The ads appear to be random. Also, since I'm browsing from my phone, I don't have NoScript turned on, because I don't have it on my phone. Usually, I don't see any ads, here (Yay for Firefox!).
Thanks to Google Analytics, it's likely that a lot of these ads are based on search preferences. I have no idea why I have the ads I do, it's terribly bizarre.
I'd take a screenshot, but this phone can't do that. Ugh.
@Caleb: BAH! Your explanations are amazing! At least you have a better handle on the technology and physics than I do. Although, I tend to flesh out social and naturalistic stuff a lot. I guess. Also, you can make up a planet and what its environment is like, and I can probably invent an alien lifeform for it. Hoo~
But ships, military tech, and all that isn't always my strong point. Although I was pleased with how I explained Van's gun earlier.
