"Crisis in Cosmology - aka, The Hubble Tension"

Tonight's lecture is on one of the most intriguing puzzles in modern cosmology: The Hubble Tension. This phenomenon refers to the discrepancy between the rate of expansion of the universe as measured by different methods. On one hand, we have measurements from the early universe, such as those from the Cosmic Microwave Background (CMB), and on the other, we have measurements from the local universe, such as those using Cepheid variables and Type Ia supernovae. Despite the precision of these methods, they yield different values for the Hubble constant, leading to a tension that challenges our understanding of the cosmos. Today, we will delve into the methods used to measure the Hubble constant, explore the possible reasons for this discrepancy, and discuss the implications for our understanding of the universe.

All programs rain or shine. Time machines will be provided by the Westminster Astronomy Club.
