Hello! You keep mentioning gases in the suns atmosphere. Are they gases or is it all plasma? Thanks!

I somehow woke up to this on my phone this morning It put me in a very good mood, your passion and interest is contagious, thank you.

Homogeneity? Do you really want to assume the universe's gender preference and pronouns? Maybe they/them identifies as chaotic. Serious question: why do radio galaxies play such lousy music? This channel is the best.

Fantastic presentation. Loved it! Looking forward to learning more.

Hey you got on TV? That's awesome :) I have a question for you. Knowing what you know, having a sense of consciousness that understands these elliptical objects wildly whirling around us at terrific speed, while our planet itself revolves and orbits the sun... How do you comprehend your relativity? Do you feel like you are still - or do you have a connection to these motions that gives you a feeling of constant motion?

I love your straight-forward, well-informed approach without gimmicks and cut-ins or extraneous commentary. It really appeals to me as a novice trying to get a handle on astronomy, and I feel like I am learning a great deal from these videos. Thank you so much!

the Henry Daper colour chart for planet spectra you showed you could make out a pattern, eddies almost. then what if we had a coloured light source, for as many different pigments and each pigment a coloured light source, could these beams then focus on a single point? just a curious thought

The best teachers are those who have a genuine passion for the subject, and I haven't seen cosmology so eloquently discussed in such an easy to understand way since Carl Sagan.

don't red dwarfs live trillions of years Jason???

Redshift is also proportional to age. The younger universe was expanding, but has it slowed down?

Excellent lesson. Keep them coming brother!

Vesto Slipher sounds like a bad ass Jedi Knight

I know what’s at the edge!!

You, talking about pasta. Me, getting hungry for some pasta.

Hi. This is an uniroinic, backhanded compliment explaining how pleasant it is to sleep through this lecture.

Great remake. Lemaitre was a badass

I REALLY enjoy getting into the actual formulas and do some maths! Such a pleasure to see it, as opposed to all the "popular" channels that seem to be scared to show any numbers at all

At 28:30 it says there is no energy produced above the core, but what about the photo sphere? I thought there was a type of fusion occurring somewhere around there, somewhere above the surface, where the solar wind is accelerated?

I love these videos from Professor Kendal, I feel like I've unlocked so much from the universe from his lessons!

Makes the presentation really clear. I like how light he makes it.

Gluons might act like little springs and bounce.

The sun voice

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?

This was a great episode, I love these early universe explanations, they always raise other questions in my mind however. I struggle with photons colliding as the Pauli exclusion principle doesn't apply to photons or gluons as they are massless. Hence we have lasers. Though gluballs seem different again. And weak force bosons require energy for creation, do they take it from the photons or from spacetime itself? Thoroughly enjoyed it Mr. Kendall, thank you.

1:41:45 "the sun takes 2 1/4 million years to orbit the milky way" Uh no. The sun only makes it 1% of the way around in that time. You have made an error.

Great ❤❤

What's the mass of a quark? Is it close to the size of an electron?

I've been wanting to write a blues song about neutrinos. "I must be a neutrino baby... cause you don't seem to notice when I pass through"

Big bang nucleosynthesis

The aliens would firehouse whatever they drink out of their nostrils and roll on the floor screaming with laughter, when they learn we call our galaxy “The Milky Way”.

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.

Very good videos, can you put them in series so as it will be easy to follow from the first to ......

Thanks for the history, very interesting by itself.

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

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 :)

i love this lecture so much, i have listened to it more than 10 times and i understand it better and better every time

2:34:00 need this image on a shirt.

Dude.

What about direct urca process?

Why can people see northern lights with naked eye in Belgium these days? Is it the sun itself, or its magnetic field of our planet ?

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

@Jason Kendall Thank you for explaining some things for me, so much to learn more

I just want to protest the megaparsec. I mean well all know the age of universe, and speaking in Mly and Gly just seems more natural. And while the light year is a unit tied to the 🌏, it is in a natural way. The parsec is also tied to the 🌏, it also involves a man made unit, the arcsecond. I guess the only truly natural unit of time is one over the Hubble constant…

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

Hello from within 200Mpc of this broadcast!

Hello professor Kendall, I showed up to the “wrong” lecture hall again. You are seriously making me want to take an astronomy course, even at my age of 49….

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

From the nature of the universe to the birth of nature. Philosophy meets science. Jason, you’re a content machine!
