"The end of the world" scenario

"The end of the world," something people have been saying, writing about, waiting for, and visualizing for thousands of years.  What would you do if one day you turn on the t.v., and there, on CNN, a video of an incoming meteor or comet. A live video, you are watching this in real time. You change the channel because you were not in the mood for gloomy "end of the world" scenarios. Yet, in the middle of your favorite soap opera, all of a sudden, "breaking news" appears on your t.v. screen. Your heart starts pounding like a beating drum at the sight of the same video of the meteor you saw a few minutes ago on CNN, but dismissed it as a "what if this were to happen" segment. You try to pull yourself together, and try to convince yourself that "nah, this can't be happening," and once more you change the channel, still trying to convince yourself that this has to be some kind of hoax. And for a few seconds you succeed, because you remember hearing or reading somewhere how in the 1930's an actor named Orson Welles, did a radio broadcast entitled "The War Of The Worlds," which caused widespread panic, because the listeners believed a real invasion by aliens from outer space was really happening. Yet, when you change the channel no such luck. There on your 52' Panasonic high definition smart t.v. is an image of an incoming meteor the size of Texas, and the NASA scientists and physicists all agree that if the speed of the meteor remains constant and or does not change its trajectory. It will slam into the earth in 38 hours; nowhere near enough time to figure out a solution. Now what? What do you do? Where do you go? Who do you call? Who do you see.
