Apparently a vacuum is the space between my ears. I have not a clue about any of this stuff you write about.
I remember Robert Ringer's "Great Iceball Theory".
6. Ice Ball Theory
a. In 50 billion years, the sun will burn out and the Earth will be a frozen ice ball. Nothing you do now could possibly matter then. So don’t take yourself too seriously. Life is a game, and play to win. There’s no reason to be afraid to be aggressive or take chances. The reality is that there’s no way you’re going to get out of this thing alive, so why play conservatively.
