The Big Bang presents the mystery of how the universe began in a way we can all understand. Written by an astrophysicist, the pages describe what we know ― and what we don’t ― in a compelling, accessible way. Moving out into the farthest reaches of space, then back home on Earth again, this is a picture book Carl Sagan would love, introducing the wonder of our pale blue dot to the youngest readers.
