Everyone hates the gross simplifications they cause unnecessary confusion

I mean, correct me if I'm wrong, but I always interpreted it as:
Existence in a state is something that must be measured to determine. Therefore nothing exists in any state prior to measurement, just the probability to.
It's akin to a sort of non-homogeneous reverse entropy, where certain degenerate states are statistically favored when partitioning the available energy (EDIT: that can converted to matter)
Just like how enthalpic events cause for a need to probe space for states to spread its energy into (entropy), so too does the event of a measurement in QM probe space for favored states to partition matter into.

Theoretical physicists sometimes say these days that space is emergent from entanglement, that entanglement doesn't happen in space, but space emerges from entanglement.
I think a corollary of that is that the interaction /entanglement involved in measurement doesn't happen in space, but space emerges from the entanglement of a measurement operation.
In that kind of context, the best way I could describe "where" it is before measurement plays off a phrase I heard from Thomas Van Reit. He says in string theory, we really shouldn't say there are 10 dimensions, as if the extra dimensions make up actual space. We should say there are 3 spatial dimensions, one time dimension, and a lot of junk that gives the particle 6 extra effective degrees of freedom. (Edit: This video at exactly 59 min. watch?v=9m0pbZH9lWs .)
I think where the particle is before measurement is somewhere in the junk.

Just like light, basic particles are waves contained by neighboring particles into stable selectively stationary particles same way as for example light photons can orbit the black hole.
|
In fact, it would make no sense for the same observer to "see" a copy of the same particle. It is for this reason that particles are not defined or determined until they are measured. The only thing that exists is its potential, its probability. But although this probability is not a real object, it is still possible for it to interact with the observer's reality without actually emerging but interfering with itself.

If we need "made of" then the basic element of reality is the events. This solves the problem of defining existence of particles while not interacting.
|
For any thing that is in motion, its exact location can never be known until it is observed or measured in some way.
|
Someone should tell physicists that telling a lay person that something is magic, is not intuitive. And it not helpful in any circumstance.
|
Sometimes i think i grasped this then i realise i had misunderstood and im back to square one

"I don't know"
Three hard words for a scientist.
|
Couldn't you say that superposition is just a type of vibratory motion so that a particle is constantly moving into different positions?
|
I believe that the fundamental laws of our universe must allow for consciousness and free will to exist based upon my observation of the existence of these attributes. My guess is that the mysteries at the heart of quantum mechanics arise from this requirement.
|
For hundreds of years we've known about the conservation of energy and therefore known that particles are not in two places at once. The only contradiction would be if the energy is spread out, i.e.a wave.
|
You say that the particle is NOT in 2 states at once, but I don't think that conclusion is warranted either. Wave function collapse only says what happens during a measurement, not what happens before. Given how unintuitive QM can be, should we stay open to non intuitive possibilities?

Por favor pongan Subtítulos en Español Latino, Gracias

This is very similar to when Newton wrote the formula for gravity. It worked and explained it close to perfectly. But he didnt know why it worked. It was Einstein who figured out the why gravity worked and its opened up whole new worlds of physics for us to explore.
Imagine what we will discover when we solve this problem and figure out why it works this way.

It it a particle or a wave? Is it a pixel or binary loop? Both represent a volume energetically no? Digital code, Genetic code. Particles emit radiation, so do pixels. Proteins and algorithms serve similar functions, digital vs biological.

Bro just denied superposition
|
Wave particle duality, particle wave duality. Without the stone being thrown into the pond there wouldn't be ripples in the pond. But without waves of quantum fields there may not be any stones.

What do quantum particles do when no one is looking? https://www.youtube.com/watch?v=Zm1xhph9iHY
