imperceptibility
State of being unnoticeable
Imperceptibility is the quality of being impossible or nearly impossible to perceive.
Something with imperceptibility escapes notice by the senses or the mind: The imperceptibility of the change made it hard to document.
The word often describes gradual processes—erosion, aging, shifts in opinion—that occur too slowly to observe directly.
