Although this doesn't have too much of a connection with our predictive systems discussion, during the interview with Jill Tarter, what I found really surprising was the fact that they constantly protect a specific frequency to study the universe. The region of the radio spectrum that is relatively quiet called the terrestrial microwave window. I've never known about this and I found really surprising that they constantly maintained something such as that to look for possible signals that are too narrow for nature to produce but that they believe those with sufficient technology could reach. Especially since she's continues to talk about how the information on this is basically an "unknown unknown", but that doesn't let it stop them from beginning to create a predictive system of their own!
