I feel like I walked into the wrong lecture hall, found out the topic was WAY more interesting than the class I actually signed up for, and liked it so much that I just can’t leave. I want THIS class to adopt me.

This is awesome. I loved the detailed physics of what is actually happening step by step as a star collapses.

21:15 ... absolutely *_amazing!_*

Yea!

Expertly written & narrated. Very detailed, yet understandable, and superbly illustrated. Top notch- Bravo Jason Kendall!

It's ashame it was taught earlier in primary school. I really had to dig to find this stuff when I was young. Solar Masses where different. Every once in a while National Geographic would do a special on it.

The time scale for these events go from billions of years down to milliseconds. Incredible to contemplate.

Thank you professor 😎, neutrinos getting trapped, amazing.

I love your lectures! Thank you for sharing!

Definetely not recommending this as a go-to-sleep vid. It's too much interesting for the brain to just shut off. Thanks Mr Jason, you got my sub :)

Glad you enjoyed it

I teach GCSE and A-level Astronomy and watch these videos all the time.

Second! Love your work. I've learned so much over the past few years because of you. And the shots at creationism are based.

thanks!

Love your content. Would love some degenerate stellar matter videos. Evolution of accretion into balls of neutrons and how they play a galactic role into the substrate of the galactic environment. What are neutron stars role exactly? How do they contribute?

Nice overview. The sound is a little harsh though, sibilant and echo-y. Suggestion : use a softer warmer microphone, and set your mattress against the wall.

Thanks for the tips!

Yay! Supernovae!

You should read Aftermath by Sheffield. It is a great fictional account of Alpha Centauri do just this. Highly fictionalized but an outstanding read

✋ Mr. Kendall, are we able to tell what generation of Star formation a medium is in ? Nice video !

Sorry, but does that nucleosynthesis diagram state that LEAD is partially made in dying low mass stars? HOW? Why are all the light elements from massive stars and the heavier ones from lower mass stars?

I recall the time of the neutrino capture in Japan was off by several hrs from all the Western nations impacts. It was thought at the time that Japan had mistimed the event somehow. Now I don't believe that was the case. But probably as the gamma ray burst was emitted that further neutrinos were emitted at a different time. This should really be examined in the model calculations. Every time examination should be calculated in the model, which shows to me not every thing has been understood fully.

Gluons might act like little springs and bounce.

FUCK YEAHHHHHH

How does a shock wave travel through a vacuum

A shock wave is a sudden increase in the density of material. However, the material outside an immanently collapsing massive star is an extremely tenuous plasma not a vacuum. See images of Eta Carina for an example.

Great Lecture; I watched Your KZread about Sun's Fusion and Neutrinos, The Solar Neutrino Problem. I'm also a fan of (physically possible, though technical hard) SciFi: Lofstrom LaunchLoop (quasi_continuous ballistic, realistically only possible on the Moon) or Isaak Arthur's "Extending the Sun's Lifespan" (to 75E9yrs, by lifting He, the ash of fusion off from the photosphere (together with other metals) and thus, by diffusion, purifying the hydrogen fuel in the core); kzread.info/dash/bejne/latmkribiJS-c8Y.html albeit this would be a humungous effort and it could "backfire environmentally" in the way of permuting this calm G2_V star into a wildly flaring K or M- type (by changing opacity at the least)!!
