Lawrence Krauss joins Justin Trottier at The Star Spot to discuss nothing, and how a universe can arise from it. Covering Krauss' earlier book "The Physics of Star Trek," the two discuss warp drives, time travel and transporters, and then reflect on the likelihood of a space exploration future anywhere like that of the Star Trek universe. Arguing that not only matter, space and time, but the laws of physics themselves, can all be ultimately explained, Krauss defends his assertion that the ultimate question "Why is there something rather than nothing" properly belongs to the realm of science, responding to critiques from philosophers and some in the religious communities. The conversation also focuses on quantum gravity, the anthropic principle, and what it means about our place in the universe that in the very long run, our universe seems to be heading back in the direction of nothingness.
