“At that moment there was a bang in the sky and a mighty crash… The crash was followed by a noise like stones falling from the sky, or of guns firing.”

–Eyewitness account of the

Tunguska Event – June 1908.



On June 30, 1908, a large explosion tore through the air in the sparsely populated area in Siberia. This large fireball, believed to be 50-100 meters wide, flattened over 2000 square kilometres of forest. To this day, over a hundred years later, scientists are unable to convincingly explain the cause of this explosion, and one of the most plausible theories of an asteroid or comet hitting the earth is also insubstantial, due to there being no traces of any large object in the blast radius. This led to a rise in all sorts of conspiracy theories, from a spaceship crash-landing on the surface, to black holes colliding with the planet or even a collision of anti-matter particles with matter particles. However, a team of Ukrainian scientists put most of the more ridiculous theories to bed by analysing the samples of peat from the area dating back to 1908, and finding tiny fragments of material found in meteorites. The trick then, was to look for small fragments, and not big pieces.
