Gravitational deflection of light in the Schwarzschild–de Sitter space-time
Gravitational deflection of light in the Schwarzschild–de Sitter space-time
Recent studies suggest that the cosmological constant affects the gravitational bending of photons, although the orbital equation for light in Schwarzschild--de Sitter space-time is free from a cosmological constant. Here we argue that the very notion of a cosmological constant independent of the photon orbit in the Schwarzschild--de Sitter space-time …
