Theoretical physicist Dr. Michio Kaku makes his first-ever appearance on the program, talking about multiple dimensions as well as hyperspace. He also mused about how humanity is merely a 'Type 0' civilization and that there are likely beings out in space that would be classified at levels far beyond that, including 'Type 3' civilizations who have figured out how to harness the power of the galaxy.

Additionally, Kaku shared his thoughts on alien abductions, the Face on Mars, and the possibility that humans were seeded on Earth by ETs.
