If something cannot be reduced, does it exist as an entity?

something that cant be reduced would be the only entity, all other things are assemblages of that entity, the problem of variability occurs, if you can observe at the scale of absolute fundamental structure, how can difference occur?

Maybe it’s not the thing that is different, maybe it’s our minds that create difference?

And by difference, I mean, establish boundaries between objects.

you suggesting that there is a continuity of spacetime rather than a pixelation, which is perfectly valid, the whole problem with planck units is that they are extrapolations, just like the infinity or the point particle, they are mathematical extremes.

the geometric structure of spacetime at planck scale is problematic, considering how you might visualise a planck polyhedron so that no space is defined in less than whole planck units i.e. all dimensions of length are whole numbers.

you have to do some topological trickery to make a discreet planck volume that works.

its only the limit we can probe things. just because we can’t measure something doesnt mean nature cant operate at that scale

[delayed]

probe something smaller than a planck unit and nature operates by creating a black hole

there is no smaller than a planck unit.

if you want to ignore general relativity or pretend black holes dont exist, sure.

if you want to ignore the maximum energy content of space below schwarzchild radius of one planck length go ahead, there is no curvature that will bend space that tightly, and GR doesnt apply at that level
