Yes but only when you look at the radioactive isotopes of potassium ; I don't
know about you but I haven't done that in, gee, it must have been days.

But what about far more numerous places we haven't looked?

Is there any reason to think that our world contains no contradictions?
We probably wouldn't recognize such a thing anyway, we'd just say
there must be some new physical law we don't understand yet, or call it
another manifestation of quantum weirdness.

I don't think that's true but even if it is so what, that's it's problem not ours.

True beyond doubt, but maybe magic exists. And you're right, we probably face a
Dysonian end-game and not the sort of climax to the universe Tipler describes,
but there might not be any deep logical reason for that, it could be pure chance,
such as the fact that 9 planets circle the sun. There is nothing special about the
number 9, other stars have a different number of planets and perhaps other
universes are closed making infinite computation possible.
