The Separation of Light and Darkness

This is a sequel to my previous video. We will focus on one particular aspect of sunsets, that last few moments when the field of light passes overhead on its journey toward the horizon. And the possibility that this barrier between light and darkness may in reality be the outer reaches of one single photons life cycle, a blip in time that lasts for only a fraction of a second yet propelled it over 6,000 miles to its end.
