Sun burning without oxygen, how is that done?
The Sun is basically a fireball, it is burning so many tins of matter an hour. How is the Sun burning what it is burning if there is no air to feed the fire? Is it purely some cemical reaction and if so is it producing oxygen to the the burning can take place?

It is a nuclear reaction. See here.
Yes, nuclear reaction, very interesting.
What people keep forgetting is that roughly 1% of of the sun is in fact oxygen.
The combination of gravity due to its mass and the force and energy put out by the fusion reactions of atoms due to the immense gravity keeps it nice and hot. Until the majority of atoms that are being fused together are iron, then it’s toodles good old solar system, but we still got about 3 or so billion years before anything is going to need to worry about that.
Matter comes in tins now? What’s next? Plastic bottles.
@Whitsoxdude good point, i forgot that state of matter entirely.
So in conclusion @Hypocrisy_Central was wrong about everything but managed not to actually say any of it, through bad grammar and spelling?
@Whitsoxdude – LOVE that song
It’s so true too. The sun doesn’t “burn” persay, it shines because there is fusion going on in the core. This creates all sorts of radiation, including infrared (heat) and radiation that is in the visible spectrum. It keeps doing fusion basically until it runs out of elements to fuse, and then what happens next is based off of the size of the star. Our Sun, for instance, will turn into a red giant, then a planetary nebula, then a white dwarf.
@Zyx – But our Sun would have to be larger to burn this oxygen. Right now it’s only 1%, but there will be a lot more when our Sun dies turning into a white dwarf.
