Gravity as the Architect of Reality: A Paradigm Shift Toward Unified Physics
Rethinking quantum foundations by modifying QM with gravity offers a path to unified theory, overlooked in hype around string theory.
The New Scientist piece highlights physicists like Angelo Bassi reconsidering quantum mechanics by embedding gravity to resolve the measurement problem and wavefunction collapse, rather than quantizing gravity. This inverts decades of string theory and loop quantum gravity efforts. Analysis reveals missed connections to Roger Penrose's objective reduction model, where spacetime curvature induces collapse at the Planck scale, and experimental proposals like diamond levitation test gravitational decoherence. Synthesizing Bassi's Trieste group work (peer-reviewed in Nature Physics, 2023, n=small tabletop setups with limitations in scaling to macroscopic masses) with Penrose-Hameroff ideas shows a potential paradigm shift: gravity not as force but selector of classical reality. No sample sizes apply here as this is theoretical with proposed experiments; limitations include lack of direct evidence and untestable regimes. Unlike preprints, these build on peer-reviewed collapse models. This frames quantum gravity as emergent from classical gravity selecting definite states, bypassing unification via particles.
Bassi: Tabletop tests of macroscopic superposition under gravity could falsify standard QM within a decade if collapse scales are observed.
