Do extra dimensions lead to expansion of our universe?

Click For Summary

Discussion Overview

The discussion revolves around the implications of extra dimensions in gravitational theories and whether they could lead to the expansion of our four-dimensional universe into a higher-dimensional space. The conversation touches on theoretical aspects and the validity of published research in this area.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant references a paper suggesting that extra dimensions may be unstable and could cause the expansion of our universe into higher dimensions.
  • Another participant questions the publication status of the referenced paper, implying skepticism about its authority.
  • A subsequent reply clarifies that the paper is indeed published in a reputable journal, countering the skepticism expressed earlier.
  • A later response acknowledges the misunderstanding regarding the publication status.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the implications of extra dimensions, but there is agreement on the publication status of the referenced paper. The initial skepticism about the paper's authority is challenged, indicating a division in perspectives regarding the credibility of the claims made.

Contextual Notes

The discussion does not resolve the theoretical implications of extra dimensions or their potential effects on the universe's expansion, leaving these aspects open for further exploration.

Quite an authority ! But it looks to me as if he didn't get this one published ?

It's clearly visible in the link that it's published, in Phys.Rev. D68 (2003) 026006.
 
Thanks ! o:) My bad...
