This is not to say that they are equivalent concepts on a
fundamental level - that would be silly for anyone to assert
that,, rather I'm speaking that the way that people REACT to
comprehension of either Trinity concept or QM concepts is
similar.
The understanding in either case is not verifiable by experiment
and in both cases when they speak of it, there's almost a
starry-eyed "mystical experience" quality to it.
I find that point, where people leave the realm of "This is
reasonable" and go into the realm of, "I get it, but I'm going
to sound strange if I try to explain it to you in a way you
understand it" quite fascinating, in whatever field people are
in.
