You want to talk about big, check this out: http://www.space.com/scienceastronom...st_object.html

It's an amoeba-like structure some 200 million light-years wide, comprised of galaxies and large gas bubbles.

Prepare yourself: the sun will become a red giant about the diameter of Betelgeuse or a bit larger when it starts to run out of fuel. Then it'll collapse into a white dwarf while blowing off most of its mass into a planetary nebula;

was entering that into my calendar and my blackberry started laughing at me. come on, can't they program a few billion years into a smart device?! not very smart.

Na ah. The sun has far less mass than Betelgeuse, so It won't get that big. It will certainly swell up, but at most it has only enough mass to engulf Earth's orbit, while Betelgeuse actually surpasses Jupiter's in width.
