periodicity of Ice Ages compared to mass-extinctions
If my theory that mass extinctions are directly related to one main
proponent-- decrease in Solar Radiation due to the swallowing of the Sun of astro bodies on a periodic bases, is true in part or whole would also imply that the periodicity of the Ice Ages is most likely a result of the swallowing of a stream set of comets or asteroids or OortCloud objects. Below I list 2 different websites, one showing a periodicity for Mass Extinctions and the other showing a periodicity for the Ice Ages in the Pleistocene. If my theory is correct would suggest that the both the Mass Extinctions and Ice Ages have something in common. That the Sun radiation was lowered on a periodicity because of swallowing up of comets, asteroids, OortCloud objects and even moons and planets. Do comets or meteors have orbits that matches the periodicity of the Ice Ages? If the conventional wisdom for the cause of the Ice Ages as a migration of the tilt of the axis by Earth is true, then the Ice Ages should be a normal phenomenon going back to the earliest beginnings of Earth. And that there should be about 4 Ice Ages per every 2 million years stretching back as far as 4 billion years. But if the Ice Ages were caused by the Sun swallowing up comet streams or OortCloud objects then the Pleistocene Ice Ages are a unique and rare event. I have a question here? Do geologists know of any meteors that struck Earth and have a pattern that matches the 4 glacial periods versus the interglacial periods. You see, if Sun Swallowing is the cause of the Ice Ages then some of the comets or meteors swallowed by the Sun by happenstance collided with Earth as Earth got into the way but was really destined for the Sun. So my question is really whether any meteors or comets of a large type were found in the Interglacial periods of the Pleistocene. If I am really lucky, then there should be found say about 4 large meteor strikes on Earth, one for each Interglacial period. If memory serves me correctly, that Germany has a city built on the center of a meteor impact site. I do not recall if it is dated to the Interglacial time period. A few days ago I posted a periodicity of about 26 million years as listed in this website: http://lilt.ics.hawaii.edu/belvedere...ons/Period.htm Sepkoksi said, "I'm stuck for a mechanism for causing such a period. We are aware of no documented process with a cycling time of approximately 26 million years." Period Million Years b.p. % Extinction 36 16 end-Cretaceous 66 46 82 23 120 16 end-Jurassic 144 20 160 20 190 23 end-Triassic 213 44 end-Permian 248 60+ Percent of genera of marine animals that became extinct at various times. (From Raup and Sepkoski, 1984; and Fox, 1987). http://lilt.ics.hawaii.edu/belvedere...ons/Period.htm The best I could find for the periodicity of Ice Ages is not that good: quoting http://www.geevor.com/education/cd/t...meline_05.html The Pleistocene Ice Ages Time Event 2,000,000 Ludhamian Ice Age Stage, temperate climate, Pleistocene onset of climatic deterioration. 1,900,000 Thurnian Ice Age Stage, cold climate, tundra vegetation. 740,000 Pastonian, temperate climate. Timezone names here and below are divisions of the British European Ice Ages. 700,000 Beestonian, cold climate, permafrost known. 660,000 Cromerian, temperate climate, Tertiary relict plants. Birch, pine and spruce vegetation. Bison, horse, rhinoceros, hippopotamus, mammoth. 350,000 Anglian, glacial. Evidence of man in Kent's Cavern, Torquay. Grass and sedge vegetation. 250,000 Hoxnian, interglacial, warm. Birch, pine, oak and alder vegetation. Hippopotamus, rhinoceros, cave bear, cave lion. In Britain there is the Clactonian tool producing flint industry. 200,000 Wolstonian, glacial. Ice floes in English Channel? Grass and sedge vegetation, Woolly rhinoceros, wolf, reindeer, cave lion. 125,000 Ipswichian, interglacial, warm. Formation of the 25 foot (eight metre) raised beach deposits prevalent along many coasts. This is distinguished from angular periglacial head (the product of permafrost freeze-thaw erosion) mainly by the rounded boulders. Both types can be clearly seen just south of Cape Cornwall at Porth Nanven Birch and pine vegetation. Hippopotamus, hyena, bison, auroch (large ox) red deer, cave lion. 72,000 Early Devensian Glacial, cold. Sub-arctic tundra. Mammoth, woolly rhinoceros, reindeer, musk ox, horse, lemming at various times throughout the period of Devensian glaciations 61,000 Chelford Interstadial, temperate to cold. Coniferous forest. Lower Palaeolithic. 56,000 Middle Devensian Glacial, cold. Sub-arctic tundra. 42,000 Upton Warren Interstadial. Temperate climate, open grassy plains Middle Palaeolithic. http://www.geevor.com/education/cd/t...meline_05.html Archimedes Plutonium whole entire Universe is just one big atom where dots of the electron-dot-cloud are galaxies |

periodicity of Ice Ages compared to mass-extinctions - troll alert!
"Archimedes Plutonium" wrote in message om... Why do you persist with this tripe, when no one is even close to buying this hogwash. We've told you repeatedly that your theory has no probability of validity whatsoever for reasons that have been stated repeatedly. So give it up, and stop posting irrelevent bull**** on this newgroup. You can't rewrite the geological record no matter how hard you try. |

periodicity of Ice Ages compared to mass-extinctions
There is a group of meteor showers every year at a regular time. If memory
serves they are called the Leonid and/or Persis meteor shower. Now I wonder if at one time in the past they were actually more larger such as the Asteroid belt and that they regularly had asteroids of a large size and that they were regularly swallowed by the Sun and especially during the Pleistocene Ice Age and the direct cause of those 4 patterns of Ice Ages in the Pleistocene.

They travel in the same orbit as the comet. The Persiad meteor shower are small particles left behind by the Swift-Tuttle comet. You really should get an education before you post such idiotic nonsense. |
