Of course the video supports your confirmation bias where the correctness of the video is unimportant to you but presents an anti-mainstream view despite being riddled with errors.
Theres a lot of unfounded assumptions in what you say including the cosmological principle itself. I think that was Flemmings and the other scientists point that the model itself may be wrong, the assumptions may be out. The anomelies in the BB and CMB are only part of many anomelies that are pointing to the standard model being wrong and as Sabine said she believes the cosmological principle should go and that a complete paradigm shift will happen in the near future based on the data itself. I tend to agree.Here are a few.
(1) The requirement for the earth being in the centre.
Wrong the author doesn’t understand the concept of metric expansion.
The centre can be any point in the observable universe not just the earth, as every point is moving away from every other point.
(2) Expansion of the universe results in a Doppler redshift.
Wrong the expansion of the universe results in cosmological redshift.
Cosmological redshift is due to the Hubble flow of a galaxy and is always along the line of sight of the observer; for Doppler redshift the motion is through space time and usually includes a transverse component or in many cases a Doppler blueshift such as the Andromeda galaxy.
(3) Galaxies, clusters and people should be expanding.
Wrong the reason why galaxies, clusters and people are not expanding is that each exists in gravitationally bound system.
(4) Redshift should cause the “perfect” blackbody spectrum of the CMB to smear.
Wrong the cosmological redshift of the CMB causes the blackbody spectrum to shift to the right along the wavelength axis and a reduction in the peak wavelength which defines the temperature of the CMB.
The blackbody remains “perfect”.
(5) The CMB is local at around 200 million light years according to the paper.
Wrong as I explained in my previous post the foreground is essentially a template and is not the CMB at local scales.
Evidently the author is blissfully unaware the CMB is optically opaque and if it is local then our observable universe is reduced from a radius of 46.5 billion light years down to 200 million light years.
This means the maximum redshift for any object can be no more than z ≈ 0.02.
In summarizing the video is complete utter nonsense.
Enough is enough I am not going to repeat myself about the absence of microwave redshifted galaxies.
This all about confirmation bias as an exercise for intelligent design and all you have achieved is to thoroughly contradict yourself by supporting a crank video which states the observable universe is only 200 million light years across and z ≈ 0.02 is the limit, while simultaneously accepting high redshift data of galaxies where z > 11 as evidence the BB is wrong without considering the galaxy formation process as being suspect.
Just linked it now in my most recent post.Evidence please.
I could give you 10 scientifically (some well known and some scientists don't want to know but nonetheless validated) that demonstrate the video is correct. I linked some of those reasons above #382.@sjastro's post #372 gave five or so valid, scientifically well known, reasons which demonstrate why your video presenter doesn't understand what he's talking about. You can verify @sjastro's points from other qualified astrophysicist commentator sites.
I know enough about astrophysics to know a consistent argument, from a completely ill-informed bogus one.
So, just as a matter of interest, how would you propose to choose between the two viewpoints for yourself? What process would you choose for seeing the forest through all the trees in a situation like this?
I, as a small example of just one, feel quite comfortable with my choices in arriving at my conclusion on this one .. how 'bout yourself?![]()
She does and so does Flemming. They just report the latest findings that seem to contradict the standard model and don't claim any solution. Just more questions and unknowns. Actaully Sabine does mention the 'MOND' hypothesis as a possible alternative but she doesn't say its correct only that it helps explains some of the issues the Concordent model has problems with. But then it raises some problems itself.Upon reflection, I too, am left puzzled about which parts of the current model she thinks might change in any revised model, in order to address the physical dimensions of those new structures(?) I'd say, like the rest of us, she has no idea .. so why not just come out and say that?
Isn't it ironic. There has been a number of times where some have used Sabines analysis because they say its good and independent to support against non standard ideas but when due to that same independent alaysis supports stuff that contradicts the standard model her credibility is suddenly questioned. Typical ad hominem fallacy. So now we have Sabine added to the Crack pot list. Lets see how many other prominent scientists are added in order to prop up the status quo.One is tempted to conclude her motives for producing that video might be to satisfy her sponsors(?)

