What Is the New Geometry of String/M-Theory?

Click For Summary

Discussion Overview

The discussion revolves around the concept of a new geometry suggested by String/M-theory, particularly focusing on the interactions between quantum world sheets rather than traditional space/time points. Participants are exploring the implications of this geometry and seeking further information on the topic.

Discussion Character

  • Exploratory
  • Conceptual clarification

Main Points Raised

  • One participant references a lecture by Edward Witten, noting that String/M-theory hints at a new geometry involving quantum world sheets.
  • Another participant provides a link to a reference that may contain more information about the interactions between quantum world sheets.
  • It is mentioned that while these world sheets are considered, they are still embedded in a 10-dimensional background, suggesting that this may not be the final understanding of the geometry.
  • A participant humorously notes the anticipation for Witten to publish his background-independent notion of string theory.
  • One participant expresses agreement with the previous points made in the discussion.

Areas of Agreement / Disagreement

The discussion does not appear to reach a consensus, as participants are exploring various aspects of the new geometry and its implications without settling on a definitive understanding.

Contextual Notes

There are references to ongoing work and the need for further publications, indicating that the topic is still under exploration and may depend on future developments in the field.

I'm watching a lecture by Edward Witten here:

In it, he mentions that String/M-theory seems to be hinting toward a new kind of geometry where you don't talk about space/time points, but the interactions between quantum world sheets (around 37:00 minute mark.)

Does this new geometry have a name? What work's being done on it? Where can I read more?

But these world sheets are embedded in 10-dim. "background", so this cannot be the final answer
 
We are still waiting for Ed to publish his background-ind. notion of string theory, I guess :P
 
You're dead right!
