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).

Basic question, is there some way to tell whether a
usenet group is moderated or not moderated?

 Search for "physics moderated".

Thank you.  I found one part of the topology of the
site that showed something like 'copyright 2025'
rather than 10 or 20 years ago.
A lot of people are attracted to the bells and
whistles of the other sites and do not notice
or care about the censored part.  They might
be able to sign up to post and read or maybe not.
I guess usenet is older than the world wide web
or internet.
It seems to me like it is used less than it
did 10 or 20 years ago.  It is very ancient.
