Scientists dig deep to reveal Earth’s hidden layer

I wonder if the two cooling events were pre-collision and post-collision?--Lee:

[Barry Warmkessel]

Usually, comet or asteroid collisions with Earth inject dust into the atmosphere which blocks the sunlight from keeping the Earth warm, but I am not sure that this is what is being considered here.  Instead, this may be the basic formation of the Earth itself.  If that is the case, The ASTRO-METRIC concept may be in play.   Here is some other links related to this subject. Hope I am not wasting your time.

THE ASTRO-METRICS CONCEPT

This concept can be very briefly summarized by the assumption that stars, planets and their satellites (moons)are seeded by primordial black holes (PBHs) These radiate, and as they grow smaller, they grow hotter. Thus, the earth should theoretically be (slowly) heating and expanding.

• EARTH'S CORE FAR HOTTER THAN THOUGHT - 26 April 2013
  New measurements suggest the Earth's inner core is far hotter than prior experiments suggested, putting it at 6,000C - as hot as the Sun's surface.
• HYPOTHESIS OF A DAEMON KERNEL OF THE EARTH - Dec. 23, 2001
  The paper considers the fate of the electrically charged (Ze~10e) 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 ~10^24. Due to their huge mass (~2x10^(- 8)kg), these particles settle down to the Earth's center to form a kernel. Assuming the excess flux of 10-20 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 3He (and the limiting 3He/4He ~ 10^(-4) ratio itself) can be provided if at least one 3He(or 3T) nucleus is emitted in a daemon-stimulated decay of ~100-1000 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. 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 ~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. Hypothesis of a daemon kernel of the Earth.

• HYPOTHESIS OF A DAEMON KERNEL OF THE EARTH
  2 Nov 2001 by E.M. Drobyshevski
  The main ideas of the work were presented at the International Conference "AstroKazan--2001" (24-28 September, 2001, Kazan, Russia) The paper considers the fate of the electrically charged (Ze~10e) 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 ~10²⁴. Due to their huge mass (~2x10^(-8)kg), these particles settle down to the Earth's center to form a kernel. Assuming the excess flux of 10-20 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 3He (and the limiting 3He/4He ~ 10^(-4) ratio itself) can be provided if at least one 3He(or 3T) nucleus is emitted in a daemon-stimulated decay of ~100-1000 Fe nuclei. This could remove actually the only objection to the hot origin of the Earth and to its original melting.
