Are the humans there also 12:1? [[User:King Pando|King Pando]] ([[User talk:King Pando|talk]]) 15:55, 15 June 2026 (UTC)&lt;br /&gt;
&lt;br /&gt;
: 12:1 means 12x in dimensions. I think the joke is that the miniature art builders are so obsessed with miniatures that 1:12 scale is their&amp;quot;normal&amp;quot;, so 12:1 from their perspective is a normal size from everyone else's perspective.[[Special:Contributions/135.180.173.62|135.180.173.62]] 16:44, 15 June 2026 (UTC)&lt;br /&gt;
&lt;br /&gt;
My understanding of the gag is that the miniature builders are constructing a 1:12 model of the Moon to go with Tethys's &amp;quot;scale model of Earth.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
You mean the '''american''' miniature art model builders. The rest of the world will keep waiting for a 1,274.2 km moon [[Special:Contributions/38.25.26.137|38.25.26.137]] 19:56, 15 June 2026 (UTC)&lt;br /&gt;
&lt;br /&gt;
A possible subjoke is a misunderstanding of scaling. Tethys' radius/diameter is 1/12 that of Earth's, but its surface area is closer to 3/500. In terms of surface area, Jupiter's moon Io is closest to the 1/12 scale. It is also possible that this commenter doesn't understand scaling, though. [[Special:Contributions/1.170.227.28|1.170.227.28]] 02:41, 16 June 2026 (UTC)&lt;br /&gt;
:Scaling refers to lengths, i.e., 1:12 scale means the model has 1/12 length, 1/144 area and 1/1728 volume (assuming all dimensions are scaled equally, especially for Earth models sometimes height is exaggerated: https://en.wikipedia.org/wiki/Geoid#/media/File:Geoid_undulation_10k_scale.jpg). --[[Special:Contributions/134.102.219.31|134.102.219.31]] 09:35, 16 June 2026 (UTC)&lt;br /&gt;
&lt;br /&gt;
I can't see why terraforming (as it's usually understood) or orbital mirrors, etc. would be required. Model builders don't usually build a sky and local microclimate to accompany their models. Certainly a significant amount of topological engineering (which is technically a form of terraforming, but not what is normally meant by the term) would be required to provide a workable substrate to build on, and further modifications may be needed to create an environment where the modelling equipment can work and the model would be protected during/after building, but I don't see any need to recreate the atmosphere, surface conditions, etc. of the Earth.

:But if you don't, then pretty much all my 8.3 billion 1:12th-scale humans, that I just bioengineered from scratch to fit this model, are going to die very nasty deaths!&lt;br /&gt;
:That is, in ways other than any of the very nasty deaths that they maybe were already going to be modelled to die of. I mean, it'll force me to not make the 1:12th human that represents you die in the way that you're going to die (but in 1:12th the time! ...yeah, it's still just a single dimension, though some of the physics involved gets trickier), but instead I'll have to find a way to make you die just like 'your' model-human does (don't worry, I'll still try to make it a surprise, but I can't promise that it won't drag on for longer when it finally happens to you). Or else it'll make a mockery of the whole thing. And I'm sure you don't want that! [[Special:Contributions/81.179.199.253|81.179.199.253]] 14:33, 16 June 2026 (UTC)&lt;br /&gt;
::TBH, creating a 1:!2 scale version of me seems a bit cruel in the first place. I've got bad news, though - Wikipedia tells me that Tethys has a mass about 1% of the moon, so even for 1:12 scale people gravity is going to be pretty borked, and I don't imagine they're going to last long anyway. [[Special:Contributions/82.13.184.33|82.13.184.33]] 14:55, 16 June 2026 (UTC)&lt;br /&gt;
&lt;br /&gt;
Would it be fair to say that there's an extra layer of silliness when we have our own moon at 1/4 scale to earth already? [[Special:Contributions/130.76.187.47|130.76.187.47]] 15:02, 16 June 2026 (UTC)&lt;br /&gt;
&lt;br /&gt;
Hmm, no reference to the &amp;quot;sum of all integers equals -1/12&amp;quot; math, with the seemingly infinite number of ships in the line?  Obviously that &amp;quot;equality&amp;quot; uses &amp;quot;equals&amp;quot; in a somewhat unexpected way, given the divergent series. But that's part of the reference I expected, too.
