If I understand thing correctly, if a righty person carries a box of righty food around the world and back to the same place in a certain way, he will end up a lefty person with a box of lefty food - without the feeling of having changed himself, so the other righties around him will look like lefties to him. I'm not fully with you on the math, so I hope ...

I think you can look for an answer in Ediacaran biota, which, as far as I'm aware, lived exclusively in fluid environment. Just browsing through the list, there were a number of radially symmetric genera, but there is also bilateral and even tri-lobed symmetry. Of course, Ediacaran seas are were shallow, and the fact that there was a bottom to be reached ...

Poly-crystalline crystals care not for your hyperbolic spaces If the difference between Euclidean and hyperbolic spaces on the sub-atomic scale are sufficiently small, it may not matter. Said another way, hyperbolic-isity is a macro property of this physical system instead a property of the quantum realm. The concept is similar to how Newtonian physics ...

Is it possible for a self-replicating cell (that means it has a membrane or some form of protection, it has "string-like instruction molecules" and it has molecules to carry out these instructions at the minimum) to be able to exist and function properly? Yes! Apart from the radically-different-physics cellular automaton examples referenced in other answers,...

I actually only understand 3D geometry, maybe you could use a state in between a normal sphere and an eversed sphere (with maybe some holes), with atmosphere inside and outside ? . . and here is a video of a sphere eversion: https://youtu.be/x7d13SgqUXg?t=497

Maybe something like this? Start out at the Red Dot and go upwards with outward-orientation. (Here you're on the "outer surface".) Cross the Horizon and go downwards with inward-orientation. (Here you're on an "inner surface".) Do a moebian flip. (You're still kind of on an inward surface, only flipped.) Go downwards some more with an outward-orientation. (...

So, first of all, the center of the world would be a large topological worm hole. What is on the other end of this wormhole? A space that is topologically equivalent to [0,1] x S^2 (the Cartesian product of an interval and a sphere). The spheres at 0 and 1 are topological wormholes that lead to some pair of points above the world. If this seems hard to ...

Per this physics stackexchange answer, QCD works pretty much the same in 2D, so hooray! You get stable atomic nuclei! The lower dimensionality, however, means that there is less space (both actual physical "volume" and state space) for nucleons to pack into energy shells, so you have fewer stable nuclei--the periodic table is truncated at the bottom. ...
