Neil DeGrasse Tyson: How much would you pay for the Universe?
Me: $3.25, eBay. (First edition, like-new.)
I’m still punching myself for missing out on that signed copy of Shadows of Forgotten Ancestors, so I bought a few hard cover Sagan books as a consolation. Cosmos, an unsigned first edition of Shadows of Forgotten Ancestors, and a few more that I’m keeping an eye on now.
