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.
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
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
Instructions nuclear, toaster stuck in black hole
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.
It’d actually be cool as fuck if we could make some kind of Paycheck-style time machine that lets you see into the past by simply looking at light reflected off other celestial objects.
It could theoretically work looking backwards, but not forwards as it was used in the film. Of course, it’d have to have insane resolution for it to be like a video of what happened on the planet and not just a dot of light.
time machine that lets you see into the past by simply looking at light
You mean, this ?
lol
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? 🤔
You can also watch light move with a camera.
Wow that’s what the movie was called. It’s been on the back of my mind for years.
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.
SoL
Satellite of Love?

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.
