If one were to somehow manipulate the strings of string theory that supposedly constitute the most fundamental aspects of reality, would this individual become able to warp reality?
Context: I'm thinking of a means by which some characters in my story begin creating reality-warping technologies which end up become a "magic system" thousands of years later, and I'm wondering if it'll be sufficient enough for me to say "in this universe, string theory is an accurate model of the universe, hence the characters becoming able to augment the physical universe and create faster-than-light technology and such."
It begins with an artificial means of "entangling" people in the "strings" and creating a megascale supercomputer that can link up to these "stringers" mentally so they can process the information required to concentrate on the individual strings. Does this idea seem believable given the concepts involved, or am I wholly misunderstanding what the strings are capable of doing?
Edit (some clarification):
Essentially I'm thinking of a naturalistic world that presupposes the existence of some kind of amalgam of the concepts of String Theory, the quantum foam, the Higgs Field, the Force from Star Wars, and some woo concepts like Aether, Akasha, ki, etc. And it does kind of fall into the "quantum physics can do anything" TV trope, except I'm trying to envision a fictionalized version of String Theory, because I don't want to peddle quantum mysticism (which I hate personally). I'm gauging my understanding of String Theory so I can make a more fantastic version of it for the sake of practical utility in my science fiction setting, and for the sake of consistency of this "magic system" (which is really the most advanced technology possible in this fictional setting).
I wanted my fictional world to be identical to ours up until the discovery of this hidden force on the smallest levels of reality possible, and that manipulation of this fundamental fabric would also allow some levels of reality heightening in localized areas, established using supercomputers and machinery that can interact with this underlying framework.
I'm not calling it String Theory at all; I'm making a fictionalized version of it that is based on the idea of String Theory—that the physical universe's most fundamental constituents are strings that vibrate in 10^500 different configurations. If one can theoretically alter the vibrational configurations of these strings, would that person be able to transmute any form of matter or energy into that of another, if the vibrational configurations are all that's required?
Never mind the means by which characters in this story are able to manipulate these "strings." I'm just seeing if I understand actual String Theory before I go any further.
