Later this year, the Planetary Society is planning to launch
LightSail-1, a sail that will travel farther and farther into space
propelled by the sun's steady stream of photon particles. Other
such flights are projected for the next few years. This renewed
interest in light and its momentum call for a fresh look into the
speed of light c which generates this energy. This speed has been,
for over a century, a cardinal pillar supporting the present
edifice of theoretical physics, but that light had any speed at all
was discovered only in the seventeenth century, and confirmed in
the eighteenth, by means of measurements over vast astronomical
distances. These methods seem to have proven that the speed of
light varied with the speed of the observer. Nonetheless, another
experiment late in the nineteenth century, was interpreted as
showing that the speed of light was independent of its observer or
its source-it was a universal constant. This thesis is a meticulous
examination in historical context of the evidential data and
theories which paved the road to the idea that the speed of light
was a universal constant, a seemingly universal belief. The need
for the endeavor arose secondarily to the main task of exploring
fundamental physical and geometrical phenomena of light detailed in
the previous treatises on Optokinetics.
