Einstein said “The most incomprehensible thing about the universe is that it is comprehensible”.
We understand a tremendous amount about how the Universe works and how it came into being. We have established the laws that govern the Universe and we know these laws apply everywhere. We even predicted antimatter and black holes before these things were ever observed in nature.
On the other hand Einstein loved the mystery of the Universe and he also wrote this “The most beautiful thing we can experience is the mysterious. It is the source of all true art and all science. He to whom this emotion is a stranger, who can no longer pause to wonder and stand rapt in awe, is as good as dead: his eyes are closed.”
