When Norm talks about the doomsday clock he and I have overlaping notions. I see the universe as running a system I call probability balance. That is to say that creation at some point in time is always offset by destruction — stars are born and stars die.
Now the fact that we humans are a creation of the universe, no matter how hard we try, we cannot escape the universal law of probability balance, the negative offset of course being the bad part — peace offset by war, love offset by hate, etc. And now with massive nuclear weapons stockpiled on hair trigger alert around the globe awaiting a technical glitch or political miscalculation to offset all of humanity’s marvelous creations along with humanity itself, we stand helpless against what, for us, must be the final offset. Probability balance requires that the doomsday clock remain on countdown till the end.
