Perfect Cosmological Principle
  • The rule that apart from local irregularities, the universe is homogeneous in form over both space and time. This rule is hard to test because it applies only on the largest scale, where clusters of galaxies are mere local disruptions, but has been questioned on the basis of plots of the distribution of all known galaxies. In these, elements of structure like bubble walls can be seen, although their significance is not agreed upon.
