Can Altering String Frequencies Enable Travel to Alternate Dimensions?

Click For Summary
String theory posits that everything is made of "strings" vibrating at specific frequencies, which could theoretically allow for alternate dimensions. However, these dimensions are not hidden due to differing frequencies but rather because the strings are extremely short. The analogy of a rolled-up sheet of paper illustrates how higher dimensions can appear as lower dimensions when viewed from a certain perspective. The discussion clarifies misconceptions about the nature of these dimensions and the feasibility of traveling between them. Overall, the idea of altering string frequencies to access alternate dimensions is dismissed based on current understanding.

to begin, a few things

i am not a physicist or physics student
i am open to corrections and answers via both my email and thread
i am a new user and do not know if this is the correct place to post this

string theory states that every thing is composed of "strings" running at a certain frequency. string theory also allows for alternate or "parallel" dimensions. these dimensions are unseen because we are operating at a different frequency. if we were able to alter the frequency the strings forming a person operate at, and there was a way to stabalise the matter, could we not then travel to these dimensions?

No. the "parallel dimensions" are not unseen because of a "different frequency". (Strings in general have various frequencies.) They are unseen because they are very very short. Think of it this way: take a sheet of paper (2 dimensions) and roll it up into a very very thin cylinder. If the radius of the cylinder is very small (say, 0.01 mm) compared to the other dimension it looks like a line (one dimension).
 
thanks

thanks for that, cleared up a Q that had been on my mind quite a while
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
