The shift of the Earth's axis
If the Earth was a perfect sphere it could not maintain rotation around an axis. It would behave like a ball: always ready to vary the axis of rotation.
Luckily for us, the Earth is slightly flattened at the poles, and this makes it similar to a gyroscope that rotates around a fixed axis. All this stability would be very beautiful and reassuring but the difference between the diameter of the Earth at the poles and the diameter of the Earth at the equator is only 44 kilometers (12,712 kilometers the smallest and 12,756 the largest), a minimal difference which makes the Earth a highly unstable gyroscope. Do you have a bicycle? Consider a stationary bicycle, placed in its normal position and leave it free: it will certainly fall. Now consider the same bicycle with a person pedaling on it.
What has changed?
Apparently nothing except that in the second case the wheels are in motion. The wheels of the bicycle are bodies moving around an axis and are therefore comparable to a gyroscope. Remove a wheel from the bicycle, the front one is simpler, and hold it with both hands by the hub (the central axis where the spokes meet), now try to tilt the wheel by moving one hand higher than the other and you will see that you will have no problems carrying out the operation. Still holding the wheel by the hub, turn it and try to tilt it again as you did before: it will be much harder if not impossible. According to the physical law of gyroscopes, the larger the wheel, i.e. the further the mass is from the axis, and the faster it rotates, the more stable the wheel, or the gyroscope, if you prefer, will be in its movement.
Applying the principle of the bicycle wheel to our planet we deduce that the Earth is a very unstable gyroscope which only needs a small external force to be disturbed and change its axis of rotation, causing enormous catastrophes.
When a gyroscope is hit by a body which causes it to change its axis of rotation, it reacts with a characteristic cone-shaped movement of its axis called precessory movement, or precession. This movement tends to bring the axis back to its original position.
Flavio Barbiero, admiral and gyroscope expert for NATO (gyroscopes are used to pilot torpedoes) has calculated that the impact of an astral body with a diameter of five hundred to seven hundred meters is enough to move the earth's axis by about twenty degrees. If the Earth was a rigid mass, the preceding movement of the axis would bring it back to its initial position. There would be destruction but the axis of rotation would remain unchanged. Our planet, however, is made up of a very thin hard crust on the outside (about 15 – 20 kilometers thick), and an enormous fluid mass on the inside. This sort of hot jam, once the position of the axis has been varied, tends to maintain the new axis of rotation that has occurred, neutralizing the effect of the gyroscope returning to the previous position.
In the case of an impact with an asteroid of the reported size or larger, in addition to the destructive effect of the impact itself, there would therefore also be a shift of the Earth's axis. Due to the movement, several points of the earth's crust would have ruptured. The boiling jam would tend to escape from the cracks in the very thin cold crust, causing earthquakes and eruptions. If we add to this the formation of enormous waves capable of sweeping the emerged lands, the picture is certainly apocalyptic. The meteorology would be immediately upset and there could be months of rain and drying up of once fertile areas.
Every year around 12,000 celestial bodies with a maximum diameter of about one meter fall to the earth, but thousands of bodies with unstable orbits rotate around the Earth, some of which have a diameter of over 2,000 meters. There is no question that the Earth is a target, that it has been hitted by many asteroids in the past, and the hundreds of impact craters on its surface demonstrate this. Several ancient texts tell us about great catastrophes that occurred in the past: the biblical flood, the epic of Gilgamesh, the destruction of Atlantis are but the most famous. In all these texts there is talk of enormous waves that submerge the inhabited earth, of enormous variations in the climate; It is possible that in many different and distant parts the same things are talked about, almost with the same words, and is all this just the fruit of some author's imagination? Isn't it possible that these texts tell us about real events that changed the course of the history of the Earth and man?
The Earth rotates around an axis inclined about twenty-three and a half degrees with respect to the plane of revolution around the sun, the plane of the ecliptic. The rotation axis, in addition to being inclined, rotates with a conical movement, the precessory movement, just as the axis of a gyroscope would do after something made it deviate from its primitive axis. Due to the inclination on the ecliptic plane we have the seasons, the different duration of day and night, the six months of light and darkness beyond the polar circles.
All ancient cultures tell us about a time when there was eternal spring on Earth. What would the Earth have to be like to have eternal spring ? Simply with the axis perpendicular to the ecliptic plane. In these conditions there would not have been the possibility of having different lighting, and therefore different heating, in the various areas of the Earth and meteorology would have been much simpler and more stable.
The melting of the ice that covered Canada up to twelve thousand years ago has caused the enormous accumulation of lakes and rivers that characterizes it. There is only one other area on Earth where the same hydrogeological conditions from melting ice exist: the small islands of Macquarie and Heard, exactly at the antipodes of Canada! The only explanation I have found for this is that twelve thousand years ago the Earth's axis was not in its current position but moved by about twenty-three degrees (same value as the inclination on the ecliptic plane) so as to pass over Greenland and on Greater Antarctica. In these conditions all of Siberia would have been free from ice and with a temperate climate capable of allowing the life of men and animals.
The mammoth is the extinct prehistoric animal of which we have the best knowledge simply because for three centuries we have found dozens of them completely frozen, suddenly dead with grass still between their teeth. We find some alone, others we find them piled up and stuck between the branches and trunks of trees torn from the ground as if an enormous hand had made balls of animals and plants. Only a major cataclysm such as the shift of the earth's axis could have caused this.
If we consider the maps of the last glaciation, which coincidentally also ended twelve thousand years ago, we see that what we consider as an glaciation was in fact nothing more than a climatic situation different from the current one with Siberia not covered by ice and the frost crust which covered the British Isles except the south of England. Strangely, the same ice situation is also found in several medieval maps drawn with a precision that is difficult to attribute to the cartographers of the time.
