It doesn't mean the Sun disappears it just pops every 12,000 years or so in a micronova it's like a huge electrical discharge. It could possibly trigger the magnetic pole shift which would be the real problem. We can survive the Sun Nova thing, what freaks me out is when the ocean starts sloshing around, supposedly the last time the Poles shifted the crust of the earth moved like 90° and the Pacific Ocean sloshed over the Rockies.

Whatever ideology survives this cataclysm will determine who rules the world for the next 12,000 year cycle, this is why the elites have bunkers everywhere.
