The General Theory of Relativity proposes the
slowing of time near massive objects like Black Holes. This occurrence in Relativity creates another phenomena associated with massive bodies in the universe. Light and all other electromagnetic waves have wavelengths that are associated with them which define the properties of the wave. This wavelength is related to a frequency as well as the time period of the wave. General relativity shows that time runs at different rates depending on the density of the space-time curvature, this means the wavelength of a wave will change as time changes near massive bodies. As a wave propagates through changing space-time curvature the wave itself will change wavelength, and therefore change properties. The wavelengths of the visible spectrum range from 400 to 700 nanometers(violet to red light), as time slows wavelengths decrease and as time speeds up wavelengths are stretched. If light propagates out away from a Black Hole time speeds up and its wavelength is shifted to the red end of the spectrum, the light received far from the Black Hole is a different color then when it started. This is called Gravitational Redshift. |

These are two identical programs for calculating
Gravitational Redshift. The one uses a graphics library only supported at Syracuse University computer clusters, and the other is a boring dos version which can be run anywhere. |
