Craters and Antipodes: Pliocene-Pleistocene (Hiawatha, Eltanin, Sudbury, SIberia)

This is a Google Earth project WIP video tour demonstrating the spatiotemporal invariance of cosmic serpents, magma/volcanic hotspots/etc. The idea is to take the 3 small-circle crater swath-swarms from Shaw's 1993 book "Craters, Cosmos, and Chronicles", find others, take his Meridional Great Keel great-circle based on satellite orbits, find others, and take his ideas on magma and volcano hotspots, and antipodal relationships. I have barely begun adding in the magma and volcano hotspots, and barely started in on the antipodes. I do have ALL the craters (from PASSC and my own), and a handful of the more prominent craters' antipodes. As it stands in this video, I have only been adding a few of the more prominent great-circles, and indeed, just the craters alone are enough to justify them. I have already found several magma/volcano/crater/antipode great-circles despite the lack of completion. Pliocene-Pleistocene Boundary, Ice Age Catalyst 2. Here I cover another possible catalyst/contributor to the Pleistocene Ice Age onset. It once again inlcudes Eltanin, but I decided to try this swath/great-circle after reading about recent dating of Hiawatha as possibly being around 3-2.4mya, similar to the hypothesized Eltanin. We pass by a Siberian Trap domelike feature near the Yenisei River and orilsk Russia, not terribly far from Tunguska.This swath also passes proximal to the Hiawatha antipode in Antarctica, and passes proximal the Sudbury antipode, and almost directly over Sudbury. 1.849Ga and 80mi/130km. Sudbury is one of the oldest post Late Heavy Bombardment astroblemes on Earth, and the 3rd largest. Eltanin is a hypothesized asteroid impact around the time of the Pliocene-Pleistocene boundary as well, just like Hiawatha. Keep in mind the Homo genus seems to sit entirely within the Pleistocene, ie humans of any and all kinds came about precisely because of the changing climate at the end of the warmer Pliocene, which began cooling on the approach to the Pleistocene Ice Age, and the frustatration other organisms must've experienced at that time over 3mya, and the new niche that an ape-like proto-Homo organism began to occupy. The Ledi jaw of Homo habilis of Ethiopia is about 2.8mya, the Pleistocene started around 2.614mya. Perhaps Eltanin and Hiawatha are a part of that frustration building episode that lasted hundreds of thousands to about 2my. The purple dots are a NASA Google Earth simulation of the projected impact areas of a hypothetical comet, as a way to demonstrate the viability of Herbert Shaw's hypothesis. What we are essentially mapping are spin-orbit and orbit-orbit harmonic resonances of the Earth's satellite system. Whether natural or manmade satellites, these are the same paths - and the are all meridional, not equatorial. The Moon is in a tidally locked spin-orbit with the Earth (lunar sidereal month). The more simple a harmonic resonance (whether spin-orbit or orbit-orbit) the more liekly and more stable that orbit will be. The Meridional Great Keel is arguably the most stable satellite orbit. See this image for a clear mental picture of the Earth's satellite meridional great circles: https://l-zone.info/wpcms/wp-content/uploads/2015/08/satmap.jpg As the Earth's terminal natural satellite reservoir fills and empties due to tidal effects of solar system objects (or passing cosmic serpents), they can be ejected out of geocentric orbit, or sent chaotically down to Earth (either airbursting or impacting, typically at 45deg, though imapctors can range from about 40-85 deg, even on down to 15deg. The more shallow the angle of approach, the more likely the atmosphere will force the cosmic serpent back out, or airburst it like Tunguska). The Asteroid Belt (10^2AU), Kuiper Belt (10^3AU) Inner Oort Cloud (10^4AU), and Outer Oort Cloud (10^5) can be perturbed as our solar system makes its 235my revolution about the galactic center (galactic tides), or from perigee to neighboring solar systems. They then get sent our way, shepherded by the outer planets like Jupiter, and the solar system center of mass, adn the sun. The eccentricity and inclination of their orbit in respect to Earth determines if the Earth-Moon system will capture them (due to fuzzy boundaries resonance capture as in Belbruno). Even still, they may not pose a threat for grazing or impact, but just have a geocentric orbit. Fuzzy boundaries and fractal resonances allow for a greater chance into the capture cone/collision cone than most would initially think, but the Moon is our last natural defense. Unfortunately, a passing cosmic serpent can perturb our smaller natural satellites (which are very terminal at this point in the history of the Universe - millions of years ago, a huge reservoir could've easily built up, such as the K/T events 70-35mya).
