Hello. If the sun's core is several hundred million degrees (Fahrenheit), why is it that the surface is only a scant 11,000 degrees? I understand science is still confounded by the atmospheric heat of the sun (again, tens of millions of degrees in the corona), but I've been lead to believe that modern science can answer the surface temperature question. If this is so, what is a reasonable explination for this? To work this out for myself, I pondered why the surface of the earth wasn't warm in light of the apparent heat radiating from the core. To my limited knowledge of how heat, as a radiation of agitated atoms, interacts with non-agitated atoms, it stands to reason that the enegry levels (that we experience as heat_) are absorbed (and disfussed) by the many layers of non-agitated atoms in the rock. This - it seems - reduces the overall heat (as it's now shared between the two parties). The sun, on the otherhand, doesn't seem to have anything to absorb the heat. Is it that the atoms that make up the radiation and conductive layers of the sun are SO vast that the temperature just drops off to 11,000~ degrees by the time it crests to the surface? How deep is the sun, pole to pole? Just curious.. thanks.
