    Real time, tho. That way we can see photographs from before cameras, too. Watch what dinosaurs were doing n stuff.

      Unfortunately light wouldn’t remain collimated over a 33 million light year distance which is what we would need to see dinosaurs

        How about heat? Or some other radiation? 🤔

  Alternatively, and slightly cheaper, put a satellite into orbit and just record everything on the ground it looks at, hang onto recordings for 10 years.

    But that’s boring, doing it with light is way better.

    Also the governments already do that and don’t want to share.

      I get that it seems cooler, but you would be looking at recordings with gathered light either way.

        I can get nostalgia looking at my previous address on Maps because it shows my old Jetta in the driveway :D

      Exactly, you can go on Google Earth right now and view the past.

  Wow that’s what the movie was called. It’s been on the back of my mind for years.
