Paging Lex Luthor: Astrophysicist Neil deGrasse Tyson knows how to defeat your archenemy Superman.

According to Superman lore, the wavelengths emitted by red stars cause Kryptonians and Daxamites to lose their powers. The wavelengths emitted by yellow stars, on the other hand, are what give Superman his powers.

But all wavelengths of light are created equally, regardless of whether they come from a star or some other source.

"It is just light, so if it's light that gave Superman his powers and it's red light that took them away, then all you need to do is shine a red light on Superman and he'd be a crying mess," Tyson explained. "We would have had him figured out long ago."

Scientists also know how much energy Superman's skin could absorb from a star. The hero would need some extra solar panels to account for his superpowers, Tyson said.
