The rule could be anything, as funny or as serious as you want. The universe will progress in a similar way that it has up until this point, unless your changed rule prevented it from doing so.

Some examples might be:

  • The invention of currency is not allowed.
  • Iron is slightly less stable.
  • The Ancient Greeks are able to cultivate Silphium, which does not go extinct now.

I'm going to keep this for when I have to explain non-Euclidean spaces during game night.

I always use Chess boards to describe non-Euclidean spaces when I "need" to (aka when I get even a narrow chance to)

[–] Postmortal_Pop@lemmy.world 3 points 2 weeks ago (1 children)

By all means, explain it to me! My best way so far was siting the chase in call of Cthulhu and really it's not a great example.

[–] frank@sopuli.xyz 5 points 2 weeks ago (1 children)

Heck yeah, I'll try my best!

So on a euclidian chess board, moving your king one space left would be 1 space, one space up would be 1 space, and one space diagonally would be √2 spaces (some simple trig gets us there).

Chess however, does not obey the laws of Euclidian geometry nor does its physical representation show us things to scale. A king's move diagonally is the same amount of space as a move side to side, 1 space.

It's silly, because spaces weren't directly supposed to represent distance or anything, but it's funny that it works out this way

This is a problem I've always had with Square grids in D&D and it never occured to me that from character perspective a character is warping space to move slightly further for the same amount of movement.

[–] frank@sopuli.xyz 6 points 2 weeks ago

Also non Euclidian! Hexagons (the bestagons) also tesselate and fix that problem nicely

[–] Snowyday@startrek.website 11 points 2 weeks ago

That was great, thanks

[–] Rhynoplaz@lemmy.world 8 points 3 weeks ago (1 children)

I think this one might end up winning.

It would change the topographical nature of the universe. We would probably have to exist in like the 3.1415th dimension or something to make it work.

[–] MegaUltraChicken@lemmy.world 5 points 3 weeks ago

Fuck it, I'm in. Can't be any worse than regular 3 dimensions.
