A quote by Sir Isaac Newton:
“Gravity must be caused by an Agent acting constantly according to certain laws, but whether this Agent be material or immaterial I have left to the consideration of my readers.”

Mainstream science maintains that gravity is the result of the warping of the geometry of space surrounding a three dimensional mass. This is called the gravitational field. Exploration of the nature of gravity and the direction in which the vector orientation of the displacement delta of gravity exerts it’s effects should be focused on the geometry of space not the mass itself. The phenomenon providing the displacement delta for gravity is in the geometry of space, not in the mass. The arrow depicting the vector orientation of the displacement delta of the position,velocity, acceleration, and direction of a mass affected by gravity from the origin to the point has to be oriented in the direction FROM the warped space (origin) TOWARD the mass (point) because that is the direction of the displacement delta. The 180° change in the direction of the vector orientation of the displacement delta of gravity from an attractive displacement delta to a repulsive displacement delta is a discrete global symmetry. At the surface of the Earth the source of the displacement delta due to gravity is from space (in the warped space or gravitational field) which means that it has to be a displacement delta pushing down from above. If the displacement delta was a pulling force, of which the displacement delta is in the warped space, objects would be pulled upward!
Space exists not only in space but at the surface of the earth and space also exists within the earth among the electrons, protons, and neutrons of atoms. This is true of any material object in existence. Gravity or expanding space affects every single subatomic particle in matter and in turn is affected by every single subatomic particle in matter. Each subatomic particle produces, in addition to the electromagnetic and nuclear forces, a slight gravitational warping of space surrounding it. The warped space then expands outward in all directions.
Space does not expand out of a “black hole” so that the interior is subjected to the crushing force of expanding space from all directions with no counteracting expansion neither from the interior nor from the other “side” (“side” being spherical).
Gravity as a pushing displacement delta is more plausible than as a pulling displacement delta. Looking at the possible sources of gravity one finds two possibilities:
1) That there is a displacement delta emanating from 3D objects which pulls 3D objects toward each other.
2) That there is a displacement delta embedded in the warped space surrounding a mass which pushes another mass towards it. In effect both masses are pushed toward each other.
Considering the latter, the repelling displacement delta of gravity is present everywhere from every direction so that a single object in space which is not near any other object is held in the nonwarped geometry of space and is seen to simply be floating in space (comments on moving matter below). The repelling displacement (gravity) is equal in all directions as long as there is no other object nearby. When another object is nearby there is an imbalance in the geometry of space (warped space). The imbalance is a result of “absorption” of some of the energy of the repelling gravitational displacement by the matter of the objects. Not all of the repelling gravitational energy is “absorbed” and passes through the objects exiting the other “side” creating a counteracting gravitational “shadow” (warped space). The amount of “absorption” is proportional and depends on the mass of the objects producing the equivalence principal of gravity. A three dimensional spherical gravitational “shadow” of the repelling displacement surrounds both objects in all directions (warped space). In a line connecting the two objects there is less repulsion on the inside between the two objects than on the outside since they are in each others gravitational “shadows”. The two objects are pushed toward each other. The 180° change in the direction of the vector orientation of the displacement delta of gravity from an attractive displacement to a repulsive displacement is a discrete global symmetry which changes neither the equations nor the calculations which are already well established.
Displacement J produced from time t_{1} to t_{2} is defined to be
where F is the resultant displacement applied from t_{1} to t_{2}.

F is the displacement acting on the masses;

G is the gravitational constant (6.674×10^{−11} N · (m/kg)^{2});

m_{1} is the first mass;

m_{2} is the second mass;

