Request for permission to share a post from astronomy.stackexchange.com

[marcin]

I'm asking for this permission because I want to attract as much attention as possible to the lack of the basic, scientific integrity of Astronomy and Astronomy Meta Stack Exchange trying to conceal a fundamental error in cosmology. I've managed to share my post on openastronomy.org's chat, physicsdiscussionforum.org and scienceforums.net. Unfortunatelly, the whole thing is not just a single post, but 3 interleaved posts and consists also of my screenshots of the discussions deleted by moderators in attempt to conceal what I'm showing.

I put all my life and academic authority into this request - Master of Science in Physics majoring in Mathematic and computer modeling of physical processes - University of Warsaw, Poland.

That's the problem - sharing a link to the external source is against the guidelines. Am I allowed to do that in this case?

Sure. Apart from the links to the posts on astronomy.stackexchange.com, I would be pasting a public links to the screenshots of the discussions.

I will really think about. Thank You.

My pleasure. If you have any other questions, please ask.

Is it acceptable?

I am not going to get into a long debate on this, your maths is flawed and so is your reasoning, but you are not alone in that, it is a complex topic nthat has many "rabbit holes" one can get themselves lost in.

However, in the last few weeks a paper has been published by Antonia Seifert, Zachary G Lane, Marco Galoppo, Ryan Ridden-Harper, David L Wiltshire in The Monthly Notices of the Royal Astronomical Society entitled Supernovae evidence for foundational change to cosmological models which calls into question the need for Dark Energy.

The new evidence supports the "timescape" model of cosmic expansion, which doesn't have a need for dark energy because the differences in stretching light aren't the result of an accelerating Universe but instead a consequence of how we calibrate time and distance.

It takes into account that gravity slows time, so an ideal clock in empty space ticks faster than inside a galaxy.

The model suggests that a clock in the Milky Way would be about 35 per cent slower than the same one at an average position in large cosmic voids, meaning billions more years would have passed in voids. This would in turn allow more expansion of space, making it seem like the expansion is getting faster when such vast empty voids grow to dominate the Universe.

Follow the link that is the paper title to read for yourself. It is open access so you do not need an instituitional login for this paper.

@Jim Franklin There's more than that, it's more fundamental and rock solid.

• [arXiv:2406.05050] The Dark Energy Survey Supernova Program: Slow supernovae show cosmological time dilation out to z∼1
• [arXiv:2306.04053] Detection of the Cosmological Time Dilation of High Redshift Quasars

Thank you for your company in the whole misunderstanding, I don't feel so alone anymore.

I also recommend this video:

Btw. You could really use quotation marks when you're quoting someone's article.

 

[Gibsense]

0=(cdt)^2-dr^2
Your saying that the radius of the universe = the age of the universe (?)

Also You mentioned Cosmic Time Dilation ( I have not heard sorry, seen, the phrase before: How would you define this please. I ask because in various threads over the last year I have suggested that the curvature of space may have a similar effect to the curvature of a gravity well producing time dilation. In my case this becomes pronounced at great distances but , if I understand your post, you were talking about a flat universe.

 

[Gibsense]

Indeed, "my" observable universe radius is equal to the Hubble radius or the light travel distance, but I'm not saying it just like that.

Well, it is interesting because I have for about 20 years. But at that time they kept shooting me down even though they could not understand how the 'Age of the Universe' could describe the Hubble Constant so well.

I edited in a further question to the post; it was concerning 'Cosmic Time Dilation'. Not a phrase I had heard before but it may correspond to a suggestion I made about a year ago on this Forum; that universe curvature might show time dilation similar to the dilation from the curvature of a gravity well but I think you were talking about a flat universe. (?)

Cosmic = Cosmological. The difference in the flow of time depending on the universe age, caused by the expansion.

I really recommend this video.

That's the same thing.

Yup, "my" universe if flat and that's because its cosmological age is the same at all distances from us if neglect the timescape, that are the differences in the matter density of the universe causing the different flow of time. My assumption is still based on a large scale homogeneity.

Well, it is interesting because I have for about 20 years. But at that time they kept shooting me down even though they could not understand how the 'Age of the Universe' could describe the Hubble Constant so well.

I'm your living incarnation and I know how you felt.

 

[Gibsense]

I'll have a look at the video. There are a lot of theoretical consequences if this is correct.
Aha! Yes exactly that, I think I have seen it before maybe.
Well, not quite that. It was ok explaining 'Cosmic Time Dilation' (nice description) on the basis of high gravity (a gravity well) but on a Cosmic scale, she does not explain where the equivalent gravity well is.

I suggest it results from curvature - not a black hole - but the shape of the universe (maybe gravity and curvature are the same thing even on a cosmic scale). Anyway to make this work it finally dawned on me that the observable universe would have to approximate the actual universe. Not a very appealing conclusion. I'll post the drawing that illustrates how we might misinterpret the data here for convenience shortly if you are interested, however-

In a separate thread, I discussed a Torus as a possibility for the shape of the universe having imagined a transition via a black hole. It now seems possible that the small circle of a Torus can provide the necessary curvature and still allow a massive unbounded 3 Torus universe that is Topologically Flat. (This remains an issue between myself and Jim Franklin but the discussion has been limited).

My mathematics is not good enough bye the way I rely on visualisation (if there is such a thing)

 

[marcin]

For some reason, the post appears inaccessible at this time.

I hope you can see it now.

But anyway I am asking Marcin how he would say it in response to his "I'm not saying it just like that". Just numbers?

Λ⋅g_μν must be equal to κ⋅T_μν with the CMB radiation energy density in T_μν, so Λ⋅g_00 must be equal to κ⋅T_00. That's because Λ⋅g_μη=κ⋅T_μη for a flat, but expanding spacetime.

I'll have a look at the video. There are a lot of theoretical consequences if this is correct.

I know

 

[Gibsense]

We seem to be getting posts with different sequences. My last one posted seconds ago predates your last one. no matter, lol

Along the cosmological time axis.

I suggest it results from curvature - not a black hole - but the shape of the universe (maybe gravity and curvature are the same thing even on a cosmic scale).

The greater energy density, the slower the time flows. CMB and all other radiation's energy decreases with the expansion.

 

[Gibsense]

CMB and all other radiation's energy decreases with the expansion.

That makes sense to me. Maybe energy density can be linked to shape but will park that for now. Whatever you have cheered me up!

 

[marcin]

It's linked to shape like 1:1. We can neglect cosmological constant within the galaxy - it's not expanding. In this case the Einstein field equation(s) tell us, that physical stress-energy (SEM) tensor must be proportional to the geometric Einstein tensor describing the spacetime curvature at each spacetime point. Good luck to anyone, who wants to have a non-zero, geometric curvature expressed by the Einstein tensor without the corresponding gradient of energy density in SEM tensor at each spacetime point.

Whatever you have cheered me up!

Same here thanks to You
