Physics of information

The exploration of what physics has to say about randomness and reality invokes information as a central concept.

Quantum physics broadened the notions of randomness and reality in physics suggesting a two-way connection between physics and information:
> Physics is informational and that information is expressed in terms of physical randomness.
But what about predictability: does God play dice?
> Information is physical and that information defines physical reality.
But what about objectivity: is the moon still there if you don’t look at it?
