Dimension-by-Dimension Evidence

What each work's passages reveal about its stance on each of the six dimensions.

Time

Quantum: The Search for Links

The 1989 Tokyo foundations-of-quantum-mechanics symposium.

Space

Quantum: The Search for Links

The relational, observer-participatory space of the it-from-bit picture.

Matter

Quantum: The Search for Links

The matter constituted by observer-elicited yes-or-no answers.

Observer

Quantum: The Search for Links

The observer-participant whose questioning constitutes the it-world.

Energy

Quantum: The Search for Links

The information-theoretic energies of the participatory universe.

Information

Quantum: The Search for Links

The bit-level binary distinctions from which the universe is taken to emerge.

Internal Tensions

Where each work's argument pulls against itself.

Quantum: The Search for Links

The "it from bit" doctrine has been variously assessed — defenders see it as proper foundational philosophy of physics, critics see it as unfalsifiable speculation.
