Discussion Overview

The discussion revolves around whether bounce theories in cosmology consider the role of existing elements during cosmic collapses, specifically focusing on the rearrangement of elements and the conditions under which they exist. The scope includes theoretical implications and conceptual considerations related to cosmological models.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants question whether bounce theories account for existing elements or if these elements are simply rearranged during a bounce.
  • One participant notes that in familiar cases of bounce theories, conditions are too extreme for ordinary chemical elements to exist, likening it to a big bang scenario resulting from a prior collapse.
  • A participant introduces a speculative idea suggesting that for our universe to exist as it does, everything must be "coded" to survive a bounce, implying potential variability in the outcomes of such events.

Areas of Agreement / Disagreement

Participants express differing views on the treatment of elements in bounce theories, indicating that multiple competing perspectives remain unresolved.

Contextual Notes

The discussion highlights limitations regarding the assumptions about the conditions during a bounce and the definitions of elements in extreme environments, which remain unresolved.

Do bounce theories take account of existing elements, or are these elements re arranged when
a bounce happens.

rearranged, wolram.
In the cases I'm most familiar with, conditions are too extreme for ordinary chemcial elements to exist. It's more or less the big bang scenario we are used to except that it results from a prior region of space and matter collapsing. I'll look at your link

Just a stupid idea that for our U to exist as it is ,every thing must be coded to survive a bounce, other wise we could get a Van Gogh or Lowry universe.
