Hypotheses of glaciation #001

There are a lot of hypotheses explaining glaciations by terrestrial causes. Some of them are complicated and require lengthy explanations. Such hypotheses will have to be retold in a simplified way. In Cuvier's time, the idea of the gradual cooling of our planet prevailed. It was developed by the famous naturalist Buffon. He even studied the cooling rate of cast iron cores in order to estimate how long the globe could cool down (given its huge diameter). The results turned out to be very dubious: after all, the temperature of the earth's depths has not yet been precisely determined. A comparison of the globe with a cast—iron core is permissible only from the standpoint of geometry: the similarity of the appearance of two figures is all. The cast—iron ball is in the Earth's atmosphere, and the planet is in space. There are completely different forces at work in the ball and on the planet. For example, even at a depth of several tens of kilometers (the thinnest shell of the Earth, with a radius exceeding six thousand kilometers), any of the most durable substances change their properties unrecognizably under gigantic underground pressure. If the Earth cools down gradually, it should eventually lead to great cold and glaciation. Unfortunately, such a simple and convincing hypothesis is just as simply and convincingly refuted. Most importantly, glaciations accompany the entire geological history of the Earth. Traces of them are observed in sediments dating back a billion years. After a very large glaciation, the Carboniferous-Permian (two hundred and fifty million years ago), almost the entire surface of the planet was warm. And even earlier, there were glaciations. But this does not mean that the Earth was formed necessarily in a "cold way", with the accumulation of cosmic dust or meteorites. In recent years, many well-known astronomers (among them Academician V. A. Ambartsumyan) have written about the possible formation of the Sun and planets as a result of explosions of galactic nuclei. Cosmic explosions of inconceivable power have been observed many times by astronomers. Space develops not only slowly and regularly, but also catastrophically, with explosions giving birth to new stars and, possibly, planets. But even if the Earth was once a red-hot droplet of solar matter, it should have cooled down thoroughly during the first one to two billion years of its cosmic history (the geological history of the Earth begins with the formation of the first sedimentary rocks on it - two to three billion years ago). If some cooling of the Earth continued, then it happened more slowly and finally stopped. Thousands of times more energy comes from the Sun to the surface of our planet than from the deep bowels.
