Why shouldn't we think of the Uncertainty Principle as just a statement

Is there some experiment that settles "uncertainty" as something "really

You might want to try posting to the moderated group
sci.physics.research , which has some knowledgeable
readers.

You know there is a lot to be said against censorship,
but when it comes to how it is easier for people to just
make stuff up rather than find out the truth (like no
red shift of galaxies) then I guess I could look (maybe
it is impossible to post there).

It should be in the group description if that is available
in your newsreader.

Or I generally figure out a group is moderated after I
post to it and the post does not show up right away
when I retrieve headers.

Or you could look at
https://groups.google.com/g/sci.physics.research/about
which states that it is moderated.
