What is the Origin of Intrinsic Quantum Spin?

Spin quantum number is the fourth parameter needed to uniquely describe the quantum state of a, say, fermion such as an electron. It was originally postulated by the brilliant, albeit caustic, Austrian physicist Wolfgang Pauli. Shortly afterwards some physicists interpreted it as self-rotation. Pauli himself was not happy with this interpretation because a quick calculation shows that such a mechanical supposition requires a superluminal rotation of the electron's "surface," which goes counter to the dictates of the special theory of relativity.

So how is quantum spin explained then? Is there a physical model for it?

The standard answer to these questions is that we are supposed to think of quantum spin as a two-valued intrinsic quantum degree of freedom, corresponding to an "intrinsic" angular momentum, with no classical analog. And the majority of physicists follow this catechism.

But I don't!

When self-rotation so neatly explains the two-valuedness (clockwise-counterclockwise), and the angular momentum aspect of this phenomenon that I do question the validity of Pauli's (and others') concern about the faster-than-light rotation. The special theory of relativity puts a speed limit only on the propagation of causal information. I don't think electron's spinning faster-than-light can be harnessed to breach that limit.  After all, we are familiar with many superluminal but non-causal events: Isn't it true, for example, that quantum entanglement can travel faster than light? Or that there are galaxies in our universe that are receding from us superluminally? Or that the early universe expanded exponentially with faster-than-light speeds, according to the cosmic inflation theory?

Having presented my perspective on quantum spin,  I would like to now go one step further and ask what the primal origin, the cause or the source of this, fundamentally two-valued, spin is, which, one has to note, is possessed universally by all elementary particles.

Again, why is it that it will be either parallel or antiparallel to a given measurement axis? How is possible that all the fundamental particles have the same property, which never dissipates?

My answer to these questions is to do with my cosmological model that unifies and explains, in one stroke, both the dark energy and dark matter, namely the Big Spin. As those of you who have read my two papers (see on the topic, and a blog post here, will recall that I have proposed a globally rotating space-time model, that I call the Big Spin, which is a natural cause of the early cosmic inflation, and the relatively recent accelerated expansion of the universe and the galaxy rotation curve anomalies.

I hereby do posit that, in addition to being a strong and natural candidate to explain our outstanding dark energy and dark matter dual problems, a Big-Spin model does also naturally explain the origin of "intrinsic" angular momentum of elementary particles. That is because these particles at the initial singularity started to spin with a gargantuan primordial angular momentum of the Big Spin, not Big Bang!, with superluminal rotation speeds. As the universe expanded, the spin orientations  got thermalized and hence the current two-valued, clockwise-counterclockwise characteristics.

  2. It adds to a brilliant (but reasonable) idea for a unification picture, that will soon replace the Big Bang theory and model ...

    All spontaneous rotations and "Dark phenomena" are now explained and unified via Universal Inertia and Rotating ideas, which will make Serkan Zorba the new Galileo ...

    Unification seems to be the logical and natural way the Universe is structured and operates.
