The universe,' he continued, 'this universe that we know, began in almost absolute simplicity, and it has been getting more complex for about fifteen billion years. In another billion years it will be still more complex than it is now. In five billion, in ten billion--it is always getting more complex. It is moving toward ... something. It is moving toward some kind of ultimate complexity. We might not get there. An atom of hydrogen might not get there, or a leaf, or a man, or a planet might not get there, to that ultimate complexity. But we are all moving towards it--everything in the universe is moving towards it. And that final complexity, that thing we are all moving to, is what I choose to call God. If you don't like that word, God, call it the Ultimate Complexity. Whatever you call it, the whole universe is moving toward it.
