How is string theory related to MWI?

Click For Summary

Discussion Overview

The discussion revolves around the relationship between string theory and the Many-Worlds Interpretation (MWI) of quantum mechanics. Participants explore concepts such as the existence of other worlds, the possibility of traveling between them, and the manipulation of matter through sound waves, touching on theoretical implications and speculative ideas.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions whether other worlds in the MWI exist in adjacent branes and speculates on the possibility of journeying to another world, suggesting it might require significant power or the creation of a wormhole.
  • Another participant asserts that all MWI worlds exist in the same space, contradicting the brane theory perspective.
  • A participant challenges the feasibility of manipulating matter by altering the vibration of strings, expressing skepticism about the idea of using high-frequency sound waves for such purposes.
  • Concerns are raised about the potential dangers of sound waves, with references to specific frequencies that can cause harm, while also dismissing the notion of changing matter as unrealistic.

Areas of Agreement / Disagreement

Participants express differing views on the nature of MWI worlds and their relation to branes, with no consensus reached on the possibility of traveling between worlds or manipulating matter through sound waves.

Contextual Notes

Participants reference complex theoretical frameworks, including the dimensionality of branes and the nature of Hilbert space, without fully resolving the implications of these concepts. The discussion includes speculative ideas that lack empirical support.

Are other worlds in the MWI existing in adjacent branes?

If one could bend the rules as currently defined, and one wanted to journey to another world under the MWI idea, how would you accomplish it? Is this ever discussed? Would it require fabulous amounts of power? Creation of a worm hole?

One final question, what are the odds of manipulating the nature of matter by manipulating the complement of the strings or rates of their vibration within the particles contained in matter?

On a scale from 1 to 100 (1 being completely retarded and 100 being completely genius) what rating would you give someone who told you they were pursuing a way of changing matter by flooding it with high frequency sound waves?

Sorry in advance if these questions are lame. I have the unfortunate condition of being immensely curious at the same being totally uninformed. Working on that second bit though.

No. All the worlds exist in the same space.

You cannot. If you could then MWI would make a different prediction than other interpretations - but it doesn't.

The odds are 100% that this is just a science fiction collection of buzzwords.

No. Branes live in a 9 or 10 dimensional space (not counting time as a dimension). MWI worlds live in an infinite dimensional Hilbert space.

Is this something you are contemplating, Calvin, or something someone else has claimed? Certainly, sound waves can damage us - 19 Hz is the resonant frequency of the human eyeball and very loud noise at around 5 Hz can make your breathing erratic and shake your bones. At the gruesome end of things, apparently your head would explode at 240 dB, which may not be changing matter, but it definitely does matter to the person who's head it is.

But if you're expecting to turn lead into gold, or some such fancy where objects change their constitution with ultrasound, then you are out of luck. It's a #1 on your scale.
