I love these videos. Makes me actually appreciate that we are just living on a miniscule rock floating through space with so much going on around us that we have no idea about.
And I get a sense of time as well. This is the first time in my life I have seen and heard a meteorite hurtling towards earth but in the billions of years since the earth has been around, probably millions of meteorites have fallen to earth.
Makes me feel insignificant but not in a bad way.
Was the Russian government aware of the potential meteorite collision? You'd think so given that a lot of space agencies are looking for this type of thing. They just didn't want to tell The public as it may cause mass panic.
What if the one supposed to be 17 years away is actually a lot closer to us than governments are letting on, kinda scary to think about it.

Sky News were saying there may have been an impact crater located from one of the fragments.
Not only that but this piece of rock was fated to strike us since the inception of the solar system billions of years ago.

more pictures and videos.
well...the fake crater picture is there too......soo.......

I'm sure there was an impact, just not the same type of impact people are thinking. It won't be a fucking huge crater, but something small.

So it didn't land, right?
how do we know it's not Osama bin Laden coming back from heaven to kill us? how do we know it's not a frozen poop? how do we know...get that stupid shit outta here!!!!!!
If it passed 15 minutes earlier, it would hit the Earth.
smell o'vision.

Yeah that's what kinda makes it scary. Our of the whole entire universe, it flew into our path. And there have been millions of times in the past where far larger meteors nabs actually hit the earth and no doubt there will be more in the future, some which we will cause mass destruction.
The fact that we have gone pretty much all of humanity's recorded history without a big strike, as far as i know, just brings into realization how short humans have been around in the scheme of things.

Russian EMERCOM denied that the meteorite was shot down by AF.

Is this a piece of that asteroid that was passing close by today?
Why is no one reacting to it?
Why is no one reacting to it?
According to Phil Plait it's trajectory puts it at a completely different angle than the asteroid passing by today. So in other words its probably just a completely unlikely coincidence.
When in doubt, ask Phil Plait.

As it gets closer to the ground and the atmo gets thicker it does slow down, but that doesn't mean much if it's been going faster than sound the whole time. At some point the atmosphere becomes thick enough that if it's going faster than the speed of sound it will make the boom.
It's Russia. They don't care.

That was my first thought too.

I knew that the speed of sounds varies with altitude but i find it hard to believe that that object generating so much friction could lose so little speed to become supersonic only by losing height.
Another thing that comes to mind, if your theory is correct how could it be so slow while entering atmosphere ?
lol I klick on random song on winamp and what comes on: "Crashing in the Distance" by trog'low:

It's not slow at all. To break the sound barrier (make a sonic boom) you need two things. The object traveling faster than the speed of sound, and the atmosphere to create the "barrier". The meteor was traveling faster than sound, it just had to wait to reach atmosphere thick enough for the barrier to exist so it could break through it to create the boom.
I use to have a Time-Life book about ancient mysteries and unexplained phenomena and there was an article titled "Did A Black Hole Hit Siberia?"
The Verge has a nice compilation of all the videos and updated report.

The booms heard are the sound of a supersonic object impacting the relatively solid by comparison atmosphere. It's still a sonic boom, but just not the kind that you see at airshows.

man some of those dashcam videos are amazing. i would have loved to see that, but i probably would also shit my pants.

I didn't know a phenomenon like that exists. I'll go find some info about that, thanks.
I bet they thought they were under attack with those little explosions.
Actually, a sonic boom is caused simply by traveling faster than the speed of sound. It has nothing to do with the moment of crossing the sound barrier. A jet flying at mach 2 causes a sonic boom perpetually behind it. Anyone who sees it pass by will hear the sonic boom, no matter how long it has been flying at that speed. That is why all forms of supersonic travel are typically banned over populated areas.
Whenever an object moves through a medium such as air, it compresses the medium into a pressure wave. In the case of something traveling faster than the speed of sound traveling through air, those pressure waves become highly compressed and powerful, to the point where they resemble the pressure wave from an explosion. While it sounds to an obserer on the ground like an instantaneous thing, that is only because it propagates in thin cone shape that passes by you very quickly. However, that cone of sound is constantly following the plane flying at mach speeds. If another plane were to fly in the right spot, it could probably make a continuous recording of the first plane's sonic boom (if the pressure wave didn't seriously mess it up).

Supposedly hundreds of people have been wounded.
Edit: 700, 160+ kids.
They refer to it as a meteor shower, so more than one.
Edit: dozens

500 injured.
Vast majority not serious.
Edit: number went up to 725 as of posting this.

Damn, that shit as loud.
Learn you some science, friend.
That meteor is going to get the shit sued out of it.

Well that's some shit to wake up to on the internet.
There haven't been any confirmed accounts of a 'meteor shower' or even an impact. Most likely scenario is that the meteor broke up miles above the surface of the earth and the shockwave from that explosion caused the damage and injuries reported.
