Orange: In the shooter hypothesis, a good marksman shoots at a target, creating a hole every ten centimeters. Now suppose the surface of the target is inhabited by intelligent, two-dimensional creatures. Their scientists, after observing the universe, discover a great law: “There exists a hole in the universe every ten centimeters.” They have mistaken the result of the marksman’s momentary whim for an unalterable law of the universe. The farmer hypothesis, on the other hand, has the flavor of a horror story: Every morning on a turkey farm, the farmer comes to feed the turkeys. A scientist turkey, having observed this pattern to hold without change for almost a year, makes the following discovery: “Every morning at eleven, food arrives.” On the morning of Thanksgiving, the scientist announces this law to the other turkeys. But that morning at eleven, food doesn’t arrive; instead, the farmer comes and kills the entire flock.

Orange: A Type I civilization can muster an amount of energy equivalent to the total energy output of the Earth. Based on his estimates, the energy output of the Earth is about 1015 to 1016 watts. A Type II civilization can marshal the energy equivalent to the output of a typical star—1026 watts. A Type III civilization’s communication energy can reach 1036 watts, approximately equal to the energy output of a galaxy.
