    Yet you have come up with an inadequate answer to my question .

    Only from your limited understanding of science.

    Yes, river, only from your limited understanding as you have shown.

    OK, explain why you believe BH's do not exist in your best scientific way with evidence of course. I won't hold my breath though.

    First gravity is considered extremely weak .

    Tell me different .

    And the effects of gravity are accumalitive per every atom, molecule, particle. But again, this is simply more stuff that you have been informed about in past threads.
    Then as a star collapses it has three stages, EDP [White Dwarfs, NDP [Neutron stars] and finally BH's.
    The next thing that needs to be considered is the Schwarzchild limit or radius. As GR tells us once matter falls at and beyond this density, further collapse is compulsory, at least up to the quantum/Planck level where GR is not applicable.

    Some more educational tips for you river, since I'm feeling rather bouyed at this time....The Schwarzchild limit of the Sun is about 3 kms, so squeeze that mass into that radius, and voila, a BH!! [But of course that will not happen as the Sun is no where near massive enough to undergo such dramatic collapse..

    Using the Event Horizon Telescope, scientists obtained an image of the black hole at the center of galaxy M87, outlined by emission from hot gas swirling around it under the influence of strong gravity near its event horizon.
    Credits: Event Horizon Telescope collaboration et al

    The stunning new image shows the shadow of the supermassive black hole in the center of Messier 87 (M87), an elliptical galaxy some 55 million light-years from Earth. This black hole is 6.5 billion times the mass of the Sun. Catching its shadow involved eight ground-based radio telescopes around the globe, operating together as if they were one telescope the size of our entire planet.



    “This is an amazing accomplishment by the EHT team,” said Paul Hertz, director of the astrophysics division at NASA Headquarters in Washington. “Years ago, we thought we would have to build a very large space telescope to image a black hole. By getting radio telescopes around the world to work in concert like one instrument, the EHT team achieved this, decades ahead of time.”

    To complement the EHT findings, several NASA spacecraft were part of a large effort, coordinated by the EHT’s Multiwavelength Working Group, to observe the black hole using different wavelengths of light. As part of this effort, NASA’s Chandra X-ray Observatory, Nuclear Spectroscopic Telescope Array (NuSTAR) and Neil Gehrels Swift Observatory space telescope missions, all attuned to different varieties of X-ray light, turned their gaze to the M87 black hole around the same time as the EHT in April 2017. NASA’s Fermi Gamma-ray Space Telescope was also watching for changes in gamma-ray light from M87 during the EHT observations. If EHT observed changes in the structure of the black hole’s environment, data from these missions and other telescopes could be used to help figure out what was going on.

    Not sure if you will understand this river and I am releuctant to put it in speudoscience, but I'm a real nice bloke so I'll help you whenever I can. Only 9 mins long river.....

    You not being convinced is not here nor there river and matters not. I mean, you know, you are river and we are all awake to you..

    Pad a non-spinning blackhole !!! Please !

    You mean a plain old Schwarzchild BH river? Well while the BH being modelled is spinning, it is also the state that all BH's would be in. A Schwarzchild model is simply used for mathematical simplicity...you know that language of Physics you dismiss? So we have the realistic model, a Kerr metric BH and that which is present at Sag A.

    ps: I really don't believe you have watched the video river and are just trying to appear *cough, cough* knowledgable.

    But you are convinced that you understand what is going on here from a particular theory , fine .

    And you try to convince me that you are right .

    I understand well the video I posted yes. Convincing you that I am right? No trying to knock into your big fat head that you are a nobody that continually posts bullshit and makes unsupported claims, and no matter how much evidence I or anyone else can present, it will not make an iota of difference...hence why you are banned from the science forums, and have had to revert to skullduggery to continue with your unsupported knoweldge you may have read in some worthless anti science book.

    And when you return, everything will still be the way that the evidence shows, supporting the BB and evolution of spacetime, SR and GR as well as the BH's which GR predicted a 100 years ago.

    Energy as well.

    What does this have to do with the thread topic?
