Perhaps extraterrestrials are watching humans on Earth, much as we watch animals in a zoo. How can we get the galactic zookeepers to reveal themselves? If we went to a zoo and suddenly a zebra turned toward us, looked us in the eye, and started pounding out a series of prime numbers with its hoof, that would establish a radically different relationship between us and the zebra, and we would feel compelled to respond. We can do the same with extraterrestrials by transmitting powerful, intentional, information-rich radio signals to nearby stars.
