Reality Check, continued:
As regards any question of, 'Why didn't Einstein say gravity is the 4th Dimension'? He did. And categorically. Einstein said and proved that gravity is the 4th Dimension much more eloquently and elaborately; much more absolutely than I or anyone else ever will.

We could reference an abundance of Einsteinian non-mathematical quotes at this time, quotes (many of which are included in this TOTAL FIELD THEORY presentation) - in other words - finding gravity the 4th Dimension. Instead, at this time and in the name of abbreviation, we'll reference what is literally the best-known mathematical formula in the world. The direct, non-mathematical translation of which irrevocably proves - as it always has - that gravity is the 4th Dimension.

The formula is E=MC2. The direct non-mathematical translation of which is: 'Energy equals Matter times the speed of light, squared'.

In grade school as well as jr. high school, I would hear other students ask a question which I have since then learned is also familiar to many others; that question being: "In the formula 'E=MC2', why is C (light; field energy) squared (Out of M < Mass/Matter/ Particle>; which is perceived as a static, non-expanding, non-field)?"

I may have asked the question myself, but I knew less of mathematics than I do now. But others did ask that question, and that is understandable enough. The teacher's (ubiquitous) answer, which I have also learned since then is familiar to many others, was not so understandable. That (alleged) 'answer' being:
'It (C squared) actually isn't necessary'.
This answer, it will not surprise some of you to know, is quite standardized as a response to the question, 'Why is C squared, in the formula E=MC2?'
All are implored not to take my word for this. Simply ask the next physicist or mathematician you happen in to. If you pursue this question, you will get that answer or its equivalent. I had no understanding of mathematics whatsoever, and yet it still left me and many others wondering:
'If in fact it isn't necessary, then why did Einstein include it in the formula?'
If it isn't necessary, why is pi r squared? To find the volume of a circle why square pi r? (Answer: because the circle is 4-Dimensionally expanding, squared. Exactly why you can spend forever carrying pi out to it's 'last' decimal point... Refer, the Golden Rectangle, also known as the Golden Spiral, and 'Phi'.)

One may again reasonably ask, 'What is the speed of light squared from?' Of course the only answer is, 'The speed of light (C - celeritas constant) is squared from (out of) Matter'.
Smoke On The Perrier:
Affixed to that familiar explicit statement made by Einstein, is the familiar implicit statement - 'but it isn't necessary'.

Light energy is acknowledged to be, to say the least, expanding. Specifically, it is very accurately measured, originally in 1887 by Michelson & Morley, to do so at 186,282 miles-per-second.
*Light energy is also acknowledged to be qualitatively identical to *Matter energy; *their differences being only their densities. Light being much more thinly distributed and tenuous than matter. This is proven in the statement 'E=M' of the formula 'E=MC2. Originally published by Einstein in 1906. Light energy or electromagnetism is furthermore acknowledged to invariably originate within and expand-out-of *MatterEnergy - *generator of all spaces and times.


On the other hand, MatterEnergy is not acknowledged to be expanding.
Quite the contrary. Matter is unanimously agreed to be static and non-expanding.


Digressing To Reality, Geometric & Algebraic Law:
In the formula E=MC2 we have the acknowledged dynamical omni-directional expansion of electromagnetic or light energy, squared from presumably static/non-expanding MatterEnergy.

As long as there are those who demand and deny proof of the 4-Dimensional MassField, there will also be those who fail or refuse to recognize the accumulative achievements of historical and contemporary Academic Physical Science - and, the lessons of Algebra 101.

If all the Nobel laureates in the world gather together to agree that any entity acknowledged and agreed to be dynamically expanding, can be algebraically squared from any other entity which is agreed to be static and non-expanding (exactly such a gathering exists, and has existed since 1906):
what is established in such an assemblage of authority is that, none among these mortar-boarded multitudes has possession of the mathematical ability required to pass the seventh grade.



Einstein's 'renowned formula' E=MC2 proves again that Universal Matter is literally, constantly and dramatically expanding.
Clipping right along on this planet at 32 feet per second squared. The Causative Source of the 4-Dimensional Space-Time Continuum: a dimension of time, and motion (are synonymous - time being the interval between two or more events <in space>).

The bespectacled scientific malrepresentatives proclaim with all professionalism, that their 4-D spectacles are unfindable. That their sensory optical prescription is immeasurable. Unrefractionable. Even unimaginably out of sight. The 4th dimension: officially proclaimed to be nowhere in the measurable light, or the sensual realm of touch, taste, hearing or sight. In or out of italics and/or parentheses.

(Big Brother can't find the 4th dimension anywhere, 'because humanity is not four dimensional'. 'Awwwk! Humanity is not 4-dimensional! Awwwk! ' A rare consensus solution to the 'three body problem', in the lean agreement between the beefy non-sequitur and the bullish oxymoron, whereas, 'Two wrongs don't make a right, but, three or more do.'

Mr. Science is out to isolate gravity waves. Dr. Graviton Livingston is attempting to locate someone who presumes enough to find himself, and what he vacantly purports to be in search of. Lost on the North African river of denial. The Star Optometrist has contracted a posse with Warner Brothers to polish-off both lenses on his misplaced WANTED: Dead Or Alive spectacles. Housing the famed and framed rear view mirror with the accumulating police cars in it. Speeding - ever accelerating - from resolution and safety, at way over 31 m.p.h.

Disregarding:
the descent of free falling objects, the weight (and inert mass value) of everything from apples to leaping blue whales; the orbiting of the planets - and all other orbits, logarithmically spiraling, with and without punctuation.
