## Absolute Motion

##### Reference: A Logical Approach to Theoretical Physics

Absolute motion is motion that does not depend on anything external to the moving object for its existence or specific nature. Thus, the motion that qualifies being absolute is acceleration. Acceleration is the change in velocity relative to the velocity of the object. The velocity of an object relative to itself is always zero.

But there is a motion (speed) that is intrinsic to an object because it depends on the density of the object. A substance can be atomic (such as, matter), or non-atomic (such as, light). [See Matter, Light and Substance]. Any substance, whether it is a particle or a quantum, has the property of density. [See Particle, Quantum and Density].

The higher is the density of a substance, the greater is its duration at a location. For example, matter that has a very high density can endure for a long time at a location, whereas, light that has almost infinitesimal density can hardy endure at that location before it moves away.

The intrinsic motion of the substance is reciprocal to its duration at a location. Therefore, we can say, the higher is the density; the lower is the intrinsic or absolute motion of substance. The following sketch gives an idea of this relationship.

Since density is three-dimensional, but motion (velocity) is linear, we may say:

Intrinsic or absolute motion = constant / cube root of density

If the density of the substance is not changing then its absolute motion is not changing either. This explains the Michelson-Morley’s Null Result. Since the density of Earth and light is constant, the difference between their absolute motion is also constant.

The change in the direction of movement of earth shall not provide different velocities of light.

This also explains why atoms agitate, which leads to Brownian motion. Atoms have intrinsic velocities and very low momentum. When a number of atoms are in close vicinity, they continually collide because of their inherent motion.
