- We don't know or its not possible to know what came before something.
- After Big bang, nothing (as you define it), doesn't exist to the best of our understanding.
We both seems to agree on this two key point. So what are you exactly arguing against?
"We don't know yet." is really the answer to whatever you are mad about. Krauss or pick-your-favorite-scientists doesn't really shy away from this fact.
Are you mad because of the wording "UNIVERSE FROM NOTHING", then you just judging the book by its cover.
>"We don't know yet." is really the answer to whatever you are mad about. .
I explained it perfectly well above, why people are mocking him, I also said the following: "I personally don't care about Krauss either way, if he can make money using such tactics, good on him." so your accusation of being mad is nonsense.
>Are you mad because of the wording "UNIVERSE FROM NOTHING", then you just judging the book by its cover.
I am making clear arguments devoid of any emotions, you seem to be hallucinating. I argued against the deceptive nature of Krauss' formulation of "nothing" which is not nothing, which is not "judging a book by it's cover" it's judging the deceptive nature of his rhetoric, which he has also demonstrated in many appearances on TV. And again, I don't care about Krauss either way, if he can make good money by that, good on him.
What we know is that there is no "nothing" as we understand or define it.
At the end of the video he says "We can't prove that we came from nothing, But it's plausible." from our limited understanding of whats going on in empty space. I don't know why you think "Krauss is often mocked for" this - because this is not unique to Krauss personal interpretation but there is scientific consensus within the community.
We can't tell where quantum fields came from the same way we can't tell for sure what happened before the big bang - other than the fact that we know it happened.
