I'd add Conjectures and Refutations (Karl Popper) The Fabric of Reality (David Deutsch) Also Feynman has some shorter/easier but serious physics books that some might prefer: QED and The Character of Physical Law. And his computation lectures book is good.

…rl Popper (of falsifiability fame) once compared spacetime to Parmenides' block universe and called it "Eintein's block universe in which nothing ever happens". (Source: Conjectures and Refutations). In his textbook, "Relativity From A to B", renown relativity expert Robert Geroch wrote, "There is no dynamics within space-time itself: nothing ever moves therein; nothing happens; nothing changes." Very few physicists know this but it's the truth, a nasty little truth for some, but the truth nonetheless. In conclusion, any talk of time travel in any direction (forward or backward) is pure crackpottery. There is only the NOW, the ever changing present. Don't mod me down because you have a different opinion. Incessant propaganda and sci-fi movies like Star-Trek have duped a lot of people. Just think about it and figure it out on your own. Not…
