Might the entire universe be treated as a single quantum wavefunction?

Recommended Posts

Could the entire universe be considered as having a single quantum mechanical wave function?
At the time of the Big Bang the universe was extremely small, of dimensions in which quantum phenomena were dominant compared to gravity, as the entire universe was smaller than a proton.
As the universe expanded, matter filled a much larger region, but particles whose wave functions were entangled would have remain entangled. A textbook analogy would be what happens when two elections with equal but opposite momentum are emitted from a source.  The resultant particles can become separated by the size of the universe, but their total wave function won’t collapse from its range of probabilities until a measurement is made determining the properties of one of the electrons, such as its position and its direction of spin.

Likewise as the universe expands, would its properties such as the total amount of matter, dark energy, etc. be probabilistic unless some observation could be made of the universe as a whole that would measure that property?

And would the measurement of that property result in the quantum wave function for the entire universe collapsing to yield a single resultant measurement as happens when a measurement is made on an election as described above?

This above questions are related to the issue of whether our universe is really one possible universe in a manifold of universes that would make up a multiverse.

Oh, ya, I Think it does have a Dimensional frequency in a dimensionless form which would be the certain state this universe is in compared to other universes.

I actually have a version of this in my model.

(Universe Volumetric Planck State @ size of universe in radius) =(3/4)π ((RUniverse/(tpC)) Luniverse )3

Luniverse = (Charge,∇Color,∇flavour,∇gravity  - ∇Dark Energy)

charge possible states per point (1,2/3, 1/3, 0,-1/3,-2/3,-1)

Color Possible states per point(R,B,G,0,G,B,R)

Flavour possible states per point (I,II,III,0,III,II,I)

Gravity/Dark Energy possible states per point of space (Energy,Mass,Spin,0,Energy,mass,spin)

If you were to construct it, it would look something like this.

Per point in the universe to planck length  Lp  or TpC = L or each cube in that sphere has 5 values.

Your model is not the topic here. Replies should be mainstream physics, or questions regarding clarification.

The Wheeler-deWitt equation attempts to describe the quantum state of the universe as a whole.
( if that is what you mean )

It has a problem with time, though.
