Here are the links to Hubble sites, white papers and other locations where I found the information contained in this 2022 review. These are also the places where you can go to begin your own research. And don't forget, every video has a document on howfarawayisit.com website containing all the text. Download and translate has needed. In closing, I want to thank Jonathan Onstedt for his excellent editing. And I want to thank everyone for all the great comments and questions posted on my videos. I read them all. Keep them coming. And thanks for watching.
