Summary: Does Richard Feynman's multiple histories ignore alternative histories?
Did Richard Feynman's multiple histories (https://en.wikipedia.org/wiki/Multiple_histories) ignore the existence of other alternarive histories or paths?
I ask this referring to this comment from this page...
Summary: Could MWI (Many Worlds Interpretation) create universes with fundamentally different physical laws?
Physicist John Wheeler proposed along with Hugh Everett and Bryce DeWitt the 'Many Worlds' Interpretation of Quantum Mechanics (although he expressed some doubts about its validity)
I...
Can anyone elaborate on Deutsch's attempt to solve the incoherence problem?
He postulates a continuously infinite set of universes, together with a preferred measure on that set. And so when a measurement occurs, the proportion of universes in the original branch that end up on a given branch...
Hi,
Is anybody able to explain how energy is "distributed" in the many-worlds interpretation. I'm using scare quotes as I think this may be the wrong line of thought. It's tempting to imagine energy being distributed amongst subsequent branches as the wave function evolves but I'm not certain...

Every derivation from the MWI of the born rule is circular. http://fmoldove.blogspot.com/search?q=MWI
So my question is, can the MWI state the born rule as a postulate (without deriving) and still be a coherent interpretation of probability?
The most famous argument against this notion is by...
All the literature on the quantum eraser that I've seen is grounded in the Copenhagen interpretation of quantum mechanics. It's very easy to understand the experiment in those terms.
Do you know how quantum eraser experiments are interpreted by the de Broglie–Bohm theory? What is erased in this...
Hello all, I have only seen this paper brought up here once before based on the search function 2 years ago, and the thread devolved into something off topic within the first page.
I am asking in reference to this paper:
https://arxiv.org/pdf/1604.07422.pdf
Which claims to show that single...
If I understand the many worlds QM interpretation correctly, for every quantum event the universe divides.
However not all quantum events have a 50/50 probability. How does the many worlds interpretation deal with quantum events that have,say a 1/3 2/3 probability split?
Just a reminder to you all, I am just a layman...
These experiments were both done is what is called a penning trap.
I think this only proves the version of MWI where the universe doesn't actually split. The "bare" theory, where no new matter is created.
According to MWI an electrons...
If the MWI would be true, wouldn't there be at least one reality where human civilization advanced much faster than we did and therefore: contacted all other universes; destroyed all the universes; colonized all other universes; etc.
Since, as far as we know, this has not happened, doesn't this...
I have a question regarding the ontology of the many-worlds interpretation which by my assumption shows some deficiencies in this way of thinking.
When many worlders describe branching and effects giving rise to multiple worlds they typically invoke Schrodinger cat-type experiments where from a...
How does MWI deal with the destruction of interference in the double slit experiment when a detector is placed at the slits? Since the wave function never collapses, and the universe doesn't actually split in MWI, how does the interference go away? Does the measuring device at the slits reshape...
On wikipedia it says that MWI doesn't explain quantum tunneling well.
"A tunnelling particle would have more energy than what is actually measured in experiments."
What do you guys think?
On wikipedia, I found one of the objections to MWI.
"We cannot be sure that the universe is a quantum multiverse until we have a theory of everything and, in particular, a successful theory of quantum gravity.[73] If the final theory of everything is non-linear with respect to wavefunctions then...
Does anyone know of a written refutation of the quantum physics David Deutsch presents in his book _The Beginning of Infinity_?
PS I have no intention of summarizing the material. If you aren't familiar with it, I don't want you to try to argue with a summary.
Hi there! Alright, so let me start off by saying I'm a biochemist by trade, but have an extreme (and possibly unhealthy) interest in the more bizarre aspects of modern physics. Admittedly, I don't understand the mathematical formalisms associated with the theories I know of, so bear with me if...
Hello, sorry if I created new thread that is already open, but I did not find answer. I would like to ask you about measurement problem (double slit experiment) and many worlds. When interference pattern is created, the dot on screen just show us in which branch or world we are. But if we...
