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 remains in 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 a real entity moving on its own.
Motion is occurring as a real entity moving itself in case of light rays.
Gravimotion's relativity
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.
Gravimotion's motion-volume
Even though appearing in both Newton's first 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
Lacking a better interpretation, 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 duration rather than a distance, space and duration becoming intricately intertwined in such volume; in the animation proposed here, the cylinder's cross section, the area of a radius r circle, is moving in space; the cylinder's length is ocurring as a time duration.
The above motion volume length is furthermore chosen equal to its circumference (length = ℼ . 2 . r ) expressing space time intertwining; the whole illustration from left to right is occurring under 36 consecutive instances of the same motion volume, each time overlapping itself by half its occurring or time length.
These overlapping motions forbid instantaneous times as used in science; they are mandating motion quanta or motion's events remaining alive through the renewing present.
Caution
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.
The above motion volume length is furthermore chosen equal to its circumference (length = ℼ . 2 . r ) expressing space time intertwining; the whole illustration from left to right is occurring under 36 consecutive instances of the same motion volume, each time overlapping itself by half its occurring or time length.
