Gravity is the missing link between QM and GR. Matter Waves do not have gravity, do not age, and are not physical. Spacetime(gravity/age/physicality/local/phase velocity) is assigned via decoherence.
The quantum/classical boundary is the mass of 0.3 micrometers because gravity can't be automatically assigned below that (objects above this line are automatically decohered) and because that is the width it takes light to travel in one femtosecond. 0.3 micrometers isn't a unit of mass, but it is the width an object would be that has the right amount of mass.
Duality at the same instance is not a thing. A particle/wave will be one or the other for its path from A to B. What matters is if a particle will decohere in its flight. A dead stop isn't decoherence, that is wave collapse. Wave collapse does not influence what a particle will be in its flight. It's possible for a wave to make it from point A to B without being measured before the final screen. That's why it shows fringes. You don't get quantum weirdness (Superposition (not talking about superposition of states), Entanglement, Tunneling) events when it's a physical particle. They don't experience weirdness after decoherence. Only cohered waves are allowed weirdness events.

Entangled waves become physical particles at the same moment with decoherence. If they are to be physical in flight, they will be so from the beginning, no midair swaps. A measurement far after the double slit experiment shows this. Future observed matter-waves decohere before they start moving because their momentum direction triggers decoherence. (Decay of coherence)

The quantum field doesn't use the full dimension of time (or gravity) from spacetime. It doesn't have a forward time limit for being influenced by physical states (spacetime). This is the core of what measurement/observation is.

You don't use a wave function for a physical particle

A particle gets reflected by a potential well if I can describe the particle mathematically without the wave function. Duality has been assumed during physical particle flights because they can take the path of diffraction ..but that path is guided/influenced by the quantum field ..not that the particle itself is a wave.

This is the gateway to the Unified Theory. Physical particles go with GR, Unobserved Quantum Waves go with the Quantum Field. Spacetime is separate from the Quantum Field.

The Quantum Field and Spacetime are two separate realms. The Schrödinger equation is assuming the coordinates are in spacetime. The quantum field has all the properties needed to propagate a wave without spacetime. Space isn't expanding in cosmic voids beyond the Local Group, the quantum field is. Spacetime doesn't stretch/expand ..it only bends. Spacetime is everywhere, but it is not enacted everywhere. Decohered mass enacts it. We know it is not enacted everywhere because unobserved quantum waves can complete their journeys without being observed(fringes). It seems when space doesn't have mass in a region ..spacetimes' influence diminishes. Spacetime isn't bent in voids.

Nothing is physical without spacetime.

Uncertainty is a quantum field property. It is built into a scattering matrix to solve a physical particles diffraction path. So uncertainty can influence an observed particles trajectory, but it can't help it tunnel because the particle is not a wave. Dirac interaction picture in nLab

No, you don't get to say that anymore. I provided a link to a physical particle not using the wave function. In doing so, it shows observed particles can not partake in quantum weirdness events because they are required to be waves to do so.

Yes, he gets to say that. These two sentences are complete rubbish. First, GR is gravity so it can't be a link between GR and QM. Second if matter waves have mass then they "have" gravity. (In fact, all particles create a gravitational field, massless or otherwise.)

And that's just the first two sentences!

So, "word salad and nonsense" is indeed an appropriate description. As we've said many times before get off the computer and read a textbook.

Yes, GR has the property of gravity, unobserved matter ways do not show hints of gravity, observed particles do.

Have you attempted to do anything with a decohered wave with the wave function? It doesn’t work, the wave functions cancel each other out leaving a single state. Quantum weirdness events, mathematically, do not occur with decohered waves.

You can’t send a decohered wave into a finite potential well, or a reflection equation. Uncertainty doesn’t belong with physical particles, that characteristic belongs to the quantum field. A decohered wave is not a wave, it is a physical object.

You see, this is why you need to learn something. Unobserved matter waves do have gravitational effects. The calculations are not usually done because the gravitational fields are very weak. On the other hand we usually ignore them for observed particles as well.

This is why I usually don't answer anything anymore because you simply won't learn from what you are being told.

Once again, I'm out.

Wow, you are very sure of yourself. Please show me unobserved matter waves displaying gravity.

Yes, I am confident. I only have a degree in the topic...

Here's a Feynman diagram for a $$\displaystyle \Delta ^{-}$$ decaying to a virtual graviton (the wavy line) and a vitual $$\displaystyle \Delta ^{-}$$ then recombining into a $$\displaystyle \Delta ^{-}$$. (We may insert this diagram into any $$\displaystyle \Delta ^{-}$$ line in a larger diagram.)

1) According to you this diagram can't exist because the virtual $$\displaystyle \Delta$$ can't absorb a graviton. Please show me the calculation that shows that the amplitude for this diagram is zero.

2) This is a diagram for a vitual process so we don't actually see the graviton emission. However, even though the process cannot be directly observed, it has a measurable effect. What is that effect?

3) Here's an extra challenge. Why am I using a virtual $$\displaystyle \Delta ^{-}$$ here instead of, say, a virtual electron?

If you can answer these questions then we can continue this discussion. If you can't then you don't understand the concept well enough to tell me I don't know what I'm talking about.

Graviton is not a thing, I wanted actual experimental evidence ..not misguided math
