Why All That Can Happen, Will Happen... Eventually.
Whether you are Murphy Brown, Charlie Murphy, or the bassist to the Dropkick Murphys, the universe finds a way to do whatever the hell it wants. It may seem as though the universe conspires against some of us and give everything to others, there's a little thing that you should remember, in any of it's many ways to be said.
Anything that can go wrong, will go wrong.
(The general way of saying the universe is just an envious little prick.)
If anything just cannot go wrong, it will.
(The pessimist way of looking at things.)
Things get worse under pressure.
(Thermodynamically speaking, of course, but has a tinge of humanity to it.)
Mother Nature us a spiteful bitch.
(The capitalist and non-environmentally minded way.)
In a world without this wonderful law, would there be any reason to nearly anything? If we knew exactly how everything was going to come up, imagine how boring and predictable our lives would be. Our ancestors would have lived without being marveled by the thought of traveling to space since they attempted to fly once and it didn't pan out.
A universe without that ray-sho (ratio, and a shout out to my favorite professor) of random outcomes to any instance in our lives would have gotten us nowhere real quick.
