I took a decent dive into this book about "nothing" by a leading cosmological thinker, but is was a long time ago. There is a lot of developed thought on the subject - and I am surprised at the "gee whiz" here on this forum. https://bookpage.com/reviews/1817-j...est-ideas-about-origins-universe#.WXisQojys2x Testing demonstrates that there is a non-zero probability that fluctuations - which come from no Physical source - cause physical effects. ie. Casimir Effect Or - you can say that "nothingness" that is outside time and space - is Physical. Either way, there exists a "physical" paradox in the minds of men, yet nature performs perfectly and originated just fine.
