I really am not feeling any panic. If the asteroid hit the ocean, it would 
obviously trigger a tsunami, but how much would it flood? If it hit land... 
a theory is that it will create a huge cloud of dust that will curcumnavigate 
the earth, blocking out the sun. Could humans survive under such conditions?
