In my understanding the multiverse represents several universes. These universes offer different possibilities (infinite) where some are different timelines of a given universe and some are unique with no variation.I believe the multiverse exists as a result of the concept that matter can never be created nor destroyed, but can be changed from one form to another.Hence, the end of a universe births similar timelines and similar universes(that is a universe does not really get destroyed but is broken into different forms). In essence, the multiverse is a collection of same Celestial components and matter but different views and order. It is everything outside our view of the main verse and what could be and what was.
Give me a call for a discussion. Thank you.
