Lecturing is something I do best!

Equestria appears flat but that's an illusion. Equestria is more like a bag with the edges connected. If Ponyville was all there was of Equestria, you could walk past a building on the edge of town and end up passing a house at the opposite end of town and find yourself heading for the town center. So Fluttershy's cottage could end up next to Rarity's Boutique even if they are at the opposite ends of town. It all depends on which path you take, and there are an infinite number of paths. This could make travel across Equestria a gamble, as the time it will take changes, even if you take the train. The slightest shake will change your path. But this is all second nature to us ponies. We're born with a sense as to where to go and how long it will take. It would be very strange if the distance from your house to the bakery was always the same. If that were to happen to me I'd know I was dreaming.

The appearance of the sky over Equestria is dependent on velocity. Einstallion worked out the relation between velocity, mass and energy, but understanding the math behind his theories is a bit of a hard slog. It works out like this: because ponies move quite a bit slower than the speed of light, we don't see the curve of the land, we see a gap, and that gap is the sky. Plus the moon, which is a dollop of Equestria that somehow got pinched off. Pony philosophers are still working on that. It might just be a shiny pebble that got tossed into the air at just the right time and place, thousands of years ago. So anyway, we see a gap, a gap that doesn't exist if you move at the speed of light. A gap peppered with stars and stuff.

It gets weirder.

The sun and the stars are borrowed light, extracted here and there, visible to us as stars only because we aren't traveling at the speed of light. The light can be borrowed because at the speed of light, there is no distance and it takes no time to go nowhere -- it's borrowed and paid back in the same instant. The sun is just a really big loan from the nothingness of space that Princess Celestia pushes up from the edge each morning. She's really good at easing it into a track that crosses the sky. Since the sky is an illusion and the "edge" is a single point, it looks like she is pushing the sun up from the same place each day. Anyway, it's a good thing that the entire sky doesn't belch light -- Equestria would burn to a crisp! Some philosophers speculate that that is happening to Luna's moon, which is why it glows, right through the rock! It's like a failed Equestria, floating right above our heads. *shudder*

But what magic makes the stars in the first place? Many ponies believe that after they die, their magic lives on as a star... or part of the sun. They believe that they don't really die completely. And so it goes for the stars that came together to form the constellations, constellations that are very much alive and that step down from the sky to rest and play. Astronomy is such a fascinating field of study! I must get more books on the subject.
