Well, that is somewhat of a distorted way of putting it, but what's really scary is that you're almost fanatic about not letting the slightest possibility it might be something different than what it looks like at first sight.
The fact you believe it can even be a possibility is ludicrous. [...] And then you say the movies would be part of the conspiracy ? Laughable.
What I've said is that all you have is "some videos" on youtube. They may be fake (or edited, or whatever), or they may be "genuine" insofar as they're something people really saw on the sky and recorded. However, "something" genuinely recorded may not be the same "something" that you or someone else thinks.
Although it looks like a meteor and probably is one, that "genuine something" may still be something completely different, and you have no base to prove it, other than "but it looks like...".
About 2030 years ago, one particular government had all the first borns killed when they saw a falling star. This should be enough reason to not blindly follow the first convenient explanation and dismiss everything else without even a thought. Only because someone says it is an omen, that needs not be. Only because someone says it's a meteor, that needs not be either.
Mr. Zhirinovsky seems to be convinced that the phenomenon was an US nuclear missle because Mr. Kerry was pissed off by something. Or so he said in his speech. Whatever. Now don't concentrate on how disturbed this is or whether might be true. Just consider its immense propaganda value.
And with that propaganda value in mind, you should at least deem it not impossible that an ultra-hardline nutter who likely has a way of getting hold of a nuclear missle (if you have some spare money, you got a bomb) detonates a missle in a sparsely inhabited area. It's not like Rome hasn't burned before. Nero did it, Hitler did it, and Bush did it -- why is it impossible and entirely laughable to consider that Zhirinovsky might. I'm not saying that he did, but it is a possibility.
Yesterday, it was said that the major part of the remains after the explosion fell into lake Cherbarkul (how convenient), and today some alleged tiny pieces have been found near the lake. Apparently someone found (or made) a 6 meter hole in the ice, too. Nice facts, so there's proof it was a meteor falling into the lake.
This reminds one of Nostradamus' prophecy. Something about a burning star falling from the sky and the Mediterranean Sea evaporating in 1999, remember? Oh wait, he's a couple of years late, and it's not quite the Mediterranean either. But hey, did someone say "evaporate"?
Vilem Otte calculated a kinetic energy of 1602TJ a few posts above. Let's assume that is the correct number, and assume that only 1% of this was left in the big piece falling into the lake afterwards. In the car video, what came after the boom still looked "quite big", so that's probably a conservative assumption.
This meager 1% is still the equivalent of heating 4 million cubic meters of water by 1°C, or alternatively, making 41,000 cubic meters of 4°C cold Lake Cherbarkul evaporate (that's approximately one third of the lake!). I didn't see a huge mass of steam rise from the ground in the videos, did you? I didn't read about hundreds of people getting burns in hot steam, nor about a flood wave destroying houses near the lake, did you?
Surely the meteor must have stopped moving by now. Where did the energy go?
