Meteorite Hits Russia

Light travels faster than Sound.

Holy Tunguska event!

Haha this sounds like an x-files reference?

Someone call agent Frentzen!

Well know we know what Michael Bay got wrong.

Thank goodness it crashed into a frozen lake.
Other possible targets would have been a bummer.

There is something which I never realized and apparently many Russians didn't either. It is that the sonic boom arrives a lot later than the flash of light. The same way thunder comes after lightning. Most of the Russian injuries were because of broken glass, probably because they saw a flash of light and walked to the window to see what it was. Than a little later the sonicboom blows the glass right in their face. Now I know, thanks Russia

Without sounding rude, how on earth could you not know the speed of light is faster than the speed of sound?

Classic example is the PEPCON explosion, complete with visible shockwave.

In that video one of the people speaking says "we watched the shockwave crawl up the mountain at lightning speed". I guess he didn't quite think out the words either.

I never thought about people going to the window after seeing the flash, and it makes a lot of sense.

From a recent news article they were estimating the meteorite at 10,000 tons, traveling somewhere around 40,000 MPH. Roughly equal to a 470 megaton explosion.

That my friends, is a LOT of energy transfer. Good thing most of it took place in the air.

Roughly equal to a 470 megaton explosion.

Surely, the standard unit for measuring big explosions nowadays is 'Hiroshima'? So, take your megatons elsewhere, good sir, and tell us how many Hiroshimas the meteorite produced?

Of course I know that. But I didn't know that a meteorite that enters the atmosphere could produce such a large shockwave.
If I saw a large flashlight in the air, my first instinct would have been to go and have a look, not crawling under my desk. Obviously a mistake I realize now.
