Cosmic Jackpot, also published under the title The Goldilocks Enigma: Why is the Universe Just Right for Life?,[1] is a 2007 non-fiction book by physicist and cosmologist Paul Davies, describing the idea of a fine-tuned universe.

In Cosmic Jackpot, Davies argues that certain universal fundamental physical constants are precisely adjusted to make life in the Universe possible: that we have, in a sense, won a "cosmic jackpot," and that conditions are "just right" for life, as in The Story of the Three Bears.

As Davies writes elsewhere, "There is now broad agreement among physicists and cosmologists that the universe is in several respects 'fine-tuned' for life.

Davies also discusses a number of other ideas connected with the "multiverse."

Much like a pencil falling to the ground from its tip in a trade off of symmetry for stability, Davies writes that the Big Bang could have established a complex but stable universe (or multiverse) from symmetry breaking as the heat radiation in "space" lowered abruptly past the Curie Point.
