MULTIVERSE IDIOCY DISSECTED

Physicist Sean Carroll, “explaining why the many-worlds approach is not completely insane“, says: “If the particle can be in a superposition of two states, then so can the apparatus.”

This fundamental error, that everything is a superposition of states, is the essence of the idiocy of the Many World and Multiverse error.

Why Mr. Physicist Carroll? Why is it that, for you, if something is a superposition of two possibilities, then so can be something else? Where is the logic in that? There is none whatsoever. Let me show you why. Why that’s illogical.

Maybe, sometimes, because something can be cut in two, say a fish, another fish can be cut in two, or a million fishes can be cut in two, indeed.

The fact that fishes can be cut in two, because one fish can be cut in two, does not imply that everything else can be cut in two.

For example, the fact that one can cut fishes in two does not imply that the sea can be cut in two. Such is the Multiverse error, a very fishy argument.

That some process can result ultimately in two states, does not mean that the sea, or anything else, will be a “superposition of two states”.

When we mention “the particle” (whatever that is) and the apparatus (whatever that is) we are talking here about things of completely different natures, obviously.

What’s the difference? Or differences?

Obviously, “the particle” is being measured. And it’s measured by “the apparatus”.

One is “Quantum”, “the particle”. The other is classical, the “apparatus”.

What’s the most basic difference between “Quantum” and “Classical”? “Quantum” is dominated by DISCRETE states. “DISCRETE” here is in the strict mathematical sense (in bijection with a subset of the natural numbers, N).

Discreteness of light emission is how Planck explained the Blackbody Radiation and resolved the Ultra Violet Catastrophe.(1900 CE)

Discreteness of light reception is how Einstein explained the Photoelectric effect. (1905 CE.)

Discreteness of electronic orbitals is Bohr explained the structure of atoms. (1912 CE.)

Discreteness of non-self-interfering-to-destruction waves is how De Broglie explained all the subjacent discreteness, uncertainty, interference and basic dynamics. (1923.)

Classical mechanics is NOT discrete. We do not understand why. It’s a major mystery.

But the passage from Quantum to Classical has been studied experimentally in simple, particular (namely made of PARTICLES) systems.

Let’s go back to Sean’s statement:

“If the particle can be in a superposition of two states, then so can the apparatus.”

I just said that “Quantum” is characterized, as its name indicates, by discreteness, a superposition of states.

In other words, in Sean’s view the foundation of the Many World Interpretation/Multiverse theory is that Quantum = Classical.

Yet, the very concept of “Science” comes from the ability of scindere, to cut in two, to make distinctions.

By ignoring the most basic distinction, that between Quantum and Classical, the Many Worlds/Multiverse theory reveals itself to not be science.

Yet, it’s even worse than that. The Multiverse error is reminiscent of the blind alley of the Epicycle theory of Ptolemy and company, 2,000 years ago.

Notes: 1) The error was inaugurated by Everret, a student of Wheeler, 1963 CE. At the time it was viewed as horrendous (probably for the reasons above, but they were left unsaid; the preceding is my reasoning, entirely). Everret was driven out of research physics (although there were lots of jobs at the time).

2) Bohr and his followers had got the ball rolling, by murky attacks against reality itself. It was debatable at the time, as some then-not-discovered particles (say neutrinos) led to apparent violation of energy-momentum conservation.

3) The philosopher Heidegger, maybe inspired by some of the less wise, contemporaneous statements of Bohr and company, insisted that the distinction between “subject” and “object” be eradicated. Unsurprisingly, he soon became a major figure of Nazism, where he was able to apply himself to further lack of distinction.

  1. Ian Miller Says:

    I would argue that both classical and quantum mechanics are discrete because action is discrete. Thus you cannot find anything between nh and (n+1)h. At the quantum level, where n is, as often as not, equal to 1 the gap between the possibilities is clear, but when n equals something like 10^24, the gap is, well, insignificant and undetectable. There wis no mystery as to why classical mechanics is continuous; it is not, but the gaps are undetectable.

    • Patrice Ayme Says:

      Dear Ian: What you exposed is the conventional view. This is the one Sean Carroll embraces.

      However, the first problem with it, is that it’s not proven. It’s not proven that all there is are states.

      That implicit axiom has a magnificent pedigree: Einstein got the ball rolling. Einstein assumed that the “Licht Quantum” (named photon by others in 1927) was a dynamical process. However, all he needed for the photoelectric effect was for the photon to end up in discrete states with energy E = hf.

      Einstein supposed more than what he needed, and so his children did too. Later Einstein was unhappy because his children misbehaved. But he should have educated them differently.

      Why don’t I believe in this: All There Is Is States mantra? Simple: a fundamental processes is as Quantum Mechanics describes it: a time-parametered wavefunction ensemble in a Hilbert space spanned by said states. Fine. That fundamental process, THUS, is NOT a state.

      This is a case of simple logic: if W is not S, then W is not S.

      The formalism ITSELF says that the world is made of states AND fundamental processes. My friend Feynman was crafty enough to recognize the problem, and, at least in the title of one of his books, make the distinction.

      Thus what’s a classical object? It’s an object made of Wavefunctions AND States.

      What’s a Quantum object? Something that will end up in a State.

      At least, that’s what I propose.
      Experiments have recently been conducted to study the transition.

    Bohr was on both sides of the general argument. Quantum was not everything, he said. But he toyed with getting rid of reality.

  3. Paul Handover Says:

    I would have ‘Liked’ the post if I understood it!

  4. gmax Says:

    Could you push your argument further? I think you can. You said something more precise about this, once, long ago. It struck me as very deep, and had to do with Schrodinger cats

    • gmax Says:

      Actually rereading your answer to Ian Miller, I think it is there: classical objects have waves, not just states

      • Patrice Ayme Says:

        Exactly. I was thinking the same. Have to expand that argument a bit, mostly rephrase it in one package. But time is real short, and I am travelling big time.
