Why is the Earths core warm

Hi Elling, You say there is excess heat radiating from the Earth. Do you happen to know how much excess heat flows from the Earth? I know the Earth gets about 250 watts per square meter from the sun but I don't know how much radiates into space from the surface. There is very little data on this detail that I have found. Maybe you know more sources of data.

The Earth's core is warm (liquid?) because shock waves generated by huge, super huge impacts are most concentrated there by so-called "serm" resonance, as explained in my ebook: Horizontal layering of substrata causes etalon (laser) resonance and so on.

Serm resonance has the effect of parallel-ising, vertical-ising the impact-generated shock waves. Hence concentration of shock waves energies, maximal fracture-melt in the core and so on. Hence also heavy metal metalogenesis/mineralisation of mantle material at the CMB, ubiquitous planetary- and smaller scale (shock wave "inscription") interference pattern symmetries, antipodal resonances and so on.

I believe it myself. But nevertheless it is true . . . " Philip K. Dick

The problem with all the theories about why the Earth is hot inside and cold on the surface omit the fact that all objects radiate energy at a rate known to be proportional to blackbody temperature. The Earth radiates much to much energy for it to stay hot for more than a few million years so the people who do models invent stuff to keep reality out of the mix. The model becomes more important than reality because it predicts what will happen so we don't worry about what will happen.

Of course there is always background heating from radio-active decay of a whole lot of elements, uranium, thorium, radio-potassium and so on. Haven't these been shown to account for any excess heat by anybody?!?!?

The amount of heat from all these reactions is assumed to be causing the excess heat but anyone can do the math and see there is a lot of heat not being included in the model. For example, the Earth is a blackbody with an average surface temperature ~295 kelvin(it may be a bit more). A 295k blackbody radiates ~430 watts per square meter. The Earth gets ~250w/m^2 from the sun. So, how do you account for the rest of the radiation? According to the model none of the above is correct and it has its own logic to rationalize the problem so it does not exist.

The obvious explanation is that the Earth is a long way short of being a black body, as most solids are. What we need is a table showing how grey various earth crustal minerals are to all visible and infrared solar radiation.

While we at it, we may as well include various building materials relevant to passive solar heating of homes and so on, which many are interested in. An architect friend was telling me that mud bricks are much better than concrete for soaking up solar radiation.

Obviously what's needed, now that oil is no longer cheap, are "solar coatings", new ways of coating concrete and other building cladding materials to make them blacker or whiter in various ways, blacker one way, whiter the other way and so on.
