Using simplifying assumptions, a region or time in the universe is conceived, which allows for a state constituted solely by a gaseous plasma subject to the current laws of gravity and electromagnetism to exist. Under these conditions, it is proposed that the presence of a portion of that medium, organized in a highly symmetric magnetic field and plasma structure, possesses the symmetry of a torus. We resort to the fact that magneto hydrodynamics (MHD) is the common state of this medium and that it has the property of attaching to it the mass. (I.e. in the language of MHD the mass of the torus is assumed to be magnetized.) The solution to this MHD equilibrium of the matter of the torus, which prevents it from coalescing through the gravitational pool, is presented. Further, analysis shows that a gravitational field generated by the torus may be capable of attracting the other, non-magnetized matter, under the influence of the torus’ gravitational pool. In this way it is shown that the torus shaped MHD structure, under the discussed conditions, satisfies essential properties, like having large regions where the Keplerian mass motion cannot be present. A scenario consistent with a few key properties of proto-nebulae in equilibrium is presented and considered.
