Subir Sarkar, Emeritus Professor at the Rudolf Peierls Centre for Theoretical Physics, University of Oxford, offers arguments against the Standard Model in cosmology:
Cosmological data are now routinely corrected by a special-relativity boost transforming the measured redshift and magnitudes of distant objects to the presumptively isotropic cosmic rest frame. In the cosmic microwave background frame, the large-scale averaged distribution of matter is also assumed to be isotropic. The Friedmann–Lemaître equations can then be applied to the transformed magnitudes and red shifts…
These assumptions are no longer tenable. Several independent data sets now argue against the existence of a cosmic rest frame. At low redshift (z ≲ 0.1), all matter in our local supercluster of galaxies has a coherent bulk flow approximately aligned with the direction of the cosmic microwave background dipole: no convergence to the cosmic rest frame is seen on scales as large as ~300/h Mpc. At high redshift (z > 1), the observed dipole in the sky-distribution of distant radio sources and quasars is significantly larger than expected according to the kinematic interpretation of the cosmic microwave background dipole. Phenomena are in conflict with the cosmological principle. They directly challenge the claim that the universe is dominated by vacuum energy, which rests on its assumed large-scale homogeneity and isotropy. These are potentially paradigm-changing developments.
