That’s really a interesting hyperthesis with the parallel universe and i think it totally makes sense as everything has its kind of cycles, so we relive some kind of time chapter in new way. As you said people had other problems in the past, but what would interesting to know if they where happier overall during this times. I read/heard about a parallel universe portal somewhere in Africa and Antarctica, so I think this can change a lot when it will be truly discovered. Thanks for your thoughts
