Whether the universe, as measured by the incredibly powerful instruments and operational procedures of “precision cosmology”, accords with the basic assumption of our scientific worldview- the Copernican cosmological principle- is now established.
“The cosmological principle is not in the sky” is no longer merely an argument of a years-ahead-of-its-time science documentary.
It is a the title of an exhaustive study published on the Cornell University scientific preprint site last month.
For those who have been investigating the remarkable alignments of the CMB with our Earth since The Principle debuted in 2014, there is one fly in the ointment of which we wish to make you aware. It comes from a professional, although not a one in the hard sciences of cosmology or cosmogony, but a radiologist named Pierre Robitaille. He has written several private papers although none in peer-reviewed journals.
