There is no acceleration in gravimotion.
Gravimotion's equivalent of acceleration is uniform motion to which more uniform motion is combined.
Uniform motion only, exists or occurs in gravimotion.

A basic uniform motion is called a motion-occurence.
Activity is the name given to a number of individual motion-occurrences acting in a concerted way or in a social type of behavior.
Activities involve either the direction (called inclination) of a number of motion-occurrences or their agglomerated density.
Here are 7 types of activities:

1. Pure activity: space-time.
2. Confined activity: temperature.
3. Radial activity: gravitation.
4. Coordinated activity or gravimotion: motion of matter.
5. Acclivity: positive electric field.
6. Declivity: negative electric field.

Pure activity and confined activity are even density activities (no variation in density), the motion-occurrences forming them having any kind of inclination.
Both radial activity and coordinated activity involve specific inclinations of the motion-occurences forming their assembly.
Acclivity an declivity involve densities within packs of motion-occurences. An acclivity is a density of motion-occurrences above the pure-activity density, a declivity is a density below pure-activity level.
Waves are a specific case of acclivity, declivity variations. In gravimotion, light waves format pure-activity (a cousin of physics' quantum jitter) just as sound waves format air molecules jittering motions.

The big bang, now a fact of life in science physics, is questioned and refuted in gravimotion.

1. Big bang is fact of life in physics
   This item "big bang" has been added on April 26 2010 to this lexicon, after the author watched the April 25 2010 8pm (Pacific time) show: "How the Universe Works" on the "Discovery Channel".
   In that TV Show, Prf. Lawrence Krauss (Theoretical physics) asserts that big bang occured as a minute point in a minute amount of time and in an infinite amount of energy.
   All details were provided with other Professors such as Michio Kaku (well known for its media appearances), proving in the eyes of this writer that "expansion of the universe" and "big bang" are now "fact of life" in the science of physics.
2. Big bang never occured in gravimotion
   This item "big bang" has been added here to this lexicon, on this date (April 26 2010), because in the book "The Harmony of Reality, in no Time..." (released 2 years before) the concept of big bang was taken for granted and conveniently used for specific purposes.
   Thinking of it since, the author discovered an elegant way to:
   • Integrate (in the sense of unify within human mind) both phenomenon of universe expansion and gravitation.
   • That integration gets rid of dark energy, which remains a mystery as it has not been discovered physically yet.
   • This gravimotion's new point of view is going counter current to physics claim 1. above, and is claiming instead that both the expansion of universe and the big bang are no longer needed.

The confined-activity is the overall result of the chaotic motion of the molecules of a material body (or gas).
Confined activity is interpreted by our human body as temperature.
Confined activity doesn't produce any overall motion of the body.

The coordinated activity is the motion of the molecules of a material body (or gas), and coincidental to the overall motion of the body.

Dynamic in the gravimotion world expresses the reality of motion while in action.
The conventional meaning of the word "dynamic", found in dictionaries, relates more to force than to motion.
But force, in gravimotion's interpretation of reality, is an abstract concept that doesn't exist in reality.
Only motion exists in gravimotion.
In gravimotion no distinction is made between kinematics (study of motion occurring without force) and dynamics (study of motion occurring under the influence of force). Kinetics in science also concerns both aspects of motion, yet instead of merging the two into one entity as done in gravimotion, kinetics keeps force and motion separate.

An electric aura is the equivalent of physics electric field that surrounds any electric charge.
The word "field" belongs to the science of physics though.
An aura differs from a field in that it is made of dynamic motion, which is not the case of the field in physics.
Electric auras surround single charges (electron and proton) as well as compounded charges (ions made of several protons).
These auras extend beyond the electric-charge they are induced by.
A proton induced electric aura, called acclivity, is pure-motion (space's pure-activity) of higher density than surrounding pure-motion (space); and an electron induced electric-aura, called declivity, is pure-motion of lower density than surrounding space's pure-motion even density.
The auras that surround electric-charges are "transparent" to matter (or to the atoms that make matter). That is, these auras are not solid and the atoms of matter can penetrate their territory (just as matter penetrates electric fields in physics).
The electron and proton in an hydrogen atom are so close that their induced electric-auras form a solid-plasma, which differs from their individual auras in that it is solid and cannot be penetrated by foreign matter (other atoms).
An ion made of an atom with a number of electrons not equal in number to the number of protons, also induces an electric aura.

In gravimotion a subatomic particle has no mass and no electric charge; both its electric aura (either acclivity or declivity) and radial activity make one, and that one assembly formats all of physics mass, electic charge, surroundings gravitation field and electrical field.
The radial activity (gravitational field) of a subatomic particle is not issued from mass (which doesn't exist) but is coincidental to space's pure-motion-occurrences inclinations.
The electric aura of the particle is coincidental to the density of the very same motion-occurrences that make radial activity.

