I find it interesting that Mars has had its atmosphere eradicated , with no chance of getting it back while all the solar winds are hammering the planet.
The earth has been through these nova,s every 12000 years and mankind has not been extinguished ,somehow managed to survive and even managed to repopulate the planet by 7 and half billion to date.
Back 12000 or 24000 years they never had the technology we have to date ,they had knowledge!Of what and where from did this knowledge come from,why did our ancestors leave links and drawings to warn us of the novas that would hit again and again?
They knew mankind would survive somehow and sow the seeds for the next 12000 years.
How and why?

Lets say we have about 27 years left!
Could this be the reason for Cern,to find a way to open portals to another dimension or to change timelines to avoid the inevitable.

Underground bunkers and cities would this be enough to protect people from a shifting mantle and pole shift?
really?

When the sun nova,s every planet in our solar system will be affected.
Our safe zone would be to find a way out to a new planetary body able to sustain life in a Goldilocks zone.
Hence the trillions spent on antigrav and the reasearch to travel across space using magnetic ley lines of space to travel from planet to planet.
