Small error in this comic. It's not possible to tile a sphere with just hexagons. AlanKilian (talk) 16:03, 8 March 2019 (UTC)

Six triangles form a hexagon - just an explanation for people with less mathematical or geometric knowledge. --Dgbrt (talk) 16:17, 8 March 2019 (UTC)
but a indefinite large group of triangles doesn't automatically transform to hexagons, since it could be overlapping hexagons, or hexagons with their interim spaces filled up by triangles?--Lupo (talk) 16:29, 8 March 2019 (UTC)
Look at that hexagons (consisting of six triangles), each fitting to the next, and you will understand that this is only possible in a plane but not in a sphere. --Dgbrt (talk) 16:37, 8 March 2019 (UTC)
Yes, but if the triangles are not actually equilateral then they could form a sphere. And if the sphere is big enough (I think solar-system-surrouding or bigger counts) then you probably wouldn't be able to see it with the naked eye. Shamino (talk) 17:08, 8 March 2019 (UTC)
But can it form a basketball? Netherin5 (talk) 17:24, 8 March 2019 (UTC)
Your eyes are making the hexagons up. Some triangles would be left over if you tried to make every group of 6 triangles a hexagon. Triangle arrays like this are commonly used in computer graphics, as they are the closest approximation to a sphere: 17:25, 8 March 2019 (UTC)

Oh man where are the conspiracy nuts from a few weeks ago ;-) Cgrimes85 (talk) 17:03, 8 March 2019 (UTC)

Hey, I think this works like Beetlejuice. Shush. Don’t jinx it. Netherin5 (talk) 17:24, 8 March 2019 (UTC)

Ok, I know most of the discussion is focused on the lattice, but are the ships a reference to something? LOTR maybe? Also there’s nothing about the title text at all, and the (more probable than LOTR) Lovecraft reference, considering the mentions of insanity, cosmic horror, and color. (I believe the book was Cool Air?) Netherin5 (talk) 17:24, 8 March 2019 (UTC)
