*The current orthodoxy of cosmology rests on unexamined assumptions that have massive implications for our view of the universe. From the size of the universe to its expansion, does the whole programme fail if one of these assumptions turns out to be wrong? *

There is a great paradox haunting cosmology.

The science relies on a theoretical framework that struggles to fit and make sense of the observations we have but is so entrenched that very few cosmologists want to seriously reconsider it.

When faced with discrepancies between theory and observation, cosmologists habitually react by adjusting or adding parameters to fit observations, propose additional hypotheses, or even propose “new physics” and ad hoc solutions that preserve the core assumptions of the existing model.
