Newston's first law, known as the inertia law: Any object in constant linear motion remains in constant linear motion unless acted upon.
Light rays, and all electromagnetic waves, are moving in constant linear motion and have no mass; constant linear motion needs neither the objects nor their inertia to move energy along. Gravimotion's first law: Any constant linear motion continues acting on its own in a constant linear motion unless acted upon.
The 2 words object in disappeared; Gravimotion's first law introduces a fundamental fact: massless constant linear motion is moving on its own that is a live entity.
Motion is occurring as a real entity moving itself in case of light rays.
The motion of an object relative to you an observer at rest on Earth, is furthermore relative to Earth's motion; and Earth's motion, in turn, is relative to the Sun's around which it is revolving; now through our Milky Way galaxy the motion of that object ends up being relative to the Universe, which in science is expanding or in motion (See Note 1). No matter relativity's accomplishments, the Universe's expansion is defeating the concept of position.
In gravimotion the concept of position is dismissed, light's absolute speed instead is chosen for reference.
The slower the motion of an object (the closest to light's speed) the stronger the action. Any material object cannot have zero motion (with respect to light), motion's dynamism is the inverse of a speed.
An object relative motion (unlike an object relative speed) is relative to light's motion.
Even though appearing in both Newton's motion law and Einstein's motion relativity, motion is not considered in science; science's Standard Model of Elementary Particles is shunning motion reality.
As light's real motion infers, motion embodies both science's speed and energy concepts.
Because real, motion is altogether lapsing a duration and occupying a space volume, and is given here the name motion-volume.
Nature or reality is occurring under 2 fundamental entities that are motion-volumes and physical matter.
The motions implementing light's absolute speed are labeled absolute-motion-volumes.
The motions moving objects, being relative to light's motion, are labeled relative-motion-volumes.
Motion-volume graphical represantation
A motion-volume is represented as a volume made of a surface in space extending in time; like a cylinder, a cube or a parallepipede in which one of the 3 dimensions is occurring as a time duration rather than a distance; space and duration are becoming intricately intertwined in such volume.
In the left animation, the cylinder's cross section is moving in space, its length ocurring as a time duration. It is also represented at right as not moving with respect to you, while continuing moving along our human interpretation of time.
As long as not modified by external motion, this motion volume is moving unaffected along the indefinitely renewing finite present; non longer in the past, not yet in the future, it is constantly overlapping itself implementing a volume of the present.
Such motion forbids instantaneous times as used in science; motion is mandating time-duration-space-volume oneness.
Below are two specific motion occurences that of light waves and motion of matter. Light's motion is represented as a fast moving blue cylinder, the cross section of which is the thickness of the blue line. The object's motion is in black, represented as a flattened cylinder, which ends are out of equilibrium with respect to each other.
In gravimotion interpretation, any motion is integral part of the present. And in reverse as shown next, the present is occurring under motions.
Considering motion to be ocurring as a real entity, is the farthest that can be from science's Standard Model in which everything is made of particles; beware gravimotion's motion-volume is not part of science.
Besides should you decide to read about gravimotion, this frenchman's english writing is not the best.
Note 1: Science's accelerated expansion of the Universe is in gravimotion not expanding but occurring as gravity that happens to be accelerated motion in science.
