Hubble Tension and Cosmological Standard Model
In this talk, I briefly review the cosmic Hubble expansion and that various cosmological observations have led to the standard model of cosmology. Mismatches in the values of Hubble parameter from local astrophysical measurements and those inferred within the framework of the standard model of cosmology,
has given rise to the “Hubble tension”. This tension, if real and of cosmological origin, puts the cosmological background of the standard model, the flat Lambda-CDM model, into question. I discuss different viewpoints and approaches to the Hubble tension with the emphasis on my own point of view, some of the proposed resolutions and the prospects from the near future observations.
