Supermassive stars

The life cycle of supermassive stars

[@deepspacemachines]

"This star has an unusually high percentage of Silicon and Oxygen." - "Yeah, it's a rock-star" I'll show myself out...

[@MitchTH]

And supernova's are pop-stars.

+ThisIsNotATest- You two are too PUNNY! 😂😂😂😂😂😂

[@SundanceMLD]

ThisIsNotATest get it?

[@siyacer]

Soon it'll be an all star...

[@theletterwynn]

If supermassive stars are celestial rockstars, they would play heavy metal.

[@23AlexandreJ]

This comment is highly underrated

[@jotarobat]

congratulations, the world is now a bunch of gas in space. but it's getting closer together. and it's getting closer together. and it's getting closer toge- it's a star new shit just got made! some stars burn out and die. bigger stars burn out and die with passion, and make some brand new, way crazier shit. space dust which allows newer, more interesting stars to be made, and then die, and explode into even crazier space dust

I sorta knew about all of these but this is the single, clearest, and most concise way I've ever heard it put. I don't sorta know anymore now I fully understand exactly what's going on. Well done lad.

[@dff1286]

Just found this channel and I am really enjoying your videos. Very informational yet hilarious. well done.

[@danielmcelroy4505]

Same--I love the idea of teaching world building by starting in cosmology; brilliant!

[@dff1286]

it really is. I love putting as much realism into my stories as possible and this is something most authors overlook, what their character's world looks like.

[@wtrmute]

... "Nuetron" degeneracy? J/K. Love your videos. Thanks for sharing!

*MY TEACHER TAUGHT ME THIS WAY (for fun):* _.......on a beach, out of the_ *water* _something seems to_ *float* _out of it, it is black as_ *carbon* _and deploys a sword that glows like_ *neon* _you can hear his characteristic heavy_ *breathing* _as he lands himself onto the_ *sand* _followed by his_ *metallic* _footsteps as he climbs the ramp to board his tie advanced_

[@noaholzer9603]

if i were to shoot a single proton into a neutron star, would it be considered an isotope of hydrogen?

[@jetison333]

+Noa Sama this is a really good question actually.

[@TheCanterlonian]

+Noa Sama you'd need an electron as well to balance the charge.

[@WatzUpzPeepz]

+Noa Sama The video is misleading in that neutron stars are not composed entirely of neutrons, rather a layer within in them which is only about 80% neutrons and they do not behave like atom nuclei.

[@The_RoboDoc]

+WatzUpzPeepz but still do you know what happens?

[@noaholzer9603]

Erik Maki I read up up on it, and he's right. Nothing would really happen, just as littel as when alpha radiation (two neutrons and two protons) hits something oh earth, which happens all the time. i didn't assume something would happen, i just thought it would be fun if a celestial body could fall under the definition for a hydrogen kathion, which obviously isn't the case if that celestial body isn't entirely made up of neutrons... really sad actually, that'd be so funny.

[@Manibe37]

Your videos are awesome! I really like to learn complicated things explained in a simple way, and you really know how to do it! :D

[@Artifexian]

Thanks you, will endeavour to keep the videos coming.

[@cythereanmapping]

​@@Artifexian I found a mistake

[@ysgramornorris2452]

Dat rockstar analogy! x)

[@ehhidontknow]

Okay, this channel is freaking amazing.

[@JoeKawano]

Very nice discussion of supermassive blackholes. I'm loving it!

[@doctorwhat9218]

I’m really loving this channel, very informative yet with just the right amount of humour, even my daughter (8) is learning stuff its done so well. Subscribed.

[@lejink]

I wonder how small a black hole can be.. Maybe there's tiny ones floating around out there.. It would give me a reasonable explanation for why my beer disappears so quickly..

[@zolikoff]

Naturally, a black hole can only form out of a massive star collapsing. Larger black holes can form by much more matter coming into a tight place. But smaller ones cannot form on their own. For instance, crushing Earth into its own black hole (which would be 1-2 cm) would just take enormous energy, way beyond what is available gravitationally. The only way to hypothetically make tiny black holes is artificially. Or, just wait until a stellar black hole shrinks enough in size. But you better be very, very patient for that. Also, there's a small problem of black holes not lasting long when they're small.

[@mopippenger7373]

A small black hole would radiate s lot of energy due to Hawking radiation. It's evaporate rather quickly.

[@sednabold859]

+Dee Jay Small black holes explode violently as the smaller they get the more they emit in a feed back loop resulting in their rapid destruction.

[@rhsmn2334]

so true.....

[@Omakhara]

Nice video keep up the good work. But i think you shouldn´t say that the gravitational pull is what prevents things/particles but much rather the curvature of spacetime which the gravity /singularity is causing. Just some critisism, because i really like the approach of the videos being very mathematical and factual whilst other youtubers often tend to gloss over things with school explanations to appeal to a larger audience.

[@simeonfproductions]

Very descriptive video. Keep doing what you're doing!

