I will review the observations, explain why I think paradigm shift on the Hubble Constant is underway and explain where I expect the scientific community to land in coming years.

ABOUT THE LECTURE:  

Cosmology, the study of origin and evolution of the Universe, became a precision science in the early 2000s, when the scientific community coalesced around the current standard model comprising dark matter and dark energy. Analysis of the Cosmic Microwave Background, the relic radiation from the early Universe, leads to a distinct prediction for the rate of expansion of the Universe, aka the Hubble constant H0. Nevertheless, in recent years local H0 determinations have converged to a different value, thereby casting doubt on how we currently understand the Universe. I will review the observations, explain why I think paradigm shift is underway and explain where I expect the scientific community to land in coming years.
