This is for the physics nerds out there. If Hubble telescope can see a past event of a distant planet, can the earth’s past be seen by a Hubble telescope placed in a distant planet? The answer is most likely yes. So my follow up. What if there is a mirror like object on that planet that reflected the light back onto earth? Can Hubble then become a window to our past? And can we essentially manoeuvre Hubble to pick up past events “live”? It’s almost like having a drone above us but feeding us images from the past. Sorry about the long question :(
