God Is the Machine

At today's rates of compression, you could download the entire 3 billion digits of your DNA onto about four CDs. That 3-gigabyte genome sequence represents the prime coding information of a human body — your life as numbers. Biology, that pulsating mass of plant and animal flesh, is conceived by science today as an information process. As computers keep shrinking, we can imagine our complex bodies being numerically condensed to the size of two tiny cells. These micro-memory devices are called the egg and sperm. They are packed with information.

That life might be information, as biologists propose, is far more intuitive than the corresponding idea that hard matter is information as well. When we bang a knee against a table leg, it sure doesn't feel like we knocked into information. But that's the idea many physicists are formulating.

The spooky nature of material things is not new. Once science examined matter below the level of fleeting quarks and muons, it knew the world was incorporeal. What could be less substantial than a realm built out of waves of quantum probabilities? And what could be weirder? Digital physics is both. It suggests that those strange and insubstantial quantum wavicles, along with everything else in the universe, are themselves made of nothing but 1s and 0s. The physical world itself is digital.
