@GabrielDuquette It would be a lot clearer in terms of Lineland (1+1 dimensional spacetime) but, whiteboard.
@admittedlyhuman @GabrielDuquette 1 space + 1 time dimension gives you 2-dimensional spacetime. Like a globe with 'time' pointing south.

@St_Rev@GabrielDuquette ok I had thought that a 4-sphere was only 1 more than a regular sphere, somehow I have gotten confused -
@admittedlyhuman@GabrielDuquette An n-sphere (or generally n-manifold) is one where a tiny piece of it looks like regular Euclidean n-space -
@St_Rev@GabrielDuquette so why aren't we on a 3-sphere then? -
@admittedlyhuman@GabrielDuquette Go back to the 1+1 sphere where time points south. Fixing a single moment in time defines a circle. -
@St_Rev@GabrielDuquette I thought all the moments in time were the circle and time was pointing different directions at different times -
@admittedlyhuman@GabrielDuquette There are a lot of different potential timefields. But the one I had in mind was...
