You are contradicting yourself now.
previously you said:
Why are you acting like Krauss should be accepted as the final word in this matter anyway? No all scientists would even agree with his views. And he certainly hasn't shown that anything can be started from Nothing. In fact, he even cheats and claims that "nothing" does not even mean the same thing it used to mean. He now uses the term "nothing" to refer to a space that has Quantum Properties.
A space that already has Quantum Properties is NOT starting from nothing.
So, above you say Krauss talks about a pre-exiting SPACE? And the article I pointed to you is where Krauss says he is not. How is that not contradicting yourself?
But the article you pointed to did no such thing.
It clearly stated that he IS starting with
the kind of nothing implicated by quantum field theory
Here's the quote again, directly from that article:
In January, Lawrence Krauss, a theoretical physicist and Director of the Origins Institute at Arizona State University, published A Universe From Nothing: Why There Is Something Rather Than Nothing, a book that, as its title suggests, purports to explain how something---and not just any something, but the entire universe---could have emerged from nothing, the kind of nothing implicated by quantum field theory.
I even highlighted it in
RED.
Where in this article do you think he says otherwise? Moreover, if he does claim otherwise, then the article itself would be self-contradictory since it clearly states that he's starting with
the kind of nothing implicated by quantum field theory
So what are you taking about. So far I have totally justified my position even using the articles you've pointed to.

My question isn't concerned with how the energy/matter content of the universe can sum to zero, but rather what would have caused it fluctuation from non-zero in the first place? Obviously the laws of QM are pointed to as an explanation, but then where did those laws come from? And what was it that actually fluctuated?
Now you are saying that Krauss is using abstract objects (laws pf physics) to create fluctuations. That is just a poor understanding of science and a redundant argument from you.
It's not. It's precisely what Quantum Mechanics predicts. It's the Heisenberg Uncertainly Principle coupled with probabilities. And that's how they calculate it. I know how they calculate these things I used to these sort calculation myself years ago. It's just an application of the Heisenberg Uncertainty Principle along with some assumptions of random probabilities.

The mathematics of Quantum Theory can show how a universe can spring into existence from quantum fields.
Really? Where is this math then? Can you share this?
It's called Quantum Mechanics, and can be found in a gazillion textbooks on the subject. I'm not about to try to teach you Quantum Mechanics in forum posts.
JohnA wrote:
What on earth is a quantum field? We do not even talk about that in QM at all. You are confusing quantum field theory (QFT) being a theoretical framework for constructing quantum mechanical models of subatomic particles with your imaginary QUANTUM FIELD. That is just laughable. That alone showed me you know nothing about QM. You now changed this post to try and chance your previous posts, but you can not. It is too late, I have your post content. No wonder your posts are so full of contradictions.
You can't have a particle popping into existence in physics without QFT. How are you going to do that?
JohnA wrote:
Actually, I do not even want to respond anymore to you. I agree with your position of the Christian god(s), but that is about it. You lack of scientific knowledge is driving you to formulate your own dogma. Ironically that is exactly the thing you hammer Christians with. That is Ironic.
You haven't shown where anything can be started from NOTHING without using QM or QFT or BOTH.
So it appears to me that you don't have a leg to stand on.
JohnA wrote:
As far as I'm concerned we have no reason to believe that the quantum world is anything other than magical at this point in time. We certainly can't explain it logically. And the math doesn't explain it logically either. The math simply describes probabilities of potential. But like Richard Feynman has pointed out, "Nobody knows how it can be like that".
If the math describes it, how can it not be logical?
All the math describe is probabilities. Moreover, those probabilities DEMAND that things must happen that defy logic.
What are you trying to claim? That someone has an perfectly logical explanation for the behavior of the quantum phenomenon? How about pointing me to that article. That might be interesting to read. Although I've read quite a few articles that claim to achieve that goal when in fact they don't. I think David Bohm has given the best attempt to date, but his description requires that you accept non-locality, and many people do not accept that non-locality is logical.
JohnA wrote:

