SUMMARY

The work begins with the reinterpretation of the notion of "field" and unexpectedly reaches the conclusion thant the vacuum is an existence form of the matter in the state of field – fluen. This notice imposes from itself extremely interesting reinterpretations of the elementary particles, of the notion of mass, energy and generally of the fundamental phenomena of physics. The field state of matter, fluen, makes possible, efficient and much easier the space unlimited travel, not with the rocket‘s motor, not with the photonic motor supplied with antimatter but with the fluenic motor. The fluenic motor isn´t a compact object, detachable, it is a set of fixed functional elements, inbuilt in the structure of the mobile´s shell and that generate the propulsion force.
