How did you get the temperature differential between the two halves of the planet such that life could survive on both sides and travel between them?
Right, yeah. We've got a couple things going on here that are helping with it. The thing about Darkside is-- And I've had to run this through my physicists, and they're all kind of "Ehhh", so we're still working on the physics-- But the idea is there is a light source over there, but it works like a black light. And so, there's warmth, and there's radiation, and that's why people over there are dark-skinned. They've actually adapted to this radiation, there's a lot of UV and things like that. But there is-- It works like a black light. So for a Daysider going over, it's all-- it feels dark and dim, but it's more twilight-ish than it is completely dark, if that makes sense. And with that and with... jet-streams and stuff we were able to kind of justify it mostly. I mean, it's still going to be colder on the other side and things. But I didn't want it to be like snowing and things like that, all the time over there. And so we kind of had to do some jumping through hoops astrologically to make it work.
