Here's my theory: when Alicorns reach a certain age, like 20,000 or so years, they have to leave the mortal world and return to their own, which I call the Cosmic Plane. See, there's this big city there, called Alicornia, where all Alicorns exist. Now, normal Alicorns are immortal, but Alicorns who were born as a regular pony and THEN became Alicorns, such as Twilight and Cadance, aren't. They're going to die sooner or later. So, bottom line, when Celestia and Luna get to their 20,000th year, they'll have to return to Alicornia. At least, that's what I hypothesize.
