SPACETIME (1)
Spacetime is the Einsteinium expression of the MBrane in a dynamic sense (movements in time). Where in General Relativity spacetime is not a realworld event, it is here in our pelastratic approach. Spacetime  as the gravitational brane  is geometrically present in every fundamental particle, multimulti layered in every atom, in every molecule, in every cell.
As in GR ... also pelastratic spacetime 'ripples' or oscillates (waves like a table napkin moves in the wind or like the sea surface). In our concept spacetime is very dynamic. It is in CONSTANT movement. When on certain spots holons are created the local stretchability changes or deforms.
RESTRUCTURED SPACETIME: Restructured spacetime is the local coupling of parts of the MBrane.
Some more information on Einstein view on Spacetime. I quote from the website: http://itss.raytheon.com/cafe/qadir/aphyrel.html :
We really do not know what spacetime is, other than two clues afforded by quantum mechanics and general relativity. General relativity as developed by Albert Einstein, says, and this is a direct quote from Einstein, that "Spacetime does not claim existence in its own right, but only as a structural quality of the [gravitational] field" (from: The Special and General Theory page 155), but Einstein's asserted that spacetime is a fundamental field in nature as an underlying metric (gmunu) to the world which like a cake, supports the frosting which we see as the gravitational field, guv. .... Priorgeometry theory sees "gmunu" as being actually a compound object in disguise; one part being the gravitational field, the other part representing a preexisting and immutable arena of spacetime. Einstein had a strong opinion about the issue of priorgeometry. His choice was that the gravitational field represented EVERYTHING, with no preexisting framework for spacetime. This assumption, as provocative as it seems, is the simplest one consistent with all known phenomena. In a quotation from Abraham Pias book Subtle is the Lord page 235, Einstein once remarked that "...[prior geometry] is built on the a priori, Euclidean fourdimensional space, the belief in which amounts to something like a superstition".
So for Einstein: guv = gmunu.
Now to me there is a difference between the PriorGeometry and the metric. guv ≠ gmunu. PriorGeometry represents the potency of everything. As such it is the unstructured boundary, which is dynamic. Below image shows a possible shape. The essence is however a continuous oscillating surface.
The source of the dynamics is  actually  unknown. We judge dynamics to be a property of the system because we observe various forms of dynamics in daily life and in experiments. The boundary is the gravitational field or spacetime.
Once two parts are coupling (one being an active and one a passive part) a double layered new local 'discrete' zone is created. (see creation of holons).

A human observer/participant or instrument will judge such local zones (quanta) as being matter if there is sufficient density (inside layers).
The PriorGeometry dynamics leads to dual building blocs (quantum packages).
Spacetime  as Einstein's gravitational field  represents everything ... without a real framework (since it is pure membrane chaos). Couplings of membrane create locally nonchaos : discrete zones with (relative) stabile structure.
So 'gravity' is intrinsic. It is thus omnidirectional. The observer will appreciate it as push or pull depending from his position relative to the event and his side of the brane. In the image on the left the blue observer can not notive the red event, but might observe a 'strange' (gravitational) push and/or pull effect.




This image was shown on Greene TV show, but it doesn't explain how those marbles are created. The illogic in this concept is that there is a schizoid split between an object and it's gravity properties. Why do the objects have not their gravity inside/embedded? Indeed wherever the object goes the gravity is all the time a part of it. 
One of the fundamental WRONG approaches is the expression: "Matter creates Gravity". Matter is gravity. Next image explains that.
Above image is included in a pdffile (webpage). In this image I show how the holon A(b) is moving into the direction of the Dgroup of holons. The Dgroups has a lot of deformations in the spacetime pillow. This zone is highly materialized. (much layers = much mass).
Now there are two effects:
(1) While the DGroup grows (additional pelastrations) the A(b) holon moves towards the Dgroup zone! The reason is very simple: growth of the Dgroup USES surface of the spacetime pillow between the group of holons and the single holon.
To an observer this will be like A(b) is BEING ATTRACTED by the 'heavier' Dgroup!
(2) When the Dgroup moves (you tear on the spacetime pillow or you move the group or one holons of the Dgroup ) ... also the single holon A(b) will move immediately in the direction in which the denser matter Dgroup goes. Isn't that the effect what we call GRAVITY?
So the more holons (cf. knots) we make in spacetime pillow the higher the local 'density' (or mass) and the more 'attraction effect' (on less massive holons) we will measure. We call that attraction gravity.
That's why gravity occurs ... .
In my approach spacetime can locally double, triple and combine in many ways ... making discrete quanta with extra spacetime layers and unique properties.
Gravity is just an expression of causal con'sequences'.
Space + time really exists as a real dynamic boundary. You can even call that the boundary of the singularity. Matter and light become then restructured singularity or restructured spacetime.
Some traditional links on spacetime and related phenomena:
Is Energy Conserved in General Relativity? by Baez gives you a good idea what parameters are involved in General Relativity.
One of the predictions of Einstein's general theory of relativity is that local spacetime is twisted by the rotation of the Earth. Hans Thirring and Joseph Lense called this "framedragging" any rotating mass will drag the local spacetime frame of reference with it. A link on this. Here a simple and sweet explanation with honey.
