Gamma Ray Bursts

This even leads to the most important discovery of the 21st century! Gamma Ray Bursts are a major mystery that arose from the verification of the Nuclear Test Ban Treaty of 1963 and led to major discoveries about where most of the heavy elements of the universe come from. This is part of my complete intro Astronomy class that I taught at Willam Paterson University and CUNY Hunter. Here are some WOOPS items: 1) At about 35:10, the screen blanks out. iMovie didn't like it, and I was too lazy to redo it, as I had to whip these out for a class rather quickly. The movie I am talking about is here:    • Overview Animation of Gamma-ray Burst   Supplement the videos with "OpenStax Astronomy" https://openstax.org/books/astronomy/... 23: The Death of Stars https://openstax.org/books/astronomy/... 24: Black Holes and Curved Spacetime https://en.wikipedia.org/wiki/Gamma-r...
