    Black Holes -- Problem and Solution.

    Scenario - A
    The Milky Way's Monster Black Hole Has a Cool Gas Halo — Literally
    By Charles Q. Choi June 05, 2019
    ------
    At the center of our galaxy lies the supermassive black hole
    Sagittarius A*, often abbreviated Sgr A*. This giant is about
    4 million times the mass of the sun and about 14.6 million
    miles (23.6 million kilometers) in diameter.
    ---
    Around Sgr A* swirls a ring of debris known as an accretion disk.
    The gas within this disk experiences so much friction that it can
    reach 18 million degrees Fahrenheit (10 million degrees Celsius),
    according to researchers on the new study. Previous research has
    detected X-rays near Sgr A*, likely given off from this hot gas.
    ---
    Prior research suggests that Sgr A* was also surrounded by
    relatively cool gas, with temperatures ranging from about
    minus 280 degrees F to 17,500 degrees F (minus 170 degrees C
    to 10,000 degrees C). However, it remains uncertain how much
    cool gas surrounded Sgr A*.
