CosmologyCosmology is the empirical study of the organization, structure and evolution of the Universe
At any given time we always think our Cosmology is correct:
Ancient: Earth is at center of Universe
Current: Dark Matter and Dark Energy
At any given time our Cosmological models are always incompleteSlide3
Models are made from observations and are empirical. This necessarily means that models are limited because the range of accessible observations is limited. Good models make predictions that can be tested. This is the "acid" test of any model and is the root of the
scientific method
. Without this test, models can simply be arbitrary
