Privacy – Solution to the Fermi Paradox?

In an interesting video I recently watched about quantum noise and mathematics, a mathematician jovially commented in passing that maybe the reason we don’t notice information transmissions from other advanced civilizations is because their communications are encrypted.  He said it as a playful joke, but I don’t think he realized how profound this was.  What would encrypted radio (or light) transmissions look like in that case?  They would look precisely random. Exactly like background radiation.

WOW. This is far more profound than (I believe) this mathematician realized. After some more thought, I believe this is the solution to the Fermi Paradox.  (The Fermi Paradox questions why we cannot see intelligent radio transmissions Continue reading
