    But only after 10 years. You couldn’t see anything that wasn’t visible from the viewpoint of the mirror beforehand, as from earth’s point of view the mirror isn’t there yet. And if you’re there anyway… you can just look at Earth with the craft that’s on the position of the mirror already.

    You can already do this with the light bent around black holes, it’s just a bit hard to make out the image… make sure you wipe down your black hole with a damp cloth, you don’t want a smudgey black hole

      Isn’t the butt end, the end you normally look through? I’d think the end facing the stars would be the front end.

    It would be neat to record the mirror as it was going.

    Ignoring physics of moving a mirror near the SoL, having a recording of it would both be cool to watch and would help confirm on a macro level the effects of speed-related dilation.

    If you did this quickly with a warp drive or whatever, you would still need at least ten years to see the results, so you could only see as far back as when you put the mirror up at the most.

      No, you can see 20 years into the past, but only in 10 years. If you managed to will it into existence now, the light that left us 10 years ago would arrive at the mirror now and start heading back. That light would hit earth 10 years from now, so in 2035 we’d be able to see 2015

    Big brother called, you weren’t supposed to leak this hack.

    If only they did work into the future then they could have stopped you from spilling the beans.

    Yeah, but it’d take us strictly longer than N years to place a mirror N light years away form Earth, so kinda useless.

      We just need to point our telescopes towards the phantom zone where Zod and his buddies can reflect the light back.
