True.  But there always is a truth that is not provable (given the
system).
And you can find out more about it by changing the system and comparing
results.

By the way, you never answered my question, what are we trying to do on
the Everything List besides logical inference given a system?  My take
is that at least part of what we are doing is banging systems against
each other via discussion.  If this is not productive, then we should
abandon the Everything List and buy telescopes.
