Couldn’t we just be perceiving time backward? I’m no physicist, but AIUI the equations work either way. As a sci-fi–head, sometimes I just like to speculate—“What if the ‘point’ of the universe is the singularity of the big bang?” (Yeah, pun intended.) If we’re in a simulation, maybe it’s the final result of the computation. If we’re in a black hole, maybe it’s in the past of the universe within, but in the future of the one without. All good material for a short story, one of these days…
