Is String Theory valid?

String Theory advocates believe that all matter is connected; and, that all matter is constantly in motion,vibrating. Last year I was privileged to hear the nuances of string theory expounded on by the Dean of the Harvard School of Physics. She maintains that there are at least 11 dimensions, probably 24, and quite possibly an infinite number; and, that all multi verses are simply vibrations away from each dimension,and rest on thin membranes that would be analogous in the cosmos of multi verses to dimensional worlds on stacked pieces of paper, connected by thin, invisible threads, "the fibers of the universe".

Also, things that exist in one dimension are unable to perceive things that exist in two dimensions, but the things that exist in two dimensions can see and perceive full well the things that exist in the first dimension; things that live in the third dimensions can see the first two dimensions, but neither the first nor the second can perceive the third, and so on. She feels through the use of certain proton beam techniques, science will soon be able to see "shadows" of the forth dimension and even perform measurements on the "shadows" to confirm details that elude science presently, about dimensional multi verses, and beyond. Wow! What an awesome thought. Einstein said that imagination was more important than knowledge. I agree, for without imagination, we would still be eating raw food in caves. God bless the string theory physicists, they are the poets of science!
