Close orbit to Milky Way black hole

  1. When you jettison the spatial unreality of a point sized object or singularity from the math and assign an actual size to your mass in question, you do not get a 'black hole' in a given space time. When you spread that mass of 4 million solar masses across a spherical volume "20 million kilometers" in cross section you do not get anywhere near the infinite density required to 'curve your space time' as proposed in Hilbert's black hole conjecture.

    I am not debating against massive gravitational bodies being possible, that would be observationally untenable. I am debating against anything that has no size whatsoever being assigned mass or density, when clearly this is ridiculous both logically, mathematically, and observationally.

    Anything with massive gravitation you can't explain does not by default become a 'black hole', anymore than any large massive particle you can't actually detect directly become a 'Higgs boson'...even if you desperately wish it were so and your paycheck depends upon it.
