Certain days and hours can feel damn near eternal, though. In the "making of" video:

By the end of the day we were exhausted. Shattered. Then once we got home and reviewed the footage, that's when we realized, "It's not good enough!" We had to do it again.

We had always planned to go back to film the human timeline, the smaller model. So while we were going back to do that model, we decided, "Why not redo the universe model? Make it better. Make it better and easier, so we just put the lights on the ground." But that required us to hand solder every single one of the lights, so that it would be ready, when we got out there, to just be assembled and placed. That was months of soldering. Just sitting there in the evening, soldering little lights. And I'll be pretty happy if I don't ever have to solder a light, ever again, actually. It was worth it, but it was an absolutely brutal second shoot. [...] You know, seven kilometers, and every ten meters, you have to stop and bend over and put something on the ground. Cause you end up doing, like, 800 squats. You become completely exhausted. We got swarmed by bees...
