How is the many worlds interpretation of QM related to the multiverse theory?

Click For Summary
SUMMARY

The discussion clarifies the relationship between the many-worlds interpretation of quantum mechanics (QM) and multiverse theory. It establishes that one can accept multiverse theory without adhering to the many-worlds interpretation, as multiverses can exist independently of QM. However, subscribing to the many-worlds interpretation inherently implies the existence of multiple worlds, contradicting the belief in a singular universe. The concept of a single tree of Everett's worlds is presented as a potential reconciliation of these ideas.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with the many-worlds interpretation of QM
  • Knowledge of multiverse theory concepts
  • Basic grasp of Everett's interpretation of quantum mechanics
NEXT STEPS
  • Research the implications of the many-worlds interpretation of quantum mechanics
  • Explore different models of multiverse theory
  • Study Everett's interpretation and its philosophical implications
  • Investigate how quantum mechanics intersects with metaphysical beliefs
USEFUL FOR

Philosophers of science, physicists, and anyone interested in the foundational concepts of quantum mechanics and their implications for understanding the universe.

To my understanding you can believe in the multiverse theory without subscribing to many-worlds interpretation of quantum mechanics. But can you subscribe to the many-worlds interpretation while also believing there is only this one universe (and that it just has hidden dimensions).

Can someone please help me understand how these are related?

Multiverses are just parallel universes (or even distant parts of a single universe) separated informatically (no information may leak from one to another). So you may think about them regardless your metaphysical interpretation of QM, actually you may think about them without bothering about QM at all.

In a strict meaning it is a self-contradiction: as the World splits into two (many) Worlds, we have many of them, not one.

But you may believe that there exist just one tree of Everett's worlds.
