The string theory I know and admired the ELEGANT MATHEMATIC SOLUTION but as a conservative or probably unoriginal shopper, it seem very hard to agree and especially,to understand this Theory,
but,D-brane,seem extremely attractive for a guy like me. The attractive aspect of thermodynamics,Quantum mechanics,nucleus,Maxwell,Born...and on ..and so on........
I reject too many aspect of the STRING..........as a blind and of coarse,old school guy,without cosmology degree.
now I have this or one of those problem if neutrinos just pass right through our planet and some time be detected but rarely with an atom of liquid,
non,zero mass and the electron volt
trivial my admiration the meaning of Nature the lack of neutrinos in our sun, directly inspired me
I seem a way to create ,a Boundaries
but it involve for each department or sector Theory,from all of and without mixing each of their own conception,
each Theory belong to their Law, I will believe some standard regarding zero will be appropriate and just easier to computation.
