Neutrona Star

I literally just came up with my headcannon and signed up for this site because I needed a place to post it. My theory is that the sun in My Little Pony: Friendship is Magic is not a star. Long ago, before Discord was defeated, he caused such chaos that Equus (fan-name for the MLP: FiM planet that I'm just gonna go with) was thrown from its system. Fortunately, it passed through a hydrogen cloud and the unicorns of the planet managed to gather enough that, with a lot of magical effort, they could ignite fusion. Unfortunately their artificial sun was not nearly large enough to sustain fusion on its own, and so they had to 'raise' its power each day. In my theory, Celestia doesn't actually move the sun. She simply keeps it 'charged'. What happens when she doesn't raise the sun, for whatever reason, is that it actually goes out. My theory doesn't account for what Luna does, but I'm getting ideas now... I have read fanfictions where she has grativational/time-warping powers, so perhaps what she does is ensure that the moon is always directly opposite the sun. After all, if they are relatively the same size and at the same distance from Equus (as opposed to the sun being a star much larger and further away than the moon) then either one of them moving slightly out of sync with the other could cause devastating gravitational effects - this could easily happen if the sun is slightly larger and further out, and thus has a slightly larger orbit. By extension of my original theory, when Luna originally asked for a longer night, she was asking Celestia to let the sun go out. If it were as simple as slowing down the orbit of the sun (or planet, if they had a traditional star system) she probably would have said yes. With my theory though, Celestia wouldn't have been sure she could reignite the artificial star after the long night was over. And since the whole planet was relying on it for heat, light, and life in general, she was forced to say no. This helps to keep Celestia in a sympathetic light, and as I follow the theory that Luna was not in her right mind (due to either outside influence or stress and low self-esteem), I have a guilt-free high opinion of both princesses.
