Dear SE Grimm
A general concern regarding any theory based upon a smallest particle or space: How can a theory that is limited to one slice of reality, say the Planck scale, determine and define the actions at the atomic scale (it should explain this), at the molecular scale (it can do some of this), at the macro-molecular and protein level, at the cellular level, at the ligament and tissue level, at the organ level, at the human body level, at the meteorological and planetary climate level, at the solar, black hole and solar system level, at the galactic level, at the galaxy cluster level?
How can any theory limited to just one slice of this continuum of scale expect to describe and determine the actions and interactions at all these levels?
If you divide up space at, say, the Plank scale, how does this transpose to our scale or to that of stars or galaxies? The proposal is that all space is either divided up only at this tiny scale, or the universe exists only as tiny particles - even when this is not our experience.
How are we to explain, at only the Planck level, the changes in a beach ball rolling down a dune and scuffing on a rock? The (macro) actions are easiest to describe at the level of the beach ball not the Planck level. Do we eschew the simpler explanation for a very difficult and poor explanation of these events? Why would we not expect to have a theory that works at all these levels - especially across these levels, since we experience actions that cross these levels?
We are measuring the universe in thin slices, like measuring only in the plane of Flatland when the universe is three-dimensional.
We have lost sight of what we are attempting to describe (all reality at all scales) - which is likely due to limitations in our tools (mathematical as well as measurement). Without admitting and addressing these limitations, we are going down a rabbit hole.
We need new tools.
