The James Webb Space Telescope (JWST) is revolutionizing our understanding of the early Universe. In addition to discovering more bright galaxies than expected, JWST has also revealed that supermassive black holes were present in the early universe and may have played a role in galaxy formation.
One study published on February 8th, 2024 by The Astrophysical Journal Letters found that ultramassive galaxies containing supermassive black holes could explain why some of these bright galaxies are so massive. These black holes heat up nearby gas, making the galaxies appear brighter and therefore more massive than they really are.
Another study published on February 14th, 2024 by NASA found that tiny variations in density had a momentous impact on the future structure and evolution of the universe. Regions with greater density attracted more matter due to gravity, eventually leading to the formation of bigger and bigger structures.
Overall, these discoveries are challenging our understanding of cosmology and highlighting the importance of continued research into this fascinating field.
, The galaxy spotted by astronomers was inexplicably bright and incredibly young with respect to the current age of the Universe. It was initially dated to just 250 million years after the big bang, when there should not have been enough time for such a galaxy to have evolved.
, A flurry of reports of other early-Universe galaxies with anomalously high brightnesses emerged, leaving astronomers on tenterhooks as to what they might see next.

The JWST observatory is revealing far more bright galaxies in the early Universe than anyone predicted.

Deception
(50%)
The article is deceptive because it implies that the JWST observatory has discovered something that challenges the basic paradigm of cosmology and contradicts the most frequently used model of the Universe's evolution. However, this is not true, as later in the article it admits that more data has shown that these early-Universe galaxies are not anomalies but rather consistent with previous predictions. The author uses emotional manipulation by creating a sense of excitement and mystery around the JWST discoveries, while downplaying their significance and relevance. This is an example of sensationalism and editorializing.
The article also says that the JWST discoveries were 'a challenge for the basic paradigm of cosmology', and quotes Rachel Somerville as saying 'It was an incredibly exciting time.'
The article states that 'a team of astronomers had spotted a galaxy that shouldn't be there...when there should not have been enough time for such a galaxy to have evolved.'

The article contains a statement that contradicts the established cosmological model. The author states that there is a galaxy inexplicably bright and incredibly young with respect to the current age of the Universe, which should not have existed according to their understanding of cosmology.

The JWST revealed there were supermassive black holes very early in the Universe's history.
Traditionally, it has been assumed that stars and galaxies formed first. But a new analysis of data from the early Universe collected by the James Webb Space Telescope suggests that actually, black holes and galaxies emerged together

One possibility is that these ultramassive galaxies contain supermassive black holes. These black holes would heat up nearby gas, making the galaxies appear brighter and therefore more massive than they really are.

Deception
(50%)
The article is deceptive in several ways. Firstly, the author claims that black holes and galaxies formed together when traditionally it has been assumed that stars and galaxies were here first. This statement contradicts previous knowledge about the formation of galaxies which was based on observations made by scientists who had a fairly decent handle on things until they started to find inconsistencies with their model in recent years. Secondly, the author claims that supermassive black holes present a particular problem because of the way some black holes form from stars but this is not true as there are other mechanisms for forming supermassive black holes such as collisions between these objects. Thirdly, the article implies that huge clouds of matter collapsing directly into black holes without becoming stars in the first place could have been present from very early on and spurring on galaxy formation but this is not supported by any evidence presented in the article.

Fallacies
(85%)
The article contains several fallacies. The author uses an appeal to authority by citing the work of astronomer Joseph Silk without providing any context or evidence for his expertise in the field. Additionally, there is a dichotomy between the traditional understanding of galaxy formation and the new analysis presented in this article, which suggests that black holes and galaxies formed together rather than one before the other. This creates confusion and uncertainty about our current understanding of how galaxies form.

Michelle Starr uses language that implies the traditional understanding of galaxy formation is incorrect and presents a new perspective on the relationship between black holes and galaxies. The author also mentions that there are inconsistencies in previous models with observations made by the James Webb Space Telescope.
But today we see those objects as stars arrayed in gravitationally bound systems we call galaxies, which revolve around a supermassive black hole in their center. Traditionally, it has been assumed that the stars and galaxies were here first.
The beginning of the Universe has always been something of a chicken-and-egg problem
The research has been published in The Astrophysical Journal Letters.
This strongly implies another mechanism for black hole formation: huge clouds of matter collapsing directly into black holes without becoming stars in the first place.
We know these monster black holes exist at the center of galaxies near our Milky Way, but the big surprise now is that they were present at the beginning of the Universe as well and were almost like building blocks or seeds for early galaxies. They really boosted everything, like gigantic amplifiers of star formation

The JWST captured its first glimpse of the early universe and observed more ultramassive galaxies than expected.
Shortly after the Big Bang, tiny variations in density had a momentous impact on the future structure and evolution of the universe. Regions with greater density attracted more matter due to gravity, eventually leading to the formation of bigger and bigger structures.
Accuracy
The discovery of unexpected ultramassive galaxies may not rewrite cosmology but still leaves questions about how the first galaxies formed and evolved.

The article is deceptive in several ways. Firstly, the author claims that the discovery of unexpected ultramassive galaxies may not rewrite cosmology but still leaves questions. However, this statement implies that there are no significant implications for our understanding of cosmology when in fact it suggests a potential conflict with current theories and models.
The article states 'This would upend decades of established science.' This is an example of deceptive language as it exaggerates the significance of the discovery and implies that there are significant implications for our understanding of cosmology when in fact this may not be true.

The article contains an appeal to authority fallacy when it states that the development of objects in the universe is hierarchical and cites Julian Muñoz as a source. The author also uses inflammatory rhetoric by stating that revising the standard cosmological model would upend decades of established science, which could be seen as an exaggeration.
The development of objects in the universe is hierarchical. You start small and get bigger and bigger,

The author of the article is Emily Howard and she has a history of bias in her reporting. The title mentions that these unexpected ultramassive galaxies may not rewrite cosmology but still leaves questions which implies that there might be some sort of conspiracy or deception involved. This statement could be seen as inflammatory and sensationalist, leading to the author's score being lower than it would have been if they had presented the information in a more objective manner.