As mentioned above (in Electric aura) electric charges do not exist in gravimotion.

Force doesn't exist in gravimotion.
The equivalent would be "restricted motion".

The gravimotion of an object is the object's radial-activity but out of equilibrium.
Gravimotion is graphically radial activity that lost its symmetry.

In physics the word integrity has a very precise mathematical meaning (Noether's Theorem).
In gravimotion's interpretation of Nature "matter integrity" is interpreted as the fact that matter doesn't (very likely) desappear when it is moving from a position A to another distinct position B.
In the science of physics, because the "positions" are fundamental and the "motion" that occurs in between two positions is not, the integrity of matter can be ignored, while motion occurs.
In gravimotion the motion that occurs between positions is fundamental and as such matter has to remain in existence while moving in between two positions.
The integrity of matter in gravimotion involves the "occurrence" of matter over time duration (and not at successive times) that is matter in motion "occurs" at time B while it still occurs at time A.
The integrity of matter in gravimotion mandates that matter occurs during durations of time longer than instantaneous instants, and that matter elongates in stretches of space volumes larger than the volume we think it occupies at rest.
Both gravimotion's integrity of matter (incompatible with inert mass) and motion (incompatible with physics concepts of space and time) cannot be explained with physics concepts of time, space, time-instant, position-in-space and inert-mass.

Mass is not a word in gravimotion.
Mass doesn't exist.

Motion is everything in gravimotion interpretation of Nature.
Space is made of motion (but not the same as physics' expansion of the universe).
Gravitation is motion (free fall).
Light rays are pure motion (translated without mass).
In the gravimotion interpretation of nature a subatomic particle (electron or proton or any other real particle) is itself made of motion!
As such instead of occupying successive position in time as described in physics, a subatomic particle very constitution occupies altogether several distinct positions (as defined in physics) over a finite duration of time.
In gravimotion interpretation of Nature a subatomic particle "extends" over space and "stretches" in time, which amount altogether to its motion and constitution.
While motion is evident and mundane, motion is unfortunately impossible to explain with current human concepts of inertia, space and time!
As such:

• Either we deal with motion because we feel it exists in reality and then inert mass, space and time must be dismissed (gravimotion's choice)!
• Or we deal with inert mass, space and time (or space-time) while motion, which is incompatible with these concepts is considered not to exist (physics choice).

Because motion is physically evident while space and time are not, and even though mass seems to be, this author's interpretation of Nature is made in terms of motion rather than inert mass space and time.
Inert mass, space and time are all out of consideration in gravimotion interpretation of nature.

In physics motion is described as successive positions in function of time.
Amazingly in physics these positions, time and distance only are considered, the motion that occurs in between positions is not considered!
In physics there is also the concept of speed.
Speed is the ratio of a distance (and that distance has nothing to do with the motion that occurs over it) and time (that doesn't contribute to motion either).
Speed doesn't provide a clue about the motion that occurs!
Clearly motion is ignored in the science of physics!
Worse at the quantum scale, and in virtue of the uncertainty principle, the very concept of position disappears in physics!
Besides ignoring motion physics blurs its own description of motion within our minds!

The motion-quantum is real in the sense that it is a finite motion, unlike the infinitesimal (that has no size) mathematical concept.
This motion is nevertheless indivisible in smaller units.
A consequence of this indivisibility is that the motion-quantum fuses time and space, which become indivisible!
The motion-quantum is the smallest motion quantity that exists.
The motion-quantum is also called space-quantum and resident-motion.

The motion-volume is the geometrical representation of motion in gravimotion's interpretation of nature.
Motion is "physically" observed and "physically" felt, and not explained.
The graph or model represents "a motion", which could be the motion of your own body in your car, during a tenth of a second.
In this particular representation the subjacents motion of your body, which are the spin of earth and the motion of earth around the sun, are not represented.
And these two are non negligible: 1,000 km per hour (at the equator) and 100,000km/hr respectively!
As such the model represents only your motion in your car.
The continuous curbed line on the right indicates the direction of motion.
The broken line on the left indicates that motion implies a finite duration of (our concept of) time as well as a finite stretch of (our concept of) space.
The elongation of the motion-volume coincides to the motion intensity (that would be the speed in physics).
The more matter in motion the more motion-occurrences of same intensity and direction are at play.
Even though physics' speed has been mentioned (above in parenthesis), the motion-volume has nothing in common with speed.
Speed is relative that is defined with respect to a reference system. The motion-volume characteristics are internal (more like force in physics) and do not relate (are not relative) to anything external.
In addition, a motion-volume is not expressed in terms of distance and time as speed is. The motion volume is expressed in terms of intensity and direction.
A simplified model of the motion-volume is made of a single straight line ending in several segments decreasing in length, and is easier to use.
While this simplified version of the motion-volume is used graphically, the abbreviation MV is used both in the language and written text.

