The Angels of God

Is light a particle or a wave? It is paradoxically both. Light is beyond any easy classification, it is a mystery an enigma. And it is used as a great metaphor in Christianity.

"What is true here in the physical realm, is true in an incomparably greater degree of the spiritual realities and of God. Only by circling around, by looking and describing from different apparently contrary angles, can we succeed in alluding to the truth, which is never visible to us in its totality."

Scientific discovery does not only offer distinct ideas when the truth requires it. It also reveals the mysteries deep within physical reality. And faith professes the ultimate mystery, which is God. But the mysteries of God raise the mind to adoration. The become the light of the mind itself, illuminating the meaning of human life itself, to live in the love of God and neighbor, creating communities of truth, communion, and light shining before the world. Darkness will never prevail against that light, for it radiates from the risen Jesus.  The Heavenly city to which we journey, St. John tells us in his prophetic vision, had no need of sun or moon to shine on it, for the glory of God gave it light, and its lamp was the lamb—the lamb whom all Christians profess as God from God, and light from light.  

Nearly all of the information we have about the universe comes from light; but how does that light get made? What can it tell us about these astronomical objects? What is light?
