No it didn't.
Hmm I cannot agree. IMHO the universe is expanding (outwards) and will continue to expand untill the matter totally scatters across the infinity of the universe.
We will cease to exist because the sun will become a red giant who-knows-how-many-million years from now. It will swallow the earth in it's dying breath and unless we flee to another planet - we are doomed.
You start off talking about the expansion of the Universe. You give no logical reason why expansion means that there will never be a reverse of the Big Bang idea. You may as well have said that your favourite clowns are green clowns.
You then said something entirely unrelated about the sun going boom. Why? What evidence suggests this? How can you be sure nothing else will happen first?
These statements are no less logical than what you've said:
* The great Ducklesnot will inject poison into the Earth's core.
* In the year 2007, people with "outey" belly buttons will explode killing everything within a 50 mile radius.
* Mice: Friend or foe? Apocalypse at noon.
