The gravitational mass (passive and active) shows with what force the body interacts with the external fields of gravity, and what gravitational field this body itself creates, it is included in the law of universal gravitation and is the basis for measuring mass by weighing."
As we have already found out in the first issue of this series "The Paradigm of Gravity of Extraterrestrial civilizations" [1] gravitational mass does not exist in nature, since gravity is the interaction of the core of a star (planet, satellite) with the positive (light) matter of each proton, each neutron, and each atom nucleus (a separate elementary particle) of a test body consisting entirely of matter. Electrons do not participate in the gravitational interaction. The masses of elementary particles do not participate in the gravitational interaction. Positive (light) matter is attracted to the nuclei of space objects, and it just has no mass. The representative of positive matter is an elementary particle-a photon, which, as is known, has no mass. A photon is a free corpuscle of positive (light) matter in an excited state, which has increased its volume by a million times and emits electromagnetic waves.
Therefore, the determination of the mass of bodies by weighing is not quite correct, it is more correct, of course, to determine the mass based on the inertial properties of the mass, that is, based on Newton's second law. Moreover, positive (light) matter can quite easily leave the body and return back, which changes the weight of the body, so the dynamometric measurement of mass, which is now widely used in everyday life and practice, is incorrect for accurate calculations. This is proved by our experience [1]. For accurate calculations, the mass should be determined on a lever scale, carefully making sure that the temperature of the body being weighed and the disbalances for scales is the same. It is also possible (and perhaps necessary) to develop sensors for the acceleration of the body, because during acceleration there are inertia forces that deform the body, so the load cells can measure the acceleration.
We will continue to quote Wikipedia: "However, the proportionality of the gravitational and inert masses has been experimentally established with high accuracy, and by selecting units they are made equal to each other in theory. Therefore, when we are not talking about a special "new physics", it is customary to use the term "mass" and use the notation
