In this post, I’ll take a quick look at superfluid vacuum theory, an idea from the physics and cosmology discard pile, that may be related or aligned with **NPQG**

Superfluid vacuum theory (SVT) is also known as BEC vacuum theory, where BEC stands for Bose-Einstein condensate, which is a state of matter that is a superfluid gas. SVT theory models spacetime as a superfluid gas.

Superfluid vacuum theory (SVT), sometimes known as the BEC vacuum theory, is an approach in theoretical physics and quantum mechanics where the fundamental physical vacuum is viewed as superfluid or as a Bose–Einstein condensate (BEC).Wikipedia

The microscopic structure of this physical vacuum is currently unknown and is a subject of intensive studies in SVT. An ultimate goal of this approach is to develop scientific models that unify quantum mechanics (describing three of the four known fundamental interactions) with gravity, making SVT a candidate for the theory of quantum gravity and describing all known interactions in the Universe, at both microscopic and astronomic scales, as different manifestations of the same entity, superfluid vacuum.

The core idea, published by Sinha/Sivaram/Sudarshan in 1975, is that the particles of spacetime are a variety of fermion anti-fermion pairs describable by macroscopic wave equations. Because the scale of the spacetime particles is so small, there is no direct observational evidence to support or falsify this theory.

SVT differs from two major tenets of GR-QM era theory. SVT has an aether, which was incorrectly ruled out by the Michelson-Morley experiment. However, a superfluid was not in fact ruled out by Michelson-Morley. Furthermore the modern roiling quantum vacuum is quite different from Einstein’s abstract continuous curvy spacetime geometry.

SVT does not break with the Inflation / Big Bang theory, nor the cosmological constant, aka dark energy. That is a very large difference with NPQG, although I don’t see how these ancillary topics should be related to SVT in the first place.

The concept of a luminiferous aether as a medium sustaining electromagnetic waves was discarded after the advent of the special theory of relativity, as the presence of the concept alongside special relativity leads to several contradictions; in particular, aether having a definite velocity at each space-time point will exhibit a preferred direction. This conflicts with the relativistic requirement that all directions within a light cone are equivalent.However, as early as in 1951 P.A.M. Dirac published two papers where he pointed out that we should take into account quantum fluctuations in the flow of the aether. His arguments involve the application of the uncertainty principle to the velocity of aether at any space-time point, implying that the velocity will not be a well-defined quantity. In fact, it will be distributed over various possible values. At best, one could represent the aether by a wave function representing the perfect vacuum state for which all aether velocities are equally probable.

Circa 2005 B. L. Hu visited the topic of spacetime as a condensate. Dr. Hu observed that several microscopic theories of spacetime and matter, when considered at the low energy, long wavelength portion of the scale will produce the mathematics of general relativity. **Hu suggests it is more important to understand the structure of spacetime than to quantize gravity.** Hu says that Sakharov viewed spacetime as a “collective state of matter in a limiting regime of interactions.” Hu suggests that spacetime is a condensate in the entire sub-Planckian temperature regime. Hu gives up on general relativity beyond the Planck scale which is where he thinks the deeper structure of spacetime and matter reveals itself.

In the relativisticquantum field theorythe physical vacuum is also assumed to be some sort of non-trivial medium to which one can associate certain energy. This is because the concept of absolutely empty space (or “mathematical vacuum”) contradicts the postulates of quantum mechanics. According to QFT, even in absence of real particles the background is always filled by pairs of creating and annihilating virtual particles. However, a direct attempt to describe such medium leads to the so-calledultraviolet divergences. In some QFT models, such as quantum electrodynamics, these problems can be “solved” using therenormalizationtechnique, namely, replacing the diverging physical values by their experimentally measured values. In other theories, such as the quantum general relativity, this trick does not work, and reliable perturbation theory cannot be constructed.

Perturbation theory uses small deviations to explore a mathematical function near a singularity. These perturbations do not work for QFT in regards to the quantum vacuum. Rather than determine the reason why this is the case, QFT physicists invented a new technique called “renormalization” to overcome the issue. This is a fundamentally flawed technique because the real issue is that the spacetime æther is actually discrete and the singularity and non-perturbative nature are signaling this discrete physical implementation to the scientists but they have not realized what is happening at the finest scales of nature.

NPQG teaches of a spacetime æther which is implemented by immutable point charges in dipole constructs. It may have the characteristics of a BEC vacuum superfluid gas of particles. NPQG goes farther in describing the structure of those particles in terms of fundamental electrinos and positrinos that also compose standard matter. The open question is exactly what composes the spacetime æther. All of the following are candidates in NPQG:

- tau dipoles, the simplest structure, a single electrino and a single positrino chasing each other’s shadow in an orbit.
- photons and/or neutrinos that have redshifted over enormous travel distances to the point where their Noether cores lose their planar shape and they drop to near zero velocity.
- reaction products of these tired photons and/or tired neutrinos
- a distributed structure of unbound point charges
- a composite of pro and anti Noether cores arranged in a Helium like configuration of two pro and two anti Noether cores.
- some combination of the above and any other low apparent energy detritus.

My conclusion is that superfluid vacuum theory is yet another idea from the discard pile of physics that actually has merit and should be considered a precursor to NPQG.
