Dr. Brian Greene, a professor of mathematics and theoretical physics, is featured in hours 2-5. The conversation encompasses cosmology, EMP weapons, and what may be out there and the best way to make contact. They delve into the "theory of everything" or the "unified field theory" that would connect together all aspects of the physical universe.

The unified field theory has eluded scientists as quantum mechanics, dealing with the smallest particles, has not melded with larger phenomena. Greene proposes that "string theory" (positing elementary particles as vibrating strings) may hold the answer.

In the first hour, Peter Davenport from the National UFO Reporting Center discusses recent dramatic cases and shares interviews with witnesses.
