Do I still have time to mow the lawn?
Depends on how much of an angry busybody your neighbor is. ;’)
Perhaps, but why bother?
From what I've understood for some time, there didn't appear to be enough mass in the universe to halt and reverse the expansion of the Big Bang. (This reversal might be known as the Gnab Gib). If the Gnab Gib can't happen, then the universe would be doomed to eventual heat death as the overall temperature of the universe would slowly approach absolute zero.
Not a pleasant end. IMO.
I like the idea of a Gnab Gib, and the possibility of it's eventual reversal into a new Big Bang. Everything else in God's creation seems to be cyclical, why not the universe itself?.
