Discussion Overview

The discussion centers around concepts presented in an interview with Michio Kaku, particularly regarding String Theory (SST) and its implications for understanding the nature of physics and the multiverse. Participants explore the properties and values that determine different "sets" of physics within SST.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant references Kaku's statement that SST represents "physics beyond physics" and questions what properties and values are necessary to define a "set of physics."
  • Another participant suggests that Kaku may be discussing the many vacua situation in M-theory, noting that some vacua are inequivalent, leading to different physical laws in those contexts.
  • There is a query about whether Kaku's claims are published or if he has presented them in a novel way, indicating uncertainty about the broader acceptance of these ideas.
  • Concerns are raised regarding the implications of these ideas for the falsifiability of string/M theory, referencing discussions by Susskind and others.

Areas of Agreement / Disagreement

Participants express varying levels of familiarity with Kaku's ideas and the implications of SST, indicating that multiple competing views remain regarding the interpretation and acceptance of these concepts.

Contextual Notes

Some claims about the nature of vacua in M-theory and their implications for physics remain unresolved, with participants not reaching consensus on the specifics of Kaku's statements or their broader implications.

Who May Find This Useful

This discussion may be of interest to those exploring advanced topics in theoretical physics, particularly in relation to String Theory and its interpretations.

Hi there everybody. I heard an interview recently, that was done with Michio Kaku (www.mkaku.org[/url]) and InfidelGuy ([url]www.InfidelGuy.com[/URL]) - you can listen to the interview on the frontpage in case you need a reference for my question.

The interview was basically about String Theory! Kaku made the following statement:

"SST is a physics beyond physics" and described how the possible variations of SST compile into one "set" of physics, depending on the strings values. And thus we have one "set" of physics, ours, from which this is the basis of physics.

And in part as you will hear, he mentioned multiverse, and related this to how the other universes "set of physics" would be the other derivatives of compiled sets of physics from SST.

So, my question is, how many - and what kind - of properties are their that need chosen values in SST that determin a "set of physics" ?

And in general, i was hoping some people here would know more about this so i can learn more. If you listen to the interview - it's 100% free on the frontpage, perhaps you can teach me more!

Thanks!

By The Way, I got here because of that interview but I have read Kaku before this.

And my name is the two names of my cats "Boz" and "Eon"...!

If you want you can call me Boz.
 
Anyone know if this is a published claim as well or did he just explain it differently than usual? Or maybe people don't really know about this? It's a rather specific subject I guess!
 
Kaku may have been describing the many vacua situation with M-theory. At least some of the vacua are inequavalent, which means there would be different physics between them. There has been some discussion about this, as Susskind and others have claimed this makes string/M physics unfalsifiable. See "Not Even Wrong".
