The Milankovitch theory of influence of Earth’s orbital motion to its climate (Milankovic, 1998), developed during his World War I internment, gives us a brilliant example for deduction of physical laws from nature.
According this theory, all processes (eccentricity, axial tilt and precession) which cause changes of position of Earth’s elf rotation axis relative to the Sun cause ice ages on Earth with ca. 24 000, 41 000 and 100 000 year periods.
As a proposed mechanism of such influence Milankovitch chose the differences of insulation. Calculations show, however, that the real differences in insulation are not so great. Only the research of deep- ocean cores confirmed the theory in 1976 (Hays et al), at the same time rising the question about a mechanism of that connection.
By our opinion, this astronomical climate theory is easily understandable, assuming interaction of new physics, connected with rotation axis of the Earth and the Sun. As analogy we can mention here, that investigations of magnetic storms have shown (Yoshida, 2009), that important for this event is component of the solar wind velocity perpendicular to the dipole axis of the geomagnetic field (we doubt, that influence of the weak Earth’s magnetic field can really cause storms and magnetic storms and trigger earthquakes in months around equinox points (cf. “Richter’s law” in Lomnitz, 1994) .
If we assume, that the self-rotating liquid mass-generated field is emanated more from the Earth’s (and Sun’s) equatorial part, then decreasing of Earth’s axial tilt should cause overheating of Earth (first- its equatorial part). ( We can refer here to El-Nino, which comes at summer solstice (Southern hemisphere).
On the course of decreasing of Earth’s axial tilt polar ice caps will melt, large oceanic streams will stop, and an ice age will begin (The author has been told, that this was the scenario from last ice age).
Within our conception, we can try to explain, why the influence from 100 000 year glaciation cycle, which is caused by eccentricity of Earth’s orbit is the greatest. Precession and changes in axial tilt does not change amount of RLF, which comes to the Earth from the Sun. If the eccentricity of Earth’s orbit (currently 0,017) can rise till 0,058, this can significantly reduce the flow of RLF (or Prana) given that self rotation axle of the Sun is inclined by some 7 degrees relative to Earth’s orbital plane.
In our opinion, explanation of changes of eccentricity of Earth’s orbit with time as caused by gravity of planets is not serious. Elementary calculation shows, that, for example, Jupiter from nearest distance (4.2 AU) attracts the Earth only with 0,005% relative to attraction of the Sun.
Thus, the reduction of inclination of self rotation axis of the Sun relative to ecliptic should be considered as the cause for the 100 000 year glaciation cycle.
In connection to this interesting is the ancient Indian doctrine of Yugas – periods of thousands of years, used for era characterization. Pyramids served as instruments for following the cycles- say, watching the path of shadow of pyramid in spring equinox. (http://www.lost-civilizations.net/mayan-astronomy.html).
Thousand year cycles probably are connected not only to ice ages, but more dangerous processes).
We are thankful for Mr. Peteris Luckans for information and discussion about this topic.
P.S. Dear readers! Thank You for interest in topic. But- seems, that Milankovitch cycles are not causing current Earth’s disaster trend.
