The life Cycle of a star!

[adaburleigh]

nice

[apriltosey]

helium wow that takes soo much heat and pressure thats a badass star this is soo neat i can watch videos like this all day

[logarajanushan]

well done guys thnx for ur information..........

[34ime]

I like the explanation but did not like the song for this, it would've helped if it was just music (no words) but I enjoyed visuals :) Thanks

[brandkeith28]

i dont know about u guys but this did help me understand a little bit better about stuff being taught in my class in college.. and the song was great!

[TheFlyingEagel]

onzin !

[fanyafrnjeta]

wow i couldnt concentrate on the video cuz of the song :/

[iluvpie85]

what about neutron stars?

[SillyZowieNuttyhoppe]

our sun is a main sequence star, so it will shine for another 5 billion years. then it will eventually, become a white dwarf.

[1RadicalOne]

2:26

A white dwarf? An O-type star? You must be kidding. Such stars are truly massive, and are almost certainly destined for a fate far more explosive.

[cyndie26]

1:38

Wrong!

It's FOUR!

[zero12366]

wat song is this

[DraikonZ3]

idk the song but the artist is Evanesence

[wahkao1990]

"Bring Me To Life" is the song name.

[yossie1995]

from what would it expand if it's a black dwarf it doesn't has nuclear power as outward force it only has gravaty to pul it self in until it can't get more dance super nova's only happen when the star emidentley run out of nuclear power that they colapse so fast that it emidentley becomes a black hole and all the matter won't fit in at once so it get's throne out in the form of an explosian

[yossie1995]

a bleu gigant first fuses hydrogen than helium than oxygen until carbon and a proto star doesn't expands at all and a gigant or hyper or super gigant will turn into a black hole or neutron star it's way to massive to turn into a white dwarf

[snickerr34007]

Evanesence Rocks ~

[SevenElemenT]

When a star is born, It's known as a porn star. LOL

[HerrBlob]

Actually its a sort of radiation that comes out from black holes :p

[armeijamies]

Good song and, muddled facts. Random mixture facts from the four evolutionary paths of stars. (five if you count quark stars)

[lithanor]

why this music? fffs

[uglydollfan]

black dwarfs are accually a theary, the amount of time it takes for a white dwarf to become a black dwarf is longer that the universe has been here

[cainisme]

1:42 Pic looks like breasts

[coolkid28566]

GIve this person a chance, this probly a middle school project, so just give tips not bad comments.

[iwasbornreadyMF]

it doesnt aways become a black hole. It can turn into a neutron star.

[ElfieIsKing]

Black holes are neutron stars :P

[iwasbornreadyMF]

no black holes are infinite gravity. neutron stars also are incredibly dense but black holes are infinite gravity and suck in every thing nothing comes back out. :p

[TheGo0fy]

That is as wrong as it can get. Check your fact, Wikipedia is just a click away...

[abysalhydra]

i was just about to say the same

[ChronicallyConfused]

I believe they're actually called "Brown Dwarfs" not black dwarfs.

[TheAnnoyingAsian]

at 1:17 thats our sun, but in blue :|

[slapleatheru3]

Wow!! Cool!!!

[MapleStoryP]

cool

[neosailorsaturn]

i luv thiz song fan

[Mar1bolo]

i HATE this song. this girl sounds like she's singing with her nose pinched shut. so annoying.

[jannonymous]

ya i hate her voice.

[kattnosipp]

A star of this size won't become a white dwarf. It will explode (type II supernova)

[lollipopbrigade]

missed alittle information but good vid and Plus there is some wrong infromation

you see after the core fuses together it forms silcon after it nuclear fuses silcon it makes iron,iron make less energy than it creates Making a super nova, nova depending on density and size of star In some cases A hyper nova witch only comes from stars 2000 times biger than our sun for instance Vy canis majoris af white darfs neautron stars and black holes are a outcome of all types of nova's not death of white

[coolkid28566]

This is a very good video!

[anty45]

cool video :D

[digital24horas]

ole

[TzBom]

this is not a true life cycle of a blue giant, also known as Hypergiant, star colapses when the presure in the core is so huge, that mater fuses into iron and higher.

[lollipopbrigade]

The core does not go higher on the peroidic table than iron

the reason for this is because it makes less energy than it creates and the blue gaint Is just one of the final stages of a star and Hyper gaints reach an amazing 2000 times bigger than the sun witch is very rare I do not belive they found any stars That may be formed into a hyper gaint any time soon

[TzBom]

The core goes higher then iron for sure, read some phisics man.

Iron requires more energy to fuse than it creates, BUT this doesnt matter, because the presure is still huge enough for the fussion.

If there were no heavier matter than the iron in the cores of supernovas, there wouldnt be any heavier matter than iron in the whole universe

[xoxfinaxox]

my physics teacher told me that elements that are heavier than iron are made in a supernova explosion of a huge star as there is more than enough energy to produce them.

[ChronicallyConfused]

Your physics teacher is correct :) Nothing heavier than iron can be made by the crushing gravity the star generates alone. It is only when it explodes can it continue to make the heavier elements.

[lollipopbrigade]

Sorry to say But after the silcon nucli are fused to make iron it takes for energy than it gives off

resulting in super nova before a second fusion

[TzBom]

so how did all the heavier matter come from? Dumbass...

[lollipopbrigade]

Heavier matter is form from somthing called supernovas forming the havier elements.. dumbass

[amooga7]

very nice!

[HansPersonalYtChanne]

ummmmmmmm, cool? :D

[coolkid28566]

omg! nice vid!
