Let's talk boundaries

It’s time again for our listener mail round-up, and this week, the theme is borders and boundaries. We learn what it means to define the “end of an era,” explore how close is too close to a black hole, and discuss the power of animal urine. Plus, we hear the story about the time the U.S. and Great Britain almost fought a border war… because of a pig. How do different animals mark their territory? How does surveying work? How close do you have to be to get pulled in by a black hole? How do historians decide how to categorize chunks of time? Featuring Eric Salovich, Naoufal Souitat, Dagomar Degroot, and Christine Wilkinson. SUPPORT Outside/In is made possible with listener support. Click here to become a sustaining member of Outside/In.
