SUMMARY

The forum discussion centers on the physics of Thanos's finger snap while wearing the Infinity Gauntlet in the Marvel Cinematic Universe. It highlights the inconsistency of Stark's garage-made gauntlet successfully snapping fingers, despite lacking magical properties, while questioning Thanos's understanding of geometric population expansion. Sean Carroll, a physics advisor for the films, emphasizes that the internal logic of the movie should be treated as data for analysis, rather than strictly adhering to real-world physics. Ultimately, the conversation critiques the narrative choices surrounding Thanos's powers and their implications for population management.

PREREQUISITES
  • Understanding of basic physics principles, particularly geometric expansion.
  • Familiarity with the Marvel Cinematic Universe and its narrative structure.
  • Knowledge of the role of scientific advisors in film production, specifically Sean Carroll's contributions.
  • Awareness of terminology related to population dynamics, such as "decimate" and "sesquimate."
NEXT STEPS
  • Research "geometric population growth" and its implications in real-world scenarios.
  • Explore the role of scientific advisors in film, focusing on Sean Carroll's work in the MCU.
  • Investigate the concept of "suspension of disbelief" in cinematic storytelling.
  • Study the linguistic origins and meanings of terms like "decimate" and "sesquimate" in both historical and modern contexts.
USEFUL FOR

This discussion is beneficial for film enthusiasts, physicists, and anyone interested in the intersection of science and popular culture, particularly those analyzing narrative logic in superhero films.

Apparently there are problems with him snapping his fingers while wearing a glove
And THAT'S what's wrong w/ the "science" in that movie?

Makes perfect sense. It was later shown that Stark's mundane gauntlet he had made in his garage could hold the stones just as well. So the whole deal with seeking out the master dwarf smith and harnessing the power of a thousand suns (or however the process went) was not as much about making a gauntlet that could hold the stones, but about making one that could snap its fingers. That's what's magical about it.
The real physics conundrum is how did Stark's gauntlet manage to snap its fingers, since there was nothing magical about it (apart from the involvement of a talking animal, a green giant, and the ultimate MacGuyver).

Sean Carroll was a physics advisor for Infinity War & Endgame, and explained in one of his podcasts that when approaching any such piece of cinema, one must treat the film as the data and from that infer possible explanations for the on-screen phenomena. It isn't really relevant whether the in-world physics bears any resemblance to our physics. That's part of the fun!

The gauntlet isn't the problem.

The problem is a smart guy like Thanos is apparently clueless about geometric expansion in populations.

Wow. half? Great, that set the universe back by somewhere between a couple of decades (humans) and a couple of days (bacteria).

Exactly what I thought. But no problem. He could just sesquimate the human race again.

But the real question is, if he's all powerful why doesn't he just create a jillion new planets and teleport the excess population there, with everything set up and ready to go. If only he had used his powers for niceness instead of evil.

Of course the answer is that is all secretly about current events, not about the future at all. shocking!

Doesn't 'sesqui' mean 'one and a half'? Recognizing yes, as in 'sesquipedalian' (literallly, a foot and a half long), the word 'sesquimate' should not mean either reduce to one half or reduce by one half (whether 'decimate' means reduce to one tenth or reduce by one tenth I think is unclear) -- I think that the proper term for either of those meanings would be be 'halve'.

Apparently, not in the Marvel Cinematic Universe!

"Suspend all disbelief, yea who shall enter here," I'm thinking...

I was too lazy to look it up. It should have been "mediumate" or "dimidiumate." But sesquimate sounds cooler so maybe it roolz in Marveland.

Decimate is used to mean reduce by one tenth. That's what they did to punish dishonored legions.
