Stewart does a great job of summing up everything I believe to be true, which doesn’t mean it is so, but it sounds and resonates with me. If you haven’t watched any of his lectures, I would suggest that you do because he has a simple way of explaining things so that even the newbie just entering this realm can understand. He explains the Kuiper belt, and interestingly, he claims the sun is not hot. Hmm…never thought about that before, I just assumed it was. Enjoy!
