Hugh Everett III

1930–1982
American physicist; originator of the relative-state (many-worlds) interpretation of quantum mechanics

The universal wavefunction — all measurement outcomes are realized in branching parallel worlds

Dimension-by-Dimension Evidence

What each persona's writings reveal about their stance on each of the six dimensions.

Time

Hugh Everett III

Branching: every quantum measurement causes the universe to branch; observer-time is uni-directional within each branch but the universal wavefunction admits branches at every event.

Space

Hugh Everett III

Non-local through entanglement, as in the standard quantum formalism.

Matter

Hugh Everett III

Non-local substantival matter; the wavefunction is the complete physical description.

Observer

Hugh Everett III

Plural observers, each in their own branch; multiple time-instances and space-instances through branching. No metaphysical agency.

Energy

Hugh Everett III

Standard physics.

Information

Hugh Everett III

Information conserved at the universal-wavefunction level; personal soul not.

Internal Tensions

Where each persona's working synthesis strains against itself.

Hugh Everett III

Bohr's personal dismissal of Everett's thesis at Copenhagen (1959) consigned the interpretation to twenty years of obscurity. The probability problem (how does the Born rule arise in a deterministic many-worlds picture?) remains contested despite Deutsch-Wallace decision-theoretic derivations. Critics argue that branching itself is a vague predicate; defenders argue that decoherence makes it precise enough.
