The entropy of systems

Here is my argument:

to bring it down to its simplest form, the universe contains:
energy, space, and motion.

What produces motion?

It can only be by varying the energy content of matter.
What else can it be?

since energy of a mass is varying constantly, this means it is accelerating. (or: the varying energy state of the atom is what causes its acceleration).

Larry: do you agree with this?

Maybe you will understand with this:

Here is the definition of equilibrium:
a state of balance between opposing forces or actions.(as in a body acted on by forces whose resultant is zero)

Does gravity fall under this definition?

Of course not! It is a force which has absolutely no opposing force.
The solar system is moving in a very definite direction. Do you understand the non-equilibrium force of gravity?

This driving force of change is produced by the varying energy state of the universe.
This varying energy state is moving in one direction only.
Is this making sense or not?

You don't have to agree with the standard definitions and meanings of physical concepts, but you do have to know them to communicate with others.

You have two choices: Learn them; or carefully give your own definitions and descriptions in terms of mutually agreed words/concepts, if you can find any in this last category.

Perhaps you might start with what you mean by "energy". In standard physics, relative motion corresponds to kinetic energy. But that is a mathematical concept, not a physical one. For example, we may be at rest on the Earth, but are spinning at about 0.4 km/s, orbiting at 30 km/s around the Sun, cruising at 25 km/s relative to local stars, speeding at 200 km/s around the Galaxy center, etc. There is nothing physical within us at any scale that corresponds with these various speeds and their corresponding kinetic energies.

So in standard physics, motion induces a mathematically useful non-physical concept we call "energy". But energy has nothing to do with causing motion in the body that has it. And it is just wrong to mix energy with entropy because they are distinctly different properties.

You have homework to do before you can succeed in communicating. More basically, you need to learn about the experiments that led to the standard meanings, so you can identify good reasons for changing them if such reasons exist. -|Tom|-

At what speed do electrons within the atoms within your body spin at?
Is this speed always constant?
What is the kinetic energy of that particular motion?
Does this speed vary with time, heat, pressure?

See, no communication is occurring. Have fun. -|Tom|-

[GD] "&lt;Gravititational force&gt; is a force which has absolutely no opposing force."

Ah Ha!

That explains why I keep falling through my chair when I sit down.
