Doubting Thomases are thinking the unthinkable. At https://wattsupwiththat.com/2020/04/10/doubts-about-basic-assumption-for... ... a new study by the universities of Bonn and Harvard question fundamental principles of cosmology. Since Big Bang it is thought the universe has expanded considerably. Until recently it was thought it was increasing in size in all directions - what astronomers call isotropy. Cosmological truths are founded on this assumption, we are told. It is possible that they are all wrong - all the assumptions, the actual bedrock of cosmology. Observations appear to require a reappraisal - although a fierce rearguard reaction is also taking place. Basically, the researchers went on to test isotropy - with an unexpected result. Some areas in space are expanding faster than others. They used data from 800 galaxy clusters, 300 of which were analysed by the authors ... the full paper is at https://arxiv.org/pdf/1605.07178.pdf
