Part 1
Fields of attraction relate pokeballs to pokemon since pokeballs actually are made by culling a certain type of pokemon created to manipulate matter. Once it is correctly processed, a pokeball bears relation to all pokemon on a molecular level through genetic datasets. The pokemon which the the pokeball is made from processing acts as a gravitational singularity in this regard. The physical location of the pokemon "captured" is then displaced by an acceleration of its material constitution rushing in toward the core of the ball, approaching the speed of light known as the "return" which converts the physical particles into pure energy. This energy remains in constant motion through the use of a "center" which maintains a wobbling rotation pattern within the ball allowing for time to pass extraordinary quickly inside. Taking a pokeball to a poke center allows for this process to be further amplified by use of a particle beam and "heal" the creature through artificially created time manipulation. Of course, from the perspective of the pokemon, minimal time has passed since it was sent into the ether - its body and brain both turned into raw energy by the pokeball's attractive tidal force. In truly rare circumstances a "reset" can be attempted to save a dying pokemon, but it always loses its memories in the process raising a number of philosophical questions surrounding consciousness.
