Observer-Dependent Theory of Everything
Metatheory spanning all dimensions from d=-1 (sub-Planck) to d→∞ (cosmological). Space H is infinite-dimensional. R = Ô(Ψ) - reality is the result of observing the field of potentialities.
How ODTOE unifies theories
S (0 → 1)
S — degree of internal theory coherence (0 = chaos, 1 = full coherence)
d (1 → 10+)
d — effective spacetime dimensionality of the theory
R = O(Ψ)
Each physical theory is a special case of the equation R = O(Ψ) at certain values of coherence S and dimensionality d.
Candidates for a theory of everything: a comparison
How the main research programmes — from string theory to ODTOE — approach the unification of the fundamental interactions. No approach has direct experimental confirmation.
| Approach | Key idea | Testability status |
|---|---|---|
| String theory / M-theory | Fundamental objects are one-dimensional strings and higher-dimensional branes in 10/11 dimensions; requires supersymmetry. | No experimental confirmation; no superpartners found at the LHC; the landscape of ~10⁵⁰⁰ vacua obstructs unique predictions. |
| Loop quantum gravity | Spacetime itself is quantized: geometry is described by spin networks, with discrete spectra of areas and volumes. | Mathematically developed; predicts discrete geometry at the Planck scale; no direct experimental tests. |
| Causal Dynamical Triangulations (CDT) | Spacetime is assembled from elementary simplices with a fixed causal structure; the dynamics is explored numerically. | Simulations reproduce a four-dimensional de Sitter-like universe; no experimental tests. |
| Asymptotic safety | Gravity remains a consistent quantum field theory thanks to a non-trivial ultraviolet fixed point of the renormalization group. | Evidence from the functional renormalization group is computational; no experimental confirmation. |
| Causal set theory | Spacetime is fundamentally discrete: a locally finite, partially ordered set of events. | Sorkin's early estimate anticipated the order of magnitude of the cosmological constant; no systematic experimental tests. |
| ODTOE | The observer is a fundamental primitive; reality is a configuration actualized by the act of observation: R = Ô(Ψ). | A research programme built precisely as a theory-of-everything candidate: the formalism is published, the empirical programme is in development. |
Data reflects the scientific consensus as of 2026: none of the candidates has direct experimental confirmation.
