In a sufficiently large universe, there will be sort of a little bubble where the temperature just happens to be a bit lower or higher. And so it looks that these two claims together imply that there will exist some observers who will measure a value of 2.7 Kelvin and others who willMeasure a value of 3.1. If you add in the methodological principle that we should think most likely our observation is kind of what an average observer, a typical observer, a random observer would do, then you get the probabilistic inference to come through. So yeah, it's possible the temperature is really 3.1 and we were just this very rare observer who saw something very unusual but most likely
