I believe the answer is:
'omnipresence' is the definition.
(I know that omnipresence can be written as ubiquity)
This is the entire clue.
(Other definitions for ubiquity that I've seen before include "State of being (or seeming to be) everywhere at once" , "all over the place" , "Existence everywhere at the same time" , "Universality" , "appearing everywhere" .)
