There is a huge undiscovered mass in the vicinity of our sun. Superjovian planet, black hole, neutron star maybe.
It's on a highly elliptical orbit with a period of thousands of years. Right now it's out of our sight, but its massive gravity is affecting the earth's orbit.
Soon it will return, as it has many times in history, but this time it will come too close.
WE'RE ALL GONNA DIE.
This statement is true.
Old people and minorities will be hit hardest.
