there's a 5th state of matter too right?

No. It's neither solid, liquid, or gaseous. It's surface is considered plasma (4th state of matter).

Is sun solid?

No, our star is nowhere near large enough. Right now we can definitely say it will become a white dwarf. After that, we think it will become a black dwarf. A black dwarf is a theoretical celestial body which is essentially a white dwarf which has cooled enough to no longer emit light or heat. No emissions means that this type of star is invisible, and so cannot be confirmed to exist (yet).

Our sun will be roughly the size of earth at this point. It will have roughly half its current mass, this will mean it will have about 150,000 times the mass of the earth. Most likely, this will cause strange orbits to occur in the outer planets and cause them to be ejected from our solar system.

it would become something like black hole?

Ah, I see. Our sun won't go supernova since it's not big enough. It's a G-type star. It will continue burning H until all the H is depleted, the it will become a red giant as it fuses the He core collapses under its own mass. The sun will then fuse the He into C. Once the red giant phase is nearing its end, the sun will eject much of its matter and turn into a white dwarf. The white dwarf will burn the remainder of the He and eventually go dark.

I did ask. I said 'i suppose' and you're supposed to tell me wether it was true or not since you are the science guy here.

Psychdave, till then even our bones and remains would be dissolved. What do you expect to see in the future btw? like around.... 2500 to 3000 ?

If we can't find a way to travel through space in the next few billion years, we deserve to burn. Lol

World is doomed as it will be consumed by the sun ,however the human race isn't necessarily screwed..

none of those would mean the "end of the world". It may be the end of humans, but the world will go on without us if we kill ourselves before the sun or some other cosmic event does.

Well I can see your where your coming from but I was thinking more along this:-pollution seems to have swallowed up the world, political instability,war and global warming.

These factors are already here and I don't think we'll continue to be here for another 5.4million years.So the question is this...Can these factors be reversed?

The blast of the sun will release energy as energy can form mass by the relation e=mc^2 so the energy would end up into mass and would form new celestial bodies. I suppose.

Through spectral analysis we know the chemical make up of the sun. So we know how much Hydrogen there is. We know the rate of nuclear fusion and we know what happens when the sun burns through the H and the core collapses under the weight of the He. From that we can extrapolate that the Red Giant phase will begin about 5.4 billion yrs from now.

And how do you know that?

2 years, 3 months ago

sure. In 5.4 billion yrs the sun will turn into a red giant and burn earth to a crisp.

the world is going to end on the day North Korea breaks the ceasefire.
