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.
Also it would take at least 10 years to put a mirror there.
Hey, don’t you bring logic in here!
Only after 20 years. Light will take 10y to make it from earth to the mirror, and 10y to travel back.
No, the light would be reflected as soon as the mirror is set up. If the mirror is set up 10 lightyears away it would take 10 years for you to see it and whatever it reflects. There already is light on the way to the position of the mirror before you set it up.
Oops, that’s right!
it takes way more than 10 years to ship a mirror from Earth to some place 10 ly away from earth.
None of these sound like deal breakers to this great idea

NASA: We’ve been getting a lot of footage of you being cringy in high school.
Meh, amateurs. Being cringy as a kid at times is pretty much inevitable. That’s when you learn your ways.
You can watch me being cringy as an adult for decades.
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
“Aw man… that’s the third goddamned cloth I’ve dropped into this goddamned event horizon this week… and it’s barely just Tuesday.”
Instructions nuclear, toaster stuck in black hole
Redd Foxx was ahead of his time.
and if you look through the butt end of the telescope, you can see in the future
Isn’t the butt end, the end you normally look through? I’d think the end facing the stars would be the front end.
You may need to squint a little.
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.

Sandwich of Lettuce
How long would a sandwich of lettuce stay fresh in space?
Science! and about $70 million dollars oughta do it. Ladies and gentlemen: the intergalactic sandwich bag!
Who wouldn’t love the crisp freshness of frozen solid lettuce?

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.
