1John1:5, "God is light". That says it all right here. Light means
more than the small portion of the light spectrum we can see.
Energy is transferred to electrons in atoms by photons, quanta of
light. And then, E=Mc˛, the One Substance whch is timespace itself.
We see a Trinity. Light at light speed, v=c seems to be the
Father. Probability is faster than light, v>c, seems to be the Holy
Ghost. Christ incarnated into matter, v<c, and matter is composed of
closed circuits of the One Substance in the One Substance.
With 1John1:5, "God is light", there can neither be atheism nor
agnosticism. It takes no stretch of the imagination to have faith. The
truth is right in front of you.
