Theoretical physicist Lawrence M. Krauss enlarges our knowledge of the universe by showing us how it began, what we're still learning about it, and what might happen in the future.

Since our inception, humans have been fascinated by the stars. Today, theoretical physicists look for evidence of how the universe actually works.

Lawrence M. Krauss is a cosmologist and theoretical physicist who believes everyone should be able to understand science.

In A Universe from Nothing: Why There Is Something Rather than Nothing, published in 2012, Kraus explains the origins of the great expanse, what we're learning about it today, and what the end of it all could look like.
