If we ever meet intelligent extraterrestrials, will we even be able to talk about physics? Physicist Daniel Whiteson of UC Irvine and cartoonist Andy Warner join Sarah Al-Ahmed to explore one of science’s strangest and most profound questions: if alien civilizations exist, would their understanding of the Universe look anything like ours?

Their new book, “Do Aliens Speak Physics?”, discusses the nature of knowledge itself, asking whether math and physics are truly universal, or if even our most “objective” truths are shaped by our human perspective. Together, they consider what it would take to communicate with alien intelligence and how humor and illustration can make those big cosmic ideas feel surprisingly down-to-Earth.

Then, stick around for What’s Up with Bruce Betts, as we discuss how difficult it is to explain physics to humans, let alone extraterrestrial life.
