Natural-Born Scientists - Dr. deGrasse Tyson believes that children, in their own way, are natural scientists. "Almost everything we do to a child limits their creativity. And so, a parent doesn't have to nurture the scientist in the child—they just have to get out of the way," he says. (Photo: Darnell Williams/BET)

Creative Knowledge - Dr. deGrasse Tyson believes that if kids saw what they could do with scientific knowledge they would be more inclined to pursue it. "There are so many other things you can be to bring creative knowledge to understand the world in. Without that we might as well move back into the cave because it's those discoveries that enable us to harness the power of the Earth that would otherwise be killing us," he says. (Photo: Darnell Williams/BET)

Who Built the Pyramids? - Tsoukalos discussed the possibility of the pyramids being built by aliens with Mo'Nique. "I have never suggested such nonsense—of course the pyramids were built by our human ancestors. There is no question about that. However, the ancient Egyptian texts are very clear in stating that they were able to build the pyramids with the assistance of the guardians of the sky or the watchers from heaven," he explained. (Photo: Darnell Williams/BET)
