Dear Vesselin Petkov,
I agree! A couple years ago I posted an addendum to Moving Dimensions Theory here at fqxi which stated, "Gravity is not quantized as there is nothing to quantize."

3. Why Electromagnetism is Quantized (Digital) in Nature, while Gravity is Continuous (Analog)
Fig. 2 and the Fig.1 at the end of my earlier paper xix bring to light several remarkable features of MDT. MDT explains why energy is quantized and why clocks run slower in stronger gravitational fields where space is stretched. Time, as measured on a light clock, is also stretched, but only because of a
foundational invariant which never stretches--the expansion of x4 relative to the three spatial dimensions--a foundational invariant which maintains the invariance of both c and ħ, while curving the measurement of time in proportion to the curvature of space. Even though time and space are stretched, the expansion of x4 remains invariant: dx4/dt=ic. Space is continuous (analog), while quantization (the discrete, digital character of energy and measurement) arises from the quantized invariant expansion of x4 relative to the three spatial dimensions in units of lp. The invariant wavelength of the expanding x4―chops‖ measurements of space--of time, energy, and momentum--into discrete geometrical units proportional to the Planck action ħ and lp, while also providing the fundamental wave nature that gives rise to Heisenberg's Uncertainty Principle and Huygens' Principle (seen in Fig. 2) across all realms, as well as the fundamental space-time geometry which parcels action and energy in discrete units proportional to ħ, exalting the quantum. It is enough for x4 to be wavelike in nature, while the three spatial dimensions are continuous, to give rise to the quantum, digital features of QM, and the classical, continuous nature of gravity. In the electromagnetic field, force hinges upon the transfer of physical particulates--photons, while in the gravitational force, no particles are transferred, as gravity arises via
the geometrical curvature of space-time, as my mentors Wheeler
xx and Taylor taught.
Freeman Dyson writesxxi, ―(Brian) Greene takes it for granted, and here the great majority of physicists agree with him, that the division of physics into separate theories for large and small objects is unacceptable. General relativity is based on the idea that space-time is a flexible structure pulled and pushed by material objects. QM is based on the idea that space-time is a rigid framework within which observations are made. Greene believes there is an urgent need to find a theory of quantum gravity that works for large and small objects alike. . . As a conservative, I do not agree that a division of physics into separate theories for large and small is unacceptable. . . I propose as an hypothesis that it is impossible in principle to observe the existence of individual gravitons.‖ MDT sides with Dyson and Occam's Razor, as well as Einstein and Planck. Let us first see a graviton, or find a consistent, unique theory that predicts gravitons, before we conclude that gravity must be quantized.

WHY GRAVITY IS NOT QUANTIZED, WHILE E&M IS, PART II
Gravity is not quantized as there is nothing to quantize. In the above thought
experiments, a photon traveling away the massive star experienced a gravitational redshift--it lost energy. In losing energy, no energy was emitted in the form of photons nor mass nor matter nor any other form. The photon lost energy because it surfs the expanding fourth dimension, preserving its original length in the fourth dimension where it was emitted, while entering space that is not quite as stretched--hence its wavelength becomes longer. But this loss of energy was accompanied by no physical emission of photons nor matter, nor any entity that can be quantized. Hence gravity does not rely on the emission and propagation of physical entities to transmit forces, nor alter energies, and it cannot be quantized, as both empirical evidence and hundreds of millions of funding have demonstrated over the past thirty-odd years. Likewise, a photon heading towards a star is blue-shifted. No physical matter nor photons are added, but rather, the underlying curvature of space, which is continuous, results in the photon gaining energy. So it is that in altering the energy of objects, gravity neither adds nor extracts physical entities--neither matter nor photons nor gravitons. Contrast gravity to E&M. In order to accelerate an electron via an electromagnetic wave, we must add photons to it via the electromagnetic wave. Physical entities--photons--must be added to a charge in order to accelerate it; and too, a decelerating electron emits photons as it slows down. And these are of course quantized because the fourth expanding dimension, which carries photons, is quantized in its expansion.
So it is that forces in electricity and magnetism require the exchange of physical entities, whereas gravitational forces arise entirely because of the quantized, invariant expansion of the fourth dimension superimposed over the curvature of continuous space, which is continuous. Photons are but matter surfing the fourth expanding dimension, and thus, like the quantized fourth expanding dimension, they are quantized proportional to the Planck length. The fourth dimension continually takes a local point and distributes it
nonlocally; and so it is that physical entities such as photons and electrons have nonlocal properties (wavelike), as well as local properties (particulate).
But the gravitational field does not need particles to transmit energy to photons nor any other entity, as we have seen. Gravitational forces rely entirely on the curvature of space relative to the quantized invariance of the fourth expanding dimension.
Because gravity does not need particulate nor physical entities to transmit energy, there is nothing to quantize. So it is that MDT explains both gravitational forces and QED; while showing that they both derive from a deeper physical reality--a hitherto unsung *physical* invariant--the expansion of the fourth dimension relative to the three spatial dimensions--that unifies
phenomena in quantum mechanics, relativity, and statistical mechanics, while accounting for time and all its arrows and asymmetries across all realms. And too, Huygens' principle and Heisenberg's Uncertainty principle are accounted for across all realms.
MDT offers a most powerful, simple unifying theory. Expect the Inquisition!
