fifthmonarchyman: spoken like a true materialist. It was a question. Box (quoting third-hand criticism): For one thing, physicists themselves, including Krauss and Hawking, do not treat the laws of physics as if they were either logically necessary That's the question which physicists are trying to answer. The Big Bang suggests a state beyond matter, energy, space and time. Study of the singularity may or may not yield to scientific inquiry. In any case, you have apparently abandoned the fine-tuning argument, so that is something. fifthmonarchyman: The vaccum was thought to contain aether ... But it doesn't, of course. fifthmonarchyman: ... and it certainly contains potentiality Even in classical physics, an enclosed vacuum is not so simple as it can transmit electromagnetic radiation. fifthmonarchyman: I’m not wedded to these terms you could call it flubber if you like just don’t call it nothing because it is not nothing The term nothingness is probably already established, though once it is better understood, it might be modified appropriately, perhaps as the 'nothingness of the singularity'. kairosfocus: I repeat, simply: a quantum vacuum hosting fluctuations etc is not non-being. So you keep repeating and repeating and repeating, and no one contests. The original conception of the vacuum was that it was nothingness. The idea that space and time could be bent or even not exist was not something people grasped before relativity theory.Zachriel

KF:
The basic point is made: nothing, is just that. No-thing, non-being.
As a dualist, I have to disagree with this definition. If nothing is the true opposite of something, then it must exist by logical necessity. Since this is equally unacceptable, I must conclude that our concept of nothing is flawed. In my view, NOTHING is EVERYTHING and vice versa. ONENESS is NOTHINGNESS. This is why zero, unlike all other numbers, is neither positive nor negative but both. It is the sum of everything positive positive and negative. At the Zen master said to the hot dog vendor, "Make me one with everything." :-D Regarding the so-called quantum fluctuations of the vacuum, it is important to understand that there are no plausible hypotheses in mainstream physics to explain the fluctuations. The materialist/atheist is fervently and religiously hoping that fluctuations are proof of matter being spontaneously created out of nothing but the evidence does not support their wishful thinking. Causality is not something that you can mess with and go home to brag about. There are strong reasons to suppose that we live in a 4-dimensional "spatial" universe and that our entire visible 3-d universe of ordinary matter is moving at c in one the 4 dimensions. We can only see a miniscule and fleeting 3-d slice of the vacuum at every instant. In other words, we are continually experiencing the appearance and immediate disappearance of a succession of 3-d vacuum slices at every instantaneous Planck time. The fluctuations are simply the result of our sudden collision with particles that are already in the 4-d vacuum. Just saying.Mapou

FFM: velikovskys asks What are your qualifications to make that judgement ? I say, I know that something is not nothing. "So something from nothing is not in Krauss’ field of expertise. In fact his comments show he knows next to nothing about the subject." What do you know about how "something comes from nothing" to be so sure that Krauss is mistaken scientifically about the origin of the universe? After all that is the only area that his scientific expertise is relevant. As for Incarnation perhaps I misunderstood your view, Thought you believed it was necessary for the spirit to become part of that which it creates in order to create that which it creates, that nothing has to be something before something can be created from nothing.velikovskys

Feser on Kuhn's criticism of Krauss:
Having for the sake of argument described a scenario in which not even space-time or mass-energy exist but the laws of quantum mechanics do -- he calls this “the physicists’ Nothing,” and it is essentially what Krauss and Hawking have in mind in their accounts -- Kuhn writes: What physicists contemplate -- the sudden emergence or “tunneling” of universes from “Nothing” -- is fascinating and indeed may be cosmogenic, but the tunneling process or capacity is not Nothing. The Nothing of physicists is thick with the complete set of the laws of physics, and so between the physicists’ Nothing and Real Nothing lies a vast, unbridgeable gulf. Moreover, Kuhn does not regard the fundamental laws of physics, whatever they turn out to be, as a plausible terminus of explanation. For to be that, they would have to be either logically necessary or an inexplicable brute fact, and neither supposition is credible. Writes Kuhn: I doubt I could ever get over the odd idea that something so intricate, so involved, so organized and so accessible as the laws of physics would be the ultimate brute fact. I would add that it is crucial to emphasize that the point by no means rests on mere intuition. For one thing, physicists themselves, including Krauss and Hawking, do not treat the laws of physics as if they were either logically necessary or a brute fact. For they regard such laws as empirically testable, which would make no sense if they were logically necessary (i.e. the sort of thing the denial of which would entail a contradiction). If they can in principle be falsified, then they are not necessary.
edit: Laws must relate to something. Hence there is something other than laws present in the 'physicists' Nothing'. By their own admission something unstable and complicated.Box

