With my knowledge and experience I find the principle of parallel universes (to the infinite extent propounded) as most improbable.

In particular I can see no 'purpose' or advantage for Nature.

I do not presume, however that Nature has purpose!

Fractal grown on other fractal, each utilizing elements of each other.
Thank you for the link Rhymer.

It's one of the most useless concepts conceivable.

I disagree Rick.

The concepts of Parallel Universes (Worlds) are very important in physics.

There is a chap -Theophrastus Bombastus von Hohenheim Paracelsus having expressed interesting issues on the topic.

The "many worlds" interpretation of quantum mechanics is less useful than the Copehhagen interpretation, which is fundamentally incorrect. I like Bishop Berkeley's view.

Oh my dear Bishop Berkeley. How I love that clever man.
I think the best way is to approach to the problem from the Fluctuation Theory rather than quantum mechanics.

The correct interpretation may not be the most "useful" one.

Care to elaborate, sir?

stop thinking literally and start thinking metaphorically

No.

It isn't always easy to elaborate on problems that don't exist.
