The Dual Sheet Model (DSM) proposes two spacetime sheets - Sheet 1 (observable) and Sheet 2 (hidden) - connected by a coherence field ψ_C, altering General Relativity (GR).
The model's equation includes terms representing the two sheets, the coherence field, and a novel test involving weak lensing.
The aim is to detect weak lensing effects induced by ψ_C in data from the Euclid satellite and the Dark Energy Survey, providing unique insight into the model.
DSM, an extension of bimetric gravity, introduces a scalar field ψ_C evolving with a specific equation, involving inter-sheet coupling.
Weak lensing, a method measuring galaxy shape distortions to map mass distributions, forms the basis of this proposal.
While standard models predict lensing with a single metric, DSM suggests additional shear due to interactions between the sheets.
Anomalies in lensing power spectra could potentially be observed as a result of these interactions.
The 3D simulation of ψ_C showcases dynamic coherence patterns, which serve as the foundation for this observational test.
This proposal provides a new way to test the DSM's dual-sheet hypothesis, offering insights beyond traditional cosmological frameworks.
