Yup just humbled by the fact shec an lug that thing around everyday! Im still baffled by the concept. Their are a couple explanations...but im not too sure this would make an excellent Youtube discussion though hmm
It makes more sense if you assume that there are different laws of physics in Equestria than the ones in Earth's universe. And apparently Pinkie, Discord and other characters occasionally can change/disregard the laws of physics. I personally like the explanation in "Pinkie Pie meets the Universe" fanfic.
In any case, we have to take into consideration that in the Sonic Rainboom episode, Rarity's wings burned because she got too close to the sun. How can we explain THAT?
Is Sun actually much closer to the planet's surface, like a few kilometres above? Maybe it's angular diameter to distance ratio has some unusual properties? Or maybe the energy received from the sun does not decrease with distance squared, but with some other function of distance?
Also, did the ancient Greeks actually visit Equestria, and that's where the story of Icarus took place, or was it the other way around? Maybe the Greeks stole the "artificial sun" technology from Equestria? And Icarus was one of the victims of the experiments with the imported Sun?
*Sigh*... Of course, it's a bloody fairy tale, so anything goes...
It's just... empiricism is rooted rather well in my psyche. It's always in my habit to try and make sense of any fictional setting. I HATE it when things cannot even be logically explained. Who knows how long I have been trying to explain the Sass Squash, or how magic works in Equestria, for one thing...
