What does Einstein's 'spooky action at a distance' mean for reality? | Alyssa Ney

Quick Overview

The metaphysical lesson of quantum entanglement is interpreted in two primary ways: as "spooky action at a distance" implying instantaneous non-local influence, or as a consequence of a deeper, high-dimensional reality where entanglement manifests as correlations across spatial distances.

Key Points: The first metaphysical lesson often drawn from entanglement is "spooky action at a distance," where quantum systems instantly affect each other across vast spatial distances, which conflicts with special relativity. The second answer suggests that entanglement is a manifestation of a deeper reality described by a high-dimensional wave function evolving in configuration space, eliminating the need for action at a distance. The high-dimensional view, defended by David Albert and the speaker (Alyssa Ney in her book, The World in the Wave Function), posits that the low-dimensional reality we observe emerges from this higher-dimensional structure. The 2021 Nobel Prize recognized physicists (Alain Aspect, John Clauser, and Anton Zeilinger) who experimentally confirmed Bell's predictions, solidifying the reality of quantum correlations. In the high-dimensional view, the wave function for N particles lives in a 3N-dimensional configuration space, which is fundamentally more complex than describing particle positions in ordinary 3D space. The speaker argues that the higher-dimensional approach resolves the apparent conflict between quantum mechanics and relativity by showing that the correlations are a consequence of the fundamental wave function's evolution in a higher-dimensional space, not faster-than-light signaling.

Context: The speaker, Alyssa Ney, a philosopher of science, addresses the metaphysical implications of quantum entanglement, specifically addressing Einstein's famous characterization of it as "spooky action at a distance." The lecture contrasts this intuitive, but seemingly problematic, interpretation with an alternative metaphysical framework rooted in the mathematical structure of quantum mechanics: the idea that reality is fundamentally described by high-dimensional wave functions, making entanglement an emergent, local phenomenon within that higher reality.
