"The Sun And How It EXISTS :D (I worked it out in chemistry)"

Anyway like the title says I worked out how our Sun exists. Everyone knows that the sun is just a star (well a really big star but anyway) and like every star it is basically composed of burning gas wanting to blow it up but like every star it has a gravitational field wanting to crush it into a ball. So since there is this perfert balance between the two forces one wanting to expand out the other wanting to crush it in there star stays in being. Of course the gas still burns away but it happens so slowly the gravity has time to adjust stopping it going super nova. However if we were to take a lump of gas out of the sun suddenly then the gravity would have no time to adjust causing a chin reaction that ultimatley leads to the sun exploding and everyones death. All stars go super nova eventually and although the sun is so big it will be lethal when it does it still has a lot of time left before it blows. So unless they develope a extremely strong material with an extremely high melting point that can survive such an explosion however we are safe until it happens by natural causes...Anyway this was another random yet insightful topic by Cubist hope you enjoyed :D

so the sun can make you go blind in both cases then
hur hur

If The Sun were not here our internet team would need even more cleavages on their iMac desktop pictures.

if the sun was not here we would not be alive.

err, evil things.
had my physics mock on teusday. we were meant to get 3 more weeks of revision time but ofsted are coming in then so we've be pushed into the sports hall for a week of lovly exams.

damn ofsted *mutters under breath*

Even when it does burn out we will have to wait a LONNNNNGGG time before it finally wastes all it's light. It would be cooler if the sun was a supergiant star then uddenl just exploded in a huge supernova. It would release more energy that it ever had in all it's years of existance and blow us dead. That would be Soooooooo cool......oh yea, I mean bad...:|

but the sun is a tiny star compared to all the others in the universe, and so it will become a white dwarf when it eventually dies, but by that time no-one will be able to see it, unless we colonise some other planet

Bah, the Sun is just a fairytale. It is an illusion created by spacemonkeys who want to blind us from the truth.

Don't believe the lies they teach you at school.

Compared to a giant and supergiant star the sun is a pebble. The sun is only a main sequence star at the moment.

I like doing Astro-physics as it is interesting and fun to learn about how our earth was made and all other things around it, HMMMM, INTERESTING.

600 million tonnes per second is not slow, in my opinion. There is a LOT of it to get through, though...

The gravity of the sun is determined by its mass. If you remove 'a lump' of gas, the gravity adjusts instantly. Likewise, the outward force caused by the fusion reaction is also dependant entirely on the amount of gas present, so this force would also redress itself instantly. How suddenly you remove the gas won't make a difference. What will though, is how much you take. If you remove enough, the pressure will be reduced and the conditions will no longer be sufficient for fusion. You'd end up with a 'gas giant' planet, much like Jupiter or Saturn.
