Can science describe what happened as the universe emerged in the Big Bang 13.8 billion years ago? Is "emerge" even the correct word? Can science describe the ultimate essence of physical reality given the inherent uncertainty of quantum physics? Can human knowledge go that far? Or are we bound within an island of knowledge surrounded by inscrutable unknowns?
I'm not entirely sure if these are rhetorical questions or if the author is genuinely curious about the limitations of human knowledge. However, there was a time that humans thought the moon was a God, lesser than the God of the Sun, and the idea of travelling to the moon was both incomprehensible and laughable. Now look where humans are. I tend to assume that that there is no limit to human knowledge, rather, there are probably questions yet to be answered that we haven't even thought of.
