Stumble! Upon: Eleven Things that Fill Me with Awe

Number four:

That there is something rather than nothing.
Why does anything exist? This is what Martin Heidegger called the fundamental question of metaphysics. Awe can arise out of a deep understanding or out of complete ignorance; this question is an example of the latter. Not only do I not know the answer, but I don't even know what form an adequate answer would take. It's possible that this question is incomprehensible to human-level intelligence. Complexity arising out of simplicity, as in the case of evolution, is at least plausible even if miraculous. But simplicity out of nothing? This question may be within the ontological realm (what is true) but still outside the epistemological realm (what can be known). I am not impressed by philosophical attempts to explain existence by invoking a logical or metaphysical necessity, nor do I find claims that the question is meaningless to be persuasive. If an answer is found, I expect it to come from science rather than philosophy. Thomas Tryon's observation that the mass-energy content of universe appears to be zero and so the universe may have arisen as a quantum fluctuation seems like a promising step in the right direction, but even if true this is only a partial explanation, since a vacuum is not nothingness and has physical properties that allow the particles to appear out of "thin air".
