Curvature of Light (Continued)
Exploring another possibility of what could possibly enable a light photon to complete a circle of travel throughout the universe would be to examine light refraction, reflection, diffraction, deflection and common light interference, in conjunction with the Photoelectric Effect. An example; from a great distance if planet Earth was miniaturized to the size of a marble, its peaks like Mt. Everest and valleys like the Grand Canyon would disappear, its surface from a distance would appear smooth as glass. Farther along, light photons approaching any non-illuminated planet or body of mass may be repelled by deflection from the planet's surface because its surface could possibly reflect enough light outwardly to repel extra incoming photons. Those planets or bodies of mass may be simply and variably illuminated from distant stars throughout the universe. Although the light may be dim, the outwardly reflected light may be sufficient for the Photoelectric Effect to repel any excess incoming light photons - enabling them to continue their curvilinear journeys. Perhaps that is one reason many planets or bodies of mass remain unseen.
It is further believed the Spherical Mass ("Big Bangs") of the "Big Bang" may act similar to an ovum, birthing light photons with an intrinsic drive to return to their beginnings.
