." Is there some physic observation(s) involved in ST or is it just
a plain theory?"

" Is there any observation(s) that exclusively confirms ST?"


Till now the theory is not verified through any experiments but the people are expecting that
the theory will be verified by 2008-09 with the good accelarators LHC in CERN

" Why is the explanation of ST so hard so that any standard layman
can't understand it?"

Actually St is very pure in mathematics and it need a lot of knowledge of pure mathematics
for example in Differential Geometry and Functional analysis etc.
which is obvious as if you will try to get a unified theory you have to include gravity.
and as soon as you consider gravity there is curvature due to mass and then euclidien and minkoskion space are not the approprate one and you have to get an idea of doing calculus on manifold i.e. to get a very closer look of curved spaces in a crude sense..................

and mathematics becomes too much hard .
