Bailey,

When we were in Albuquerque you asked me what was beyond the edge of the Universe, and I didn't have a very good answer. To be honest, I felt like a baseball player that had practiced and practiced (I've read a lot of books and thought a lot about the same question myself), but suddenly I was standing in the outfield and a high fly ball was headed my way (your question)...and I dropped the ball.





Your question is a really good one and a very hard one to answer because the ideas aren't simple and they aren't easy to understand--even for me.



But I've been thinking about what you asked, and I'm really, really glad you did becuase it made me think hard about the question again too.



Next time we see each other, maybe we can talk about this more, but here's my answer: think about the earth. It's a big ball, and when you look toward the horizon it looks like you can see where the earth stops. But you know from driving and flying that there's no edge. Yo…
