planck scale is the theoretical limit to disassembly.
- Noaidi 3mo agoIf something cannot be reduced, does it exist as an entity?
- rolph 3mo agosomething 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?
- Noaidi 3mo agoMaybe 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.
- rolph 3mo agoyou 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.
- eggn00dles 3mo agoits only the limit we can probe things. just because we can’t measure something doesnt mean nature cant operate at that scale
- rolph 3mo agoactually the idea is that nature cant operate at that scale. the thing about planck units is they are extrapolations that end at single planck length that has some problems just with basic geometry, as well as a supposed instability of a planck space spontaneously collapsing. a planck unit volume must take a form that has dimensions of single planck units and pack together so that no smaller spacings are created. it cant be a sphere, at best it can be some sort of riemannian tetrahedron or triangle. it would be conveinient if that level was a 2D plane, but it still has issues.
- eggn00dles 3mo agoprobe something smaller than a planck unit and nature operates by creating a black hole
- rolph 3mo agothere is no smaller than a planck unit.
- eggn00dles 3mo agoif you want to ignore general relativity or pretend black holes dont exist, sure.
- rolph 3mo agoif 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
