--- Quote from: TimFox on May 13, 2022, 09:20:40 pm ---No, that is "Rorschach". I also know what "wank" means. I'm not surprised to see a forged image on YouTube. See section 5 of the paper I cited which discusses the reconstructed images. By the way, you seem to agree with Einstein, who in 1939 also found black hole solutions to his GR equations disturbing, dare I say "icky"? https://www.jstor.org/stable/1968902?seq=1#page_scan_tab_contents --- End quote --- I don’t understand Einstein's paper. And i don’t understand section 5 of that M87 image paper. What i do understand is that my aether theory says that blackholes are impossible. Its like this. An object cannot achieve a speed of c/1 through the aether. Hence, aether cannot achieve a speed of c/1 when the aether flows into an object (eg the surface of a star)(or supermassive body). If light propagates at c/1 through the aether, & if the aether flows into a body at less than c/1, then light can escape, albeit slowly. https://iopscience.iop.org/article/10.3847/2041-8213/ab0c96/pdf https://www.scientificamerican.com/article/the-reluctant-father-of-black-holes-2007-04/ http://old.phys.huji.ac.il/~barak_kol/Courses/Black-holes/reading-papers/Einstein1939.pdf http://www.ptep-online.com/2011/PP-24-15.PDF Five Fallacies Used to Link Black Holes to Einstein’s Relativistic Space-Time Douglas L. Weller E-mail: physics@dougweller.com For a particle falling radially toward a compact mass, the Schwarzschild metric maps local time to coordinate time based on radial locations reached by the particle. The mapping shows the particle will not cross a critical radius regardless of the coordinate used to measure time. Herein are discussed five fallacies that have been used to make it appear the particle can cross the critical radius. |

There's a nice Veritasium video about the image and how the data to create it was generated. Might be easier to swallow than the actual physics paper. |

To Aetherist: Your theory states that black holes are impossible. A very large-scale experiment shows that Sag A* has all the features expected of a "supermassive" black hole. Perhaps your aetherial theory does not agree with experiment in gravitational systems. (I was referring to sections 3 and 5 of the Sag A* paper, but there is similar material in the earlier M87* paper.) |

These do not have to be very massive to semi-trap light. I agree with Einstein that light slows near mass. Hence the escape velocity of a body duznt need to be c/1 if light is to be trapped, the escape velocity needs to be c'/1, where c' is slower than c. Hence as i said bodies do not have to be very massive to semi-trap light. Previously i said that the aether inflow to a body can't attain c/1, i should have said c'/1. Hence even tho the speed of light is slowed near the body, the speed of aether inflow is also slowed, hence i can still say that a blackhole is impossible. |

Or, as Galileo might have said, "yet, they exist". (Yes, I know that the original quotation is apocryphal.) Of course, this is how theories are tested in real physics. |
