Sunspots appear as dark blotches on the surface of the sun, yet the 
temperatures everywhere in the sun should be great enough to sustain 
incandescence, even in these "cooler" regions... why ( then ) do they appear 
dark ? Is this a perceptual thing ?( = "relatively" dark ) This region of the 
sun should be fairly transparent, no ? How can thse things possibly be dark ?
