No, I accepted that a photon does stay in motion
Of course if capacity to stay in motion into the future is not forever, then that begs the question how long it can stay in motion. If it does stay in motion forever, then that would imply an infinite potential to do so, no?
Okay. So you seem to be missing the point here.
Instead of me telling you where you're going wrong, let's try the Socratic method instead, because when I tell you why you're wrong it just seems to go in one ear and out the other. So, I will ask you some questions, and you consider them and give me your best answers. We'll go back and forth and we'll see if we can reach agreement after a while. Okay? Here are my first few questions. Please try to answer them as fully and honestly as you can, or this won't work.
1. Can you think of anything that might prevent a photon from staying in motion forever?
2. If you thought of something in question 1, please describe why you think it would prevent the photon from staying in motion forever. Do this for
at least one of the things you thought of.
3. In using the term "infinite potential", are you referring to the physics meaning of "potential", or the lay meaning of "potential"?
4. Please write down a sequence of logical steps that would lead from "an object is in motion forever" to "there is an infinite potential"? Try to write this as a logical syllogism. Example structure:
1. All objects that are in motion forever have ... [property X]
2. [Property X] is a type of potential, as defined by the answer to Q3, above.
3. The particular type of potential represented by [Property X] must be infinite.
4. A photon is an object that can be in motion forever.
5. Therefore, a photon has an infinite potential to stay in motion forever.
5. Now try answering your own question about infinite potentials and photons, quoted above.
Once you have responded to these questions, I will tell you whether I agree with you or take issue with one or more of your answers - possibly by putting further Socratic questions to you. The idea here is that
you come to an answer for yourself, rather than having to just trust me and believe things I'm telling you.
In relation to the term "infinite potential", this was the actual question I posed to the forum:
Question: If a particle in a box never comes to rest, does that imply a potential of infinite energy?
What is so obscure and difficult to understand about that?
Well, we'll see. If this is as easy as you say, you'll have no trouble at all in answering the 5 questions I have put to you, above.
Why do you always have to complicate a simple question? You either know the answer or you don't.
I gave you an answer. You either didn't understand my point or my answer wasn't the one you wanted so you decided essentially to ignore it.
Not all answers in this world are easy answers. Just because I know the answer doesn't necessarily mean I will be able to communicate it to you in a simple way, especially if the question itself is problematic. You might not always be in the best position, initially, to decide whether a question is simple or complicated. Some of the simplest-seeming questions can sometimes turn out to have very complicated answers. A good goal is to try to answer a question in a way that is as simple as it can be, but no simpler than it needs to be.
There is no need to unpack the question and look for hidden variables (Bohm)....

A recurring problem that comes up time and again in conversation with you, Write4U, is that you insist on using words whose meanings you don't actually understand - especially when it comes to technical meanings. Worse, when you don't understand the meaning, you're inclined to just make up your own and expect others to be somehow in tune with you.
