A novel theory proposing that dark energy emerges from anti-gravitational tension in higher-dimensional spacetime, manifesting as a projection of extrinsic curvature from a higher-dimensional matrix field into our 3D+1 spacetime.
Higher-dimensional anti-gravity as dark energy
The Anti-Gravity Dark Energy Field (AGDEF) theory proposes that dark energy emerges from anti-gravitational tension in higher-dimensional spacetime. Rather than being a uniform repulsive force, it's a projection from a higher-dimensional matrix field that manifests as repulsive curvature in our 3D+1 spacetime.
Our observable universe is modeled as a 3D brane embedded in a higher-dimensional space (4D+1). The dark energy we observe is a byproduct of the extrinsic curvature from this brane's embedding in higher dimensions.
Anti-gravity is defined through negative eigenvalues of a metric tensor extended to higher dimensions, behaving inversely to General Relativity's stress-energy tensor: instead of curving spacetime inward (like mass), it curves it outward.
