They explain in all detail how they arrived at three plausible images and they chose the threefold one as an interpretation of the measurements. There is no error that anyone here could possibly discover. One question that occured to me: If the accretion disk is visible as a ring from earth, it seems to be near orthogonal to the plane of our galaxis. Strange, maybe i have to read the paper.

Unless it's spherical and one is simply seeing a cross section. |

Veritasium may address that here: https://youtu.be/Q1bSDnuIPbo?t=989 |

Here is a muckraking discussion of Dr Robitaille's "pseudoscientific" ideas apart from his training as a radiologist and inventor in the development of MRI, especially ultra-high magnetic field systems: https://rationalwiki.org/wiki/Pierre-Marie_Robitaille I post this only to allow others to decide about his reliability on black-hole imaging. Note that Dr Robitaille's discussion of "Kirchhoff's Law" is not about the "KVL" in circuit theory, but a totally different law about black-body radiation (not to be confused with black-hole radiation). |
