Episode notes

We're planning to do a search for them, but it remains an open question. I wonder what the physics on a binary planet feels like. It might be trivial. The most critical factor would be how massive is the planet. There may be no escape unless you invent a space elevator or something. But then how do we even build the infrastructure and space to do something like that in the absence of a successful rocket program? And so the more and more we look at our Earth and think about the sorts of problems we're facing, the more you see things about the Earth which make it ideally suited in so many regards.
