The paper considers the fate of the electrically charged ( Z { e } \approx 10 { e } ) Planckian elementary black holes – daemons – making up the dark matter ( DM ) of the Galactic disk , which , as follows from our measurements , were trapped by the Earth during 4.5 Gyr in an amount of \sim 10 ^ { 24 } .
Due to their huge mass ( \sim 2 \times 10 ^ { -8 } kg ) , these particles settle down to the Earth ’ s center to form a kernel .
Assuming the excess flux of 10 \div 20 TW over the heat flux level produced by known sources , which is quoted by many researchers , to be due to the energy liberated in the outer kernel layers in daemon-stimulated proton decay of iron nuclei , we have come to the conclusion that the Earth ’ s kernel is presently measured in few fractions of meter in size .
The observed mantle flux of ^ { 3 } He ( and the limiting ^ { 3 } He / { } ^ { 4 } He \sim 10 ^ { -4 } ratio itself ) can be provided if at least one ^ { 3 } He ( or ^ { 3 } T ) nucleus is emitted in a daemon-stimulated decay of \sim 10 ^ { 2 } – 10 ^ { 3 } Fe nuclei .
This could remove actually the only objection to the hot origin of the Earth and to its original melting .
The high energy liberation at the center of the Earth drives two-phase two-dimensional convection in its inner core ( IC ) , with rolls oriented along the rotation axis .
This provides an explanation for the numerous features in the IC structure revealed in the recent years ( anisotropy in the seismic wave propagation , the existence of small irregularities , the strong damping of the P and S waves , ambiguities in the measurements of the IC rotation rate etc . ) .
The energy release in the kernel grows continuously as the number of daemons in it increases .
Therefore the global tectonic activity , which had died out after the initial differentiation and cooling off of the Earth was reanimated \sim 2 Gyr ago by the rearrangement and enhancement of convection in the mantle as a result of the increasing outward energy flow .
It is pointed out that as the kernel continues to grow , the tectonic activity will become intensified rather than die out , as this was believed before .
