This new physics Dual Centrifugal Synchrotron Thruster is based on a new physics compound Rigid String Theory called Quantum Function Follow Form Theory. In physics, it is well known that the three simplest Fermions differ in actual mass. From lightweight to heavy, they are called Electron, Muon and Tau particles. The Q-FFF Theory these propeller shaped particles are assumed to be spinning by collision with the local oscillating vacuum vector field called Axion-Higgs field with a torus shaped form. (figure 2) An electron is assumed to be equipped with 2 additional compound Photon/Gluons to form a Muon particle, which are heavier than the Electron. The measured mass ratio between Electrons and Muons are 1: 200 or about 0.5 MeV: 100MeV. ( figure 1.) Title: Electron- Muon- Electron string Conversion for Space flight (EMEC) The craft is equipped with two concentric storage tube rings with mutual electric radiation lasers based ring change channels producing Centrifugal Force for spaceflight. EMEC means Electron Muon Electron conversion. The mass difference between Electrons and Muon are supposed to be able by mutual laser conversion and ring changing to produce a centrifugal force strong enough to accelerate the Craft everywhere in space. (Figure 3) Together with additional Free vacuum Electricity production inside the craft, this system will be able to independently operate for space transportation. (Fig 12)