PS: I'm wondering if there are, as yet, missing observations, from incomplete whole sky surveys?

Referring to Flemming as a scientist is an insult to actual scientists. He is a crank who writes in crank "journals" and makes tons of gross errors.Theres a lot of unfounded assumptions in what you say including the cosmological principle itself. I think that was Flemmings and the other scientists point that the model itself may be wrong, the assumptions may be out.
If the cosmological principle can only be applied at much larger scale it complicates analysis of observational data and will certainly alter some parameters, but it isn't a "complete paradigm shift". As I noted above, the blocking of distant galaxies by our Galaxy will complicate the measuring of variations in the parameters across the sky. (The assumption that things are identical in every direction will be broken.) None of this will alter the nature of cosmological redshift, the expansion of the universe, or that everywhere in the Universe the distant Universe will be expanding away from all observers and increase with distance. These are all gross errors Flemming makes.The anomelies in the BB and CMB are only part of many anomelies that are pointing to the standard model being wrong and as Sabine said she believes the cosmological principle should go and that a complete paradigm shift will happen in the near future based on the data itself. I tend to agree.
Nobody said anything about this regarding a religious position, nor do we care.Besides how it is bias on my part to support theism when all the scientists I have linked are atheists.
Flemming is an unreliable narrator. There is no point getting a summary of a recent result from someone who gets the background grossly wrong.They are just disagreeing based on good science. In fact Flemming was just repeating what was in the paper he referred to.
I'm not sure I'd go so far as unbiased. From her other videos she clearly likes things that poke holes into LambdaCDM.I also included the video from theorectical physicist Sabine Hossenfelder which says the same thing and I have followed her and she is pretty unbiased in her analysis.
Here are some more scientists saying the same thing and its not as if the anomelies with the BB theory and the reading of the CMB map are not well known within mainstream science.

The thing is though, one has to read those papers through the eye of searching for the fundamental Physics any arguments are based upon. Frequently, these fundamentals are missing. Unfortunately there's no short-cuts in acquiring this perspective, other than years of education in Physics.I could give you 10 scientifically (some well known and some scientists don't want to know but nonetheless validated) that demonstrate the video is correct. I linked some of those reasons above #382.
Its not just a matter of outright dismissing the cosmological principle because of a few anomalies .. it takes a lot of direct evidence to do that .. and there isn't sufficient that has been properly confined to that specific target. I think that's probably the boundary line defining 'anomalies', from say 'a body of concrete evidence', come to think of it.That the assumption about the cosmological principle is unjustified based on the current data. That more and more evidence seems to be showing as Flemming said that the CMB map is a localized reading and not a universe wide one as evidenced by the links posted in my previous post and most important because Sabine says so lol.
Cosmology has been driven by the abundance of data (and theoretical) evidence beyond the child-like innocence of philosophical Popperian principles like falsification of hypotheses. Popper didn't like it .. but so what? .. he was just a philosopher.There are others like problems with Dark matter and energy, Inflation theory, the Hubble tension, the S8 Tension, the Horizon problem, the Great Wall, the Giant Arc, the Local Hole ect. But most of all its unfalsifiable which doesn't make good science and in fact to maintain the status of the current standard model it has been complicated to the point it creates more problems and unanswered questions rather than converging on a simple and explanatory theory.
Yeah, you're still talking about a time before there was time.I think it does matter because time itself needs to be understood and explained within the current standard model. Its an unresolved problem for associated with entropy, the low entropy state of the beginning of our universe which is associated with the arrow of time.
An interesting problem has come up with the new discoveries from the JWST is that galaxies are far to big and numerous soon after the big bang. So this is causing scientists to wonder whether the standard model need adjusting or even completely revised. Possible implications are that the beginning of our universe happened much longer ago or even some are saying that the universe may be infinite having no boundary and the same in all directions.
So the idea of time itself, the concept humans have created may need rethinking. I mean there are other reasons like with ideas such as Multiverses where our universe is one of many. So scientists may want to know what was before our universe in developing those theories. I think its an open question and we should not force any particular concept of time or space for that matter.
