…does it occur to you that there may be other
videos? By golly…I did actually point out that very thing!!!!!!
But you were replying about the video debate that I posted, i.e. this one
https://www.youtube.com/watch?v=h0YtL5eiBYw
And in the very next post (no other intervening posts to complicate what anyone was referring to), you posted a direct reply (quoting the whole of my post) in which your very first line of reply was to say the following -
Carroll’s claim boils down to this: That there is no known medium or mechanism that could account for NDE’s / OBE’s etc., and that if they were to occur they would be detectable. This is utter garbage…especially for a qualified physicist (thus I question his credibility…with good reason).
So you were most definitely talking about what Carroll said in that particular video (not what he might have ever said at some other time in some other place).
And what I said to you about that very first remark of yours (which is highlighted above in bold), is that I don't recall him saying any such thing. And I pointed out to you that it was Novella who was the one mainly replying on that point of what Neuroscience now "knows" about patients reports of NDE's, and that unsurprisingly Carroll was not disagreeing with what Novella had said about it.
What Novella said, and what Carroll agreed with, is that in fact medical science has long ago, and many times, reported and discussed the detection of brain activity (by MRI scans and the like) displayed when a patient reports a so-called NDE. Explaining that, Novella also said that they can now reproduce the same sort of images in the patients brain by a variety of quite simple means such as starving the brain of blood &/or oxygen, drug treatments, electrical manipulation etc.
I do not know if Novella is correct to say that, because I myself have not been personally involved in any such medical or neuroscience research, and I have not read the papers describing those experiments. And I did not try tell you that I had ever examined any such brain research myself. Instead what I pointed out to you was that when in the film the moderator asked their opponents if they disagreed with Novella, iirc (and I used that same caution of saying "iirc" when saying this to you before) their opponents did not so much dispute what Novella had said, but instead claimed they too had published "scientific" evidence showing that human conciousness does in fact persist after the person dies.
However, as they were making that claim, the moderator asked them to explain which research evidence they were using, and after some moments hesitation & prevarication they suggested a book of some 800 pages in which several authors said to be experienced medics and "scientists" (of some sort? what sort?) declared their acceptance of such claims of conciousness surviving after death ... asked what the basis of the authors belief was, they then admitted that it was a combination of believing anecdotal stories from various patients who claimed NDE's, together with the authors accounts of how they had interviewed psychics and mediums who had convinced them that they were able to contact the spirit world!
On the issue of Sean Carroll possibly saying that he knows anything as a matter of absolute certainty from established theories in science - after that particular video (ie the link above), there have been at least 3 others linked here, and I've watched at least the entirety of two of those (the other two that I linked), as well as several other videos of Carroll talking about quantum theory in general, and I did not notice in any of those videos Carroll ever claiming that
"there is no known medium or mechanism that could account for NDE’s / OBE’s etc., and that if they were to occur they would be detectable". As I say, on the contrary, Carroll knows from Novella, if not from his own research (which is generally nothing whatsoever to do with neuroscience), that NDE episodes are not only detectable, but are apparently reproducible in what iirc Novella said was "exact detail"; so Carroll knows that perfectly well, and he did not disagree with that when Novella was saying it.
Most scientists are usually extremely careful to point out that since the discovery of Quantum Mechanics in the 1920's, we cannot really ever say that anything that physically happens in this universe was, or is, a literally "certainty", as a 100% "fact". So in serious discussions, most genuine research scientists, and particularly theoretical physicists like Sean Carroll, are usually very careful to avoid saying that their results are a matter of absolute literal "certainty". Although, of course in more general conversation and as a matter of expediency they may use phrases such as "we know X, Y, Z", when they really mean we think X, Y, Z are definitely true because the evidence is overwhelming.
Richard Dawkins for example often says "evolution is a literal fact". Personally I would not say that even about the evidence for evolution. But as far as I can tell, the likelihood of evolution being completely wrong, is billions-to-one against ... because the evidence is now completely overwhelming.
Similarly, in one of those other videos, Sean Carroll did address the specific point of what science can or cannot establish as a "fact", and the nearest he came there to asserting an absolute "certainty" was to say that some of our present knowledge of the universe is not ever going to be entirely discarded in the future, although it may very well be improved and altered etc. And he gave the example of saying that the table in front of him was always going to be known as being composed of what we now call "atoms", and that would also be the case a million years from now (he said), but what probably will change and what has already changed a great deal in the last 100 years since the discovery of sub-atomic particles, is our understanding of the best way to describe what "atoms" actually are; their properties, the number of sub-particles, their representation as "fields" etc.
But in saying that, it was obvious from his phrasing, that even there Carroll was expressing his own personal opinion about whether in a million years time science would still have any notion of "atoms".
