Tunguska 2 Averted by a Fraction of a Second


The Tunguska explosion involved a comet/asteroid at least 300 feet wide exploding 3-6 miles above Siberia in 1908. The meteor that detonated above a Russian city earlier today was far, far smaller, and went off at a far higher altitude. So how close did the city of Chelyabinsk come to doom?
Consider this: a ten-meter stony asteroid exploding at the altitude of the Tunguska visitor would pack the same punch as the Fat Man bomb. This rock was much bigger, with a mass of 7000 tons. Had the explosion occurred a fraction of a second later in the meteor's descent, over a populated area like Chelyabinsk, most if not all of the dash cam owners who uploaded to youtube would have been fried, along with much of the town.

40 They explode because of the intense heating when they hit the atmosphere- friction with the air creates this heat


smaller ones will burn up before impacting the surface

bigger ones explode and shower fragments over a large area

really big ones make it all the way to the surface relatively intact , and then you are in a world of shit

50 That NASA link says 7,000 tons, but this morning I was reading 10 tons. I guess I'd have to believe NASA. The videos were incredible. It seems like the shock wave was delayed by at least 20 seconds. Some of the dash cam ones never even heard the boom. Maybe it was delayed by minutes. It's hard to imagine how something can go so fast, that it turns white hot and explodes just from friction.

I don't think I've ever seen such a look of misery and dejection on the face of my daughter as I just did a moment ago.

I sat down with her on the sofa and (as calmly as I could) tried to explain to her why the Republicans lob meteorites at the planet. I tried to keep my voice steady, but it became increasingly difficult - the rage and feelings of helplessness were just too much. She could tell something was wrong. I found myself at such a loss for words - nothing made any sense; nothing makes sense anymore. I finally had to admit, " I just don't know - I don't know what's going on in this country anymore..."

When I finished her lower lip started to tremble and her eyes began to fill with tears, "Mommy" she said, "why are the Republicans doing this to the country?" Well, that was it for me: I finally fell apart. I just fell into her arms and we both began sobbing for several minutes. She had to comfort me and get me back on my feet. Sometimes I just think itís too much, but seeing the strength in my daughters voice helped me to get through.

Second, they had the gulags. Third, that is where they killed the Tsar's family and where they have all those serial killers running lose. Fourth, it's always being flatten by meteorites.

63 The object doesn't explode per se.

You have an object traveling at 40,000 kilometers per hour hitting thicker atmosphere.

What sound does a car make hitting a wall at 60 miles per hour? What happens to the car?

64 NASA is estimating 200 x the blast of Little Boy, which makes it between 280 and 300 KT, or about 2 x the most common warhead in our box of boom...

In technical terms, kinetic energy scales as the square of the velocity and this object was moving like a motherf*cker. Got dump that energy somewhere if the rock doesn't go through the planet and come out the other side at the same velocity.