r is the distance between the centers of the masses.
Matter is obviously physically connected to gravity and therefore physically connected to space.
Matter exists in the dynamically expanding environment of space. Space is not a static environment. The expansion of space is isotropic and occurs from every point in empty space (tensor field). It becomes anisotropic (warped space) in the area of space where matter exists. This anisotropic condition of expanding space surrounding all matter (gravitational field) causes the effect known as gravity.
The expansion of space causes the effect known as gravity! Gravitational acceleration occurs as two objects approach each other. They “see” less and less of the pushing displacement from the outside which is not between them because of the angle between the horizons of both objects as well as the fact that there is less and less space expanding between them. The effect is that of a deepening spherical gravitational umbra (warped space).
The Multiverse
Every point in space is at the center of it’s own universe and is isotropic.
Tensor Field
Imagine a stick figure representation of space using rays in space emanating from a point in every direction spherically. Now imagine rays emanating in every direction spherically from another nearby point in space . The ray lines which are between the two points will crisscross. Now imagine this happening at every point in space with lines emanating spherically from every point in space. Now we have an unimaginably complex geometry of spacetime. Spacetime is expanding from every point in space so that there is a dynamic delta in the geometry of spacetime.
The still image below illustrating the single body warpage of spacetime has to be viewed with the concept in mind that this still image depicts the motion, from left to right, of an object (not seen) at the center of the “doughnut”. The larger area at the “rear” depicts the stronger gravitational displacement. The lesser displacement area at the “front” of the moving object is overcome by the stronger displacement at the “rear”. The “change” is occurring in the expansion of spacetime. When the initial displacement giving an object acceleration is removed the object then “coasts” on the warpage momentum of expanding spacetime.
The center of the single body warpage (doughnut) is where the warp field umbra of any object (elementary particle, subatomic particle, atom, micrometeoroid, ship, asteroid, planet etc.) interacts with the dynamically expanding motion of spacetime. The size of the object’s warp field umbra is proportional to the size of the object. In the image, the grid lines of both the spacetime and the warp field umbra are not static but are expanding in three dimensions from every point in space. The warp field umbra (doughnut) created by the object is moving with the object. In this process mass plays a “catalytic” role and is not the origin of gravitation.
As a 3D object exists in space it causes the space surrounding it to become anisotropic. This anisotropic, or warped space, surrounding 3D objects is commonly called gravity. Warped space should not be confused with the dynamics of spacetime within which warped space acts. In the analogy of the trampoline and bowling ball, the trampoline is spacetime and the depression in the fabric near the bowling ball is warped space. Gravity is not a pulling displacement. Gravity is a pushing displacement! This 180° change is a discrete global symmetry. Matter “absorbs” the gravitational energy from the expanding space in the universe and creates a gravitational “shadow” surrounding the mass spherically in all directions. The pushing displacement of gravitational energy is not completely “absorbed” by matter. The proportional variability of “absorption” explains the variability of gravity or the equivalence principal with respect to varying masses. The greater the mass the greater the “absorption” and the lesser the mass the lesser the “absorption”. The gravitational energy which is not “absorbed” passes through the mass and partially counteracts the pushing displacement coming from the other direction. Two objects in the vicinity of each other, each having a gravitational “shadow”, are pushed toward each other. As they approach each other the gravitational “shadows” intensify and the result is increasing gravitational acceleration. An object in free space not close to another object receives an equal amount of gravitational energy from all directions and therefore stays suspended in space and obeys all of Newton’s laws of motion as well as Einstein’s concept of spacetime. The 180° change in the direction of the vector orientation of the displacement delta of gravity is a discrete global symmetry. It is much more logical to assume that gravity originates from the limitless depths of the universe than to try to imagine some force emanating from matter which pulls other matter towards it.

Gravity is considered to be a “weak” force compared to the other forces of nature. I beg to differ. Gravity only seams to be weak because matter extracts energy for the displacement delta proportional to the mass of the object (equivalence principal). Witness the mass of elementary particles! The crushing gravitational force in a black hole exhibits the true force of gravity.
Gravity as a repelling displacement delta explains the voids and alignment of galaxies in the macroscopic universe.

Gravity & Electromagnetism UNIFIED
I hypothesize that gravity and electromagnetism are a unified system with EM waves being carried forward along with the expansion of spacetime (gravity) at the speed of light.
The 49 second video clip of a computer simulation below illustrates that the expansion of the geometry of spacetime (gravity) carries forward the propagation of electromagnetic waves.
The video below is the complete lecture which includes the video clip above at time stamp 00:16:15 minutes which shows a computer simulation of EM wave propagation.
My hypothesis adds to the lecture in that the seemingly static structure depicted when the charge stops is actually gravity, in other words the expansion of spacetime
