Our galaxy!

wow...my brain hurts now. what I think is interesting is that someday, millions of years from now, our sun could end by exploding or caving in on itself, or it could turn into a BLACK HOLE!!!!! creepy. what also confuses me is that the entropy of the universe must always get bigger or stay the same. weird huh?

Well that's the truth of it all. The sun will explode but not for billions of years and we will definately be long gone by then.

Actually, the Sun in only half way through its life... (Or main sequence stage, at least?)
It will become a red giant, and become bigger, engulfing the Earth. It will then become a planetary nebula then white dwarf, and then after that, a black dwarf. (Which is when it has NO energy left). It is not the kind of star that becomes a black hole, although that would be pretty cool. ^^

Turquoise-> I heard that scientists proved that it would just explode and destroy everything then it will become a black whole afterwards... I could be wrong but that's what I heard.

Well, after it finishes its "Red Giant" phase, it will explode to become a white dwarf, then a black dwarf.

The stars that become a black hole are ones that are first formed with higher mass, then become supergiants eventually, then after a while become black holes after they too, explode.

Though it is weird to think about what is going to happen to our galaxy in a couple of Hundreds of thousands of years time. But I am sure it is nothing for us to worry about because we will be long gone at that time X3

The Sun has been around about 5 billion years, and it has about 5 billion more to go. I'm pretty sure that none of us will be around by then.

Not starting any ugly theme but, I think humans earth and well our planet will by destroyed by ther stuff not by exploding sun.

I find it kind of depressing that the apocalypse is going to be in 6 billion years or so, unless a meteor or something gets us before then... because that's about when the sun expands into a the red-giant phase and the earth's gonna be burnt like toast D:} I read that in National Geographic... *stares at sun that now seems ominous*

(Correct me if I'm wrong on the years thing. I can't remember that kind of thing for my life.)

I'm quite an astronomy freak myself, so I'll be stalking to see if any good conversation develops. ^^[/bookmark]
