It's possible e, as the inflation theory stated. Pero the rules of that universe are not the same as the rules of our universe may ganern. Di natin alam na may exact tayong copy sa universe na yon, siguro yung sinasabi mo hindi multiverse kundi parallel universe or alternate reality na kumbaga parang copy mo, katulad mo pero may mga slight or big changes. Siguro sa alternate reality na yon president ka or sundalo ka.
It is a interesting topic yan, meron ding tinatawag na simulation theory. Na sinasabing nasa simulation lang tayo, pero 50\50 chance yan. Kasi it is either tayo ang pinaka unang gagawa nyan, or tayo ang pinaka huli kasi di pa natin nadedevelop ang virtual simulation ng isang universe.
