Question: Is it possible for other life-forms like ourselves to even exist in the entire universe? Let alone in our Galaxy?
Quote: "What and interesting and exciting thought. We may be only one of... so far beyond us as to be, well, just beyond us."
Comment: Bryson began coming up with really interesting points on how far things were. It was very interesting to find out that even if we could travel at the speed of light, the traveler wouldn't make it to Oort Cloud in back in his lifetime. I also found it particularly interesting when he began talking about the Oort cloud and had specific speeds about the comets and how long it would take for it to reach Earth. I'm still a little confused as to how they know that much about something they've never seen. How do they even know that there's an Oort Cloud out there?
