THE OBSERVER AND OBSERVED IN EINSTEINIAN FRAMES OF REFERENCE
According to Special Relativity, experiments are overrated by modern science since the truths revealed by experimentation are necessarily restricted to one frame of reference. Regarding the question of length contraction in Special Relativity - Einstein wrote in 1911 that "It doesn't 'really' exist, in so far as it doesn't exist for a co-moving observer; though it 'really' exists, i.e. in such a way that it could be demonstrated in principle by physical means by a non-comoving observer." (Einstein [1911]. "Zum Ehrenfestschen Paradoxon. Eine Bemerkung zu V. Variĉaks Aufsatz". Physikalische Zeitschrift 12: 509–510) Demonstration "in principle by physical means by a non-comoving observer" is the same meaning as "demonstration by experiments performed by scientists not moving at the speed of light".
Now relate the previous paragraph to this quote - “While an observer stationary with respect to an electric charge will see it as a source of electric field only, a second observer moving relative to the first will see the same charge as a source of both electric and magnetic fields in a way dictated by special relativity.” (Penguin Encyclopedia 2006 - edited by David Crystal - 3rd edition, 2006 - ‘electromagnetism’, p. 443)
So, if a co-moving frame of reference is adopted, we’d need to revise Maxwell’s propagation of electromagnetism by oscillating electric and magnetic fields. In addition to electric-magnetic duality not existing, the unification of all things in space and time (perhaps via quantum gravity) means wave-particle duality would not exist in all frames of reference. It would only exist for a non-comoving observer: it could be demonstrated “… by experiments performed by scientists not moving at the speed of light". * According to this comment, saying light travels is merely convenience, like saying the sun rises and sets when we know Earth is rotating. If we shift our understanding of the universe from one based on experiment to one in which observers and objective reality are united/entangled (one in which we’re in harmony with the universe and therefore co-moving with it), electric-magnetic duality would no longer be perceived. It would then be better to say,
“particles (photons) of light and microwaves etc., that ‘travel’ through space-time would have relatively little movement themselves. It’s the disturbances from the sources of electromagnetism (ripples in space-time called gravitational waves) that travel. A gravitational wave can't travel light years but only the quantum-scale distances between photons and gravitons. These particles then re-transmit the vibrations or disturbances they received, similar to the way an electric impulse travels from one nerve cell to the next. Neurons' electric impulses use chemicals called neurotransmitters - spacetime's gravitational and electromagnetic waves use BITS (the binary digits of 1 and 0) which act as transistors to boost the waves' strength and prevent power loss as the light years are crossed. This agrees with John A. Wheeler's geon - an electromagnetic or gravitational wave which is held together in a confined region by the gravitational attraction of its own field energy. Maxwell's electric and magnetic oscillations would, at least in a comoving frame, "be heId together in a confined (subatomic) region" (since light years can be crossed in the direction of propagation, waves can also exist in macroscopic regions in other directions). If there is little movement of photons and gravitons, the universe could not be expanding (or contracting) but its space and time is static. The Big Bang has impressive points … leading to the idea that it’s a necessary stepping-stone. For example, the Big Bang’s supposed origin from quantum fluctuations is reminiscent of bits switching between 1 and 0.”
Einstein wrote “Do gravitational fields play an essential role in the structure of elementary particles?” (A. Einstein [1919]: “Spielen Gravitationfelder im Aufbau der Elementarteilchen eine Wesentliche Rolle?” [Do gravitational fields play an essential role in the structure of elementary particles?] Sitzungsberichte der Preussischen Akademie der Wissenschaften, [Math. Phys.], 349-356, Berlin) This paper, asking if subatomic particles result from gravitational-electromagnetic (G-EM) interaction, is often dismissed because the discovery of the weak and strong nuclear forces is said to make it out of date. But an Opinions-article (R. Bartlett. “The 5th Dimension and its Implications for the String Theory, Conservation of Energy and Heisenberg Uncertainty Principle” – published October 2023 in the journal “IPI Letters” https://doi.org/10.59973/ipil.29) shows, in sections 3 and 4 (Vector-Tensor-Scalar Geometry), that G-EM interaction can produce the mass and quantum spin of not only the nuclear forces’ bosons but also of the Higgs boson. If looked at from the frame of reference of an observer co-moving with the universe, the weirdness of wave-particle duality vanishes and quantum mechanics becomes as understandable as the macroscopic world (gravitational and electromagnetic waves interact to produce a momentum and pressure which can be interpreted as a particle. The particle never actually exists in more than one place - it only appears that way in the human frame of reference).
