Right. Then, since the story is probably wrong, drop the story and start your idea from the fact.

Sorry, but it is a typical "just so story." With a little imagination, one can come up with endless stories pointing in any desired direction. Could it happen so? Perhaps, why not. Did it in fact happen? No idea.

I think it is an electron, regardless.

Correct. This is already taken in account in the Friedmann equations.

I agree about the dogs' behavior, with a caveat that they don't have to be puppies to internalize the rules. They do it very quickly as adults when a new human master with different rules takes over. I suspect that humans do the same, when their social environment changes.

Comoving with the on average homogeneous and isotropic space. How do you compare time then with time today?

Exactly!

I think it is supported by facts. Here is a fact of existence, for example: For every number, a prime number exists which is greater than that number.

This is the time of comoving reference frame. Slower than what? Slower than a clock which is situated away from this high density. But the entire universe was this high density. There was or is nothing away from it.

As within any social group, e.g., gangs, fraternities, sororities, meditation classes, etc.

His arms will not remain straight. From the initiation of the move near the shoulders until the hands start moving, at least one second will pass.

It is not my belief. It is my understanding. I find it consistent, but I would change it given reason and evidence to the contrary. We are discussing the mathematical context here.

Maybe... But for now, have a good night.

The only idea I have so far is a good computer animation.

My point is presentation vs imitation. Trampoline is not an analogy, but an actual presentation of a non-Euclidean geometry. But not of a black hole. For one, trampoline presents a non-Euclidean geometry of space, but for GR it is essential that the geometry has to be that of spacetime. BTW, for visual presentation of non-Euclidean geometry I recommend the following book - many examples and good illustrations: Visual Differential Geometry and Forms: A Mathematical Drama in Five Acts: Needham, Tristan: 9780691203706: Amazon.com: Books

Thank you. However, it is significantly different from the topic of our discussion, because they actually presented the processes in question, i.e., oxidation-reduction and electrolysis, rather than demonstrated them with a fake imitation, like a trampoline demonstration of black hole:

I think, time is not an object that has a nature. It is a bookkeeping device we use to organize events.

All sets which have 5 elements in them. One can start with 5 and build all other numbers from it, if one wishes. I think so. It's just 5. What is there to measure? No, one can start building natural numbers from any number. It can be 2. Starting from 1 makes it simpler, that's it. Just exist. Relative to what is irrelevant.

OK.

Of course. This range is quite wide, however. OTOH, I might be biased, of course, and my personal experience is very limited, as I'm not a teacher. But that's why I've asked for evidence, if you had one.

I would think that they were interested in the science of demonstration if they wanted to dig deeper, to know how we know that, why do we think so, where did this come from, etc. I didn't see this.

I disagree with the part I've emphasized.

The distinction I make is between being interested in science and being interested in a cool demonstration.

yes, because and that "something" remains regardless of my mind. The statement, has two parts. The first part refers to a "map maker", and the second part refers to the "territory".

The point I've agreed with, but not the point for which I've asked about evidence. That point, I still doubt about. Anyway, I've asked, if you have evidence, and you could simply say, no, it is my opinion, or something like that.
