Some of those were *really* interesting.
Especially the one about the super-earth. Imagine if we found humanoid life on that planet. Now imagine that it was still in the stages of Neanderthal Man. What do you think we'd do? Introduce ourselves and get our own cave paintings of men in rocketships or just leave them be and watch and learn?
Docholly, a link to the source for each of those right by the factoid would've been really helpful and interesting, rather than the clump of them at the bottom of the post. Great list!
