What are the photon/electron consequences of matter in a gravitational time dilation?

Due to gravitational time dilation, for an observer of the planet, the frequency of electromagnetic radiation would be slower. Visible light emitted from the planet would appear as infrared or micro-waves. The amplitude of the radiation would not change. Since frequency decreases while amplitude remains constant, the radiometer would receive less cumulative energy and would spin slower. I do not believe there would be any change in the rate at which an atom absorbs a photon. The speed of light is infinitely faster than mass can travel. Objects inside a massive gravity well absorb photons the same way objects in open space do.

Overcoming Relativistic Effects of Near Speed of Light Travel

As a ship approaches the Speed of Light, Relativistic effects cause temporal issues for its passengers and crew.  Human passengers will not do well finding they have traveled for two years to find a thousand years has passed on Earth.

In order to avoid Velocity Time Dilation due to near Speed of Light travel, Gravitational Time Dilation may be used to compensate for the temporal changes.  A gravitational generator may be placed at the front of a ship.  As the ship approaches the Speed of Light, the gravitational generator will need to increase its gravitational output.  

Increased gravity may be uncomfortable for the passengers and crew.  So to create an opposing force, the ship's rate of acceleration will need to increase as well.
