Nah, this wouldn't work. After all, the Sonic Rainboom episode definitely proved that Equestria's sun is a relatively small ball of fire, MUCH smaller than the planet itself.If Equestria's sun was really a huge star, it would be impossible for Rarity to fly so close to the sun that her wings would burn, let alone cast colorful lights in a wide CONE.If the sun was a distant star, it would cast almost perfectly PARALLEL light rays, yet we see her wings are casting a cone of light, and geometrically, the sun would be at the apex of that cone... which in that scene would be at most a dozen meters away from Rarity. The fact that at that distance she's not obliterated by the sun, but just heated enough to burn the wings and cause a little sweat, suggests that the sun isn't extremely hot like a real star. The sun's diameter can also be estimated here, although the results seem somewhat inconsistent.Either way, the conclusions are:- MAGIC- FRIENDSHIP- ...- Good story, Pinkie.
