Is the Meta Model necessary?

Jim,

An accelerating body does have energy by the very fact of its acceleration.
If the acceleration is constant, such as that of a body with a constant orbital speed, then the energy of the body is constant. Increased acceleration, increased energy; decreased acceleration, decreased energy of the body. The body does not need to "handle" a change in energy because the difference in energy takes the form of a difference in acceleration. There is no such state of a body as that of an 'excess' or 'deficient' energy.

This is just my opinion.

Hi JoeP, The acceleration does change as the Earth moves away of toward the sun. Acceleration at a constant rate must cause something more than just counter balancing angular momentum-don't you think? It seems like a silly thing but it should have an explaination as to why a body can be accelerated with no change in energy. If a body is accelerated at a constant rate it will eventually reach the speed of light but even that is not accurate. You can't say the accelerating body doesn't gain or lose energy without violating basic law-right?

"If a body is accelerated at a constant rate it will eventually reach the speed of light."
"If a body is accelerated at a constant rate its speed will never change."

Both of these statements are accurate. Have a nice day.

Jim,

LINEAR ACCELERATION: Example 1. Constant speed, changing direction.
If the Earth gets closer to, or farther from the Sun, this does not necessarily portend a change in linear acceleration of the Earth. There might be other factors that come into play. The "balance" is of utmost importance. It speaks to the Law of Conservation. The overall energy must be conserved. If acceleration increases, then the energy for THAT particular property increases. And, energy is decreased somewhere amongst the other properties of the body(Earth).

LINEAR ACCELERATION: Example 2. Changing speed, constant direction.
The speed of light is a limit. Acceleration will decrease as v-->c. The reason, as I have stated above, is that energy must be transfered from 1 property to another within the same body. In this case, energy is decreasing for acceleration, but increasing for velocity, and for other properties as well, maybe.

LESSON:
The change in the overall energy of a body does NOT tell us about the change in the DISTRIBUTION of that energy within the body. We do not know, beforehand, about the individual changes in energy that will occur for the various properties. The goal of science is actually to determine the laws that will predict this distribution of energy.

Larry,

Can you tell me if the concept of 'elysium-entrainment' is identical to the concept of 'ether-drag'?
(I am new to all this "alternative" physics. I need to ensure that I have a grasp of the vocabulary that others use.)

Thanks.

<b>[JoeP] "Can you tell me if the concept of 'elysium-entrainment' is identical to the concept of 'ether-drag'?"</b>

As it happens I do have an essay on the topic of entrainment under the assumptions of DRP, but it is advanced material. I am waiting for you to finish reading Tom's book and demonstrate that you have a good grasp of the basics. We will probably need to discuss that material for a while before moving on to things like the physical mechanisms of entrainment and electrostatic force.

<b>[JoeP] "The speed of light is a limit."</b>

This is a theory dependent conclusion. You are probably talking about SR, but there are other theories that also make similar assumptions or reach similar conclusion. There is evidence to support it, but there is also evidence to refute it. Other theories can have other assumptions about this topic.

"The speed of light is not a universal limit" is another theory dependent conclusion (DRP in this case, but there may be others), and the <b>same</b> evidence can be interpreted in other ways under the assumptions of this or other theories.

That's why it is necessary to be careful to say, explicitly, which theory you are talking about in a discussion like this. It tells you and your audience whether or not you really understand what you are talking about.
