Summary
An analysis of Einstein's derivation regarding the gravitational slowing of time and the bending of light in a gravitational field.
Einstein's Theory of Gravitation and Light Bending
Highlights
Gravitational Redshift
The text explains that clocks run slower in the proximity of massive bodies, a phenomenon that implies light from large stars should exhibit a redshift in its spectral lines.
Light Propagation and Curvature
Based on the general theory of relativity, light-rays are subject to bending when passing through non-constant gravitational fields. The curvature of a light-ray is mathematically derived based on the gradients of the velocity of light.
Calculation of Deflection
The document provides the mathematical framework for calculating the total bending of a light ray as it passes by a mass M at a specific distance, noting that empirical verification of these gravitational effects was an ongoing scientific challenge at the time.
