Platinum group elements are generally regarded as indicative elements of extraterrestrial substances. Elemental analysis is certainly not as good as direct study of the debris, but it can also indirectly analyze the cause of the explosion from the side.
(5) The Tunguska explosion site did not leave any direct evidence for study, and the cause of the explosion could only be inferred by analyzing the elements of the scene. A thousand times more powerful than the Hiroshima bomb that exploded more than thirty years later. (4) Researchers at the Irkutsk earthquake station determined that the strange blast was the e*quivalent of 10 to 15 million tons of TNT. White nights have continued to appear in large areas of the northern hemisphere, and people as far away as Western Europe can read newspapers at night without lights. For a few days after the explosion, the sky over 9, 000 miles of Tunguska was shrouded in a ghosted orange color, a giant fire ball that stretched from the Lena river in the east to Ireland in the west and Tashkent and Bordeaux in the south. (3) Tunguska is surrounded by dust and smoke, clouds of fire and hot waves of gas that sweep across the vast taiga forest, where fires burn for days and herds of reindeer burn to ashes. Three powerful explosions were then felt.
More than a minute later, people heard many times from the distance, clear roar, the earth began to tremble. (2) An explosion like a cannon was heard, and a burning monster, with a long firework tail, swept across the sky from south to north and disappeared beyond the horizon. After fifty or sixty unusual sounds, the sound gradually subsided, followed by a short but regular pause. The wind stopped suddenly, and after a moment of silence there was an extraordinary noise from below, first like a train rolling along the track, then like a cannon five or six minutes later. Outside, the gray black sky suddenly wind, the wind mixed with a huge noise. (1) At dawn on June 30, 1908, among the sleeping Russians in the Tunguska region of Siberia, there were couples hugging, sleeping children, and elderly people talking in their sleep. Here are the top 10 Mysterious Facts about Tunguska Explosion Although the theory has the most support, the impact crater has not been found, leaving the Tunguska event a big mystery. Most experts have argued that the Tunguska event should have been a massive meteorite, comet or asteroid that hit the earth. These were truly remarkable phenomena if for no other reason than for the difficulties encountered in merely describing them.Tunguska Explosion is one of the most mysterious and widely studied phenomena of the past century. While the merits of the different candidates were compared, we were amazed to realize that neither the phenomena of the very small nor those of the very large could compete with the phenomena of the very cold. We thought the best way of deciding which phenomena to choose was to rely on our intuitive notion about the "degrees of peculiarity" developed, no doubt, during the past ten years of active research in theoretical atomic and elementary particle physics. A few years ago we set ourselves the task of carrying out a methodological study of the "most peculiar" phenomena in physics and trying to understand the process by which an observed (rather than predicted) new phenomenon gets "translated" into a physical problem. Being the only macroscopic quantum phenomena they also manifest a sudden and dramatic change even in those properties which have been amply used within the classical framework and which were thought to be fully understood after the advent of quantum theory. Superconductivity (the disappearance of electrical resistance) and superfluidity (the total absence of viscosity in liquid helium) are not merely peculiar in their own right.
This book is primarily about the methodological questions involved in attempts to understand two of the most peculiar phenomena in physics, both occurring at the lowest of temperatures.
