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?
 Something like 'sci.physics.research' does not seem
to say much to me like 'I am a moderated usenet group'.

Just going over there the group looks like it has a
tiny number of posts.  Nonetheless I have not noticed
any of them saying something like:
Robert Wise, Julian Blaustein, Edmund H. North, and
Harry Bates were not real people but they were just
pseudonyms for someone else.
So who knows.
