No, you cannot identify a state of nothing in our present Universe. You can fudge and make axiomatic that anything below Planck lengtha nd Planck time is not real, but that is not the same as defining a state of nothing. In fact, Haisch, Rueda, and Puthoff have derived F = ma using quantum parton configurations, thus showing that inertia is due to real ‘things’ smaller than quarks acting upon quarks.
The cool thing is that nothing isn't nothing any more. Science is changing our understanding of nothing to the point that what we considered nothing prior actually has a lot of something. In quantum fluctuation we can see particles popping in and out of existence in fields of "nothing" all the time.
