Nov 4, 2025 
Daniel Whiteson, a particle physicist and science communicator at UC Irvine, dives deep into whether aliens would understand our physics. He discusses the challenges of decoding symbols across cultures, illustrated by testing the interpretation of the Pioneer plaque. The conversation explores if math is discovered or invented and how alien biology might influence their concepts of mathematics. They ponder if advanced technology necessarily implies a scientific method and whether alien art could reveal shared emotional frameworks among different species.

Episode notes
Questioning Physics' Universality
- Daniel Whiteson questions the assumption that alien and human physics will map onto one another and urges skeptical analysis.
- He argues physicists often assume universality while linguists and anthropologists rightly doubt symbolic translation across cultures.
Pioneer Plaque Test
- Whiteson showed the Pioneer plaque's hydrogen depiction to grad students and none decoded it in two hours.
- He uses this to illustrate how even simple cultural symbols can be inscrutable outside their context.
Is Math Discovered Or Invented?
- The book probes whether mathematics and physics are discovered or invented and how that affects cross-species understanding.
- Whiteson highlights philosophical doubts about whether math is necessary or a human-developed toolkit.
