Hey all on the list,

Bruno, I must say, thinking of the UDA. The key assumption is this teleportation business, and wouldn't it really be quite Ockham's Razorish to simply conclude from the entire argument that the correct substitution level is, in principle, not only not knowable, but not achievable, which means:

congratulations, you have found a convincing thought experiment proof that teleportation is impossible in any cases greater than, say, 12 atoms or so (give me a margin of error of about plus/minus 100) ... this is very reminiscent of the way that time travel theorists use some of godel's closed timelike curve (CTC) solutions to einstein's relativity to argue that time travel to the past is possible. The problem is, the furthest back you can go is when you made the CTC, and yet in order to make the CTC, the formal and physical conditions require that you already have to have a time machine. This, of course, leads to paradox, because in order to travel in the time machine in the first place, you have to have had a time machine to use as a kind of mechanism for the whole project.

In the same way, I think, does your ingenious UDA lead not to the conclusion you want it to, (i.e. we are eternal numbers contained in the computation of some infinite computer) but rather the less appealing conclusion that, perhaps, the teleportation required in your entire thought experiment is simply impossible, for much of the same reasons as time travel is impossible.

I don't see the parallel.  Can you spell it out?

It's still an important result, but perhaps not as profound as you think if we admit that the teleportation required in your thought experiment is simply not possibly for purely naturalistic (and therefore not computational, or mechanistic) reasons.

Looking forward to your response,

Dan
