Christian hoygens was the one who first figured out the rings of saturn correctly. He did not have a very good data from saturn, ecause the telescope was small and there was no concept of planetary rings. And so this is why, again, back to the rumsfeld known unknown and all that business, you know, are there things in the cosmos that we just can't even conceive of to explain whatever the mystery is? The equivalent of saturn's s for galileo? Yes.

In this thought-provoking conversation on life, the universe, and everything, Neil deGrasse Tyson tackles the world’s most important philosophical questions about the universe with wit, wisdom, and cutting-edge science. For science geeks, space and physics nerds, and all who want to understand their place in the universe, this enlightening new book offers a unique take on the mysteries and curiosities of the cosmos, building on rich material from his beloved StarTalk podcast, along with dozens of his most popular tweets on science. Shermer and Tyson discuss: the universe, multiverse, big bang, big rip, dark matter, dark energy, gravity, gravitational waves, origins of morality, hard problem of consciousness, consensus science, the unknown, Fermi’s paradox, extraterrestrials, and artificial intelligence.
