An interesting theory, one that lines up with the fact that the mirror was originally in Canterlot. But if that's the case, how did Sunset know about the existence of the Elements of Harmony? Or, if she already knew about them, how did she know Twilight was the bearer of the Element of Magic?

Besides, Celestia didn't overlook Twilight's warnings. She said she "saw the signs of Nightmare Moon's return".

Another thing to consider: Twilight began her studies under Celestia when she was a filly. Did Sunset and Twilight begin studying under Celestia at around the same time? Did Celestia have two personal students instead of one? I guess this is possible, considering Celestia has an entire school.

The way I see it is, either Sunset stayed in Equestria after abandoning her studies and observed the Elements of Harmony (or specifically, Twilight's Element) from a distance before going to the other world, or there were one or two instances where she returned to Equestria to hear about Twilight's exploits. After all, the only way she'd know what happens when you "bring an Element of Harmony into an alternate world" is if she thoroughly researched them. And it's unlikely the other world would have any information about the Elements.
