You missed the ending where Twilight proves that being a horse and lacking basic cognitive capabilities, she couldn't have proven or disproven anything. Therefore magic exists.
Also the ending where she decides that since she can't find any graviton emitters in pony bodies then gravity must not exist.
Ooh how about an ending where Twilight proves that she doesn't exist and finds herself completely unknown by anyone in all of Equestria, including Princess Celestia!
This is a horrible setting and you should feel bad for thinking of it.
