Some times we have gaps between our mental objects. These gaps usuelay usually [[RPE|puzzle us]] and we look for an explnation explanation or some intermidate intermediate MO that will close closes the gap. Therefore we invent an unseen MO to bridge the gap. When we invent the bridging MO, we usualy usually imagine it and we don't do not get if from phenomemologic phenomenological intervals (when we will further research, we will see that all MOs are imagenry imaginary mental objects), therefore we will call it Imaginary Mental Object or [[iMO]], while the objects obtained from phenomenological intervals will call Sensory Mental Objects([[sMO]]). For instance, when the ancient looked upward and saw the sun travels through the skies, the where puzzled. The knew that every object that is traveling need something to pull or to thrust it, yet the sun seems to move without a mover. To solve it, they invented a "story" or a mental object that was missing. They told their hearers that the sun is pulled by invisible horses. The invisible horses where their iMO that bridged the gap. We use iMOs more then we recognize naturally. All our theories and especially the scientific theories are built of networks of iMOs. We only seldom see directly our iMOs. For instance iMO:atoms was [http://en.wikipedia.org/wiki/Atomic_theory#Early_modern_development talked about for more then 200 years in the modern science]. yet not until recently people observed atoms. And even today when we "see" atoms it is through very complicated theories constucted into the scientific observation tools. We cannot observe atoms directly.
