THIS IS URGENT: I need some great books that make me more knowledgable about space and philosophy. The only one I can think about is Pale Blue Dot By Carl Sagen. I just need to read books that make me "enlightened" so to speak. So please If anyone has suggestions that would be the best top notch please let me know. I have also been watching lots of Neil deGrasse Tyson so quite possibly books on Astrophysics as well.
