The n-dimension theory by Kaluza-Klein, who tried to unify gravity and the other forces, can be proved experimentaly in a lab? Can the folded dimensions be "seen" or felt by any experiment? The Calabi-Yau "simulators" can really express the folded dimensions, or is it just another "speculation"? Do we have enough energy in our labs to "see" this dimension-particles-forces?

what i'm saying is, even outdoors, if you encounter flies flying around on your porch, or above your lawn, they invariably fly around making right and left turns, getting nowhere.

i've seen it on sci-fi films all the time eg: event horizon, they create a singularity in order to fold space and travel to the other side of the universe. is it actually theoretically possible to do this, or likely that we will ever be able to? or would it swallow everything around it up like a black hole? and if so could it be used for far flung space travel and/or time travel?
