How is string theory related to MWI?

In summary, MWI worlds do not exist in adjacent branes and it is not possible to travel to other worlds under the MWI idea. Manipulating matter through sound waves is not possible and would be considered a 1 on the scale of genius.

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.
 

1. How does string theory relate to the many-worlds interpretation (MWI)?

String theory is a theoretical framework in physics that attempts to reconcile the theories of general relativity and quantum mechanics. It proposes that the fundamental building blocks of the universe are not particles, but tiny strings that vibrate at different frequencies. These vibrations give rise to the different particles and forces we observe. In the context of MWI, string theory is used to explain the existence of multiple parallel universes, as the strings can vibrate in different ways, leading to different universes with varying physical laws.

2. Can string theory provide evidence for the existence of parallel universes in MWI?

While string theory is often used to support the idea of parallel universes, it is still a theoretical framework and has not been proven or tested experimentally. Therefore, it cannot provide concrete evidence for the existence of parallel universes in MWI. However, it offers a theoretical basis for understanding how parallel universes could exist within the context of MWI.

3. What are the implications of MWI for string theory?

MWI has significant implications for string theory as it provides a possible explanation for the existence of multiple universes, which is a key component of string theory. In fact, many physicists believe that MWI is necessary for string theory to be consistent and complete. Additionally, MWI challenges the traditional interpretation of quantum mechanics, which is the basis for string theory.

4. How does MWI affect the way we understand the laws of physics in string theory?

MWI offers a different perspective on the laws of physics in string theory. In traditional interpretations of quantum mechanics, the laws of physics are considered to be probabilistic and only one universe is observed. However, in MWI, all possible outcomes of a quantum event occur in different universes, which challenges our understanding of the laws of physics and how they operate in the multiverse.

5. Is MWI accepted by the scientific community as a valid interpretation of quantum mechanics in string theory?

MWI is a highly debated topic within the scientific community. While some physicists support it as a valid interpretation of quantum mechanics and string theory, others reject it due to the lack of empirical evidence and its departure from the traditional interpretation of quantum mechanics. Further research and experimentation are needed to fully understand the implications of MWI in the context of string theory and its acceptance in the scientific community.
