In "Philosophiæ Naturalis Principia Mathematica" Newton wrote that the equations he provides had to be correct as they match physical measurements. He insisted though that he was telling us nothing about the basic nature of gravitation. And because we ignore the basic nature of both space and time, Einstein's space-time equations tell us nothing about the basic nature of gravitation either.
Because free-fall is motion, the fabric of gravity is motion, hence the word gravimotion.
Gravimotion is an accelerated motion toward a center of gravity matching and implementing physically science's own gravity accelerated motion; in gravimotion interpretation of Nature, science's force of gravity becomes a restricted motion felt by your own body under your feet when you are standing up.
Physics equations concerning light (called electromagnetic fields in science), which do match physical experiments, have to be correct. Yet again physics' mathematics provides no clue as to the physical constitution of an electromagnetic field; we human have no idea on what distinguishes in space the physical entity that is behind a gravitational field from the physical entity that is behind an electromagnetic field.
Because light is moving and has no mass the fabric of light is pure motion in gravimotion interpretation of Nature.
And light's pure motion is moving uniformly; it is the maximum motion that may occur, and that pure motion is travelling in straight lines when not deviated by a mirror for instance.

1. Based on a single ingredient that of motion only, gravimotion unlike physics is a unified interpretation of Nature. Considering their fabric that is pure motion-activity, both light and gravity are united in a grand unified manner; by contrast the conventional scientific interpretations of light rays and force of gravity are 2 distinct and foreign entities having no common ground whatsoever.
   
2. Gravimotion, which is based on motion, rests on bare reality. Did you ever ask yourself what the string of the string theory could be made of? Unlike physics' mathematical string, which is referred as either a vibration or a frequency or a string or recently a membrane, motion is real; anyone knows what motion is.

Gravimotion's interpretation of Nature departs from the conventional interpretation given to physics mathematics.

Here are 2 thoughts departing from conventional interpretation:.
Because motion takes over everything, rather than living in time, in gravimotion interpretation of Nature you and I are living in motion the present mo(ve)ment!
Then no matter how fast or slow, because it distinctly occurs, the present mo(ve)ment is finite; yet because the present mo(ve)ment renews itself over and over, because it has no beginning and no end, it is infinite; the present, which occurs outside our minds, unifies (outside our minds) these 2 incompatible mental concepts of ours that are finite and infinite! In gravimotion interpretation of Nature the finite and the infinite make one.
In this treatise the meaning of the word motion is consequential, among other things, to Einstein's time dilation or to the discovery by Einstein that time is not universal as explained next.
The time given by any clock, rather than flowing at a rate shared by all clocks of the world, is instead dependent on that clock's motion relative to the observer looking at it. When a clock doesn't move with respect to the observer looking at it, it runs at the very same rate as that observer's own wrist-watch; should that clock be embarked in a plane, fly away and back, that clock then provides the observer a different time than that of its wrist watch.
Physical experiments corroborate above succinct description concerning the time dilation theory; time is dependent on motion (called relative speed in science and experiments).
Unfortunately the definition of speed (relative speed), motion's archetype in science, has been defined prior to Enstein theory in the opposite way!
Speed, in the formula: v = distance/"time unit" (any number of miles or kilometers per "hour"), is a function of time .
In the real world it is the opposite, time is a function of motion, motion rules time! In my opinion the concept of speed is inappropriate and in all of this treatise I use the word motion and shun the word speed; this is my way to put aside the inapropriate conflict that exists between our human concept of relative speed and the reality of motion.

In addition there is an interpretation of time dilation disconcerting by its simplicity yet not mentioned in science; whether mechanical or atomic, there is always a clockwork mechanism running within a clock.
For a moment please make abstraction of the time given by a clock and consider that a clock is but a clockwork that is nothing else than a mechanical or electrical or atomic motion mechanism internal to the clock; my interpretation of these time dilation experiments is that the motion of the plane that carries the clock under investigation alters the very internal motion mechanism of that clockwork rather than time.
As a general rule, in gravimotion interpretation of Nature, a larger motion may alter a lesser motion embedded within it; motion has the ability to accelerate/decelarate motion.
In science force and not motion creates acceleration; in science speed is but a mere effect of force; both appellations relative-speed and motion-relativity bolster the elusive aspect associated to motion in science.
In gravimotion interpretation of Nature motion is real and has thrust; gravimotion's motion is a remote cousin of our mental concept of momentum.
Motion, in gravimotion interpretation of Nature, dislodges then abolishes our human concept of force and abolishes also our human concept of time.

By the way a nice byproduct of this interpretation, in which time is replaced by motion, is that our human concept of time is now part of that grand unified interpretation introduced above.
Space, gravity, light rays, time and Einstein's space-time are observations and concepts, which in gravimotion interpretation of Nature are all occurring under an identical fabric that is motion activity.
