Theoretical physicist Lawrence M. Krauss joined John B. Wells (email) to discuss the origin of the universe and how it could have arisen from nothing. "We now can see a plausible way in which a universe can come from absolutely nothing without any creator," he said, adding that the aspects of our universe which can be measured are consistent with that conclusion. The word 'nothing' is a scientific term (not a philosophical one) that refers to empty space, or an area with zero total particles, Krauss noted. This space is not actually empty but is instead "a boiling bubbling brew of virtual particlesparticles that fall in and out of existence at a time scale so short that you can't measure them," he explained. Space can pop in and out of existence and is where the dominant energy of the universe resides, Krauss revealed. The very laws governing the universe may have arisen spontaneously as well, and may be completely different in other universes, he added. Krauss spoke about the difference between science and philosophy/religion, pointing out the unique role of science in probing empirical information about the world. While he believes it is presumptuous to say categorically, "There is no God," Krauss admitted there is no physical proof to suggest such a being exists. He further asserted that there is no evidence for intelligent design in biological life and in the universe. The Earth is teaming with diverse life forms of all different kinds, none of them designed, Krauss ...
