Multiverse theory is a coping mechanism for people who are basically into hardcore nihilism without even knowing it. The most pathetic series of thoughts comes from those kinds of people:

>maybe my other self in a parallel universe didn't have it so hard
>maybe I'm rich in that other universe
>maybe I'm not a faggot tranny in that universe
>maybe I'm the boss in that other universe

Newsflash: you might as well believe in God or any religions for that matter, because organized faith is offering basically the same comfort without the useless pretentiousness pop sci offers.
