"For the heavens will vanish away like smoke,
The earth will grow old like a garment,
And those who dwell in it will die in like manner;"

Sooner or later for sure Tony. The sun is destined to burn-out and explode.
In the near future? Who's to say? 2000 plus years...and counting.

Nuclear termination? It's an odd thing to wish for.

Question: When spoken...did "heavens" mean the solar system, the galaxie, the entire universe...or all of the above and whatever else that we cannot currently see?

All out Nuclear war would not destroy the entire universe. Not even our solar system. Not even a neighboring planet.
Maybe just Huntsville, Decatur and the greater Tennessee Valley area? wink
