Quantum entanglement, wherein a measurement on one particle instantaneously determines the spin state of another, challenges the locality and causality principles in four-dimensional spacetime. I hypothesize that two entangled electrons are unified as a single higher-dimensional object across compactified extra dimensions (5th to 11th dimensions). Embedding the entangled wavefunction ψ(x₁, x₂) = (1/√2) [|↑⟩₁|↓⟩₂ ± |↓⟩₁|↑⟩₂] into an extended configuration space X = (x₁, x₂, y₁, y₂) with a delta-function constraint δ(y₁ - y₂), I interpret entanglement not as nonlocal influence, but as a manifestation of geometric unity in higher dimensions. I further develop a higher-dimensional Schrödinger equation to describe the dynamics: iℏ ∂Ψ(x₁, x₂, y, t)/∂t = ( -ℏ²/2m₁ ∇²_{x₁} - ℏ²/2m₂ ∇²_{x₂} - ℏ²/2m_y ∇²_{y} + V(x₁, x₂, y) ) Ψ(x₁, x₂, y, t) My model offers a geometrical reinterpretation of quantum entanglement as projections of a single coherent higher-dimensional entity and suggests new pathways for understanding quantum foundations and spacetime structure.
