Our understanding of the Universe rests on a relatively simple 6 parameter model. The parameters are constrained to percent level precision using the earliest light in the Universe. Nevertheless, the rate of expansion inferred from the model and the rate of expansion we determine in the local Universe no longer agree. Taken at face value, this says the existing model is wrong. I will explain why this is likely to be the case and highlight other observations suggesting that even our understanding of the rate of expansion may be incomplete.


Eoin Ó Colgáin is a mathematical physicist who is interested in anomalies in astronomical data sets.
