If de Broglie is correct, time becomes a problem. Waves do not exist in the instant that is "now". Waves are spread over time. Frequency and wave length (inverses) disappear when measured in Planck time.
But Planck time is a pure abstraction. It is a useful unit for scientific calculation which bears no practical relevance for direct, lived human experience/observation outside of the "artificial" scientific construct in which it clearly is useful.
The other thing about Planck length (space)/Planck time which is really nasty is that anything "smaller" than its minimalist measure either (1) conceivably doesn't exist; or (2) human observers cannot say whether or not it exists, because anything "smaller" than the Planck measures is undetectable by the human mind.
Not to detract from the superlative genius of Max Planck here, heaven forfend. I only want to point out that in his context/construct, he was "doing" science, not life.
