In a world where all mirrors show the past instead of the present, Keiji stands in front of a large mirror and sees Nia walking towards him in the reflection, even though in reality, she is standing still. What would Keiji observe if he continues to stare into the mirror without moving? Provide a very short response.
Keiji would observe Nia continually approaching him in the mirror, replaying the past action of her walking toward him. This happens because the mirror does not reflect the current moment, but rather a past event, and Nia had already walked up to where Keiji is standing. Since Keiji remains staring at the mirror without moving, the reflection doesn't update to a more recent past and continues showing the same moment from the past repeatedly.
