"What do you mean by the acceleration of light?"
One answer is that there was a choice for Einstein to either have light accelerate or to have time accelerate. He relied upon the constant measure of the speed of light being C and arrived at the conclusion, with the leadership of Minkowsky, that time instead accelerates positively and negatively.
"Do you mean that light can 'remain at rest' and 'get accelerated to infinite speed'?"
Light is never at rest. Its velocity varies. It always has a velocity; and, it always measures locally as the speed C.
"Or is it that the speed of light remains within a maximum and minimum limit? If it remains within certain limits, has it a normal speed?"
Theoretically there is no maximum value for the speed of light. If we here on Earth could remotely measure the actual speed of light in other locations then, assuming that the Universe is expanding, we would see the speed of light increasing with no limit unless the Universe can't expand to infinite size.
I wrote this in my message to Steven:
The empirical evidence of electrical type effects demonstrates that there is a cause of polarity and it is connected to particles of matter. Electrons will voluntarily move toward protons. Electrons will voluntarily move away from other electrons. The effect named polarity, as with all effects, must be caused by the primary cause. The primary cause is the variation of the speed of light. I have already used, for the purposes of defining the size of the hydrogen atom, the idea that electrons cause a positive exceleration of light and protons cause a negative exceleration of light. There is, therefore, a natural polarity of the change of velocity of light. This is the starting point to begin theorizing the polarity of electrical effects.
The effect we measure as the mass of a particle is detectable almost solely within the length of a single photon. Beyond this distance, the particle's effect becomes greatly diminished. What have been known as charged particles are high and low points in the continuum of space or, as space can more accurately be defined, are high and low peaks in the continuum of the control of the speed of light. They are high and low points in the speed of light. Their overlapping effects are what I have defined as the background light-field. I will use this visual aid again here. The background light-field is a relatively constant speed of light. Its mostly minor variations are measured as the effect we call gravity.
I picture electrons as the high peaks and protons as the low peaks with respect to the background light-field. Since electrons and protons are attracted toward each other, I anticipate that there is something about the polarities of their excelerations of light that causes this attraction. If this is the case, then it implies that the variation of the speed of light is one of two fundamental aspects of the universe.
There are, it seems to me, two causes of change in the universe. There is, of course, the variation of the speed of light. The first aspect is that there are permanent sources of a change of velocity of light. These sources are called particles, and they guarantee there will always be variations in the speed of light. The second aspect is that light acts to neutralize variations in its speed. The movement of an electron toward a proton accomplishes a minimization of their individual effects upon the speed of light. In other words, their opposing effects increasingly overlap and tend to counteract each other. It is as if the speed of light needs to try to be a constant. The existence of individual electrons and protons disrupts this goal. The combining of electrons with protons is an approach toward this goal. Also, the movement of one electron away from another electron has the same effect.
I define a positive electrical polarity for matter if the speed of light increases with distance from the particle. The polarity is negative when the speed of light decreases with distance from the particle. The effects we have known as electrical repulsion and electrical attraction are the result of these two opposite polarities causing particles to move in a manner that tends to neutralize changes of the speed of light.
I assume, since the source of a positive acceleration of light attracts the source of a negative acceleration of light, that there is a natural goal or speed which light is directed to achieve. I will further assume this goal or speed to be constant. That is to say, the acceleration source moves in a direction that will accomplish the most diminishing effect upon the acceleration of light.
The proton moves toward the electron and vice versa because opposite accelerations of the speed of light tend to cancel each other out. Particles, which are the source of the imbalance of the speed of light, try to move in directions tending to cancel out the imbalance they cause. There are important limitations on the ability of particles to achieve some balance in the speed of light. I will give two of them here.
One is, the particles do not move toward or away from each other just because of the gradients of their light-fields. They can only react to the intermediaries of light, the photons. The existence of light-fields does not cause any direct action between particles. If it weren't for the existence of photons, particles would have no means for revealing their existence to one another. Particles need photons as the catalysts to enable them to move.
The photons are the catalysts because they carry acceleration with them. The amount of this increment of acceleration will not normally be the precise amount that would allow for a secure balancing of effects to occur. The particles accelerate in response to the history, delivered by photons, of motion of other particles. The timing is late, and the acceleration is not the correct amount needed at that late instant of time. Photons gain their increments of acceleration from the motion of the particles. Acceleration is being passed back and forth.
"Let us start from the 'definition for mass' as a starting point. It is an inverse representation of acceleration. This implies that 'something' acts on the body causing acceleration, and I think you are saying that the 'same thing' causes acceleration of light also."
The acceleration of a object is what implies that something is acting on the object. The acceleration, which its mass represents inversely, of light is what a particle consists of. The particle is the local control of the speed of light. Light is photons. There is no 'thing' that causes both a particle to accelerate and causes light to accelerate. The particle causes light to accelerate and light cause the particle to accelerate. A photon is said to be brought into existence when a charged particle changes its velocity. The photon is very small and is incremental in size and scope. It carries away an increment of the acceleration of the particle that brought it into existence. When the photon later impacts another charged particle, it causes that charged particle to change its velocity by the stored incremental amount.
"Using that, you obtained a new equation for force. The equation suggests that force has no unit; it is just a ratio."
Only the definition of mass as the inverse representation of the acceleration of light is used. Mass has never been defined before this. It has always been recognized to be a fundamentally indefinable property of physics.
When the defined mass is substituted into the force equation, it is learned that force has reduced units of unity, meaning it is unitless. What I mean by reduced units is that the full units of force at the units of one acceleration divided by the units of another acceleration. You are correct that the units do cancel out and force becomes a ratio of unitless numbers. However, that is what it always has been. A force is compared to a unit of force by dividing the force by that unit of force.
If you have the mathematical skills to read the attached paper below then, you will see a very important example of the benefit of recognizing that force is naturally unitless.
"You have expressed charge in seconds; that means charge is made up of time."
It does not mean that charge is made up of time. Nothing is made up of time other than time itself. What it means is that there is no such thing as electric charge. The magnitude of an electron's electric charge is now recognized in my work as a measure of time that is far more important than its past role. In physics equations rates of change are almost exclusively measured with respect to time. This is represented mathematically as (A measure of change of a property)/dt where dt is a near infinitesimally small measure of time. Replace that 'dt' with an incremental measure of time having the magnitude attributed heretofore to the property called 'electric charge' and the equations of physics suddenly become connected together displaying that fundamental unity does exist. This special increment of time is represented in my equations by 'delta t' where delta is the triangular greek letter Delta.
