Atiyah's k theory 2*3.14*(2-2(3))=-8*3.14 for string theory which vacuum energy(ch=(4.9154)^3 time proton's mass (pm=1.67262*10^-27 kg)) have symmetry at Planck , proton, Atom scale, form landscape of general relativity 8*3.14*g*Tuv/c^4, plus SR Tuv=(mc^2/2)^2 deduce 2 dimensional vacuum energy ch=299792458*(6.626*10^-34) = 2*3.14*gm^2=2*3.14*(6.674*10^-11)*(2.17647*10^-8)^2 form a 6 extra dimensional calabi yau manifold of string theory, which embedding in our 4 dimensional space time by Nash's embedding theory -5(3(-5)+11)/2=6+4, 11 dimension is super symmetry of string theory require, 4 dimensional dynamic space time from k theory (2-3(2)= -4 put in Nash's theory -4(3(-4)+11)/2= 2 become a 2 dimensional vacuum energy ch.(ch=2*3.14*l*mc^2=2*3.14*pl*pm*c^2/4.188=2*3.14*A*me*c^2/137,pl=8.8*10^-16,A=5.29177*10^-11, me=9.10938*10^-31)
