Re: Proof that QTI is false
Yes, I agree that you could still have some form of QTI if there are only a finite number of states. I just don't believe in it, because I don't think the use of the relative measure is justified in case the observer isn't conserved. In all other case the absolute measure and the relative measure lead to the same predictions. > > Actually, in standard quantum mechanics, there is an infinity of > observer moments, 2^{\aleph_0} of them in fact. > > What you are talking about are various quantum gravity theories, such > as string theory, which appear to have a finite number of observer > moments. > > However, even if as observers we are locked into a Nietschian cycle at > some point in time due to finiteness of the number of possible states, > the number will be so large that the practical effects of QTI will > still need to be considered. > > Cheers > - Original Message - From: "Russell Standish" <[EMAIL PROTECTED]> To: Sent: Wednesday, September 13, 2006 4:31 AM Subject: Re: Proof that QTI is false > On Tue, Sep 12, 2006 at 11:58:14PM +0200, Saibal Mitra wrote: > > > > QTI in the way defined in this list contradicts quantum mechanics.

What happens is that if there are only a finite number of quantum states there is one which has the smallest non zero probability.

Another way is probabilitistic assignment, where a value of 0.3 has a 70% chance of being mapped to 0 and 30% chance of being mapped to 1. See my paper "Population models with Random Embryologies as a Paradigm for Evolution" Complexity International, 2 (1994). Of course these two possibilities do not exhaust the space!

Re: Proof that QTI is false
Actually, in standard quantum mechanics, there is an infinity of observer moments, 2^{\aleph_0} of them in fact. What you are talking about are various quantum gravity theories, such as string theory, which appear to have a finite number of observer moments. However, even if as observers we are locked into a Nietschian cycle at some point in time due to finiteness of the number of possible states, the number will be so large that the practical effects of QTI will still need to be considered.

Whether or not this is the case, it is a secondary issue to my question re *survivability* (call this the Quantum Theory of Enhanced Personal Survivability, or QTEPS) which is based on the '1st-person pruning' of non-conscious branches of MW. My question to Russell and the list is whether this actually influences real-life behaviour - i.e. is anyone in practice saying 'yes' to this doctor?

Proof that QTI is false
QTI in the way defined in this list contradicts quantum mechanics. The observable part of the universe can only be in a finite number of quantum states. So, it can only harbor a finite number of observer moments or experiences a person can have, see here for details: http://arxiv.org/abs/gr-qc/0102010 If there can only be a finite number of observer moments you can only experience a finite amount of time.
