We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Simulations like this one are intended to make a certain point (the large-scale structure of the universe) but they aren't very realistic. Traveling through space would not be like walking through a snow storm. As the space traveler (or viewer) passes by a galaxy or cluster of galaxies, such objects would grow enormously in size, filling (or nearly filling) the entire field of view. That's hard to portray on-screen, where the dimensions of the objects that represent galaxies are forced to remain essentially unchanged from the viewer's perspective even as they fly past his location.
