i've heard it said that the universe is still expanding.
1: is this true?
2: how do you know this?
3: how FAST is it expanding? (km^3/hr)
4: what is it expanding into?

and to seperate those in the know from alsorans: how much water could you add to the sun to put out the "fire"? (i already know this one. i know it's a LONG answer, but a couple KEY points will do)

please note, this is not homework. i'm a trucker, not a student.

I think it would be highly interesting if Nasa could get something to orbit around it. They could study it alot more than just when it passes by. Is it possible?

I need to calculate the speed at which the sun is travelling around the central bulge of the Milky Way Galaxy. Use the equation : speed = distance/time. Assume that the Sun travels in a circular path of radius 1.38 x 10^17 km, taking 225 million years for each trip around the central bulge. How do I do this?
