"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

I was that's why I prompted in brackets heh heh

I thought 'The Sun' was made by a printing press.

:)

*Badum-tisch*

to my knowlege the sun is not big enough to go 'nova. in 5 billion years it will swell and engulf mercury and venus and make earth uninhabitable. It would need to be ALOT bigger to go nova. If it was even bigger it could form a black hole. But it isn't.

lol! I'm going for a degree in astro-physics actually, considering i got 98% in my recent Earth and Space test in revision for the Mocks we have in two weeks. Still, back to the topic. :D


I'm not sure that would happen Cubist. You'd have to take (at least) half of the gas from inside the Sun away. Besides, the constant nuclear reactions would prevent any such thing happening, but hey, we can dream.

:D

to my vauge knowledge the sun will turn into a white dwarf star after its done its whole planet engulfing thing
white dwarf is like red dwarf only not as funny :)
*hides constellations wall chart and puts astrophysics book away*

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.

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.

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

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.
