As Superman and Supergirl soar onto the big screen, accompanied by a misbehaving superdog, this panel explores the science and "schmience" of their powers, their humanity despite extraterrestrial origins, and the reality of science fiction and fantasy elements. How do writers address the mechanics of superspeed, superstrength, space travel, time travel, psychological science, and trying to control that dog? Do they make it up, look up the real science, or find a creative mix somewhere in between? Dr. Travis Langley (Batman and Psychology; Star Wars Psychology) asks a panel of experts how—and if—any of it adds up: Kristi Korzec (Superman & Lois), Sterling Gates (Superman, Supergirl), Jonathan Butler (The Flash), Ray Utarnachitt (Legends of Tomorrow), Chelsea Ballinger (physicist/engineer), Ronald Coleman (scientist/writer), and maybe a surprise alien invader or two.
