This process is very well known, for example in stars that, according to its initial mass, produce a residual body called White Dwarf, Neutron Star or Black Hole, depending on the initial mass of the original star.  In consequence, the ancestral explosion of the particle or star that might have given place to the universe might have also produced an extremely compressed body as in the above-mentioned cases of conventional stars. And this ancestral body is equivalent to the "Primordial Star" (PS) in the BF theory.  (Even if the Big Bang theory talks about an initial "particle" that exploded, it seems to me more reasonable to talk also about a "star" because of the enormous mass of the here considered body).

            We might still be able to detect the above mentioned PS in our universe. Since the PS would probably be still placed near the very center of the universe, it could be eventually used as "cosmic lighthouse" for future interstellar navigation and may be, even as unlimited energy source, once detected (Calvet¹⁵).

            In accordance to Bennett²¹, light can be thought of as "evaporated mass" and mass as "condensed light" according to the transformation equation, E = mc². If we take this principle and extend it to the above-mentioned scenario with a recently created PS, we will come to the conclusion that a body like the PS should effectively evaporate little by little when located inside a completely void universe. This process would be analogous to the "evaporation process" of Black Holes²⁰ and would in addition be a very likely source of the "Background Field" (BF).

            Since any particle (real or virtual) can be explained by strings, one important conclusion of the BF theory is that any kind of elementary particle has in principle the same origin and different particles are simply a different manifestation of the same ancestral string. This conclusion gives place to the possibility of transmutation of one particle into another (e.g. of matter into energy and of energy into matter) not only in an Einstein-like sense, but also in the sense that it might be possible to extract a virtual particle from a field of force and convert it into a real particle like a photon or even an electron. If humanity manages to achieve this goal, we would be able to manipulate the universe even far beyond the combined principles of nanotechnology and String theories.
