most galaxies visible in the above video are seen when the universe was only a fraction of its current age, were still forming, and have unusual shapes when compared to modern galaxies. No mature looking spiral galaxies such as our Milky Way or the Andromeda galaxy yet exist.
A half-informed lay opinion: take it for what it's worth, which is nothing. If the most distant object reached in this simulation is the most distant object detected in the Hubble Ultra Deep Field imaging project (and I don't know that it is), then it's something like 13 billion light years away. Presumably it is because it's black beyond it, which at a guess indicates that we're looking back toward the birth of the universe and there's no light of that age traveling toward us from that direction. Anyway, that would mean we traveled 13 billion light years in 1 minute. So, like, 7 quadrillion times the speed of light or thereabouts.
