    Time is a perfectly valid unit of distance. Just look at light years. On Earth, I mostly use the unit of distance me-minutes

    Interestingly, analysing distance in me-minutes reveals that spacetime is not flat, because a distant location on the train line can be much closer to me than something 5 km away but far away from public transit.
