via xkcd: 65 Years.
The alternate text for the image:
The universe is probably littered with the one-planet graves of cultures which made the sensible economic decision that there’s no good reason to go into space–each discovered, studied, and remembered by the ones who made the irrational decision.
As I’ve said before, we must continue our exploration of space. All of our accomplishments here on earth come to naught if we don’t reach out and expand the grasp of the human race. One day, a few billion years hence, our sun will engulf our terrestrial orb and life will cease. When that day comes, we cannot allow Homo sapiens sapiens to go quietly into that dark night, we must have solidified a beachhead on multiple other worlds. But sadly, it seems we’re stuck in our short-sighted, “rational,” political game. If only we could achieve world peace and learn to work together.
Also, for those with technical inclinations in need of a good chuckle, XKCD always delivers.
