Yesterday’s Astronomy Picture of the Day is a masterpiece of subtlety, belying the fascination to be found in one of Saturn’s moons. Enceladus is a small frozen satellite, actually a thick crust of ice over what is believed to be a global ocean atop a rocky core. In other words, a hard […]
For one or two posts a year, I have to touch on the idea of extra-terrestrial life, and this particular facet of the topic I’ve mentioned before, but I’m going into it a bit deeper this time. Given the extremely low likelihood of such an event coming to pass, this post counts as far […]
As a species, we like to occasionally speculate on extra-terrestrial life – what it would be like, how prevalent it is, what we could learn from it, and so on. More than speculate, really, because we’re actively looking for it (or at least some of us are,) and have done some interesting theoretical science […]
I’m the middle of a book that will be reviewed here upon completion (well, not right here, but up above somewhere,) and in the meantime, I keep running across thought-provoking content that I want to expand upon. I haven’t been taking notes, preferring instead to keep moving forward on the book, because it’s been […]
Yeah, I’m still at it – there are links where you can find Part One and Part Two of this extended essay to catch up or keep continuity. Meanwhile, I’ll keep going with the idea, which basically is, what are the chances of us contacting intelligent life elsewhere in the Galaxy? This time, I talk about long-distance life affairs.

This continues a rather long-winded essay on my part. In Part One, I talked about the idea of extra-terrestrial life from the standpoint of cosmology, the planetary conditions that might be needed to produce it. In that post, I went out on a speculative limb, always a dangerous thing from the uneducated. Here, I’m going to compound the error as I talk about the definition of “intelligence.” Please turn your irony meter off before proceeding.

I’m warning you ahead of time, this is going to be long, as evidenced by the “Part One” bit above, but hopefully it’ll be interesting as well. I’ll do my best.
One of the staple topics of all-night bull sessions, and not just in college dorm rooms, is the concept of intelligent life elsewhere in the universe, or to keep it simpler, elsewhere merely in our own Milky Way Galaxy. And you can’t discuss the topic properly without bringing up two “key” factors: Drake’s Equation, and Fermi’s Paradox. Both of them, however, do more to bring up questions than provide any answers. I’ll state right off the bat that this was actually the intention of both, though they typically are used exactly the opposite way. I’ll be brief, though.
