Today on the show, ALIENS! I'm joined by particle physicist Daniel Whiteson to discuss whether it would be possible to talk to aliens, the difficulties of alien communication, using real examples of animal communication and sensory differences right here on planet earth. Why do hermit crabs have a death cult? Do dogs think in smells? Are pigeons actually physics geniuses? All this and more as we use real earth biology to discuss how an alien encounter might go down. See omnystudio.com/listener for privacy information.
