You cannot get out of Universe. All the word out means is that you are not inside a system. You can only get out of systems. In designates individual experience foci. Foci are in, because focusable, but always, as entropy shows, temporary.
Relationships exist between the ins because they are definable.
Out is nothingness, i.e., nonexperience. Only the nonexperience nothingness constitutes continuum. There are no experimentally demonstrable continuums. All that has been found is discontinuity, as in star constellations or atomic nuclear arrays. Areas are discontinuous by constructional definition.
