Question:
So conspiracy theorists like to believe that 2012 is the end of the world, others believe in the polar shift theory, others feel that the galactic alignment will happen.

So I feel that end of the world is slightly illogical, galactic alignment is possible however highly improbable. I’ll tell you however, I have a theory theory I just thought of:

Maybe (if and only if) a polar shift happens, then all computer hard drives will experience a magnetic “flip” and lose all of their data (mirroring it exactly)

what do you think?? and what’s your theories??
