Tunguska event may be caused due to an asteroid
Tech Explorist ^ | May 21, 2020 | Amit Malewar

On the morning of 30 June 1908, a large explosion occurred near the Podkamennaya Tunguska River in Yeniseysk Governorate (now Krasnoyarsk Krai), Russia. That event is known as the Tunguska event that leveled trees across more than 2,000 square kilometers.

It is classified as an impact event, even though no impact crater has been found. Due to the remoteness of the site and the limited instrumentation available at the time of the event, modern scientific interpretations of its cause and magnitude have relied chiefly on damage assessments, and geological studies conducted many years after the fact.

The most likely cause is an airburst asteroid strike in which the asteroid explodes in the atmosphere, similar to the Chelyabinsk meteor strike in 2013. Given the size of the impact region, it's estimated that the original asteroid was nearly 70 meters across. This would explain why no large impact crater has been found.

Fragments of Chelyabinsk were discovered soon after the impact. But, in the case of the Tunguska event, there were no fragments. This causes several assumptions on the cause of events such as a massive leak of natural gas, or even the explosion of an alien spacecraft.

A new study shedding light on the event again, suggests that there are no fragments because the asteroid didn't fragment after all. Instead, it glanced off Earth's atmosphere.

I liked the “small black hole impact” theory I read many years ago.

Ancient alien astronaut theorists generally agree that the Tunguska Event was caused by Nicoli Tesla accidentally misdirecting his death-ray.
I have to ask myself if such a thing is possible,..........and the answer is “yes, yes it is”.

It seems to me it should leave a radiation signature - e.g., evidence of a burst of gamma rays.

Eh, who needs evidence when you can just wildly speculate?

True! Evidence spoils the conversation.

I probably posted something in that too. No guarantee that that it really is an impact artifact, but, it is interesting.

I never believed that it was a comet. Not enough damage, imho.

Of interest:

Can’t recall what channel, but back when I had satellite I watched a documentary which preceded the supercomputer simulation, which included firing a high speed projectile into sand in a chamber.

It was that simulation which led to the air burst theory, even matching the butterfly pattern in the laboratory.

I can’t recall if they created airbursts, but it seems likely since I have a memory of a sand floor with little sticks laying out flattened in a butterfly pattern.

It was an excellent demonstration of good science.

Until I looked tonight, I’d never seen the Sandia simulations.

At the risk of sounding like an echo, it was Aliens.

Yeah, I think they misjudged the distance during their warp jump. ;^)

On the possibility of through passage of asteroid bodies across the Earth’s atmosphere
Daniil E Khrennikov, Andrei K Titov, Alexander E Ershov, Vladimir I Pariev, Sergei V Karpov
Monthly Notices of the Royal Astronomical Society, Volume 493, Issue 1, March 2020, Pages 1344–1351, https://doi.org/10.1093/mnras/staa329
Published: 04 February 2020 Article history
https://academic.oup.com/mnras/article/493/1/1344/5722124?login=true
ABSTRACT
We have studied the conditions of through passage of asteroids with diameters 200, 100, and 50 m, consisting of three types of materials – iron, stone, and water ice, across the Earth’s atmosphere with a minimum trajectory altitude in the range 10–15 km. The conditions of this passage with a subsequent exit into outer space with the preservation of a substantial fraction of the initial mass have been found. The results obtained support our idea explaining one of the long-standing problems of astronomy – the Tunguska phenomenon, which has not received reasonable and comprehensive interpretations to date. We argue that the Tunguska event was caused by an iron asteroid body, which passed through the Earth’s atmosphere and continued to the near-solar orbit.
