I’ve had similar thoughts and assume aliens would use something like lasers to have point to point communication rather than broadcast RF.
Of course for us we’d never detect those point to point transmissions unless we were incredibly lucky to be along the vector between two aliens communicating.
- meowface 8y agoEven if you assume a "manycast" or "broadcast" type of communication rather than point-to-point, e.g. some kind of technology which could radiate information-packed gravitational waves traveling at light speed in all directions of 3D space simultaneously, and even if you assume hundreds of thousands of independent intelligent civilizations throughout the universe are doing this right now, it is likely humans will never, ever detect any of them, due to the sheer size of the universe.
