SETI Live: Do Aliens Speak Physics?

Do Aliens Speak Physics?: And Other Questions about Science and the Nature of Reality (Whiteson & Warner, 2025) is a mind-bending exploration into what it would mean, scientifically and philosophically, for humans to communicate with an extraterrestrial intelligence through the language of physics. Daniel Whiteson, a particle physicist, and Andy Warner tackle deep questions: Are concepts like “number,” “space,” “time,” and “laws of nature” universal, or are they shaped by our biology, culture, and perception? What assumptions do we make that might not translate to a species evolved under utterly different conditions? The book pushes us to examine where physics ends and human perspective begins, to reflect on whether alien minds might think mathematics differently, sense reality differently, or have radically different “basic science.”

Join us on SETI Live as communications specialist Beth Johnson speaks with co-author Daniel Whiteson about the surprising places he found ambiguity, what assumptions underlie science as we know it, and what our notion of physics might reveal - or blind us to - when grappling with alien intelligence.
