Isotropy of the universe is the idea that the universe is the same in all directions, and is a founding principle of the laws of physics. However, that principle has been called into question by observations of galaxy cluster temperatures and luminosities.

"No matter where we look, the same rules apply everywhere in space: countless calculations of astrophysics are based on this basic principle. A recent study by the Universities of Bonn and Harvard, however, has thrown this principle into question. Should the measured values be confirmed, this would toss many assumptions about the properties of the universe overboard. The results are published in the journal Astronomy & Astrophysics, but are already available online."

    I seriously doubt it. Yes, people may be traveling around - but only a tiny proportion of them, the energy costs per kg are just too high. And the opportunity costs even higher - if it takes you 1000 years to get from A to B, it's very unlikely your knowledge or wealth will be relevant when you arrive at B. You'll be a thousand-year-old relic with little of value to contribute to a society that's had over 30 generations worth of advancements since you left. What would someone from 1000 years ago have to offer modern society? Do you really think bank accounts would just sit around accumulating interest for that long? Or keep track of your balance at all? And how would social stability improve by a few people skipping across history? Stability is based on the people actually living life within society, not those who remove themselves from it for centuries at a time.
