“The thing’s hollow—it goes on forever—and—oh my God!—it’s full of stars!”

This was more a story about the universe observing us than it was us observing the universe.
Moonwatcher the caveman, David Bowman the astronaut, the black, rectangular monolith from the unknown and of course, Hal 9000. 2001: A Space Odyssey is one of the Science Fiction greats. There are some slow moments but over all the book had that great quality of taking my mind to unexplored regions delving into the amazing mysteries of the universe. This is one of those novels that succeeds in making me, a human being, feel tinier than a speck of dust on the tip of a needle.

Actual 4.5 rating would be more precise.
