The many, many dimensions of String Theories and the Multiverse constitute the extremes of fairytale physics brought about by the continuous cobbling-together of more and more fantastical, fictional forces, effects and invented particles in attempts to make sense of the puzzles inherent in the empirical evidence of experiments such as Young's double-slit phenomenon.

But even the photon, the point-particle of light, does not bear close examination. A while ago, I was having a discussion with an Open University student when I called the photon a massless particle. He looked at me with disdainful suspicion and asked how can a particle that carries energy, be massless?

It takes the undoctrinated to ask such glaringly obvious questions, when practicing physicists accept this kind of nonsensical description without question. Quantum physicists are too fond of suggesting that the quantum world with its "purely quantum effects" just cannot be related to the macro world in which we live.

The definition of the photon makes no sense - not to common sense. But it should!

This Blog offers a simple, common-sense description of the photon, and of every particle: from this, and directly from this, applying the same logical explanation, I am able to desribe all quantum effects and processes in four-dimensional spacetime, with no extra dimensions, no alternative universes - and far, far fewer particles.

Quantum Entanglement

Quantum entanglement is a quantum mechanical phenomenon in which the quantum states of two or more objects have to be described with reference to each other, even though the individual objects may be spatially separated. This leads to correlations between observable physical properties of the systems.
For example, it is possible to prepare two particles in a single quantum state such that when one is observed to be spin-up, the other one will always be observed to be spin-down and vice versa, this despite the fact that it is impossible to predict, according to quantum mechanics, which set of measurements will be observed.
As a result, measurements performed on one system seem to be instantaneously influencing other systems entangled with it.
But quantum entanglement does not enable the transmission of classical information faster than the speed of light.
Quantum entanglement has applications in the emerging technologies of quantum computing and quantum cryptography, and has been used to realize quantum teleportation experimentally.
At the same time, it prompts some of the more philosophically oriented discussions concerning quantum theory.
The correlations predicted by quantum mechanics, and observed in experiment, reject the principle of local realism, which is that information about the state of a system should only be mediated by interactions in its immediate surroundings.
Different views of what is actually occurring in the process of quantum entanglement can be related to different interpretations of quantum mechanics.

Quantum Entanglement - a Report by John Brindley

Summary (from the above Report):

From the first tests of two-particle entanglement to the very latest, results have shown violations of Bell’s inequality in all its forms and in every variation of experimental set-up. The contextuality problem has been addressed and tested with single neutrons, also showing results that violate Bell’s inequalities. As no test has been able to prove the existence of any local hidden variables, the results now show the quantum-mechanical interpretation of natural reality is accurate in its predictions and conclusive in results.

Research and development into technological systems and devices using entanglement effects is already well established; the current and continuing success of which must surely end the controversy between local-realist and quantum-mechanical theories.

But while the quantum-mechanical interpretation of reality is strongly established, quantum mechanics still lacks a description of the mechanism by which separated systems remain entangled over potentially any distance. Such a description would necessarily define and perhaps resolve one of the deepest mysteries at the heart of our understanding of physical reality.

The following video contains such a description, showing how the theory of Unified Absolute Relativity solves this, deepest of quantum-mechanical mysteries:
