Discussion Overview

The discussion revolves around the concept of what lies beyond the infinite universe and its expansion, exploring theoretical implications, observable limits, and the nature of dimensions. Participants engage with ideas related to the observable universe, the notion of multiple dimensions, and the temporal aspects of the universe.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants propose that if one could reach the end of the universe while keeping up with its expansion, questions arise about what exists on the other side and whether it is infinite.
  • Others argue that there is no definitive end to the universe, suggesting that one cannot catch up with it.
  • A participant mentions the observable universe, suggesting that reaching its edge would still result in seeing similar cosmic structures as from Earth, implying a continuity of observable phenomena.
  • Another participant introduces the idea of "bubbles" of galaxies, indicating a conceptual understanding of multiple dimensions and how they might relate to different observable regions of the universe.
  • One participant asserts that the "other side" of the universe is the past, emphasizing that we are surrounded by temporal aspects and cannot perceive the future of the universe.
  • A later reply references M-theory, suggesting that our universe consists of 11 dimensions and reiterating the notion that the edge of the universe is temporal.

Areas of Agreement / Disagreement

Participants express differing views on the nature of the universe's edge and what lies beyond it, with no consensus reached on these speculative ideas. The discussion includes both agreement on certain concepts, such as the temporal aspect of the universe, and disagreement regarding the existence of an "end" to the universe.

Contextual Notes

Participants' claims depend on various assumptions about the nature of the universe, dimensions, and the concept of time. The discussion does not resolve the implications of these assumptions or the definitions of terms used.

Let's say we caught up to the end of the universe and we're keeping up with its expansion. What's on the other side? And is the other side infinite? Will the universe have to stop expanding if its not infinite on the other side

There is no end of the universe. You cannot catch up with it.

I assume you're speaking of the observable universe. In this case if you get to the edge you will neccesarily be 'keeping up with expansion' relative to your starting position.

What wil you see though? In my non-scientific understanding of things you will see exactly the same sort of things that you would see in space from here. The observable universe will be a new bubble and Earth will be just on the outer edges of it. (assuming you traveled there instantly)
 
I think I understand the bubble thing. Its the whole different levels of multiple dimensions. I mean I remember reading about how there are different bubbles filled with galaxies or a universe
But besides that I get it what your saying thanks

Ah, when I used the term 'bubble' I specifically meant a new 'sphere' of observable universe. Everything will appear the same as it does here and you will be able to see roughly the same distance away as you can from here. It's still part of our universe, and the observable parts would overlap a bit.

It's slightly confusing in words. Maybe someone has a diagram of what I'm talking about. :-p
 
We already are at the temporal edge of the universe. The other 'side' of the universe is the past. We are surrounded by the past and cannot 'see' the future of the universe.
 

This video is a brief explanation of the 4th dimension. According to M-theory our universe has 11 dimensions. time is also a dimension. As chronos said the edge of the universe is temporal and the "other side" is the past.
