That could only be true in one particular inertial reference frame? Surely, it can't be the case that spacetime is flat along all space-like trajectories, whilst at the same time being curved along time-like trajectories. If so, then the orthogonal time axis that makes the spatial subspace flat could be a candidate for Edgar's mysterious p-time.
