Time and tide wait for no man

So, the world did not end. But what if it had?

Last night I came across a question. "If the world were to end tomorrow, would be be happy with what we've achieved?" To be honest,  I did not even think to answer that question, but another popped into mind. If the world were to end tomorrow, would anybody care what we've achieved? After all, it would be as if somebody hit the big red reset switch...

Another question is 'what does the end of the world entail exactly?'. I mean, a zombie apocalypse isn't the 'end of the world', it is the 'end of the world as we know it'. Does the power just go out like in Revolution? Does a disease wipe out almost all of human population like in Jeremiah? Why do people believe the human race would survive the end of the world? It appears folly to think that people would survivea nuclear holocaust and the nuclear winter thereafter. How many people are required to repopulate the species?

In any case, there are some safe facilities built for the purpose of withstanding extreme conditions and sustaining life within. The problem lies in their size and the speed at which these places can be populated and sealed. Whatever happens that ends the world, it isn't going to be pretty.
