These lectures, by Alan Guth and Lawrence Krauss, explain how cosmologists now understand the natural origin of the universe, and why the universe can come from ‘nothing’ and still amount to nothing.
Guth and Krauss also suggest how science can deal with questions about the universe’s "design". This new understanding of our universe radically changes debates with religion.
