featured in the 2013 documentary The Unbelievers, in which he and Richard Dawkins travel across the globe speaking publicly about the importance of science and reason as opposed to religion and superstition. He has participated in many debates with religious apologists, including William Lane Craig and John Lennox. In his book A Universe from Nothing: Why There is Something Rather than Nothing (2012), Krauss discusses the premise that something cannot come from nothing, which has often been used as an argument for the existence of a prime mover. He has since argued in a debate with John Ellis and Don Cupitt that the laws of physics allow for the Universe to be created from nothing. "What would be the characteristics of a universe that was created from nothing, just with the laws of physics and without any supernatural shenanigans? The characteristics of the universe would be precisely those of the ones we live in." In an interview with The Atlantic, however, he states that he has never claimed that "questions about origins are over". According to Krauss, "I don't ever claim to resolve that infinite regress of why-why-why-why-why; as far as I'm concerned it's turtles all the way down". With the publication of his newest book, The Physics of Climate Change (2021), Krauss is urging the use of science, and not politics, ideology, or emotion, to steer the public debate on how to address climate change. Honors In an interview with Krauss in the Scientific American, science writer Claudia Dreifus called Krauss "one of the few top physicists who is also known as a public intellectual." Krauss is one of very few to have received awards from all three major American physics societies: the American Physical Society, the American Association of Physics Teachers, and the American Institute of Physics. In 2012, he was awarded the National Science Board's Public Service Medal for his contributions to public education in science and engineering in the United States. Relationship with Jeffrey Epstein Krauss helped to organize a 2006 conference on gravity, funded by Jeffrey Epstein. The conference was held on St. Thomas in the U.S. Virgin Islands. Krauss defended Epstein after his 2008 guilty plea of procuring for prostitution a girl below age 18. In 2011, Krauss told an interviewer, "As a scientist I always judge things on empirical evidence and he always has women ages 19 to 23 around him, but I've
