The Tunguska Mystery (Astronomers’ Universe) 2009th Edition by Vladimir Rubtsov (PDF)

Description

The purpose of the book is a dual one: to detail the nature and results of Tunguska investigations in the former USSR and present-day CIS, and to destroy two long-standing myths still held in the West. The first concerns alleged “final solutions” that have ostensibly been found in Russia or elsewhere. The second concerns the mistaken belief that there has been little or no progress in understanding the nature of the Tunguska phenomenon. All this is treated by the author in a scholarly and responsible manner. Although the book does present certain unusual findings of Russian and Ukrainian scholars, it is important to stress that this is not a sensational book; it is, rather, a serious exposition of the results of rational investigations into a difficult scientific problem. We are demonstrating the true complexity of the problem that is now entering its second century of existence. Simple meteoritic models cannot explain all the characteristics of this complicated event, and therefore certain so-called “unconventional hypotheses” about the nature of the Tunguska explosion are to be considered as well.

⭐On June 30, 1908, on a sunny Siberian morning at 00 H 14 M GMT (7:14 am local time) something exploded in the skies over the Podkamennaya (Lower Stony) Tunguska River in what is now Krasnoyarsk Krai of Russia. The blast blew out windows 200 km away and was heard more than 800 km from the site. The seismic wave was recorded as far away as Germany and the atmospheric pressure wave was measured on barographs in London. The nearest eyewitnesses (30 km to the south-southeast) had their shelter blown away, their local area set afire, and reported a second sun in the sky. Approximately 2100 sq km of forest was radially flattened and then burned. At the epicentre, trees remained standing but were stripped of branches – burnt telegraph poles. The blast occurred at some 6 to 8 km altitude. There is no impact crater.I became fascinated by the Tunguska Event nearly half a century ago, reading about it in ‘Boy’s Life’ or some such and I am not alone, as it has become an enduring Global mystery, familiar to hundreds of millions, and a staple of popular western culture seeking the undefinable. A true X-File. This morning, (26 October 2009) a Google search on ‘Tunguska event’ turned up over 59,000 hits. Not surprising for an occurrence that has been the focus of intense curiosity, speculation and (as Dr. Rubtsov has detailed) an extraordinary investigative effort by Soviet and Russian scientists over the last hundred years.Dr. Rubtsov’s book is an encyclopedic compilation and a well written precis of the scientific records of that marvellous research. From the 1921 Kulik expedition searching for evidence of a meteorite impact (which was not found) to the Centenary conferences held in 2008 to discuss the event (there were more than half a dozen of them), Dr. Rubtsov has catalogued the incredible effort put into the problem over the last century, both by independent researchers and also by the official Soviet (later Russian) Scientific Academies. Much of the content and references have not been widely documented in the West prior to this publication and that is not surprising, since most of the citations refer to previous documentation only available in Russian. It is an excellent reference book and a worthy addition to the libraries of all anomalists.More than that, it is clear from Dr. Rubtsov’s writing that he holds a huge ‘affection’ (for lack of a better word), not only for the still unsolved mystery of the Tunguska Event (which he has been personally involved in for nearly four decades), but also for the vast army of scientific researchers (it was a revelation to me just how vast this army was) who have spent large proportions of their professional lives in trying to make sense of this extraordinary happening. He writes with humour and a subtle wit. The subtlety is not misplaced, since during the Soviet era, subtlety was necessary in addressing the problem. The wrong inference published by an open-minded scientist could have earned him a one way ticket to Siberia and a lifetime spent contemplating the mystery from some nearby Gulag. In this respect, Dr. Rubtsov’s book should be of interest not only to anomalists, but also to historians and others interested in the evolution of the Soviet scientific effort under the paradigm of an (arguably) paranoid totalitarian government.Dr. Rubtsov is meticulous in detailing the evidence that has emerged of the mystery. Unusual celestial phenomena recorded as remotely as Western Europe beginning three days or earlier before the event. Many hundreds of eyewitness reports from up to 1000 km away of a flying object (or objects) as it (or they) approached Tunguska, records of the hemispheric magnetic storm associated with the explosion, analysis of the felled trees, including blast patterns and ‘flash burns’, remnant traces of ‘hard’ or ionizing radiation in the area, the presence of rare earth elements (and other interesting elements) in the zone affected by the explosion, biological mutations and last but not least, barographic records of the explosion that indicate the possibility that it may have had a nuclear origin. The calculated magnitude of the blast itself was 50 megatons, approximately equivalent to the largest hydrogen bomb ever detonated (the so-called Tsar Bomb fired in 1961 in Novaya Zemlya). This was not your garden variety meteorite!The book is extremely well referenced and I suspect that Dr. Rubtsov’s editor, Edward Ashpole, has had a large influence in setting it in it’s final form for English publication. I would have liked a more comprehensive index dealing more specifically with subjects as well as with people – perhaps that will come in later printings?It is apparent that in addition to being a good writer and scientist, above all Dr. Rubtsov is an empiricist. He repeatedly makes the point that there is no use in proposing explanations that do not fit all of the empirical data. From Kulik’s 1921 meteorite, through comet cores, cosmic snowflakes, mini-black holes, an antimatter asteroid and even the ‘fanciful’ explanation proposed by the Russian Science Fiction writer Alexander Kazantsev in 1945 (a distressed alien starship), Dr. Rubtsov has looked at them all. None of them totally fit the data, although some of them have definitely provided insight and guidance for future research.Does Dr. Rubtsov have his own theory? Indeed he does, but I will not reveal it in this review, partly because I am still trying to get my head around it. Does it fit the data? Well, yes. That should be enough although it probably won’t be. There is clearly more work to be done.Heartily recommended for all of us who do not totally trust or accept the current world view promulgated in the popular media. Heartily recommended for all those who like to look at the evidence (the two – ie the current world view and the evidence – are not, in my opinion, necessarily contiguous). I think that Dr. Rubtsov would probably agree.

