Classroom Aid - Dark Energy

Text - Music and ad free version - website - Wiki page In this final segment of our “How far away is it” video book, we cover the structure of the visible Universe as we currently know it. We start with some galaxy and galaxy clusters beyond our local superclusters, including: Abell 2029 with its supermassive galaxy IC 1101; Quasar Markarian; a massive cluster gravitationally lensing a more distant cluster; El Gordo; some distant supernovae remnants; gravitational lensing in giant galaxy clusters like Abell 1689, Abell 68, and more. We then cover dark matter discovery in the Coma cluster and evidence for it in the Bullet cluster. We see a gravitationally lensed supernova; Next, we cover slowly expanding space and the impact that has on measuring distances using GN-z11, currently beyond the visible horizon, as an example. We also cover how
