One of my favorite movies of all time is Men In Black. I love everything about it. It makes me laugh, it makes me cry, it makes me laugh until I cry... and believe it or not, as silly and outrageously impossible as most of it is, it makes me really think. 

How much do we really know about the world, and worlds around us? Not as much as we like to pretend we know - and deep down, we are all aware of that. It is that unknown that allows us to truly suspend disbelief when we read about things such as werewolves, or 5th dimensions, or time travel, or flying monkeys. It is precisely because we know we don't know everything, and we know we never, ever will that we are able to believe in what seems at first to be impossible. Einstein believed in the impossible - then he proved the possibilities, and time has proven him right, over and over and over.

Men In Black. That movie really makes me think. I think of possibilities...
Agent Kay explained it best when he said:
"Fifteen hundred years ago everybody knew the Earth was the center of the universe. Five hundred years ago, everybody knew the Earth was flat, and fifteen minutes ago, you knew that humans were alone on this planet. Imagine what you'll know tomorrow."
