The bending of light and the cosmological constant
Kayll Lake
TL;DR
This paper investigates how the cosmological constant affects the bending of light in Kottler space, concluding that it does not alter light deflection under certain conditions.
Contribution
It clarifies the conditions under which the cosmological constant does not influence light bending in Kottler space, contrasting with its effect on perihelion advance.
Findings
Cosmological constant does not change light bending in Kottler space under specific conditions.
The effect of the cosmological constant on light deflection is negligible in the examined scenarios.
Abstract
The bending of light in Kottler space (the Schwarzschild vacuum with cosmological constant) is examined. Unlike the advance of the perihelion, the cosmological constant produces no change in the bending of light. In this note we examine the conditions under which this statement holds.
