You need instrumentation to zoom in. Is it fingers in a vacuum? You’ll probably find air molecules but you don’t need to zoom to know that.
If it’s a vacuum, you’ll find the backdrop of the microscope slide area.
Measuring living tissue is no easy feat. You can zoom in to tissue using lots of tricks but the gaps inbetween living fingers, I doubt there’s much you’ll find of anything.
There’s little scientifically that you can find between fingers.
You can find air.
MAYBE you can find coulomb force — MAYBE but I’d need to see that.
Following Wittgenstein’s general principle about using common word meanings and not specialized ones,
a break or hole in an object or between two objects.
an unfilled space or interval; a break in continuity.
a difference, especially an undesirable one, between two views or situations.
To flesh gap further as a concept: Synonyms:
chasm, crack, cut, difference, disagreement, disparity, divergence, divide, division, hole, inconsistency, rift, void, aperture, arroyo, blank, caesura, canyon, cleft, clove, cranny, crevice, defile, discontinuity, fracture, gorge, gulch, gully, hiatus, hollow, interlude, intermission, interruption, interstice, interval, lacuna, lull, notch, opening, orifice, pause, ravine, recess, rent, respite, rest, rupture, separation, slit, slot, space, vacuity, interspace
So: Can you say that none of these common senses of what “gap” means is suitable to describe what is inbetween fingers?
I’m actually ok with that BUT you’d ALSO have to deny the reality of a thing called “fingers”.
For: if there is no “inbetween”, no break in continuity, all is continuous and there is no distinction.
NOTE: I want to be wrong. So if you can do that, that would be great.
Question: Let’s suppose you’re at the beyond microscopic level and at the subatomic level.
Floating around in all that vacuum energy, ducking quantum foam flips and mini quantum gravity spikes.
You travel for thousands of years to finally reach what the macro world would call “a finger”.
What then? Is it: a) More of the same or b) Something not the same?
If it’s not the same, what were you in before?
It’s still THING – NOT THING – THING or : A B A. B is gap between A. Discontinuity.
If you have “two” of a thing, there is a gap. Otherwise, there’s just one thing.