[@Artifexian]

Will do. Thanks for watching

[@hawks9nkh]

Much better on the speech speed! Good video.

[@tophat665]

Superb .

[@wj11jam78]

If the neutron star is "the final resting place of the star", does this mean that it doesn't deteriorate, thus meaning the universe will never actually reach true entropy? Or was the final resting place analogy an exaggeration, and they do eventually break down like any other star?

[@tomc.5704]

Yeah, that seems to be the case. The neutron stars will cool in temperature over time, and if they're spinning they will slow down due to energy loss from their magnetic field. Same as with an asteroid launched into deep space. There will be no forces acting on it except gravity. It will slowly cool down, but remain a cluster of matter.

[@ariochiv]

It's an exaggeration. The neutron star will eventially cool and the neutrons in it will eventually decay.

[@flowgangsemaudamartoz7062]

It will turn into a cool Iron Star.

[@landonfun1367]

i love these

[@Schattennebel]

Red Dwarf Stars are the less known Rock-Stars which are around forever and survive every new trend the other more massive Stars invent.

[@brachypelmasmith]

stupid question, in regular matter, what force is keeping protons and electrons away? Positive and negative charges attract, right?

[@maxwellsimon4538]

In quantum mechanics, an electron in an atom is not an object with a set shape and size. In many orbitals, the electron is partially inside the nucleus at all times (like in S shells). The reason why electrons don't fuse with protons all the time is that it takes an immense amount of energy to cause that reaction, so much energy that it only ever happens in the cores of massive stars.

[@darkmelvinperezstarx8978]

Like this serise!!

[@dumpsterstu4474]

love the drawings. great channel.

[@Guest-ok2hc]

your a good at drawing

[@missprizm]

Great video!

[@SandeepSinghMango]

My sister found your channel and I'm inlove with it :D

[@azherkrimson1186]

Fuse Neon into Oxygen ? Oxygen is lighter than Neon, it would be fission ! However, Carbon and Helium can fuse into Oxygen

[@beaclaster]

how's N

[@mesoth5848]

0:52 Neon into oxygen? You sure about that? Oxygen is, like, earlier in the periodic table than neon. How would you FUSE neon into oxygen?

[@fastwebcam]

Yep. He messed this up. He might mean nitrogen (N) which is between carbon and oxygen in the table.

[@TheOfficial2000]

So...Stars are the same as shrek?

[@reggie6522]

love these videos keep it up

[@lilguyfinish]

damn microphones make a difference, sounds like you were 10 years younger in the "evolution of low mass stars" video.

[@theneighbourhoodtimes1568]

Its a Great Video, I like it!

[@nightrous3026]

the reason neutron stars can be so dense, is because neutron have no charge unlike protons and electrons. if electrons and protons in an atom didnt repel other atoms we would have an extreeme density, almost that of a neutron star because the atoms could almost touch each other. the reason i say almost is because electrons have mass too they ARE in fact particles that would slam into another atom and push it far enough away that it wouldnt be as dense... but this being a physical rule IS impossible, because the atoms would fall apart and electrons would be lonely so... life would also be impossible because even if atoms were a thing, the electrons and protons wouldnt have a charge, they wouldnt be able to form molecular bonds...

[@Octal_Covers]

supernova = ♪even crazier space dust!♪

[@lukeh5521]

how does neon fuse into oxygen, a lighter element?

[@Athenas_Realm_System]

An interesting star type which is still hypothetical but has candidates that we know of called a gluon star sits between that of neutron star and blackhole where a neutron star forms but is still unstable due to the mass and then over a couple of centuries overcomes neutron degeneracy but not gluon degeneracy...

[@XxXcaioproXxX]

awesome video mate!

[@rheiagreenland4714]

how about we find 700000000 earths, put superglue on them, and stick them together. Do we get a weird abonmostar?

[@jolez_4869]

I happen to have them in my pocket.

[@SotraEngine4]

tbh This, I think, is why we are early in the whole life in universe thing

[@MrRyanroberson1]

just running through your vids, I have an idea that is way too late, it would've been cool to encode the video# into the intro, in some counting system.

[@wrakatere2907]

I think a teaspoon of a neutral star would weigh less (at least according to In A Nutshell) but great video

[@petersmythe6462]

Keep in mind it isn't actually burning all this fuel because it isn't fully convective.

[@spluff5]

What about stars that are between 2-9 x the mass of the sun? How long do they live and how do they die?

[@cythereanmapping]

Glory days

[@verbulent_flow6229]

Where are your sources?

[@TheAntiSaint]

What about hypergiants ect bettlejuce or Uy secut and Vy canis majoris

[@vlogenericsrants948]

They're massive in terms of size, not mass. UY Scuti's currently got the largest stellar radius at 1708 times the radius of the Sun. If placed at the Center of the Solar System, its surface would extend about two-thirds of the way to Saturn. Currently, R136a1, with over 300x the mass of the sun. However, if placed at the center of the solar system, R136a1 wouldn't even reach the orbit of Mercury.

