The mirror always looks back… (insert annoying spooky laugh)
But, just to be less of a Halloween spookster. The mirror is placed in a rather exotic location in space, and between the mirror and the Earth is… wait for it… youre going to hate this lol… a naturally occurring closed timelike curve! See, I told you youd hate it lol.
Or youd see 20 years into the future… Let that one bake your noodle for a spell…
No you always see into the past.
Light cannot travel back in time. The reflection you’d see in the mirror is the light that left the Earth 20 years ago.

No that’s not how light works. It’s not 20 years either direction otherwise you could use your bathroom mirror to see into the future
