Star and Galaxy Formation in the Early Universe

Okay, so at this point in the series we are about 150 million years into the lifetime of the universe. We've got a bunch of hydrogen and helium and not much else. But then gravity takes over, and boom! We've got stars! We've got galaxies! How, you ask? Well you'd better watch this!

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

Loving this astronomy series. I'm a 26 y/o high school educated military veteran that's starting to consider what I actually want to go to college for. So, thank you, Professor

I’m a high school science teacher, and this series is lovely for finding new ways to teach these concepts to my students. Thank you for always sharing new ways for this teacher to continue to be a student.

So happy to have found you, Professor Dave. I'm a senior, tired of all the bad news here on earth. Looking to the stars for a great escape. It's great to live in awe and wonder at the vast and mysterious universe. Thanks for making it more more accessible, and therefore even more awesome.

This is HANDS down the best explanation I've heard and I've almost watched every video on YouTube and have many books. Books by Degrasse, Hawking, R.Dawkin, L.Randall and S.Simon. you've beat out those guys on the best brief description

You're a cut above, Professor D, in explaining things. You have an economy of words that makes info roll out more quickly than other shows, and therefore is more interesting.

The beauty of science as appose to religion is that science is a never ending learning curve. When we are wrong we correct it with new facts and information. As for religion? It's set in stone where no one can question or disagree with without consequences.

Good God I'm 37 years old and your videos are the first time I've found a description of Einstein's theory of relativity that I can UNDERSTAND.
