Perhaps they will be some day:
Physicists find way to 'see' extra dimensions

To express the conclusion that I have come to, concerning these ideas, the shape of photons might be considered as strings but the fundamental shape of mass, such as the electron or proton, should be considered as being composed of "bubbles," perhaps these bubbles then are made of 3 dimensional photon "strings." Anyway, interesting thoughts.

If there are other "dimensions" then those dimensions should also exist in 3 dimensional space.
We live in a universe where the "waves" associated with electrons, protons, etc., "weaves" everything that we experience.
Suppose that there exists an area of space where the frequencies in the x ray or gamma ray area would "weave" forms, similar to that which we are familiar with, (trees, animals, etc.)
Would these X-ray beings be in our universe, different universe or a different dimension?

Just some random thoughts.
