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 momment 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. https://ncatlab.org/nlab/show/Dirac+interaction+picture

Waves have peaks and valleys therefore they are subject to gravity accordingly to their atomic orbits.

#### pittsburghjoe

What? We have nothing to show unobserved waves are influenced by gravity.

#### Ront5353

"Waves do not have gravity ", waves have flat nodes between oscillations of highs and lows. Oscillations of high and low are a result of kinetic energy proven by mathematical structures and observations in the lab. Space and time have two different symmetries and fields both can be quantized both are separate entities but both exist together. Gravity is a by product of kinetic energy of an atomic orbit of mass. The less spin the less energy less gravitation is involved.

#### pittsburghjoe

weak force and strong force handle orbitals

..are you high or a nut?

#### Ront5353

I don't believe in metaphysical aspirations everything can be quantized.

#### Ront5353

Time-dependent Schrödinger equation particles can tunnel dependent on the energy and the barrier.

The thing that has no physicality is mathematics. We have a science of mathematical relationship, not knowledge.

Just duplicating or verifying a relationship, is not proof of knowledge or understanding. At least for me. I have higher standards.

Using the non physical to explain the physical. I would define that as religion.

Science now promotes, what it has long denied.

For energy eigenstates we define <n|m>=kroneker-delta(n,m).
For some n, <n|n>=0 for n=0.

I think we are going to discover n also implies it equals spin 0
or if an energy eigenstate = 0 then so does its spin

The ground state electron will NOT have a spin half ..decohered waves all have spin 0 from start to end.

This means Physicality is a new branch of QM.

I think wave collapse is what triggers other types of spin. Physical particles might not have a wave collapse event.

There is something very fitting about the higgs being a spin 0

Decoherence has been used to understand the collapse of the wave function in quantum mechanics. Decoherence does not generate actual wave-function collapse. It only provides an explanation for apparent wave-function collapse, as the quantum nature of the system "leaks" into the environment. That is, components of the wave function are decoupled from a coherent system and acquire phases from their immediate surroundings. A total superposition of the global or universal wavefunction still exists (and remains coherent at the global level), but its ultimate fate remains an interpretational issue. Specifically, decoherence does not attempt to explain the measurement problem. Rather, decoherence provides an explanation for the transition of the system to a mixture of states that seem to correspond to those states observers perceive. Moreover, our observation tells us that this mixture looks like a proper quantum ensemble in a measurement situation, as we observe that measurements lead to the "realization" of precisely one state in the "ensemble".

Decoherence was first introduced in 1970 by the German physicist H. Dieter Zeh and has been a subject of active research since the 1980s. Decoherence has been developed into a complete framework, but it does not solve the measurement problem, as the founders of decoherence theory admit in their seminal papers

It's as if you didn't read anything I wrote, please don't come back.

#### Ront5353

Free country, I read what you wrote. You use the word decoherence so I looked it up. It appears there is no validity . Just curious.

#### pittsburghjoe

Have we tested an unobserved matter wave without a vacuum? No light, but let there be air in it. I don't think decoherence is very fragile to other free particles that are not light. It explains how tunneling can happen in our bodies.

#### Ront5353

Philosophical argument against general covariance: general relativity only determines a diffeomorphism equivalence class of metrics; if stress-energy is known outside some region (hole), there is a solution of GR with known values inside the hole . Your discussing a philosophical argument?

#### pittsburghjoe

Is decoherence, entanglement with the particles future self that is being triggered to use spacetime (become physical)? A wave that doesn’t experience decoherence in its path becomes physical at the end with wave collapse.

#### pittsburghjoe

Can quantum entanglement be instantly possible across the whole universe?

Yes, the quantum field doesn’t care about distance. It doesn’t use the spatial dimensions of spacetime. Entanglement is a wave only activity. The particles are not real/physical until measured. The quantum field sees entanglement as a single entity. After measurement, they are not waves anymore. The wave has been split in two. This is why one gets the opposite spin as the other.

I think entanglement has a new aspect to it that we didn't know about. To answer the measurement problem, is it necessary to consider a particle can be entangled with its future self?

The quantum field doesn’t have restrictions on future time for decoherence events. Information isn’t being sent, only state. This is all happening with a single wave. Entanglement is seen as a single wave to the Quantum Field. The decoherence event is tapping the front of the wave to be physical at the start of it. Think of it more like how a wave that just went through both slits of a double slit experiment is entangled with itself.

#### Ront5353

For entanglement to occur you have to have two particles that are attracted to each other requiring two different waves. Decoherence is a philosophical event that may or may not occur.
