The true mystery of the universe is a moment of time, not the universe itself - Khalid Masood
One has only to recognize the striking resemblance of the Prandtl-Glauret transformation (PGT), and its Prandtl-Glauret singularity (PGS), with that of the Lorentz transformation, to suspect that the two transformations are complementary analogs with shared properties suggesting a description of space to be an ideal compressible fluid, with a limiting speed, v/c.
The Theory of General Relativity (TGR) models spacetime as a geometrical surface whose curvature is a consequence of proximity to mass/energy The theory of Gravity and Fluid Spacetime poses space to be an ideal compressible fluid of minimal density, at or above that of vacuum energy and/or false vacuum energy. The fluid theory of gravity (FTG) identifies gravity as the radial flow of an ideal (inviscid) compressible space. Consequently, Newtonian forces play no part in this fluid description of gravity.
The resulting relationship between mass and spacetime, based upon this theoretical premise, presents not only a plausible explanation for the effects of gravity and spacetime, it mirrors in many ways the relativistic properties that are observed relating the metrics of length and clockspeed to the relative density - gravity - of local space; that is to say, FTG is a "local" theory.
The theoretical paradigm offered by the concept of Gravity and Fluid Spacetime is a simple one to visualize, albeit unconventional and computationally complex at the extremes of scale. It embraces the essence of Einstein's two theories of Relativity; however, it does not model spacetime in the more traditional geometric fashion, relating local curvature to the regional mass/energy content. Nevertheless, the fluid theory of gravity (FTG) does relate gravity to the radial flow of space, where the spatial density is identified with the local energy state - which presents itself as a pseudo pressure - a type of "false vacuum" quantum field.
That local spatial density can effect the temporal clock rates of distant galaxies suggests that it may be at the crux of speculations regarding the posed existence of dark matter and dark energy, when the variance of relative clock rates is not taken into consideration.
MAN, KNOW THYSELF
 The admonition, "Know thyself", attributed to Socrates and at least a dozen other philosophers can find no better occasion for reflection than within these sixteen chapters on Gravity and Fluid Spacetime. Socrates put it plainly, that people make themselves ridiculous when they try to know obscure things before they know themselves.
Epicurus, circa 300 BC, is a key figure in the development of science and scientific methodology because of his insistence that nothing should be believed, except that which was tested through direct observation and logical deduction. Epicurus was one of the first atomists who posed the existence of atoms, believing that the fundamental constituents of the world were indivisible little bits of matter - atoms. While Epicurus could not "observe" atoms, by "logical deduction" he reasoned that their existence could be deduced "indirectly" by aspects of observation.
To "know thyself" we must be aware that all observation is derived via human perception; and, that perception - both by senses and reasoning - is subject to conditions of personal relativity. We may correctly reason that our observations are subject to our state of being - our age, our health, our intellectual capacity; and, most importantly, our perception of self .
In the following discussion, the reader will be challenged in his perception of the world as he perceives it - at this moment in "time" - at this location in "space"; and, as it may have been 14 billion years ago, or 14 billion years from now, at locations in the cosmos far distant and/or microscopic. at scales subatomic. For, if spacetime is compressible, as posed herein, so is the universe and everything in it, including the reader and all he/she holds dear.
If this were not the situation, then
the scientific narrative of The Big Bang Theory may as well be relegated
to such fictions as Santa Claus and those of Alice's Adventures
in Wonderland & Through the Looking Glass. It is for the reader
and scientist to decide how to proceed.
