Lawrence Krauss does not shrink from the task. He is a theoretical physicist at Arizona State University, pondering the major questions of our existence. But he also compares real-universe physics with the kind we see in Star Trek movies.
And he is a visitor to Southern Oregon University, part of the campus theme of "Shapes of Curiosity."
His visit to our studio marks his second visit to The Exchange. In this universe.
