The Tale of Enrico Fermi and the Paradox that Never Was.
Seriously guys. The universe is almost definitely awesome, it’s just not adhering to fantasies we made up when we thought traveling to another planet would be just like getting on a boat. The thought process behind Fermi’s Paradox is closer to Creationism than Science.
The default really shouldn’t be ‘OMGZ everybody diez’, right?