⭐I had heard of the “Tunguska Meteorite” numerous times via magazines, books, and TV documentaries. It turns out much of that information lies somewhere between unintentionally misleading and flat out wrong. In reality the Tunguska event, which has been researched by top Russian scientists for decades, is still unexplained. Much of this research has been presented in scientific journals, and largely in Russian, leaving many of us in the English speaking west to what we are told by occasional media headlines and poorly researched documentaries. The truth is in fact much stranger and more difficult to resolve than a simple meteorite landing.The author does a fantastic job of walking us through decades of discovery and research. It’s fascinating to watch, almost independently of Tunguska itself, how the scientific world changed around the unyielding enigma of the incident. From the early days of horseback travel and world wars, right up to the present day of computer technology and theoretical physics, researchers have been studying the Taiga looking for answers. It went from the personal quest of one or two scientists to a major multidisciplinary effort of volunteer specialists.The author does not force any one “correct” solution or approach to the problem so much as he documents the approaches and attitudes of others, along with their results. He clearly has a higher understanding of much of the science involved (he has worked on the problem himself), but at no point does he lose the layman reader in complexities. He is a champion of good, honest, procedural science throughout. It’s almost maddening how inconclusive the data turns out to be, but in truth, there is no other way to present it. I fully understand how so many great minds can become obsessed with finding the solution.I would highly recommend this book to anyone of scientific curiosity. It’s an absolutely fascinating natural mystery in and of itself, which may just leave you wanting to book a flight to Siberia to continue the investigation. Beyond that, it’s a wonderful study of a major scientific community evolving and working together (and occasionally, in opposition).Thank you to the author for opening up and documenting this great mystery for major new populations of the world.

⭐This is, simply put, a great book. It delves into one of the great mysteries of the 20th century.There are those of us who, for decades, have been heard or read about the strange explosion in Siberia in 1908 and what might have caused it. Theories abound. Those of us living in the west might have formed the notion that the mystery is solved. Well it’s not. If you never read another book about the Tunguska event, you MUST read this one.In my opinion this is, far and away, the best book I’ve encountered that explains how science actually operates. The author has taken considerable effort to explain the information gleaned from 80 years of research on the event at Tunguska and he carefully and with considerable skill lays out the information in a way that any lay person will understand. By the time you finish this book you will have been exposed to the “hard data” that has been acquired by numerous scientific expeditions to the site, you will understand the various theories that have been proposed and the strengths and weaknesses of those theories. Most importantly this is NOT a book about the authors pet theory; enough of those have been written. He deals with the data honestly and allows the reader to make up his own mind about any possible “final answers”.This book puts real science in the hands of lay people. Once the reader has both a good understanding of the scale of this event (for example, the explosion was the equivalent to 3000 of the Hiroshima fission devices) and some appreciation for the scientific evidence discovered at the site, he will likely come away with an understanding of what makes this event puzzling and awe inspiring.

⭐I have read a couple of western books on this subject that I thought were good, but this is the real deal. I too like you? Thought it to be a stony asteroid, icy bit of comet or somewhere in between, depending on the fashion, with a few loose ends that have surely be solved by now . This book shows you why your wrong? That it simply can not be like what the usual references say. It shows this event to be , with present evidence and knowledge, a riddle, wrapped in a mystery, inside an enigma. How blatant evidence discounts the usual explanations. Presenting you with evidence you can work out why yourself, some written but not referenced by the author until much later. He never lets the subject become tedious and gives just enough background to the main players in history. Also in the book is the incredible tale of how some of these players refused to be cowed for their beliefs about the event even when some mighty figures in the Russian sciences wanted to have nice cosy explanations to it all, perhaps the Russian sciences were more open than the west in the days of the USSR? Great book, could not stop reading it and kept me off the tube and gaming too! 5 stars for that alone but pity I cant give 6!

⭐This book gives a fascinating account of the development of fact-finding andformulation of hypotheses concerning the Tunguska phenomenon. This is a subject,which has had my attention for many years, but this book is by far the besttreatise on the subject which I have come across. The author does an excellentjob in explaining the complicated subject matter in an easily understandable way.Moreover, a gallery of interesting personalities is presented, starting with LeonidKulik who initiated the scientific expeditions in the 1920s.An intellectual adventure – highly recommended.

⭐Much the best and most coherent survey of the Tungus event of those easily available. Thorough and clear, logical and well expressed.

⭐This book is extremely well written and gives a fascinating history of the Tunguska Mystery.I would highly recommend it if you are interested in such subjects.

⭐Repleto de datos técnicos, hipótesis alternativas fundamentadas. Escrito por uno de los mejores físicos que ha estudiado el fenómeno, desmonta las hipótesis convencionales de un asteroide o cometa, que no explican las perturbaciones geomagnéticas inmediatamente posteriores a la explosión, así como otros enigmas que tienen difícil cabida en una hipótesis convencional.
