Discussion Overview

The discussion centers on the concept of the multiverse and whether the universes within it revolve around each other. Participants explore the implications of multiverse theories, including their origins and the nature of their interactions, while also questioning the scientific basis of such claims.

Discussion Character

  • Debate/contested
  • Exploratory
  • Conceptual clarification

Main Points Raised

  • Some participants question whether the multiverse exists as a scientifically supported concept, suggesting it may be more speculative than factual.
  • One participant mentions that while some string theorists and inflation scenario creators entertain the idea of a multiverse, it is not widely accepted or considered in regular cosmological research.
  • There is a reference to Steinhardt's model involving 3D branes that interact rather than revolve, indicating a different conceptualization of universes within a multiverse framework.
  • Another participant introduces the idea of multiple interpretations of quantum mechanics leading to the concept of multiple universes, questioning the necessity of these interpretations.
  • A suggestion is made to visualize the universe as a balloon with a 3D hypersurface, with a query about extending this analogy to branes.
  • One participant proposes that manifolds could revolve around a center of energy, prompting a request for clarification on the definition of energy in this context.
  • Another participant notes the existence of a 'landscape' of possible origins for the universe, emphasizing the challenge of providing observational evidence for these speculations.

Areas of Agreement / Disagreement

Participants express differing views on the existence and nature of the multiverse, with some questioning its scientific validity while others explore speculative ideas. No consensus is reached regarding the multiverse's characteristics or the implications of its existence.

Contextual Notes

Participants highlight the speculative nature of the multiverse concept and the challenges in obtaining observational evidence. There are also unresolved definitions and assumptions regarding energy and the structure of manifolds.

If the multiverse exists as the scientists claim then do they revolve around each other?
Can we ask which universe is at the center ?
If not why ?

I'm not sure any scientist CLAIMS that a multiplicity of universes exists. It is a speculation (unsubstantiated fantasy), that some engage in.

Very few professional cosmologists spend much thought on it. It just doesn't work into regular day to day research. So it doesn't come up much in research articles published by the astronomy/cosmology people.

But some string theorists like the idea, and people who construct imaginative inflation scenarios. Some of them write about it.

So I can try to answer your question based on not on CLAIMS (which need some evidence) but on the fantasies or speculations of a few people mostly outside observational cosmology.
In fact, in all the speculations I've seen, different pieces of the imagined multiverse are NOT imagined as orbiting each other.

However Steinhardt (also inflation scenario inventor) has a picture of a 4 or 5 dimensional universe in which 3D branes BUMP against each other every trillion years or so. But he doesn't call the separate 3D branes "universes". The 3D sheets are part of the same universe because they can interact, that is bounce against each other. We are imagined to live on one of these.
Again this is pretty exotic and not something that a working cosmologist would normally be considering.

If you fancy the idea, however, you could read Steinhardt's new popular book about it called Endless Universe. Look it up on Amazon.

Many world interpretations of Quantum Observation also lead to Multiple Universes.
Which interpretation of Quantum theory is widely used and why ? Why so many interpretations are required ?
Intially I thought it was a good idea to imagine universe as balloon with 3D hypersurface.Can we extend this analogy to branes ?
Thanks

2 manifolds could revolve around some sort of center (say center of energy) outside of the manifolds. Centers of energy can be outside manifolds, such as for a torus.
 
Define 'energy' "outside of the manifolds". :rolleyes:

The are a 'landscape' of possible ways the universe may have originated - and it's fun to speculate. Providing observational evidence is the hard part.
