Variable Speed of Light

Light.  The first will be to confirm that light is the foundation of each notation.  The key equation from 1899 is:

c=pl:pt You can follow the simple division along line 10.  First we should see what the average is across all 202 notations.   The experimentally defined measurement for the speed of light per second is 299,792.458 km/second.

Our range is awkward; the low of 299,768,509.931 is notation 3. Notation 16 is quite high at 299,982,157. Notation 23 is 299,798,132.04.  It is 299,779,059.777 at 78 and 146. It seems to settle down around 299,773,648.756

There are many theories about variable speeds of light. It would serve us very well to weigh in on this work. Also, this equation should tells us something very new about the difference between visible light and all other manifestations of light.
Conversion to whole seconds from 144 to 202.  Every notation represents time in three ways.  First, it is a calculation about the nature of light within that notations. Second, the age of each notation is the current second less its Planck Time value, so the “age” of each notation is slightly different. Three, all notations share the current time which can be, and will be, computed to the current second based on the most accurate measurement of age of the universe.
