Gamma-ray bursts are the sources of kilonovae, which are among the most interesting of the Big Bada Booms. 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

  • Just came across your channel...binge watching/ listening now for three days straight... thank you... happy new year
  • @digetalised
    Hello Jason .. this is the 8 th time i am watching your lecture and still finding new info. Please keep them coming. You are super awesome
  • Somehow just found your channel. Bravo. Your work is greatly appreciated!
  • @Mrbfgray
    Excellent. Compelling presentation, clear easy to listen too properly done.
  • @bony3603
    ive covered almost all Astronomical channel and none has this much info
  • @ashpool3686
    These are amazing. Great job. I’ll be watching every one.
  • @gwaith6666
    Awesome and super interesting video, thank you Jason! I am so fed up with popular science from Discovery Channel/National Geographic. This here is pure science yumm <3
  • @daveb5041
    Do you have a new set of lectures for 2021-2020 ? You could cover FRB's and other new things that are coming out. Love the detail of this series, never have I seen such detail that was for someone who only took astronomy101 in college and can understand without going to heavy into the math. Nothing against the math I just dont remember most of it from college, so it can make for a very boring lecture when I watch you tube for fun and learning; but not college course take notes with my calculator out style learning, (Although I do that with some chemistry videos but that happens to be my favorite subject. more like the discovery channel for smart people. I out grew the discovery channel when I was 13. Also would like to see a more detailed episode on the CNO and O Si Ne cycles and how they work could make a quick 20 min video to supplement your red giants episodes.
  • @eschdaddy
    Quick question: with the new info on Betelgeuse’s Super Nova coming in decades and that it’s poles are facing our approximate location, what’s the chances of us experiencing one of these?
  • @rescdsk
    92 GeV is enough to have macroscopic effects! It should be enough to raise a grain of sand by a millimeter, per my favorite Wikipedia page, orders of magnitude (energy)
  • @knuckles1006
    Are the Gama Ray energy levels of this burst like this high enough to create Quarks, thus a miniature BIG BANG?
  • @kryten6569
    If I were to be taught by you in school I'll be a genius now ...instead stuck with 3 morons in deep space
  • @deans2beans356
    About 23 minutes in, you state there is 2 potential events per the graph, or 2 types. If gamma ray bursts launch out of 2 sides would it be possible one recording is of one side and another? Like possibly one side puts out more energy.
  • @jamesfox2857
    we were looking down the top of the GRB jet = looking into th Eye of the blast = to far to Directly affect us
  • @disconductorder
    if gamma ray gets redshifted down to microwave, where did the difference in energy go?
