New Images of M87* Black Hole Reveal Shift in Brightness Peak and Confirm General Relativity Predictions

In April 2019, the Event Horizon Telescope (EHT) Collaboration reported the first-ever event-horizon-scale images of a black hole, resolving the central black hole known as M87* in Messier 87 galaxy. In a new paper published on January 24th, astronomers present new images of M87* from data collected by several instruments within the EHT. These new images show the shadow of M87* as predicted by general relativity and reveal that the brightness peak of the ring has shifted roughly 30 degrees counterclockwise around it compared to where it had been a year earlier, which was also predicted by general relativity.

    • The supermassive black hole in the galaxy Messier 87 continues to act as Einstein's theory predicted it would.
    • Two new images of the supermassive black hole M87 were made from observations collected in April 2017 and April 2018. The first image revealed a fiery, slightly lopsided doughnut of hot gas circling a dark emptiness like water circling a drain.
    • The same team of scientists have done it again, this time even better. In 2018, they stared again into M87's darkness with a slightly enlarged network that provided higher resolution. The result shows the same lumpy doughnut and the same central hole in even tastier detail.
    • The brightest lump had shifted roughly 30 degrees counterclockwise around the ring relative to where it had been a year earlier, which was predicted by general relativity.

  • Deception (50%)
    The article is deceptive in that it presents the image of a black hole as if it were an accurate representation of what a black hole looks like. The image shows hot gas circling around a dark emptiness, but this does not accurately represent the nature of a black hole. A true black hole would be completely invisible and could only be detected by its gravitational effects on nearby matter.
    • The article describes the image as showing hot gas circling around a dark emptiness like water circling a drain. This is not an accurate representation of what a black hole looks like.
    • The article presents an image of M87's supermassive black hole as if it were visible when in fact, according to Einstein's theory of general relativity, a true black hole would be completely invisible and could only be detected by its gravitational effects on nearby matter.
  • Fallacies (85%)
    The article contains an appeal to authority fallacy by citing the work of Albert Einstein and his theory of general relativity. The author also uses a dichotomous depiction when describing the black hole as both a 'fiery, slightly lopsided doughnut' and 'a dark emptiness like water circling a drain'. Additionally, there is an inflammatory rhetoric used in phrases such as 'Hello darkness, our old friend,' which may be seen as sensationalist. The article also contains examples of informal fallacies such as the use of colloquial language and contractions.
    • The first image of a black hole looked so similar to the mathematical predictions that it almost seemed like a fluke,
  • Bias (85%)
    The author has a clear bias towards the scientific community and their ability to accurately predict outcomes. The article repeatedly mentions that Einstein's theory of general relativity predicted black holes would act in certain ways and that these predictions have been confirmed through observations. This creates an impression of authority for the scientific community, which may be seen as biased.

          The article contains several fallacies. The author uses an appeal to authority by citing the opinions of multiple experts without providing any evidence or reasoning for their conclusions. Additionally, the author commits a false dilemma by presenting only two options: either M87* is described accurately by general relativity or it is not. This oversimplifies a complex scientific issue and ignores other possible explanations that may be relevant to understanding the observations of M87*. The article also contains an example of inflammatory rhetoric when the author describes the shift in brightness peak as
          • Bias (85%)
            The article contains several examples of bias. Firstly, the author uses language that dehumanizes black holes by referring to them as 'M87*' and 'the central black hole'. This is an example of religious bias as it implies a negative connotation towards these celestial objects. Secondly, the author quotes Dr. Keiichi Asada saying that confirmation of the ring in a completely new data set is a huge milestone for their collaboration and strong indication that they are looking at a black hole shadow and material orbiting around it. This statement implies an endorsement from Dr. Asada which could be seen as monetary bias if he has any financial ties to the EHT Collaboration or other instruments involved in this study.

                    The article is deceptive in that it presents the new image of M87* as a validation of both the original findings and our understanding of black holes. However, this statement is not entirely accurate because while the new image shows similar features to the old one, it was captured a year later with enhancements in the telescope array. The article also states that these data are important for validating general relativity and our understanding of black holes but fails to mention that there have been other studies conducted since 2019 which contradict some aspects of this theory.
                    • The new image was captured a year later with enhancements in the telescope array, not just because it represented the first time humans had imaged a black hole.
