Terrestrial origin of SNC meteorites and 30 Myr extinctions' shower source

Strong strengthening of material under high confining pressure and jet nature of outflow from impact craters permit to show meteoroid impacts of >=10E6 Mt TNT equivalent are capable of ejecting rocks up to ~1 km in size from the Earth into space. That permits one to propose the terrestrial origin of some NEA's and SNC meteorites. It is shown the isotopic anomalies of nitrogen, argon and xenon can be related with terrestrial mantle samples. The same applies to the oxygen isotope shifts if one recalls the known manifestations of the kinetic effects of isotopic fractionation.

Hypothesis of a daemon kernel of the Earth

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.

Detection of several daemon populations in Earth-crossing orbits

Detection of negative daemons, DArk Electric Matter Objects, viz. Planckian supermassive (~2*10^-5 g) particles, whose population has been detected in March 2000 to populate near-Earth, almost circular, heliocentric orbits (NEACHOs), is being continued. The NEACHO objects hit the Earth with a velocity ~10-15 km/s. The results of these and new experiments (April-June, 2001) are now processed taking into account the scintillation shape depending on the magnitude and sign of the velocity of the daemons crossing our detector. The data accumulated during the time of the experiment and processed in this way reveal also the presence of (1) a high-velocity (~35-50 km/s) daemon population whose objects can be related to a population in the Galactic disk and/or that in strongly elongated, Earth-crossing heliocentric orbits (SEECHOs), as well as (2) a low-velocity (~3-10 km/s) population in geocentric Earth-surface-crossing orbits (GESCOs), whose objects traverse repeatedly the Earth to suffer a decrease in velocity by ~30-40% in a month in the process. An evolutionary relation between all these three (four?) populations is discussed. Assumptions concerning their manifestations in further observations are put forward. An analysis of possible interaction processes of daemons, which may have different velocities and directions of motion, with the detector components [ZnS(Ag) layers, 0.3-mm thick tinned-iron sheets etc.] on the atomic (emission of Auger electrons) and nuclear (nucleon evaporation from a nucleus excited in the capture and, subsequently, the decay of its protons) levels has permitted estimation of some characteristic times. In particular, the decay time of a daemon-containing proton is ~10^-6 s.

Daemon detection experiment

A month-long observation of two horizontal ZnS(Ag) scintillating screens, 1 m^2 in area and located one above the other a certain distance apart, revealed about 10 correlated signals, whose time shift corresponds to an average velocity of only ~10-15 km/s. We assign the origin of these signals to the negative daemons, i.e. electrically charged Planckian particles, which supposedly form a part of the DM in the Galactic disk and were captured into the near-Earth orbits. The estimated flux of daemons is >=10^-4 m^-2 s^-1. The key part in the detection of daemons is played apparently by two processes: (i) the daemon shedding the captured heavy nucleus in a few tens of mks as a result of a relatively rapid decay of the daemon-containing nucleons, and (ii) emission of numerous Auger electrons and nuclear particles occurring in the next capture or recapture of a (heavier) nucleus by the daemon.

Further daemon detection experiments

The experiments on detection of daemons captured into geocentric orbits, which are based on the postulated fast decay of daemon-containing nuclei, have been continued. By properly varying the experimental parameters, it has become possible to reveal and formulate some relations governing the interaction of daemons with matter. Among them are, for instance, the emission of energetic Auger-type electrons in the capture of an atomic nucleus, the possibility of charge exchange involving the capture of a heavier nucleus etc. The decay time of a daemon-containing proton has been measured to be D τ~ approx 2 mks. The daemon flux at the Earth's surface is f ~ 10^{-7} cm^-2 s^-1. One should point out, on the one hand, the reproducibility of the main results, and on the other, the desirability of building up larger statistics and employing more sophisticated experimental methods to reveal finer details in the daemon interaction with matter.
