: Watching trought Arrival's windows show that the marathon isn't spining. You
: would see the stars move. And I assure you it would be very noticable.
: I always forget the formula, but I once calculated the rotational speed of
: the Halo for 1G, and even for it's size it has to spin very fast. Someone
: on it's surface is going way faster than us on Earth. So, the Marathon,
: based on a small celestial body, would have to spin VERY fast.
Suppose the windows are holograms? That would explain away a good portion of the 5D Space in M1 as well, although not on the Sfiera.
