A space void of anything -known or unknown yet to us- is (philosophically) a non sense, because a 100% void is inexisistent and consequently cannot exist, there being nothing to exist; this energy may be manifested in an infinity of forms, some of whom may be detectable by us, while others, not. Limiting the amount of available forms of energies to few,(gravitational, electromagnetic, etc.) do not make sense, this number being the reflection of our present knowledge, which can be far away from reality, if reality exist.
However, if in different locations at different times (assuming that we can monitor different locations and times), this named energy is actting in a similar manner (following the same rules) then the problem is far more complex, implying either comunication and/or a common source. If this is true, then may be the other name for this energy field will be God (not in any religious sense).
