Dear Mozibur,
What a refreshing approach! You did an excellent job emulating Plato while keeping the dialogue interesting and entertaining. I think it is an ingenious idea to clothe some modern concepts related to fundamentality in ancient Greek clothes, and the execution was flawless.
The central idea reminds me strongly of that in Stefan Weckbach's essay, and also a little in Olaf Dreyer's. However, you add an additional contextual commentary, not by stating it outright anywhere but by demonstrating it, in a manner usually associated with the literary arts: our understanding of fundamentality has evidently not sufficiently advanced over the last two and a half millenia that a discussion about it today could not have been conducted by the ancient Greeks. And this raises the obvious question: is that due to the inherent nature of fundamentality, or is it due to our lack of progress in this area?
Outstanding job!
My essay also has a strongly philosophical underpinning: usually we associate the subject of interpretation of a theory with quantum mechanics, but I believe, and try to demonstrate, that actually even something elementary taught in freshman physics, Length contraction (and in the second paper, time dilation) admit of more fundamental interpretations which yield new insights with genuine physics content.
All the best to you, and I hope you write more dialogues!
Armin
