In this video I explain astronomical redshift and how we can use it to compare and calculate the distance to a galaxy. I use an acoustic demonstration of the Doppler effect to serve as a model for redshift.
Introduction to Redshift: 0:00
Doppler Effect Demonstration: 3:15
Analyzing our Data: 4:29
Analyzing our Observations: 5:11
Modern History of Redshift: 7:34
Calculating the Z-Value of a Galaxy: 11:04
Using the Hubble Diagram: 14:19
Redshift and the Big Bang: 16:59
