The first theory of the end of the world is that an asteroid or kind of planet is suposed to hit the and destroy us all, but it's fake because we would be able to see it during the night, it would be bigger and brighter than the moon. I had the idea to use a majora mask reference to eplain this, tomorrow and the day after, I will publish 2 other theory that are totally fake. If you want, show this to your friends who are afraid. Don't believe me? go to the NASA webstie
