Computers are famous for being able to do complicated things starting from simple programs.
All physical systems can be thought of as registering and processing information, and how one wishes to define computation will determine your view of what computation consists of.
One of the things that I've been doing recently in my scientific research is to ask this question: Is the universe actually capable of performing things like digital computations?
I would suggest, merely as a metaphor here, but also as the basis for a scientific program to investigate the computational capacity of the universe, that this is also a reasonable explanation for why the universe is complex.
In this metaphor we actually have a picture of the computational universe, a metaphor which I hope to make scientifically precise as part of a research program.
In order to figure out how to make atoms compute, you have to learn how to speak their language and to understand how they process information under normal circumstances.
Similarly, another famous little quantum fluctuation that programs you is the exact configuration of your DNA.
Science consists exactly of those forms of knowledge that can be verified and duplicated by anybody.
According to the standard model billions of years ago some little quantum fluctuation, perhaps a slightly lower density of matter, maybe right where we're sitting right now, caused our galaxy to start collapsing around here.
Nothing in life is certain except death, taxes and the second law of thermodynamics.
