Quantum Space
Empty space as a complete absence of anything has not been proven. Space is essentially the motion of energy. Motion explores how objects move, the acceleration, and the speed. The study of motion is essential in understanding the forces and energies that causes changes in space.
Quantum Gravity
Einstein said gravity is not really a force of attraction between all objects with mass, as Newton thought. Gravity is a result of the warping of spacetime, which makes up the spacetime fabric. He theorised that the effects of gravity are the same as the effects of acceleration, leading him to conclude that gravity is not a force but a manifestation of spacetime curvature. He developed mathematical equations to explain and describe how energy and mass curve spacetime.
Quantum Time
The effects of time are the same as the effects of speed, leading to a conclusion that time like gravity is a manifestation of space-energy curvature.
Relativity is the relationship between space, time, gravity and energy. Relativity states that space and time are relative, and all motion is relative to frame of reference. The laws of physics are the same for all observers independent of their motion. Relativity states that mass and energy are relative and are different forms of the same thing. Mass has infinite kinetic energy and when it approaches the speed of light it has infinite mass. In reference to the energy equation, squared is the variance of mass to energy ratio. In relativity unification, squared is the variance of gravity to time ratio. For example, a very small amount of energy may be converted to a very large amount of energy. Equally, a very small amount of gravity may be converted to a very large amount of time.
