I am from humanity's homeworld. [ He cants his head, looking at her curiously. ] Earth, or Terra, is the world where mankind first evolved. At least in my universe.

[ Other planets have evolved in similar ways, so other species aren't so different from them. At least the ones they can communicate with more easily. It makes sense, he thinks, that species who have similar senses, skills and types of communication would be able to reach out to each other more easily. No doubt there are countless species out there that humans would have a much harder time communicating with, let alone establishing any sort of relationship. ]

You have a Dyson sphere? [ Impressive. They're not impossible in theory, he knows that. Then again, if her species is so much farther ahead in terms of technology, it stands to reason that they'd be able to build something like that. ] Where I come from, something like that would be used mainly to better harvest a star's energy output. That's the theory, anyway. I don't think anyone's really thought of it as a way to actively prevent things from coming in.
