The Nothing has been said to be infinitely vast. But a truth is, we are inside of it. While it is the structure of dimensions, one thing remains true. If we can be inside of it, it must have at least one feature of self containment.
A expectation of the infinitely never ending Nothing is the retraced footprints theory. If one were to walk forward and never stop, eventually they would rewalk over their own old footprints.
Its similar to a flat world map, you cintinue in a straight line, you return to where you started.
You may be thinking this is due to the Nothings shape, but it is possibly very complex, maybe beyond simple shape.
