A Brief Editorial About Light Speed

As an initial ansantz, light is the prime example that one is to generally think of -- when one is here to be talking about electromagnetic energy.  Light in a vacuum on earth -- when this is here to be taken into consideration of, by both the motion and the gravitational influences of our said earth, to where such inferred influences are here to work to effect the relative rate of such light -- works to help such said light, to travel at a velocity of 2.99792458*10^8 meters per second, under the just implied Cauchy-related conditions.  The fastest speed that electromagnetic energy (when not including Kirchoff Radiation), is capable of traveling at in a vacuum, is at a rate of 3*10^8 meters per second.  Furthermore -- the overall average rate in which light may be propagated at through a vacuum, -- is at a rate of 2.999999985*10^8 meters per second.  To Be Continued!  Sincerely, Samuel David Roach.