fifthmonarchyman: The 4 steps to insanity That's hardly insanity. You might consider it conflation. However, if someone were to show that the absence of matter, energy, space and time was unstable, that would be a significant finding, and would have a bearing on the origin of the Big Bang singularity. It's just speculation, of course, and the reality is probably even stranger than that. fifthmonarchyman: 1) Define nothing as everything but X What would you prefer to call the abstraction entailing the absence of matter, energy, space and time?Zachriel

Okay, The basic point is made: nothing, is just that. No-thing, non-being. Including, not a spatial field with vacuum energy and quantum fluctuations, with a reasonable argument pointing to a huge energy density. Or even, taking the alternative low density route, energy is still energy and space is still space. Obviously, such is something, not nothing. But it is obvious that we are seeing scientism, the assumption that all serious knowledge comes dressed in a lab coat. Hence, the disinclination to listen to philosophers and others who listen to them (even if we may have the right to the lab coat and may also glow faintly blue-green in the dark). Net result is, one most easily slips over into a less than thought-through philosophical -- esp. metaphysical, epistemological and logical -- view when one traipses in blindly. But, blind scientism so easily leads to clinging to the absurd. So, again, let us remind ourselves that the notion that "science is the only begetter of truth" etc is an ill-informed philosophical claim and is self-refuting. In that context, let us therefore see that regardless of how rhetorically convenient it may seem to re-label a hypothetical quantum vacuum spatial domain as "nothing" by virtue of the fact that we are discussing something (even something with spatial extension) it is just that, something. Nothing, again, is non-being, and error dressed up in a lab coat is still error. Amazing, that this has to be hammered home so hard, over and over again. KFkairosfocus

CharlieM @465:
Mapou @ 443: You are mistaken, IMO. If the material universe comes from spirit, then it would be spirit. It isn’t. Rather, it is more correct to say that the material universe was caused to exist by spirits with creative powers. There should be no doubt as to there being a distinction between matter and spirit. In fact, they are opposites.
Mapou, your logic doesn’t hold up. If a liquid comes from a gas, then we don’t say that it is a gas. I never said that there is no distinction between matter and spirit. Matter is to spirit as ice crystals are to the water from which they form. In areas such as the voids in space and within atoms there may be no physical substance, but IMO we would be wrong to say that there is no spirit.
Your worldview is so different from mine, I see no point in continuing this discussion. Hopefully, we'll talk again in the future. I mean, you're talking about "voids in space and within atoms" but I don't even believe in the existence of such things.Mapou

Feser: Lawrence Krauss’s book A Universe from Nothing managed something few thought possible -- to outdo Richard Dawkins’ The God Delusion in sheer intellectual frivolousness. Nor was my First Things review of the book by any means the only one to call attention to its painfully evident foibles. Many commentators with no theological ax to grind -- such as David Albert, Massimo Pigliucci, Brian Leiter, and even New Atheist featherweight Jerry Coyne -- slammed Krauss’s amateurish foray into philosophy. Here’s some take-to-the-bank advice to would-be atheist provocateurs: When even Jerry Coyne thinks your attempt at atheist apologetics “mediocre,” it’s time to throw in the towel. Causa finita est. Game over. Shut the hell up already.

I say, I know that something is not nothing. you say, I thought you believed it was necessary for the Spiit to become Incarnate in order to create the material world. I say, well I believe that incarnation and creation are intimately related. In fact I believe that the incarnation is a major perhaps a primary reason for the creation. I would be willing to entertain an argument that incarnation is necessary for creation.

Box: Indeed. Krauss discusses the nature of the vacuum, including quantum fluctuations. Furthermore, he discusses how philosophers use the term, and whether or not removing space and time is sufficient to render it nothingness in the philosophical sense. He considers all of this, then argues that science has changed the playing field by operationalizing the abstract concept of nothingness.Zachriel
