Now we are working on anti-matter bombs. Or even something less violent, maybe a generator powered by anti-matter that will significatly decrease the cost of electricity. Now all it takes is one oops to destroy the world. One bomb accidently goes off during production. Or one generator in one part of the world malfunctions. Now 500,000 years isn't that long for the universe. Now just think about it, what are the chances of not even one little oops in the next 500,000 years? Assuming of course we make it that long.
btw, I wrote this just for discussion. beleive it or not I am actually an optimist too.
Yes we very well could blow up the planet. But that wouldn't be good for anyone. So it would most likely be an accident and not intentional. I think we very well can survive long enough to find a way off this planet and a way to start up another planet.
