In August we performed a live taping of the show from a theater perched on the edge of Manhattan, overlooking the Hudson River, overshadowed by the wide open night sky. Three stories about voids. One about a fish that screams into the night – and the mystery of its counterpart that doesn’t. Another about a group of women who gazed at the night sky and taught us just how vast the universe is, and a third about a man who talk to aliens – and the people who tell him he’s putting human civilization at risk by doing so. Finally, we turn back to Earth with the help of a reading from Samantha Harvey’s hit novel Orbital ( https://zpr.io/RNi4sY2JVKxK ) performed by the artist, actor and podcast host Helga Davis ( https://zpr.io/TKGuzzDFnVjN ). What does it mean to stand on the edge of a void, and what happens when you scream into it, or choose not to?
