Well you know they came up with the idea that
'particles and waves' were something different from
'points and curves' back then so that they could
be unclear but then (imply) that they were not
speaking gibberish.
But.
If there are not an infinite possibility of
fine partial transfers of a 'photon' of light
at different 'frequencies' or 'wavelengths'
of the light (there is some description of
fine space and time in a 'waveform') [keeping
it simple a 'photon' would be an increment of
energy or momentum transfer] then if it either
happens or it does not then thatis 'uncertain'.
I am thinking that is generally describing the
circumstances of the principle.

Space and time itself are mathematical dimensions against
which all other measurements are taken.
'Quantizing' that would destroy the basis for measurement.
That would be a mathematical version of 'gibberish'.
