Causality of brane universe via the general bulk-based formalism with a non-zero Schwarzschild mass
In brane-world scenarios, electromagnetic waves (EMWs) are confined to the brane, while gravitational waves (GWs) can propagate through the bulk spacetime. This fundamental difference has been exploited in multiple cosmological studies to address some issues, such as the well-known horizon problem....
