M Theory can be correlated with 3d Sphericalvolumes.The partitioning of rotating sphères more the fréquences and waves of spherical strings can be very relevant in fact.The dimensions are always in 3D ,that said we can correlate the computing with the 3D realism.The gravitation needs a real 3D cause.The rotations , motions and properties of sphères become a key.Gravitation appears when we have the correct serie of spherical volumes.The fermions bosons aren't sufficient.Our understanding of nuclei , protons are so weak still.We are so far of the main central singularity,the main coded stable gravitational sphere, the biggest volume.The dimensions are a fractal of a pure 3D.lie algebras and others algebras and M Theory can respect the 3D fractalisation in inserting rotating 3D sphères.The Hamiltonian, the Lagrangian,The Minkowski space time and the others models can be harmonised with determinism considering the universal proportions of our universal sphere.The gravitation needs a real causality.It is essential.
