miniflea: I remember reading Carl Sagans cosmos at a young age and there was a section on trying to determine if a planet was inhabited by looking at satellite photos, and what resolution would be needed to see evidence of civilization. It blew my mind. I guess I had just assumed you could look at the earth from space and say, yarp, people down there.And how difficult would it be to detect our civilization before we littered space with satellites or before electric lights dotted the globe at night? We haven't been blasting em signals in all directions for very long.
with great power comes great insanity: You can easily tell that there's life on earth because its atmosphere is in chemical disequilibrium.I would think there's a qualitative difference between the atmospheric chemical disequilibrium of a planet with stupid life and a planet with intelligent life. I guess you could measure what proportion of the atmospheric contents could not possibly be the products of metabolism.

bmwericus: perhaps signs of an industrial society but does that mean intelligence?
big pig peaches: All the intelligent life left already. They're coming back for me though. Those guys are always messing around.Guys?
