And one of those endpoints is just where the trouble lies. I still
don't get what you meant by "before it possibly could have". I can't
address a potential paradox if I don't understand the terms and
context...

Um, singularities pop up in all kinds of places. Perfectly ordinary
linear algebra goes nuts if you try to divide by zero, frinst.

It's not unique to you. Trouble is it makes our point of view
"special" in that it looks like expansion in all directions from here,
which would put us at the approximate center of the contraction, and
that goes against the Cosmological principle. It's really difficult to
demonstrate one way or the other without doing some observations from
many many AU from here in order to see any anisotropy.

Nature cannot support paradoxes; it's always self-consistent. Our
interpretations can be paradoxical if their basic assumptions are
mutually exclusive.

Hold it. Where do you get the information to model, by watching a
Geiger counter or whatever for a while?
Sorry, I should have been more clear. I meant something more like-
you (or whoever) have done this with several isotopes and have noted
some correlation between their half-lives with some physical property
specific to each isotope that fits the data you have taken. You have
constructed a (probably mathematical) model that describes that
correlation. But, you don't know that C14 exists. I describe its
structure, energy levels, and so on to you but say nothing about its
half-life. I ask you to plug that data into your model, grind the
crank, and predict its half-life. Then, we'd *measure* its half-life
in order to confirm or falsify the model. Mind you, you (or whoever)
is a Determinist and will not make use of probability theory in any
form.
Specific isotopes *have* different specific half-lives. Why? I've
never heard of such a model, deterministic *or* probabilistic. (I
chose this problem specifically to show that determinism simply
doesn't work in many real physical situations.)

Yes, of course; I didn't think it up alone. I'm a Buddhist, a
natural fan of the Middle Way.
We keep saying that fundamental particles' properties are dualistic;
either positively or negatively charged, but what about neutrons and
quarks? Why are there *three* families of leptonss? How can crystals
with pentagonal/dodecahedral symmetry exist? Mind/body/spirit, anyone?
IMO dualism was entrenched in Western science by Plato with his
Ideals vs. Reals. I don't think Ideals are worth thinking about;
what's verifiably real is what matters to me.

Ordinary math would simply say you're using probabilities, all of
which asymptotically approach unity.

Well, that's what I want. It can't be deterministic, because half-
lives are observed to be probabilistic. Yet it must deterministically
assign a specific half-life value to a specific isotope.
And, it hasn't been shown to exist in standard mathematics.

AIUI chaos goes probabilistic where the trajectories branch.
Nonetheless, your random variable must be a *specific* number,
specific to a given isotope. Since there are many isotopes, there
should be a general form, no? Also, whatever process generates that
variable must be constrained to only produce variables associable with
physically possible isotopes. Got any idea what it would look like?

Sure, but remember you are allowed to examine tables of decay times
in order to construct the model, but must leave some out in order to
confirm the model by observing those left out to see if the model fits
them.

For completeness' sake, here's the "score"-
(1) More Information Needed
(2) I think I killed that one. No "spooky action", no paradox.
(3) I'll call that a tie; I have an argument I find unassailable
(currently) but you decline to engage, as they say in the Navy.
(3a) I think I can claim a win. Causality is never observed to be
violated.
(4) Currently unresolvable due to mass cognitive dissonance.
(5) Superposition is observably real on the very small scale, but real
cats can't participate (de Broglie wavelength too short). No paradox.
(6) Again, Nature is always self-consistent IOW does not support
paradox; our interpretations can though. That's the fault of our
interpretations, not a characteristic of Nature.
Me: 4

Oh. Well, disregard the "score", then. ;>)
