Simon Shack is an amateur astronomer, independent researcher, and author. He is the modern champion of an old idea, last held in Tycho Brahe’s time, that the sun is not at the center of the solar system. At first blush, this sounds preposterous, for we have hundreds of years of data that supports the heliocentric Copernican model. But the more you listen, the more your mind melts, because not only does the data fit… it seems to fit better than the conventional model in multiple cases. We spend the conversation unpacking Simon’s model, figuring out what makes it run, the assumptions that make sense, and the loose threads that still need to be woven in. It is a WILD ride, and a truly great exploration of what it means when the same set of observations can produce a radically different interpretation.
