We cannot see such small particles anything the size of an electron or smaller would not be seen and could be classed as not there or nothing, even if the enclosed space contained many of them.

This is not possible, neutrinos would still be able to pass through whatever cotainer you had.

Even if you pump every molecule of air out of a glass-enclosed spherical space, the volume is filled with a sea of particles, such as electrons and positrons, that come into existence for a tiny fraction of a second. Also, the volume is populated by photons, including electromagnetic radiation left over from the big bang. Even the deepest corners of intergalactic space (space between galaxies) is populated by a little hydrogen.

A perfect vacuum is only a concept, not a reality. No different from a circle. Who's ever seen a *perfect* circle? I bet one of the sides was wobbly, if you look close enough. ;)

merely a question. what of time? time is an ever progressing continuum that, as far as our knowledge serves, encompasses everything. where is time found?

nothing is left, you are reading far too much into a very easy concept. There is empty space in between molecules where there is nothing. Of course there are always quantum fluctuations.

yes, but please open you mind, is that possible? to have a perfect vacuum? i am asking, what is left when there is nothing?

that would be the definition of a perfect vacuum.
