Let me ask you something right off the bat. How are you feeling right now in this space. Comfortable.A little cramped perhaps. Uh maybe someone's phone light is burning a hole in your peripheral vision. We've all been there, right.Or maybe you're just feeling a little bit restless for the coffee break, which is coming up right after me. So hang in there with me, okay. Cuz I want one, too.All right. So, so um my fascination with space started when I was just n years old. And no, not the kind with rockets.My ...

[Music] [Applause] So, I'm going to talk to you today about something you've all known of since you've entered into this world. You see it every day. Your parents and their parents and their parents for thousands of generations have known of it, too. and your future generations for thousands of years to come will also relate to it.And yet you likely know or care very little about it. And I'm going to change that. It is of course the moon that I'm talking about.So before I get started, I'll share some contex ...
