I'll take it one by one.Oh wow, you are actually reading my posts. Okay, yes, you did read it right. I figured out that the fabric of spacetime and the quantum field live in the temporal dimension. I hate to break it to you that there is, indeed, a quantum/classical boundary. It is around the mass-energy value of a virus. If a particle smaller than a virus plans to decohere in its path from point A to B ..the virtual fabric will oblige, and consider it real, physical. Gravity isn't a force, it is the shape of the virtual fabric.

The quantum field doesn't live in any space-time dimension, it lives in a subpace of Hilbert space. (Hilbert space is an infinite dimensional (complex) space. Think of an infinte verson of normal 3D space and you won't be too far off.) Generally speaking this is why we can't measure the properties of the wavefunction directly.I figured out that the fabric of spacetime and the quantum field live in the temporal dimension.

Since you told me once you were suspicious about the Math involved how did you calculate this?It is around the mass-energy value of a virus. If a particle smaller than a virus...

Strictly speaking coherent waves are only defined in terms of the Quantum harmonic oscillator. But I can't see any reason why we can't fudge the concept a bit. But why would the state decohere? Once it's in that state the time evolution of the wave function would not change, which is the value of using a coherent state to begin with.... plans to decohere in its path from point A to B

You have a great deal of fascination over virtual (or as you would say unobserved) fields. All a virtual particle is is an unobserved state. It still has its spin state, electric charge, etc. The momentum of a virtual particle can be different than its observed value if it is in a particle loop in a Feynman diagram. There we have to integrate over all possible momenta. A virtual particle that does not have the same mass as an observed one is said to be "off its mass shell."..the virtual fabric will oblige, and consider it real, physical.

Also, virtual particles

*are*real. They just haven't been measured. Unless you are using the word "real" to mean that the virtual particle lives in some kind of complex space? This is correct. But all particles live there. You couldn't say that the particle "becomes real" since it still lives in the complex space.

Many think that way. I'm sort of sitting on the fence about it. Do the Einstein field equations describe an actual bending of space-time or does it just mimic that bending and be something else entirely? No one has got proof of either argument.Gravity isn't a force, it is the shape of the virtual fabric.
