Distance from eye to reflective surface unspecified. Capacity to blink twice in the time taken for light to traverse that distance in the relevant frame of reference is unknown.
The moon is about 1.25 light seconds away from Earth. There are retroreflectors placed on the surface of the moon by NASA, some of which are still functioning.
Given the number of people that stare up at the moon, it seems likely that someone has blinked twice with correct timing to be at the same time as their reflection.
On the other hand, I have blinked with my face only a few cm away from a mirror, so my reflection blinked 0.00000000007 seconds after me, so maybe “at the same time” is doing the heavy lifting here in the sense that there is some minimal period of time between most events we would consider simultaneous.
To the light that is traveling from yuy, to the mirror and back - you did blink in the same instant. ie to the photon not time passes between bouncing off you eyelid and then being received by your retna
Why would I care what a stupid photon thinks? What has electromagnetism ever done for me? Nobody even knows what an electromagnet is!
Yeah, dumb photons
i’d rather have a ton of pho.
Ffffffuuuuuuuu-
Unless you are the photon, then everything might be happening at the same time.
Phew!
