Expanded string quantum-field theory {M-theory}| adds vibrating disks, blobs, toruses, and higher-dimension branes, to explain elementary particles, forces, and energies. M-theory branes create space-time (background independence). M-theory has ten space dimensions (three infinite and seven curled up) and one time dimension. People do not yet know M-theory physical principles.
