What happened on June 30, 1908 in the Tunguska region of Siberia? It was around 7:15 in the morning when a powerful explosion occurred near the Podkamennaya Tunguska River - some eyewitnesses also claimed to have heard several tremors. The earth shook so much that it could be felt as far away as Europe. The consequences were devastating: in an area the size of the Luxembourg, 60 million trees were snapped, and a fire, a huge shock and an immense pressure wave could be felt 500 kilometers away – that this did not become one of the greatest catastrophes of humanity, is solely because the incident occurred in a sparsely populated area. Experts put the explosive power of the event at 10 to 15 megatons of TNT, which is more than a thousand times greater than that of the Hiroshima “Little Boy” atomic bomb – other scientists assume an even higher value and estimate an explosive power of 50 megatons of TNT. This incident is recorded in history books as the Tunguska catastrophe.
When catastrophe struck a vast area of Siberia on that clear and beautiful June morning in 1908, little attention was paid to it. In the almost unpopulated area, only a few people witnessed this event. People at the time could not have imagined that these explosions would one day be one of the mysteries of the century. To this day, internationally renowned scientists of various disciplines argue about the causes of this disastrous explosion. For decades, the only serious explanation was the theory that a celestial body such as a comet or a meteorite must have triggered this gigantic explosion.
However, since dozens of international research teams have so far been unable to find a crater or any clearly definable metal or rock from space, wild speculation continues to flourish about the true cause. Novels, films and even an opera dedicated to the event sometimes reach the point of absurdity in their explanations and contribute to the fact that numerous legends have grown up around the Tunguska event. Some for more outlandish hypotheses linked the Tunguska event to the crash of an extraterrestrial missile or contact with antimatter – and these are still the most harmless of the explanation attempts. But even within the serious research community there are doubts about the dogma of the meteorite impact.
In particular, the theory put forward by astrophysicist Wolfgang Kundt in Germany that a gas deposit explosion was the trigger is becoming increasingly important for Tunguska research. On the occasion of the 100th anniversary of the Tunguska explosion, the German geologist and geographer Christoph Brenneisen set off on his second expedition to the Siberian taiga. The film follows Brenneisen on his expedition to the impact area. He would like to finally solve the mystery, because to this day there is no crater or other piece of evidence as to the cause. The film also features well-known scientists from Germany, Great Britain, Italy, Russia and the USA.
The film gives an exciting insight into current Tunguska research and presents theories that are both serious and bizarre. “Big Bang in Tunguska” is a scientific documentary full of humor and information, sometimes speculative and full of enthusiasm for crazy theses and theories, sometimes just down-to-earth.

Directed by Christoph Schuch ; A Halbtotal Film GmbH Co-Production with ZDF and 3sat
