Black Holes, Gravitational Waves and Gamma-Ray Bursts: Cosmic Catastrophes
This is the eleventh lecture series of my complete online introductory undergraduate college course. This video series was used at William Paterson University and CUNY Hunter in online classes as well as to supplement in-person course material. Notes and links are present in the videos at the start of each lecture.
Black Holes are the ultimate triumph of gravity over matter. The most mysterious objects in the cosmos, as they do not reveal their innards to any probe. Black holes fascinate people who just start learning about astronomy. This is my overview of the premiere Gee-Whiz-Bang-Pow of outreach. 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. Without exception, Gravitational Wave discoveries are one of the most important developments in all of science. Predicted by Einstein in 1911, they were finally observed in 2016. In August of 2017, their counterparts in visible light were finally seen with telescopes.

The guy who said measuring gravitational waves would be impossible to measure and then measured them is a hero of the scientific mindset. Not only was he willing to be proven wrong, he went to extreme lengths to prove himself wrong. Absolutely amazing.
To all involved with this video from the narrator and writers and the artists and videographer and all the scientist , fantastic job well done making a the subject matter easy to comprehend and enjoyable. The voice of the narrator keeping me interested. Surely this won awards and deservedly so.
You've just painted, from scratch, an intuitive image in my head of our galaxy's path through the universe and its relationship to other celestial objects in under half hour.
So easy to listen to. Love the way you communicate the cosmos.
So the idea that an object could have enough mass and gravity that it's escape velocity would exceed the speed of light preventing light particles from escaping dates to the 1700s.
i fall asleep with autoplay on and these videos incorporate into my dreams. From kite surfing to a visit to learning a simple derivation to the event horizon with an argument with the author of the text book on wormhole coupling. To winning a trip to the ISS to dealing with a missing tile on the reentry vehicle and i'm like why don't they invent a ceramic foam like a great stuff bottle for dealing with this and returned to earth to tell everybody what a week a had.
Love all your collections of lectures
Thank You for referring us such an interesting subject!! Amazing is space and matter.
Best universe video for learning, everything explained clearly. 👍
Two words: infectious excitement
Greetings from Sweden!
I don't know why the algorithm has it showed me any of your new posts. But I've been a fan for a long time man
Can you do a video on baryonic acoustic oscillations?
Good stuff man
So just wondering, on another documentary I heard GRB's being referred to as the most powerful particle accelerators in the universe, if that's the case can heavier than than Iron elements be produced by the jets through a super collider process, or is super collision effectively how these elements are produced in a normal Type II supernova?
Thank you for sharing! Gravitational waves and gamma ray bursts are some of the things I love learning about in astronomy
Thanks for uploading this. Really good listen

Jack's only problem was his method of locomotion. Instead of a box, he had gone out on a surfboard there would have been no issues.
What is the size of the gravitational waves at their creation? Are wave size proportional to the mass of the black holes or neutron stars?
