A universe that came from nothing

After his success on YouTube, the controversial Lawrence Krauss puts his theory on paper about the origin of the universe and the implications for how it will end. Who would have believed that a video about theoretical physics would cause a sensation on one of the world's most popular websites? Because one of Lawrence Krauss's strengths is bridging the gap between science and popular culture. Emphatic, vigorous, ironic, and insightful, Lawrence Krauss won fans and sparked controversial debates by presenting his vision of the origin of the Universe. His success soared when a video of one of his lectures was posted on YouTube and reached over 1 million views. In *A Universe That Came from Nothing*, the cosmologist summarizes the arguments and evidence from this lecture, delving deeper into the idea that not only can something arise from nothing, but it must always arise from nothing.
