Star and Galaxy Formation in the Early Universe

[@BigStank]

Loving this astronomy series. I'm a 26 y/o high school educated military veteran that's starting to consider what I actually want to go to college for. So, thank you, Professor

That's awesome, and thank you for your service! Did you make a decision about college, and if so, what was it?

[@PunmasterSTP]

@@Jay_in_Japan That sounds amazing. Thanks for sharing!

[@alonelywitch4042]

If you still happen to have this account, did you end up going to school for astronomy or something similar?

[@BlazeSLK]

I’m a high school science teacher, and this series is lovely for finding new ways to teach these concepts to my students. Thank you for always sharing new ways for this teacher to continue to be a student.

[@heatherthyme1612]

So happy to have found you, Professor Dave. I'm a senior, tired of all the bad news here on earth. Looking to the stars for a great escape. It's great to live in awe and wonder at the vast and mysterious universe. Thanks for making it more more accessible, and therefore even more awesome.

This is HANDS down the best explanation I've heard and I've almost watched every video on KZbin and have many books. Books by Degrasse, Hawking, R.Dawkin, L.Randall and S.Simon. you've beat out those guys on the best brief description

[@germanire]

You're a cut above, Professor D, in explaining things. You have an economy of words that makes info roll out more quickly than other shows, and therefore is more interesting.

[@marwa.emad1991]

you're amazing, Professor Dave. I love your way of explaining and the pics you upload to your videos. makes it really obvious to us. Thank you

Was searching for a series like this so long! Thanks! Your explanations are fun, while very informative and educational, and most importantly, simple.

can't quite understand the "inner region gets hotter" "the outward pressure prevents further collapse from gravity" part 03:12

Looking forward for more videos. I love learning about the universe and how things been formed. Thank you so much professor.

[@user-ej6kh4bs9g]

this deserves more views...

[@sarahdelein2208]

I gotta appreciate how much time and effort went into the making of each video and the entire series as is. The amount of love and thought you put into this is amazing!!

[@MrMegarag]

These series are amazing, thank you

[@ArthurShedsJackson]

The beauty of science as appose to religion is that science is a never ending learning curve. When we are wrong we correct it with new facts and information. As for religion? It's set in stone where no one can question or disagree with without consequences.

[@needsleep1207]

You are awesome Dave. keep doing your thing spreading knowledge, with very easy explanations. Gonna watch the vid on how stars are awesome and create planets now just cuz i know it will be great.

[@bobfels5343]

Omg you cought me in a binge watch again, guess im going to sleep late then :P, awesome stuff, makes one humble in how much one knows.

[@ashish19]

Love these videos. You should place some numbers with these videos, to specify the sequence of the videos. For instance, this is the second video of the history of the universe. Thanks.

[@mikhilsaju6929]

Professor Dave, When do stars exactly start to move around the galactic center do they wait till a planet forms for like a billion years or they start to move when they are formed immediately

[@ProfessorDaveExplains]

All the matter in the galaxy is always moving around galactic center, all the systems, and all the dust that may one day form a new system.

[@dulcx_24]

I love this series! I’m 13 and am gonna be an astrophysicist so this is helpful 😂

[@quedin9990]

your channel deserve more attention, support and subscriber

[@ungmd21]

You haven't explained how most galaxies are the spiral variety with supermassive black holes at their centers. There has to be an explanation for the formation of these supermassive black holes in the early universe. The fact that we do not see new galaxy formation anywhere seems to suggest this happened in the early universe. They were probably quasars. But how did the quasars form?

[@PunmasterSTP]

Star and galaxy formation? More like "Super great information!" Thanks again so much for making and sharing all of these videos.

2:44 I learned that centrifugal force wasn't actually a thing when studying cicular motion. So what's actually causing the cloud to flatten? Is it the cloud's inertia or something?

[@armanmanookianstudent8684]

I think he meant centripetal force.

[@jasimmathsandphysics]

@@armanmanookianstudent8684 no it's definetly centrifugal because it stretches outwards and flattens

[@armanmanookianstudent8684]

@@jasimmathsandphysics Yeah I looked at it again and that's right. I just came to a conclusion because a bunch of times people have said centrifugal force and meant centripetal force.

What does a god have to do with all this?

Huh....all those pics of galaxies looked like they were grouped together or like they formed as separate galaxies, but then the galaxies look like they form an even bigger ring. At least to my eye

[@thunderspark1536]

As he said here, mass groups together due to gravity, as the original atoms did to form stars. The same occurs in galaxies and the clusters that form from said galaxies

Doesn't the em repulsive force counteract gravity to push the hydrogen nuclei apart. As i u derstand the repulsive force is much stronger than gravity

[@Evolcun]

when something is so dense to the point as to start fusion, the gravitational force is equal to that repulsive force.

[@letosvet1]

Could it be that, in the same way stars are formed from gasses slowly collecting, then going on into gravitational collapse to start rotating as a disc around the centre of gravity - that galaxies in their own way are a "Mega-Star" waiting to be formed, in which normal stars are, to scale, the equivalent of gaseous atoms forming in a cloud - rotating in the disc phase, with the proto-star and starbirth phases simply yet unwitnessed, as the amount of time necessary is just too huge ? So basically it is a mutatis mutandis question (can you roughly and to any avail transpose the scale of "gas of atoms/stars" to = "gas of stars (galaxies)/"megastars" ?) Hope the question makes sense.

[@ProfessorDaveExplains]

Nah, stars are way too far apart.

[@letosvet1]

@@ProfessorDaveExplains :D

[@letosvet1]

@@ProfessorDaveExplains So I have been watching on in the series and in a way, the super massive black holes at the centre of some galaxies, growing larger as they absorb more stars and other black holes, are that massive thing growing out of the "starcloud" ? And we can imagine that after infinite generations of this, the black holes will progressively absorb all that is, including themselves, into one single point again, to perhaps give us another big bang - the universe being on an infinite course of creation and resorption ? Anyway, don't feel that you have answer every step of the way, it's just very thought-provoking and I love the content.

[@ProfessorDaveExplains]

That one is a little harder to answer, it doesn't seem that they have the ability to pull in anything other than what is in their vicinity, and galaxies don't really contract, but they do collide, and stars all eventually die, so I don't really know what it'll all look like in a trillion years.

I got another question: where did the energy which made up the early universe came from, since you cannot create all the energy in the universe rn from literally nothing, or can you?

So thats where the confusion of stars being balls of gas comes from. Made from gases but are really plasma.
