The possibility of a solar eruption from the Sun which hits the earth is a VERY real possibility. A solar eruption recently occured that, had the trajectory of it been towards the earth, would have wiped out all electrical connectivity world wide, maybe even wiping a large portion of our atmosphere away! So, we would truly have an apocolypse. We are not prepareing for this and we really should. Buildings should be built Hobbit style, underground with HVAC systems designed to produce water and oxygen and food in the interior. We're like rats that when faced with certain death will busy themselves with non-important things, even knowing that the danger of dying is clear and present.
