#  Moreover it is assumed that wormholes only join universes…

![“Moreover it is assumed that wormholes only join universes to baby universes, or universes to themselves; there are no wormholes joining different baby universes in this approximation, nor are there allowed to be wormholes which split up into two or more other wormholes.” quote by John D. Barrow](https://sms4smile.com/quotes/i/c49/john-d-barrow-4552_wormholes_moreover-it-is-assumed-that-wormholes-on_735352.jpg)   [Download](https://sms4smile.com/quotes/i/c49/john-d-barrow-4552_wormholes_moreover-it-is-assumed-that-wormholes-on_735352.jpg) [Open image](https://sms4smile.com/quotes/i/c49/john-d-barrow-4552_wormholes_moreover-it-is-assumed-that-wormholes-on_735352.jpg)

> ““Moreover it is assumed that wormholes only join universes to baby universes, or universes to themselves; there are no wormholes joining different baby universes in this approximation, nor are there allowed to be wormholes which split up into two or more other wormholes.””

## About This Quote

This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.

Wormholes are theorized to connect a universe to itself or to a baby universe, but not to link separate baby universes or split into multiple wormholes in this model.

**In simple terms:** Wormholes link a universe to itself or a baby universe, not separate ones.

Key Takeaway

Consider the limits of wormhole connectivity.

Themes

physics cosmology theory

Mood

curious speculative

Type

scientific theoretical

When to use this quote

- theoretical research
- science fiction writing
- educational lectures

Key Concepts

General relativity topology multiverse

Questions to Reflect On

- What constraints does this model impose on multiverse theories?
- How might alternative models change the connectivity?

A Different Perspective

Wormholes may behave differently under other approximations.