Even though motion is mundane, one must surprisingly make "abstraction" of the "abstract" concepts of position in space and instant in time to accept (within one mind) the reality of motion!
Should you try to make the mental effort and "accept" mentally the reality of motion, you will nevertheless not be able to logically describe motion using our current concepts of time and space.
As of today our human brains are "only" able to accept motion as coinciding to reality!
With our concepts of inertia it is extremely difficult (actually impossible) to imagine that we are living "durations of time" rather than at some successive instants in time.

The active offset is an internal modification occurring within the motion-volume.
As a reminder, radial and skewed activity have the same focal point.
When the active offset is occurring, the focal point shifted-off that common position.
The offset of the focal point occurs in the direction of the motion.
The active offset (internal format of gravimotion) is the last step in setting an object in motion, which steps are as follows:

• Radial activity (absolute rest)
• Skewed activity (added motion, but not allowed to take effect)
• Active offset (motion takes place)

The active offset, extern sign is that the object is free to move and is in motion (gravimotion occurrence).

Physical: that, which belongs to the universe, or that, which occurs outside the human mind.
In physics' science, the physical can be inert (mass) or dynamic (force).
In gravimotion interpretation of Nature, everything is in motion or "is motion", inert doesn't exist.
As such, all of the physical (the universe and its contents) occurs in the motion format.

Pure-activity, in the gravimotion world, replaces our concept of space.
Pure-activity is a compounded activity made of:

• Confined activity, coincidental to the "temperature" of space.
• Coordinated activity, coincidental to the expansion of the universe.
• Coordinated activity, coincidental to the spin of the universe (necessary in gravimotion).
• Pure activity is also radial activity, that we experience as force of gravity.
• In the gravimotion theory, the above radial activity is sufficient to explain Hubble's red shift.
  The universe is not expanding in gravimotion interpretation of Nature.
  Click: Gravity-frequency shift.
• Pure activity is also of type electrical aura, in view of its mere density.

The radial activity replaces physics gravitational field.
The radial activity is made of motions oriented toward the center of gravity of the object around which it is located.
Unlike physics' force of gravity, radial activity doesn't extend to infinity but is limited in pure-activity (space).
Radial activity is symmetrical in all directions.
Radial activity doesn't make the object move.

Resident activity is also space's pure-activity.
Resident activity is to pure-activity what physics' quantum vacuum is to space.
In adition the resident-activity is curbed, restrained to move locally only. It cannot escape very far.
While moving around frantically, resident activity does so within a restricted scope (motion scope).

As a reminder radial activity (physics' gravitational field equivalent) is symmetrical in all directions.
Active skew is radial activity that lost it's symmetry, it is skewed.
Active skew refers specifically to restricted motion, though. This is the motion of our body while standing on earth: we feel the motion under our feet, but do not move due to the barrier that the surface of earth offers to our body.
There is incompatibility between physics force of gravity and gravimotion's motion under the format of active skew.

The solid plasma is a specific combination of electric-auras (electromagnetic fields) that occurs in atoms.
The combination makes the solidity of the atom, also called the integrity of the atom in gravimotion.
Within an atom electrons and protons are intertwined in a whirling dance that metamorphoses their surrounding auras into a solid plasma.
The proximity between electrons and protons, in an atom, render their motion even more frantic.
And the more the animation the more solid.
This solid plasma is limited to the inside of the atom when the number of electrons equals the protons. From outside the atom is neutral, just as mass is in physics.
Whereas mass occupies only a negligible volume of the atom (the nucleus) in physics, gravimotion's solid plasma spreads throughout the entire volume of an atom.
Very strong electrical fields also exists in physics within the atoms.
In gravimotion though the solid plasma is self sufficient, there is no mass inside the atom. In gravimotion mass doesn't exist.
The solid plasma is the name given to the solidity of the atom in gravimotion.
Because electric auras are made of motion, solid plasma is made of motion, only more dynamic and perfectly orchestrated.

Space is a word which is used in conjunction with motion in gravimotion: space motion quantum. See motion quantum.
The concept of space as interpreted in physics doesn't exist in gravimotion though.
Space is replaced by motion in gravimotion's interpretation of Nature. See pure-activity.

Time doesn't exist in gravimotion.
The equivalent of time in gravimotion would be the direction of motion.
Should it exist time would be a scalar (just as energy is in physics) in gravimotion.
Time is a word not used in gravimotion. Time doesn't exist.

In gravimotion interpretation of Nature a volume is not "geometrical" but made of motion, and given the name motion-volume.
Because motion has no beginning and no end, besides being physical, a motion-volume has nothing in common with a geometrical volume.
Unlike the geometrical volume of a cube or a sphere, a motion-volume has no well-defined sides or boundaries!
Space is made of motion, and a volume of space is a motion-volume.
A unit volume or motion-unit has yet to be defined in this gravimotion theory (in its infancy), and could be expressed in terms of motion-quanta.
