Hi, when discussing the "early universe" where the physics "is not known" it is important to give an idea of when this is, ie < 10^{-14} s after the big bang. Since, this is "early" in a logarithmic sense, but to most people 10^{-14}s is actually a very, very, very small amount of time, so it is clear that some idea of what "early" means in this context, ie, *not* the first hour, or first day, or first week, indeed even the first second, or first microsecond etc are all *not* the early universe in this context, since with have a very good idea of what the physics was this far back.
