Part 5/11:
Typically, physics constructs a model of the world by dissecting it into its elementary components. However, in quantum mechanics, these components—whether particles or fields—exist in quantized states that exhibit perplexing properties like fundamental uncertainty and entanglement. This may still imply a tangible framework, yet the physicist Anton Zeilinger proposes a shift to an informational framework, whereby the universe is seen as a collection of informational components.
Zeilinger suggests that quantum systems can be broken down into propositions, which are essentially answers to specific questions about the physical world. In this view, a quantum system does not represent the world in itself but our knowledge and information about it.
