by Carl Sagan

A breathtaking journey through space and time, exploring the universe's vastness and humanity's place within it. Based on Sagan's groundbreaking TV series.

Geek’s cut

Reads like a debug session for reality itself — diagrams, equations, and mind-bending thought experiments that make spacetime feel like a system you could, in theory, patch.

Deeper dive

Cosmos takes readers on a guided tour of the universe, from the smallest atoms to the largest galaxies, while exploring the scientific method, the history of astronomy, and humanity's quest to understand our place in the cosmos. Essential reading for anyone curious about existence.
