    If the ant can only move a single direction in time, it cannot reach all the time corners. Every corner in 3 dimensional space has a twin corner, at the beginning and end of time. Since the ant can only walk forward in time, it will only reach 2 4D corners, where it started, and where it ended.

    I wonder what would have happened if someone had attempted to explain sinusoids to that man. Like, they'd probably be called a dumb evil bastard and some racial and homo/transphobic slurs followed by the sort of logic that only schizophrenics can follow. But still, a chunk of this really is just a man mapping squares on circles

    Unfortunately I don’t think this is true. Every 3D face is the intersection of a 2D plane with the upper and lower bounds of the 3rd dimension. So I think a hypercube “face” would be every 3D “plane” at both the very start time AND the very end time. Meaning the ant would need to immediately accelerate to light speed - so no time would pass - and then (otherwise) normally traverse the faces, wait until the end time, and then repeat the process in reverse (still at light speed).
