From a quick Google search, it appears the idea of that universe a three-dimensional torus shape.

Very interesting idea! I think that step 2 could even be optimized a bit, because the "twin universes" have some symetries:
.. I'm curious to see how our simulations will look like in the "wrapped universe".
Great optimisation ideas!
There's an experimental branch with lots of hard coded values. I created a "uniform" spawn script which is just randomly placed particles. I was expecting particles to only be interacting with their local area, but instead they started moving towards the centre. This happened even when I removed any calculations towards the middle universe. This could very well be a bug in my modifications, because to me, it doesn't make sense for this to happen! I found a video of someone else doing similar, with many more neighbours, and the same thing happens: https://www.youtube.com/watch?v=KkgyKQantbg
There is a rendering problem when particles wrap around. The particle tails create a long line from one edge to the other. Not a big deal to solve it though. Either keep a ledger of wraps so gfx knows to skip that render, or detect if the position difference is very similar to the width and skip it.
I'll play with it some more today.
hmmm...
My suggestion has two parts, the first could be an interesting type of simulation, and both parts joined would be the full idea.
This will slow down the simulation by a factor of 6, but might give a very different, interesting simulation. The aim is to make the universe not have a centre point of gravity where all particles tend to go towards, which is more like our current universe.
Initially this could be a variable called
boundary_mode
to be 0 by default and 1 as the first point above, and 2 as the two points above. These would mean "No Wrapping", "Position Wrapping", "Position + Gravity Wrapping".*Not sure how to determine how much more accurate it is.
