I've yet to see anyone change their mind on something due to a Hilbert's Hotel argument, or even show the slightest effort of trying to.
You might be expecting a little bit too much there. I do agree with you, as I think some arguments that were brought up here should have been enough to convince people as far as that they are believing 'wrong' things, however I've come to learn here that it's not (always) the facts that
really matter.
Also, the main problem of course is 'science & evidence' vs. 'religion & faith', so to speak. This is a simplified representation of what's going on of course.
However, as a result.. people's minds won't change in here,
Cheers
