Is God’s existence still necessary if physics can explain the laws of the universe?


Sir, may nalala lang ako sa Angels and Demons and na curious ako sir. Do physicist like you sir try to diprove that God exist? I mean, that by constantly striving to explain everything that happens and happened in the universe, doesn’t that dispels the idea that God created the universe?


As a physicist, I know my limitations. The equations in physics only describe the physical world. But our equations break down when we try to describe beauty, truth, justice, love–surely these things exist, and no sane man will deny their existence. God created the universe to be well-ordered and well-defined by laws, because God is Logos. All the order and beauty that we see in the universe is only a reflection of who God is. But God can intervene in his Creation. That is why the Incarnation happened–God became man so that man can share in God’s divine life. That is why miracles happen–beyond the laws of physics a water is changed to wine or a leper is instantly cured or a dead man is raised to new life.

But God does not want us to be automatons where all our actions are determined from our previous actions–the foundation of Automata theory in Computer Science. Because of His love, God gave us free will to choose or reject his love. The force of gravity pulls everything downward. But a man on the edge of the cliff has the free will to let go and die or hold on and live. You cannot predict a man’s decision with an equation. That is why conversion is such a big deal for God: He did not force you to convert, yet by your own free will you converted. In a similar way, your girlfriend did not force you to love her, yet by your own free will you loved her anyway. As Christ said regarding the parable of the lost sheep: “There will be more joy in heaven over one sinner who repents than over ninety-nine righteous people who have no need of repentance.” (Lk 15:7)

I hope I have answered your question. If you have other questions, just ask.