[@clarkvenus62]

Oh so Psy is the brown dwarf...... Oh

[@sueacademy5978]

You should try to add more jokes like gradeaundera Also, nice vid

[@devon5714]

Ogres are like supermassive stars...

[@johntracy72]

Supernova 2006 GY was actually a hypernova, which is a supernova that's about 300 times more powerful than a normal supernova.

[@joshlauriruth4316]

3:02 That would be a hypernova - not a supernova.

[@galloviking4766]

Basically, we're made out of stars boys!

[@andyhunjan]

around 3:25 bells?

[@ozzyramos4929]

What is the core of a black hole?

[@johannageisel5390]

Nobody knows. Because no information gets out and we haven't united the quantum theory with the general theory of relatitivity. If we could master that, we might get an idea about what is in that core.

[@not_nightshade]

The proto starn is also called a t tauri star

[@gabumonboys]

If there are protons in a neutron star, does that make it a huge atom?

[@teli6350]

there ARE protons on the outer layers of Neutron stars, but because the electrons are flying around and having a good time inside the Neutron star it's kind of not an atom. atoms are held together by strong nuclear force, while neutron stars are held together by gravity. also, if N.S. are atoms, they are some very unstable atoms releasing all that energy from it's nucleus, and the electrons are planets.

[@gabumonboys]

Professorbairos Thanks I didn't know that.

[@teli6350]

no problem.

[@greenbloop3248]

0:59 Then ... What would the Felicia become then?

[@alexandermoon6349]

So Hydrogen and helium fuse into carbon then carbon into neon then neon into oxygen then oxygen into silicon then silicon to iron then iron into everything beyond iron but what about everything lighter than iron that's not hydrogen helium carbon neon oxygen silicon or iron basically how is lithium beryllium boron nitrogen fluorine sodium magnesium aluminium phosphorus sulphur chlorine argon potassium calcium scandium titanium vanadium chromium and manganese made?

[@UriMegaConnor]

a black hole the size of a peanut would decay in about 100 million years

[@dff1286]

+Connor Simon That would be a REALLY small black hole. It would have a mass similar to the Earth.

[@DRGTLSSNDR]

Damn, i would like you to be my teacher .. my professor didn't even know what's the atomic mass of an atom..

[@SundanceMLD]

Alessandro Dragoti me too

[@sorenrohrbach2361]

I'm no super nerd and I prefer Marvel, but if a kryptonian is evolved for a Red Sun and become super beings under a Yellow Sun, does that mean that humans, who are evolved for a Yellow Sun, would gain superman-like powers under a Blue Sun?

[@Nicoder6884]

Maybe. But what if a creature evolved for a red sun, moved to a blue sun?

[@JasonTodd339]

Soren Rohrbach no. Humanity hasn't evolved as far as Kryptonians and Daxamites have evolved in DC.

[@sorenrohrbach2361]

dangit, that woulda been pretty cool. oh well, thanks for the answer

[@mesoth5848]

Considering you'd be blasted by radiation, you'd at least glow in the dark.

[@mladen7641]

Morgan Freeman of the stars XD

[@mladen7641]

it's not because he is not a star, he is much bigger than a star, he is all (what did i just write???)

[@carlosfradinho2006]

what about hyper novas?

[@Artifexian]

...After reading up a little on them, I feel like I want to make a hypernova video :)

[@carlosfradinho2006]

then what about rougue planets with tidal gravitational forces due to their own moons? it could create a prepetual source of energy.

[@Artifexian]

I'd reckon the forces the tore the planet out of its system and caused it to go "rogue" would likely eject any moons the rogue planet may have had.

[@JarvisPatterson01]

Noon you pictured the black hole wrong!!!!!

[@vanivanov9571]

Another example of why gravity doesn't make gas clouds into stars. If it did, EVERY star would be a super massive star, as there's more than enough gas in those clouds to form them.

[@vanivanov9571]

There is no next generation of stars. Enjoy the ones we have while they last.

[@mesoth5848]

And what is it then? Also, considering that most of the universe is hydrogen, this generation is hardly the last. Stars are still born.

[@wondersofdavisfamilythedav9492]

What about the 🌞 sun isn’t it massive

[@AlucardNoir]

150 times the mass of a star? isn't that a hypernova?

[@teli6350]

At least THAT was a Wolf-Rayet star blowing up. we have another one in our neighbourhood, just 7800 LY away, that also almost blew up 6000BC, reaching earth's wiew in the 1840s Eta Carinae A. it'll blow up very soon.

[@phuchong4946]

supermassive stars end with this "supernova" it can be a netruon star or a black hole and then it has some this power netruon star NONE black hole can eat everything like the universe

[@sasscrochguy7507]

why are blue stars the hotest?

[@pingu4238]

No, they are blue because they are the hottest

[@mesoth5848]

Because they mostly release near-UV/UV waves. But considering its brightness, you'd probably see it as white. Blinding white. In fact, that would be the last thing you see.

[@local_catgirl3344]

is it impossibly strange how I knew this at the age of 10?
