Probability in MWI

Which has nothing to do with the topic. Focus, please.

The problem with the Many World Interpretation is the same problem physicists have with ghosts.  There is no physical evidence to support the claim.  It's like wandering through your house, from the living room to the kitchen, and trying to make the argument that because you changed rooms, you changed houses.  Or because an onlooker looks at your house and doesn't know where you are in your house, that you must be in the multi-house verse.

Of course there isn’t. It’s an interpretation.

I don't wish to deprive you of your fascination with MWI.  My goal is to offer an interpretation that leads to experiments that lead to manipulating the position/momentum quantum states of gravitons, which results in gravity field effects.

The physics community always proclaims that QM is weird!  Which means that you don't understand what's happening. 

No. They are simply saying it is weird. Don't confuse "weird" with "don't understand". They are not the same thing.

I'm not so sure that's true.  There are some people who believe that QM is so weird, that there exists an infinite number of universe every time someone decides what they're going to have for dinner.  I mean, if you have to ask for an infinite number of universes to make your interpretation sound reasonable, but there are no supporting facts or evidence, then where are  you?

You don't know the meaning of 'interpretation', do you ?

You might want to save that for many of the other universes, where Swantsont expressed some fascination.

MWI is nonsense.

Fortunately in this Universe you are welcome to feel that way, and are under no obligation to like it or use it.

My choice also, at least in this one.

Can you prove that?

Have you ever tried to write down a quantum field theory for self-interacting spin-2 gravitons, with the appropriate classical limits? It’s a doable exercise. Unfortunately the end result is a QFT that is non-renormalisable, so it does not yield any physically meaningful predictions.

Clearly, this approach leads exactly nowhere.

You don’t need to use it, you can just stick to the Copenhagen interpretation, or use any of the numerous other interpretations. Remember, you are always dealing with the same model, these aren’t distinct theories.

In a Wave functions = expanding gravitons interpretation, the gravitons are supposed to begin at a point, expand spherically at the speed of light, and eventually overlap.  Two expanding gravitons would overlap in such a way as to combine their quantum states for momentum and position.  When you have 10^100 gravitons that are several light seconds or larger diameters, then you really just get the spacetime continuum and the Einstein equations.  Renormalization might be a requirement for a quantum field theory calculation, but it's not a priority for nature to create gravity fields. 

I'm pretty sure we would have to conduct new experiments on quantum entanglement fields before we could get data that could be described with mathematics.  But it's more important to figure out if a quantum entanglement field can serve as a gravitational potential energy field.  If we can demonstrate that, then we can work towards tractor beams and chemical free propulsion.

Incidentally, if wave functions = expanding gravitons, then wave functions DO NOT COLLAPSE.  They expand, at the speed of light, beyond the quantum system; essentially they escape quantum systems by expanding, not collapsing.

I’m definitely a skeptic about MWI, but there’s no real proof against it. 
 

The ghost analogy for MWI is a pretty accurate analogy, but all that means is there’s no proof MWI is real. Not that there’s proof against it.

That’s because it’s an interpretation, not a theory.

It’s akin to saying there’s no proof against a mnemonic, like “Every Good Boy Deserves Favor” or ROY G BIV

The Moody Blues interpretation and the British Navy interpretation are equally valid.

So they deserve both flogging and favour and food ?

They must be very deserving indeed.