Okay, please do so. Please give me a list of all the physicists who claimed that time was around before time existed. Please make sure you quote them making this claim, and provide a link to where they made such a quote.So defeating illogic, I can give you a very long list of actual renowned physicists who disagree With you,
A list which you have not provided (and which I doubt you will ever provide.)My question is why do you disagree with such a long and esteemed list of names??
I'm not talking about gravity or matter, I'm talking about time.did gravity precede matter, or did matter precede Gravity?
I'm not talking about gravity, I'm talking about time.Can gravity exist without time?
I'm not talking about gravity or matter, I'm talking about time.So did time prexist gravity and matter.
I'm not talking about gravity, I'm talking about time.Has gravity always Been what we observe, or has it changed? Is it the same everywhere anyway?
I'm not talking about the speed of light, I'm talking about time.Did speed of light prexist light? Has that always been the same?
The point was that the idea of time before time itself is questionable. Its a human made concept.Yeah, you're still talking about a time before there was time.
You can't have a TIME before there was time if time did not exist.
Thats not a good analogy. We can ask what is north of the north pole which may be outter space or a particular galaxy and then ask what is north of that and keep going to infinity.It's like asking what is further north than the north pole.
The findings are just the data, what the experiment or test finds based on the same methodology that has found results supporting the standard model. They just test the assumption of standard model against to see if it stands up.The thing is though, one has to read those papers through the eye of searching for the fundamental Physics any arguments are based upon. Frequently, these fundamentals are missing. Unfortunately there's no short-cuts in acquiring this perspective, other than years of education in Physics.
That is exactly what the researchers did. They did not make any conclusions though for example Sabine mentions the it would make sense for the cosmological principle to go in the light of these findings. But they just highlight the anomelies to show that the standard model has some deep problems that need addressing and then pose the questions.The Cosmological Principle (Homogeneity/Isotropy) is intrinsically intertwined (for evidentiary reasons) in the Lamda CDM model, often in subtle ways. Often single researchers are, themselves, not aware of some of the pitfalls themselves. The honest ones admit that in their conclusions and put their questions 'out there', as a sanity check. The more one understands Astrophysics, the more doubt there is in any conclusions formed .. its a huge field of endeavour with gazillions of human-hours of enormously deep thinking wrapped up in it.
The problem is the anomelies keep mounting. Some are major and would require at the very least a revising of the assumptions made. As Sabine mentions the discovery of the universe expanding at faster rates which was given a Nobel prise was based on a faulty assumption that the cosmological principle is valid on shorter distances down to 100 mpc which is an unjustified assumption. This assumption was inferred for example in the analysis of supernovae data on which the existence of dark energy was inferred.Its not just a matter of outright dismissing the cosmological principle because of a few anomalies .. it takes a lot of direct evidence to do that .. and there isn't sufficient that has been properly confined to that specific target. I think that's probably the boundary line defining 'anomalies', from say 'a body of concrete evidence', come to think of it.
Well as time goes on we will see. The more conflicts and anomelies the more it comes into question. The problem with abundance of data depends on the assumptions made so of ourse you can tweak the data to fit the assumption.Cosmology has been driven by the abundance of data (and theoretical) evidence beyond the child-like innocence of philosophical Popperian principles like falsification of hypotheses. Popper didn't like it .. but so what? .. he was just a philosopher.
The Lamda CDM model isn't just an hypothesis .. its a guiding principle built on Physics.
As she mentions a recent paper Evidence for anisotropy of cosmic acceleration showed that if one analysis the supernovae data correctly without assuming the cosmological principle holds on two short distances then the evidence for dark matter disappears. That paper has been entirely ignored by other scientists. Sabine gives a commentary on this new paper here.
Referring to Flemming as a scientist is an insult to actual scientists. He is a crank who writes in crank "journals" and makes tons of gross errors.

Well Sabine and the papers linked come to a similar finding. As Sabine said referring to the paper that when the cosmological principle is not assumed it removes the need for dark energy. The Nobel price given for the increasingly expanded universe was based on an unjustified assumption so this brings that finding into question which is what the current model is based on.If the cosmological principle can only be applied at much larger scale it complicates analysis of observational data and will certainly alter some parameters, but it isn't a "complete paradigm shift".

