Nominull : there may exist more than one completely accurate description of the universe, i.e accounting for all known, or even possible observations that can be made about this universe. These descriptions may be mutually exclusive. Which is true then ? Which is most likely to be true ? Historically, compare epicycles to heliocentrism. Think about Kolmogorov complexity, and occam's razor.
