Quantum Field theory has been adopted as a metaphor for that which is not Real, but merely Potential, or logically Possible. The mathematical "points" in the field are described euphemistically as "Virtual" particles. In calculations, they are treated as-if real, even though they are only potential : not yet realized. The "nothing" that preceded the Big Bang Birth of our world may be compared to the un-real Statistical Probability of a mathematical Field. The field is characterized by Logic, but not Matter. :smile:Why is that something that must be/quantum field there? While it's possible there's no explanation possible, I think that to ever get a satisfying answer to the question "Why is there something rather than nothing?", we're going to have to address the possibility that there could have been "nothing", but now there is "something". — Roger
however, there is something and so a lack of anything could not have been the case, — PoeticUniverse

This "nothing" would be it; it would be the all. It would be the entirety, or whole amount, of all that is present. Is there anything else besides that "absolute nothing"? — Roger
If we say the laws of math, logic and physics exist always in some sort of Platonic realm, where is this realm and why is it there instead of nothing. — Roger
Note -- In QT, some external "excitation" or "perturbation", such as a Measurement or Choice triggers the transformation from Virtual to Actual, or Potential (hidden ; implicit) to Explicit. — Gnomon
What I'm trying to do is to imagine getting rid of everything in the universe and then trying to extrapolate what would be there if we could also get rid of the mind. — Roger
That should have been "there is something and so a lack of anything could not be the case". Introducing the past tense confuses the issue by introducing time.
It's not legitimate to jump from "there is something now" to "there has always been something". — Banno
One answer to such existential ontological questions is that, if anything exists now, something must have always existed. For Realists that bottomless Tower of Turtles is called the "Multiverse", more of the same forever. But a more philosophical answer is that the Potential for a new world must have always existed in the ideal realm of Possibility. And infinite Potential exists ("is there") because of Logical Necessity : being implies prior existence.↪Gnomon
But I think the question remains. Why is quantum field theory, logic or statistical probabilities there? If we say the laws of math, logic and physics exist always in some sort of Platonic realm, where is this realm and why is it there instead of nothing. — Roger
Sounds like "spooky action at a distance".They as real although brief make for the Casmir effect. — PoeticUniverse
So, they're not even real enough to be virtual??? :joke:No, the virtuals can't become particles; they don't have the full quanta. — PoeticUniverse
Yes. But I wasn't referring to the Effect, which is an empirical observation. It's the Cause that's uncanny. For example, both Newton and Einstein were perplexed by the implicit "spooky action at a distance" of Gravity. That's because such a sucking force was not allowed in their realistic mechanistic paradigm, where a pushing force was transmitted by direct matter-to-matter contact. A come-hither pulling force smacked of witchcraft.Sorry, one cannot diminish the Casmir effect by saying ""Spooky". — PoeticUniverse
I agree that your logic is impeccable. Yet, intelligent people still disagree on the details of exactly what that essential "Something" is, Ontologically. Is it a material Thing like a self-organizing planet? Is it an immaterial Force like Chi? Or is it an immortal Wizard like The Great OZ behind the curtain? I have my own notions on the subject, but others may disagree, depending on their idiosyncratic worldview, or their communal mindset. :smile:So, Something had to ever be, it having no alternative, with no option not to be, with no opposite, and with no possibility of it coming from the impossible ‘Nothing’. The Something, then, is eternal, in that it is uncreated can never go away. It is Permanent as the Causeless Cause of what comes forth of it, which can only be temporaries. — PoeticUniverse
Democritus calls this "void". Spinoza calls this "natura naturans". Emmy Noether mathematically demonstrated this to be "fundamental symmetries" (of the vacuum) from which Conservation Laws were then derived. QFT further extrapolates to the "true vacuum". These are commensurable examples of physical not-something (not metaphysical nothing(ness)) and, therefore, non-physical / im-material / super-natural woo-of-the-gaps (e.g. Platonism) is not needed – certainly because woo explains even less than contemporary fundamental physics. :mask:... intelligent people still disagree on the details of exactly what that essential "Something" is, Ontologically. — Gnomon
he was the one who applied the scare-word "spooky" to "diminish" another concept that defies common sense. — Gnomon
Is it a material Thing — Gnomon
gravity is an illusion. In part, it is associated with a quantity called “curvature” — Gnomon
Perhaps, and contrary to all our intuitions, something can come out of nothing, given enough "time", which didn't exist prior to the big bang, supposedly. — Manuel

Get involved in philosophical discussions about knowledge, truth, language, consciousness, science, politics, religion, logic and mathematics, art, history, and lots more. No ads, no clutter, and very little agreement — just fascinating conversations.
