Discussion Overview

The discussion revolves around the concept of sub-universes within an infinite multiverse, exploring whether these sub-universes could be part of a larger universe or if they should be considered entirely separate entities. Participants examine the implications of observability and the nature of separation between universes.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • Some participants propose that if there are infinite universes, they could potentially be sub-universes that contribute to a larger universe, questioning why they should be considered separate.
  • Others argue that universes should be separated because events in one universe cannot have observable effects in another, suggesting that they are not compatible.
  • A participant emphasizes that if something cannot be observed or reached, it may not exist in our reality, supporting the idea that there can only be one "Universe."
  • Another participant raises the question of how space and time would function if there were other universes, implying that they could not be separated from our universe.
  • One contribution discusses Schrödinger's theory and the Multiverse theory, suggesting that every possible event occurs in different universes, but this remains a simplification.
  • A later reply notes that any event in another universe cannot be detected in our universe, highlighting the challenge of providing observable proof for theories about other universes.

Areas of Agreement / Disagreement

Participants express differing views on whether sub-universes should be considered part of a larger universe or entirely separate. The discussion remains unresolved, with multiple competing perspectives presented.

Contextual Notes

Limitations include the dependence on definitions of "universe" and "sub-universe," as well as unresolved assumptions about the nature of observability and separation between universes.

Say if there were a large to infinite number of universes, why can't they be sub-universes that make one big universe that accounts for everything. Would it be because the other universes behave differently than the one we observe or perhaps some other reason? I don't see why we would separate them as a different universes when it could just be part of something bigger.

What are your thoughts on this?

this is a common misunderstanding.

one would separate these universes because there is no reason to have them in the same group. what happens in one universe can have no observable effect in another, therefore they are not compadable and should not be grouped together.
 
what happens in one universe can have no observable effect in another

If we can't observe it and there's no way we can get there, then that basically means it's not even there in our reality.

Exactly, which is why "sub-universe" is a good term, as there can only be one "Universe".

Also, think of this: Space and time exist within our Universe, do they not? So, if there were such a thing as another "Universe", it would be separated from us by... ... ... well, nothing. It couldn't be separated from us at all, could it?

That's a good question. I think we need to know more about our universe before we start to go into thinking about other universes. But I just want to hear what all of you think.

And yours is a very valid question, giving the fact that one explanation of Schrödinger's theory is the Multiverse theory (which postulates that, every time some event occurs, the other possible events (that could have occurred at that time) also occur, but in different Universes). This is a simplification of Multiverse theory, but it suffices to explain why the concept of other Universes (separated from us by nothing at all (Run through the E.i.N.S.-->
"Not separated from us by anything at all)) is still studied by scientists.
 
it's not separated by us by anything (or nothing), you're right. but to simplify: the light cone of any event in another universe cannot be detectable in our universe. any speculation about other universes must know that there can never be any observable proof to ever support a theory.
