Discussion Overview

The discussion revolves around concepts related to string theory and M-theory, particularly focusing on the nature of atomic particles, their behavior in dimensions, and the relationship between string theories and M-theory. Participants explore theoretical implications and interpretations of these ideas.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant suggests that atomic particles may not flicker into and out of other dimensions but could instead be moving rapidly, creating an illusion of flickering.
  • Another participant questions the notion of strings "evolving" into membranes with the addition of the 11th dimension, indicating that this is not an evolution but rather a discovery of relationships among various string theories as special cases of M-theory.
  • A participant seeks clarification on what is meant by "special cases" in the context of string theories and M-theory.
  • One participant provides an analogy comparing the relationship between different string theories to different studies of gravity, suggesting that they may appear unrelated until viewed as part of a larger framework.

Areas of Agreement / Disagreement

Participants express differing views on the nature of particle behavior and the relationship between string theories and M-theory. There is no consensus on these interpretations, and the discussion remains unresolved.

Contextual Notes

Some assumptions about the behavior of particles and the definitions of string theories and M-theory are not fully explored, leaving gaps in understanding the implications of these theories.

I was watching the Parallel worlds movie on Dr.Kaku's website and I got to thinking. Just because it is utterly impossible to pinpoint the positions of atomic particles doesn't mean they flicker into and out of other dimensions.

They could just move very rapidly Making them just look like they flicker in and out of existence.Why is it thought that the particles flicker into different
dimensions ?

I was also wondering why the strings(in string theory) "evolved" into membranes,just because the 11th dimensions was added.

Any thoughts?

It wasn't exactly evolution. The people working in the field discovered that the various string theories are special cases of m-theory.

What do you mean by "special cases"?
 
I can't claim expertize to answer in detail. Try Brian Greene's book.

If one scientist is studying ICBM missile ballistics and another is studying the movement of the Moon, someone else might come along and say you're both studying gravity and each is a special case of orbital mechanics.

The same with string theory. Different theories put forth by different factions seemed to be barely related or even competing, until someone(s) showed that, if you step back far enough, you show that they are all part of the same bigger theory.
