I still believed in God (I am now an atheist) when I heard the following question at a seminar, first posed by Einstein, and was stunned by its elegance and depth: “If there is a God who created the entire universe and ALL of its laws of physics, does God follow God’s own laws? Or can God supersede his own laws, such as travelling faster than the speed of light and thus being able to be in two different places at the same time?” Could the answer help us prove whether or not God exists or is this where scientific empiricism and religious faith intersect, with NO true answer?

It’s no wonder about the timing – tragic events, such as pandemics, often cause us to question the existence of God: if there is a merciful God, why is a catastrophe like this happening? The idea that God might be “bound” by the laws of physics – which also govern chemistry and biology and thus the limits of medical science – was an interesting one to explore.