OK fair enough I won't refer to him. But I think its unfair that you then cast out the rest of what he said which was also backed up by others.

No thats the point of Sabine she has a lot of videos with mixed findings. I think she likes keeping up with current science and actually dispelling stuff that is not supported by the science. She actually breaks it down, explains things and often leaves the conclusion up in the air.I'm not sure I'd go so far as unbiased. From her other videos she clearly likes things that poke holes into LambdaCDM.
Like I said I won't refer to him as an independent source not because he is not correct on some of the science he referred to which has been supported by others besides himself. But because his record lacks credibility. But that doesn't apply to Sabine and the other physicists in the papers I linked.WARNING: This item comes from the proceedings of a conference full of "alt-cosmologists" and some cranks.

No, time is a measurement. The idea of minutes and seconds may be invented by Humans, but the concept of time is just as real as the concept of distance is.The point was that the idea of time before time itself is questionable. Its a human made concept.
That's increasing in altitude, not going further north.Thats not a good analogy. We can ask what is north of the north pole which may be outter space or a particular galaxy and then ask what is north of that and keep going to infinity.
I'm not aware of any legitimate scientist who claims that time existed before the Big Bang.The same with what humans think time is or was created. The BB says that time was created in the BB and yet we know there was something before the BB which may show something else and this may lead to an infinite regress as well. So theres a lot to investigate. Otherwise we would not bother if we thought time itself was created in the BB.
Cool, but that just makes you wrong too.I disagree.
Not unsupported claims so much as blatant errors. Even if he wasn't a crank his credibility as a science communicator would have been completely busted before he even got to discussing the paper on anisotropy. Anyone with a modest understanding of cosmology (for example someone who'd just taken a freshman survey course) would have stopped watching after a few of those major errors. (@sjastro detailed them for you, so I will not go over them for you again.He made a couple of unsupported claims but the majority of what he said is consistent with what others say in those links such as the remarkable similarities in the dipoles between the local universe and the CMB map.
As a "scientist" he has no credibility to attack. He writes crank physics articles for a crank journal, which I wouldn't have known unless you linked them. So, thanks?Attacks on his credibility don't change that fact.
The Earth is not in the middle and it is not a measurement problem. The Universe is expanding and expanding everywhere. Even with anisotropy in the density and expansion rate, more distant galaxies would *still* be more redshifted at larger distances in every direction and from every place in the Universe.I think he is talking about the earth in the middle is about the measurement problem.
No it doesn't. Not about how the expansion works, and also not about how these new results and analyses work. (Well at least the ones from actual cosmologists.) If the Earth is in a local underdensity or there is a massive structure "nearby" altering expansion a small bit locally does not change the overall properties of expansion, but it might change some of the parameters derived somewhat. This is particularly a problem if the observations are only made in a limited set of directions (such as only in the part of the Northern sky not obscured by the Milky Way.). I would gladly discuss those things with you, but you have latched on to persons promoting fantasy physics and until you give up the guy with his own (laughable) alternative to standard particle physics there isn't any real hope of a reasoned conversation.Because of the assumption of the cosmological principle it sort of assumes the earth or at least our solar system is in the centre to make the cosmological principle work in the light that the new paper and others he is referring to seem to support that the earth or our local universe may well be at the centre according to the tests done.
Even if that paper is correct and the dark energy effect is just a consequence of local anisotropy in the expansion the cosmological principle would still apply just at a larger scale (which we are already seeing evidence of just from the detection of large structures) and the "expanding away from every observer" thing would also still apply.Well Sabine and the papers linked come to a similar finding. As Sabine said referring to the paper that when the cosmological principle is not assumed it removes the need for dark energy. The Nobel price given for the increasingly expanded universe was based on an unjustified assumption so this brings that finding into question which is what the current model is based on.
See post #392 on anomalies.I agree though its not so simple. But I think there have been some major anomelies with the BB and dark matter and energy so its a shaky foundation to be making predictions on.
