PBS Space Time has done a couple of episodes on Stationary Action and Noether's Theorem that are approachable by those not yet already exposed to Langrangians:

Sabine Hossenfelder also has a good episode on it:

Have you spent much time on "anything not illegal is allowed" forums?
Try to talk about popular movies are TV shows and you get things like this on such sites [1]. Want to discuss an episode of PBS Space Time such as this one [2]. Don't be surprised if this is the discussion you get [3].
What almost always happens on such forums is that the people there who aren't racists, sexists, antisemites, inane conspiracy theorists etc., leave, and the forum ends up being largely just such people.

>Have you looked at their YouTube channels? Eons and SpaceTime are excellent.
I agree. Eons and Space Time are both excellent. I just hope they both start making new episodes soon.
I'd note that you can get those without YouTube's tracking/advertising by going right to the source[0] of those series.

Space Time is fantastic. Upon watching the entire series (catching up to present time, to be more exact, since new episodes are still being released weekly), I went on a graph traversal spree of related YouTube videos. Another great series I loved was from Fermilabs, with Dr. Don Lincoln.
The geometrical point you refer to is a projection, not an empirical fact. PBS has an excellent YouTube series called Space Time, which describes the Big Bang cosmology in some detail, in several episodes. I'm not exactly sure which ones, but I could track them down if you like. However, I might recommend the entire series; you might be able to refine your speculation somewhat.
For those who haven't seen yet any of the PBS Space Time videos and are interested in physics and cosmology, it is really well done. I recommend checking it out. Each episode is pretty short, entertaining, and jam packed with well explained information.
I'm now hooked on the series, and feel like I am more informed about our latest understanding of physics and the universe.
