Summary: Space Time Curvature Gravity of Moving Mass

The linear speed
If the mass doesn’t move, the compression of space will form space time curvature into straight line to the center of mass, as shown by green arrows in Figure A.

Figure A

When mass is moving, the curvature in the front of direction is more dense than the rear. The compression of space in the rear fills the left space. This filling is balance with the density of space compression in front of direction (Figure B). Therefore, the space will keep the mass moving in balance. If the speed of the movement is the speed of light, the compression of space is strong enough to eliminate the existence of mass. That is he reason why mass cannot move in the speed of light.

The Spin of Mass
The spin velocity can be explained like this:
If the mass doesn’t spin of move, the compression of space will form space time curvature into straight line to the center of mass, as shown by white arrows in Figure 1.

Figure 1.

When the mass begin to spin at low velocity, compression of space will be curved as shown in figure 2. This will cause compression of space is stretched and the compression strength decreases. As the strength of compression decreases, we can experience centrifugal force.

Figure 2.

It the velocity of spin is too high, the curve of space-time becomes dense as shown in figure 3. The density of space-time compression can be enough to causes gamma ray burst, or trap the light like the black hole. Finally, the density can destroy the existence of mass to create supernova blast.