Krauss is not arguing to start or to have a space (quantum vacuum or whateva)? He says no space, no time, no particles, NOTHING.
The both the article you pointed to, and the video of Krauss lecturing himself both reveal that he is indeed starting with Quantum properties. So what you just said here is simply not true.
JohnA wrote:
And he describes his logic with physics. If he can not describe it with physics then it can not be described scientifically anyway.
But the physics he's using is quantum physics and presumes that all of laws and properties of a quantum space are already in place. That's not starting from NOTHING.
JohnA wrote:
You are basically saying that there is no logic that can describe it, therefore it is not possible, but it is mystical, not only that, but YOUR SPECIFIC mystical. That is absurd.
I don't have a "specific mystical". I'm not arguing for any mysticism. All I saying is that these scientist who claim to be able to start a universe from Nothing are being less then honest. They are starting with the assumptions of both Quantum Mechanics and Quantum Field Theory and that's not NOTHING. So they are being dishonest.
JohnA wrote:
(And Krauss said very clearly in his video that there is nothing mystical about the universe - YOU IGNORED THIS COMMENT FROM ME BEFORE TOO. Want me to send you the exact timing in his video where he said this - want more egg on your face?).
Just because Krauss made this claim doesn't make it true. Krauss isn't God.
Who is Krauss to say whether or not there is anything mystical about quantum phenomenon?
He's already pretending that it's "NOTHING" and now he's pretending that he can say with certainly that there is nothing mystical about it.
He's out of line on both counts. And I'd love nothing more than to discuss this with him personally.

You have not reviewed the Hawking logic at all. Am still waiting for you tell us where it is wrong. You claim to KNOW all MATH, yet you refuse to convince us, to show us where the Hawking math is wrong.
Where did I ever claim that he was wrong? I didn't.
On the contrary I said "Give me QM and GR to start with and I'll create a universe for you too"
All I pointed out is that Hawking also begins with these things, and I highlighted that as well directly from the article that you linked to:
Here it is again:
From that article,....
"In order to understand the Origin of the universe, we need to combine the General Theory of Relativity with quantum theory."
Hawking too openly admits that he's starting with all the assumptions and postulates of QM and GR.
JohnA wrote:
I am skeptical about your claims. It seems to me you just make them and run away when being questioned. WHERE IS THE Hawking MATH wrong? Point it out, tell us what mistake he made?
He made no mistake at all, and I never claimed that he did.
I simply pointed out that he starts with SOMETHING and not NOTHING.
JohnA wrote:
I have stated my case, given you sources, and you have not given anything. All you say is "dah, they are wrong".
I'm saying that YOU are not PAYING ATTENTION to the details of what these gentlemen are openly admitting that they are actually starting with.
JohnA wrote:
Krauss has a logical argument for everything from nothing.
Except his NOTHING is not really NOTHING. He's allowing for the preexistence of Quantum Field Theory.
How many times do I need to post this.
Here it is one more time directly from the article you pointed to:
"the kind of nothing implicated by quantum field theory"
Krauss is starting with
Quantum Field Theory assumed to already be true and functional. He confesses this himself if you PAY ATTENTION to the details of his lectures and articles.
So I'm not accusing him of anything he doesn't already own up to in the FINE PRINT. But in the TITLE of his lectures and articles he claims to be able to show how a universe can start from NOTHING. Starting with Quantum Field Theory already in place is not starting from NOTHING.
It's slight-of-hand deception that he's pulling on people. He is honest enough to confess this in details and the fine print, but he's quick to sweep it under the carpet like as if it's not big deal. He even says, "We need to change what we mean by NOTHING, it's called learning and education".
That's just a cop-out. He's not starting with NOTHING, he's starting with SOMETHING.
JohnA wrote:
Hawking has math for his infinite finite universe.
And I have no problem with Hawking's math.
But here's what Hawking is starting with:
In order to understand the Origin of the universe, we need to combine the General Theory of Relativity with quantum theory.
He's not staring with NOTHING either.
JohnA wrote:
Many other Scientists has the same (logical arguments and logic, and some evidence). Can you name them? Want me to name them and shame you more?
You aren't about to shame me unless you can come up with a scientist who isn't already starting with QM or GR.
Good luck with that.
JohnA wrote:
The Logic and math is in place. Some evidence is available already. Not all evidence has been examined, not all evidence agree with all these logical arguments. Based on the historical success of science it is inevitable and very probably that they will find an answer. The issue is that some of the evidence can not be shown false: you can not show it false, can you? I think that is what is upsetting you, plugging your emotions.
The evidence that is already available is that Quantum Fields must be far more than just a human invention of abstraction if they can bring a physical universe into being.
And that is all that needs to be true for my point to stand.
Apparently you just aren't grasping my actual position if you are still arguing against my position.

Religion has nothing, All they have is logical fallacies.
Mystical explanations is the same as religion's explanations. Say hi to your god for me.
Your paranoia of a mystical reality is no concern of mine.
Everything I have pointed out in our discussion thus far as been TRUE, and I've even verified it using articles that YOU linked to.
All that is left not is for you to understand this conversation and realize that everything I have claimed up to this point about both Kruass and Hawking is indeed TRUE.
I think Hawking is a bit more open about starting with QM and GR. Kruass pretends that he's actually starting with NOTHING whilst playing down in the fine print that his "Nothing" is actually QFT.
Everything I've said this far has been correct and true.
Now it's just a matter whether or not you're willing to own up to it.
