Still, these theories were often shut down after all, first the Unicorns and later Princess Celestia and Princess Luna endorsed the models which placed the earth in the center, and they moved the celestial bodies, yes? So clearly they knew best.īut, eventually, as the methods for observing the universe improved, even Equestria had to admit that the Traditional Model simply did not work. Then, once Sol was revealed, these theories and models got even more popular. While most of these did not feature Sol in the center, as they had no idea it existed, many who studied the movements of Venus, Mars and the stars more closely realised that they did behave as though they orbited the earth. Outside of it, what later became the New Model was starting to form, even long before the Sister’s appearance. When the Princesses took the thrones over Equestria, they unified the different models -as well as provide some insight of their own provided to them by their connection to the sun and moon- into the Traditional Model.īut that was just inside Equestria.

But these varied quite a lot from place to place for example, some featured Venus and Mars while others had no mention of them. The traditional model is based heavily on even older models where the earth is placed in the center of the universe, the sun, moon and stars orbiting it. Intro-During the reign of Princess Celestia and Princess Luna, there have been two main models of the universe in use, colloquially known as the 'Traditional Model' and the 'New Model'.
