All a theory is is a educated guess. That being said upfront you will see below many theories that are being tossed around.
World changes, economic meltdown, comets, natural disasters, all are possible. Here are some hits i found on u-tube.
Keep in mind this is all theory, ideas that make you stop and think. What if all of this is going on? What should one
do? Well in my case I live life like normal, try to keep up with the possibilities, and i have all my stuff ready for
a disaster. After all my countless hours of reading and research i know that something is going on, but i am not sure
when or if it will change my normal life. If anything happens i am ready. Are you?
