Natewlie · #2Because there is no oxygen in space or any gas for that matter.There's nothing to be burnt up that's why it doesn't just explode.As to where it came from see the big bang theory or religion.As for the beginning of THAT no one knows and no one ever will, if we knew it would be boring and meaningless existence.well it is on fire we know that much.
88stumpy88 · #1How does it keep burning ???I know the sun is made of gas but where did that gas come from and what is keeping it there?The only reason for my original post was to provide a response to the quoted questions since there's already an answer for them. Anything I said after that is negligible and should be treated as such since I have no opinion to share on how the sun came to be.
Gas that we know burns very quickly and i want to know y the sun doesn't just burn up in one great bang.
Reider · #9I have no opinion to share on how the sun came to be.Why are you explaining your self?Isn't that obvious from your first post.
tenchan4 · #10http://www.youtube.com/watch?v=Zbgul1NpEA8Right-o my good man! I thought I would have to break out my notes from astronomy class. It's a fusion reaction from hydrogen atoms combining to form helium atoms. The sun is so large and dense that it collapses on itself and creates the heat necessary to achieve fusion. It doesn't keep collapsing on itself because the heat released from the fusion keeps it expanding. It's a balance of the two, you see. What happens when all of the hydrogen is turned into helium? Well it keeps on fusing that fun stuff! I forget what it forms exactly, but depending on the size of the star it can start fusing iron eventually I believe, and after that it makes a jolly old black hole if it is dense enough! Otherwise it sits around as a hot, giant rock.There are just clouds of gases floating about in the great ol' universe that aren't big enough to create the heat necessary to achieve fusion.
The sun is a mass of incandescent gas
A gigantic nuclear furnace
Where Hydrogen is built into Helium
At a temperature of millions of degreesThe sun is hot, the sun is not
A place where we could live
But here on Earth there'd be no life
Without the light it givesWe need its light, we need its heat
The sun light that we seek
The sun light comes from our own sun's
Atomic energyThe sun is a mass of incandescent gas
A gigantic nuclear furnace
Where Hydrogen is built into Helium
At a temperature of millions of degreesThe sun is hot...The sun is so hot that everything on it is a gas
Aluminum, Copper, Iron, and many othersThe sun is large...If the sun were hollow, a million Earth's would fit inside
And yet, it is only a middle size starThe sun is far away...About 93,000,000 miles away
And that's why it looks so smallBut even when it's out of sight
The sun shines night and dayWe need its heat, we need its light
The sun light that we seek
The sun light comes from our own sun's
Atomic energyScientists have found that the sun is a huge atom smashing machine
The heat and light of the sun are caused by nuclear reactions between
Hydrogen, Nitrogen, Carbon, and HeliumThe sun is a mass of incandescent gas
A gigantic nuclear furnace
Where Hydrogen is built into Helium
At a temperature of millions of degrees

calvin_0 · #13the Sun is a giant Nuclear Reactor which use Hydrogen (which consist of 70% of sun's mass) to generate Heat and Helium through Nuclear Fusion, IIRC Nuclear Fusion isnt a combustion so they dont need any Oxygen to keep burning.but where does all of that stuff coming from and where does it all end up?like a human, it needs energy to move and perform other mechanical/non-mechanical things. so we eat. after we eat, we process that food and it becomes waste which we eventually push out and a by product is produced. if we take that same idea and apply it to the sun, it doesn't work.similarly, if we have a nuclear power plant or build a hydrogen bomb, there are by products left behind. additionally, we need the chemicals to make and start these things. but with the sun, where does it get these chemicals from.we know the sun is going in one direction in terms of performing it's job, using fusion. so we know that it isn't going fission, so where is the by product?like when you strike a match, it burns but requires that the flame eats the wood as energy, so where does it get this constant energy from? the way we see the sun is like a human who never goes hungry and can always have the energy to perform his task without ever eating or consuming energy. how is that possible?
ultra · #17what about by products [waste]?heat and helium.......