Stick to actual scientists. The video from Hossenfelder covered the same material. I cast him out an unreliable narrator. I don't know what points he made when discussing the anisotropy paper from Sarkar's group because I stopped watching him because he was so unreliable.OK fair enough I won't refer to him. But I think its unfair that you then cast out the rest of what he said which was also backed up by others. If he's a crank on those other points he highlighted then so are all the others and I think thats a bit of a stretch.
Generally I think her videos are good in content and explanations, I just have some concerns that she *wants* things about standard cosmology to be wrong so her choices in presenting those results on YouTube may imply bigger issues with standard things and more confidence in novel challenges. (At least she didn't fall for that "double age" paper that got a lot of traction from legit science communicators.)No thats the point of Sabine she has a lot of videos with mixed findings. I think she likes keeping up with current science and actually dispelling stuff that is not supported by the science. She actually breaks it down, explains things and often leaves the conclusion up in the air.
First, Sabine Hossenfelder is not the source for those ideas or results. Here she is just a science communicator. Her area is black holes and quantum gravity. Flemming, on the other hand, does claim to have his own models for these things and (if she knew about him) Sabine would rip him apart.But I think this whole idea of trying to discredit the source is a fallacy anyway. First it was Flemming, now its Sabine and I am sure people will keep trying to undermine every source when they don't like the facts. But the content they talk about is based on the science, the testing and data.
So am I.Like I said I won't refer to him as an independent source not because he is not correct on some of the science he referred to which has been supported by others besides himself. But because his record lacks credibility. But that doesn't apply to Sabine and the other physicists in the papers I linked.
For example Sabine Hossenfelder is a well established theorectical physicist with over 80 papers.
Sarkar (who is the last author on the paper) is, as far as I can tell, a particle physicist with only a passing contact with cosmology all related to this anisotropy analysis.Subir Sarkar who she refers to in the paper is Professor Emeritus, Department of Physics at Oxford. While Diego Lambas who Flemming referred to has over 9,500 citations. So if we are basing it on the credibility of the source then I think we can say it passes the test lol.
An adjustment related to changing the scale of cosmological principle (smooth mass distribution)? That's all I'm seeing now and while it does make the metric equations for the evolving Universe a bit messier, the consequences to the general facts don't seem that large.Nevertheless I don't want to dwell on this too much. I am not trying to say there is any clear answer or model but that its developing and that the current model though well supported has some big problems that go deep which need to be determined. If some of these anomelies do stand up then there is something fundemental missing.
One of the (150) citations to the paper from Colin et al. (Sarkar) that is this one that considers the kind of things I was thinking of as the next step -- actually extending the Lambda CDM model from the isotropic and uniform expansion of the FLRW spacetime to one with a simple asymmetry.Some say its just an adjustment and some say there has been many adjustments and perhaps too many for it to be good science.
Is your expertise as great in the rest of cosmology as well?Others say we are heading for a paradigm shift based on the findings. And its not just is cosmology but physics generally.
It reminds me a bit like the biology and evolution debate where some are also saying a paradigm shift is needed to overcome the anomelies.
But we know time is not physical, we can't put it in a test tube so its a created mental concept and not real. Time is fluid according to Einsteins theory of relativity and are effected by gravity and velocity and time is like space within 4 dimensions but what happens to time in QM which is said to be the basis for reality. According to some interpretations of QM we can time travel.No, time is a measurement. The idea of minutes and seconds may be invented by Humans, but the concept of time is just as real as the concept of distance is.
Silly me yes the earth is round and due to its axis all lines on earth converge at the north pole and stop though there is a point higher than the north pole called . But then there is such a thing as the North Galactic Pole which is in the constellation Coma Berenices.That's increasing in altitude, not going further north.
Of course there is. For example the idea that our universe is but one of many rebirthed universes or that our universe in one of many in a multiverse. So before our universe began there were other universes which had beginnings before our universe and had time according to our understanding of time. So the idea of time existed before our time.I'm not aware of any legitimate scientist who claims that time existed before the Big Bang.
