    Shouldn't there the release of energy in the form of light? Why the darkness?

    They are not really black, just appear that way due to the differences in temperatures from the surrounding areas, from our persepctive 150,000,000 kms away .

    They're not black, they're just silhouetted.

    There is, it's just drowned out by the brightness of the sun behind it.

    Further ;

    The sunspots are as hot as the suns corona.

    And these sunspots do not have an infrared signature at all.

    Because REALITY indicates that this is the case, regardless of your personal feelings.

    Yep.
    Can you see the light of a torch in front of a car's headlights?
    Totally wrong.
    Off the top of my head the core of the Sun exceeds 10 million C: The Photosphere/Surface is around 6,000C, Sunspots around 3,000 C and the corona around 2 million C
    Like I said...are you able to see a torch light in front of a car's head lights?

    Your questions have been answered river, and your "made up claims" refuted for what they are.
