velocity changed by surrounding circumstances, but its still always traveling a particular velocity. A car may change its velocity, a car on a 100 mile drive you may ask, what is that cars velocity, i can say, well it doesnt have a definite velocity, why because it changed throughout its travel, yes, well I propose at all times from start to finish the car was traveling exact velocities.
The thing is, they're not always opposite. Sometimes they're equal, and sometimes there's no relation at all; and this depends on how you measure. Because of this dependence on how they are measured, it is possible to show that there is absolutely no way to pre-determine answers that give the results you get. It is evident that one's properties depends on how the other was measured.
Well if they are equal, then can it be said they were not entangled, the experiment failed to produce 'entangled particles'? Same thing can be said if there is no relation at all? If both particles are measured and found to be equal, or both particles are measured and found to be un related, in what way would they say to be 'entangled'?
I do understand the skepticism though. It's not an easy thing to just accept on blind faith, and it requires a lot of work to verify it for oneself. The thing is, when you understand it, you also see how impossible it is to explain it any other way.

You still have not simply prove my hypothesis wrong; When 'entangled' particles are created (I will call them sibling particles, brother and sister) they are 2 exact particles that have opposite characteristics. What aspect of experimentation proves my interpretation incorrect?
If we had two bags, one with a blue ball in it and one with a red ball in it. You are saying before one of us looks in our bag, your bag contains a blue/red ball and my bag contains a blue/red ball, and then when you look in your bag and see that it is a red ball, faster then the speed of light your red ball signals my blue/red ball to turn blue, which what do you know, when I look in my bag, its a blue ball.

I am impressed by the issue of the Strange Quark with respect to its activity as a part of the proton. It constitutes 1 percent of the mass of an atom. But if as a virtual particle it would stop appearing in the atom, the atom would dissolve.
What if 1% of a Virtual Strange Quark would cease to exist in hypothesis; would that result in an atom dissolving?
What about 1% of 1% of a Virtual Strange Quark ceasing to exist, does the atom dissolve??
Is the change in mass enough to cause the atom to be disrupted?
Any thoughts?
