The most mysterious event in human history, which is now 113 years old, but scientists still do not know how it happened.
This was on June 30, 1908, when residents of the Siberian region of Aonki reported the movement of blue light in the sky, which they said was as fast as the sun.
Ten minutes after the light report, a thunderous sound was heard as if heavy artillery was shelling.
The sound was traveling from east to north when a shock wave shook the town and shattered windows.
The epicenter was reported below the ground, however; no tsunami alert was issued. The epicenter was reported below the ground, however; no tsunami alert was issued. The epicenter was reported below the ground, however; no tsunami alert was issued.
For several days after the eruption, glows were seen in the skies over Asia and Europe as a result of ice particles forming at high altitudes, while changes in atmospheric pressure were observed in various countries.
Although no one saw the blast, its location was discovered in eastern Siberia.
The 800 square miles of forest or 80 million trees have completely disappeared and no reason has been understood.
Scientists initially believed it was the result of an explosion, but no crater was ever discovered at the site.
But as large as the forest was completely spotted, it was estimated that the force of the blast was 10 to 15 tons.
Scientists tried to find out why the explosion happened because such a powerful explosion could destroy a large city.
But it has never happened since, and ever since then scientists have been puzzled as to why and what caused it.
Fortunately, the area was uninhabited, otherwise many lives would have been lost, but the heat of the blast was felt by residents of remote towns.
An eyewitness said, "The sky was divided into two parts and the northern part of the sky above the forest seemed to be full of fire."
"At that moment, there was an explosion in the sky and a huge crash, a crash that sounded like rocks were falling from the sky or guns were being fired," he said.
Named the Tongoska Event, it is also the most powerful recorded explosion in human history to date, 185 times more than the atomic bomb dropped on Hiroshima.
But more than a century later, researchers still have questions about what happened.
Some scientists believe that an asteroid was the cause of the explosion, but evidence of such a large space body has not yet been discovered.
Some quarters believe it was a volcanic eruption or a mining accident, but no evidence has been found.
In fact, the climate in this part of Serbia is dramatic, with long winters and short summers, which have led to surface changes that have made the area uninhabitable It's difficult.
No one was allowed to go in for the investigation when the blast occurred, as Russian officials had various concerns.
In 1927, a Russian investigative team finally visited the site and discovered that the damage had been the same for almost 20 years after the explosion.
The team speculated that a spacecraft had exploded in the air, causing damage but no craters or space particles could be discovered.
So the team explained that the swampy area was so soft that it did not suffer any damage while all the debris was buried inside.
But nothing was discovered in the depths of the swamp, and decades later Russian scientists said it was not a meteor but a comet, much of which is based on ice, not rock.
After the catastrophe on the earth's surface, the ice evaporated, but this idea did not prove to be true.
Then strange ideas came to mind as if the ace craft of a space creature crashed at this place.
In 1958, researchers discovered tiny particles of silicate and magnetic rock from the site, and further research showed that the surface had a high amount of nickel, a well-known element of meteorites.
But the debate did not stop, and a 1973 investigation suggested that a black hole had collided with the ground as a result of the explosion, but a rebuttal probe was immediately launched.
In 2014, a team of Ukrainian experts analyzed rock samples collected in 1978 from the site of the explosion and discovered a 1908 layer.
Experts have discovered traces of the carbon mineral lonsdaleite, which is formed when a meteorite hits the ground.
But even that was not a clear result, and a study in 2020 suggested that a large iron meteor came close enough to the Earth to produce a huge shock wave, but passed by the Earth without breaking, and the shock wave The effect was seen in this region.
So this is one of the most mysterious events in human history that is still being researched and more ideas will come to light in the coming years.
