The fermi paradox:
~There are billions of stars in the galaxy that are similar to the Sun, and many of these stars are billions of years older than the Solar system.
~With high probability, some of these stars have Earth-like planets, and if the Earth is typical, some may have already developed intelligent life.
~Some of these civilizations may have developed interstellar travel, a step the Earth is investigating now.
~Even at the slow pace of currently envisioned interstellar travel, the Milky Way galaxy could be completely traversed in a few million years.
So, is there intelligent life or any life in the universe? Do aliens have communism already, was posadas right?
