The universe was created 14 billion years ago in one very big bang. We know remarkable details about the first few incredible moments in our universe’s history, but the instant of creation remains a mystery. Did time itself begin at that moment? Did space come into being then, too? Have there been other big bangs, or is our universe the only one? Cosmologist Janna Levin unfolds what we know of the origin of the universe and what we don’t—from the origin of time to the end of space.
