The question is not whether confirmation of such a theory entails the existence of other universes, but whether the confirmation of such a theory is evidence of other universes.<BR/><BR/>In Bayesian probability, if a theoretical hypothesis, with some prior probability, entails some eventuality, and if that eventuality is observed, then the probability of the hypothesis being true increases.Gordon McCabehttps://www.blogger.com/profile/09151162643523937086noreply@blogger.comtag:blogger.com,1999:blog-37936507.post-4589696139296420392008-12-08T08:58:00.000+00:002008-12-08T08:58:00.000+00:00The answer to the first question is clearly No. If...The answer to the first question is clearly No. If A implies B, it does not follow that B implies A.<BR/><BR/>We do know however, that if B is shown to be false, then it follows that so is A.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-37936507.post-38887303951829774102008-12-07T17:13:00.000+00:002008-12-07T17:13:00.000+00:00goodness me, this is a hard blog to follow...ill h...goodness me, this is a hard blog to follow...ill have another glass of Sunday lunch wine and give it a go!<BR/><BR/>.........Teg person fella, sounds right to me, from what I know about set theory (very little) we don't just have infinite's, but infinite's, infinite's, therefore Math is giving us a good guide to probability, regardless of what the physics says or believes. <BR/><BR/>I suspect that out of absolute chaos comes certain order, by which I mean if I had a million dice, and had infinite throws and time, i can guarantee that at some point i will throw a straight million, million sixes, straight off the bat, its certain, it has to be.<BR/><BR/>Given that, in a years ahead, when I close my eyes and my wife kisses me goodbye, i can think with some certainty that we will indeed be together again. This seems to me to be gods gift to us, certainty realised through uncertainty? so the answer is both.<BR/><BR/>Well it makes sense to me anyway :0)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-37936507.post-67038112717011483592008-12-07T16:06:00.000+00:002008-12-07T16:06:00.000+00:00Theories which are true are generally considered t...Theories which are true are generally considered to be better than theories which are false, hence if our universe actually was created by an intelligent agency in another universe, then a theory which incorporates that fact would be better than one which suggests otherwise.<BR/><BR/>However, it's certainly true that such an explanation begs for a further explanation of how the other universe exists. Ultimately, you either have an infinite regress, or at some point you reach something whose existence is logically necessary.<BR/><BR/>For example, one could adopt Max Tegmark's proposal that all mathematical structures physically exist. There is, one can propose, only one type of existence: absence of contradiction. What we deem the physical universe is simply one particular mathematical structure, which exists by virtue of being free from contradiction. All other mathematical structures exist, but only those containing cognitive self-aware substructures possess observers capable of asking what the mathematical structure of their universe is.Gordon McCabehttps://www.blogger.com/profile/09151162643523937086noreply@blogger.comtag:blogger.com,1999:blog-37936507.post-22292792300258999472008-12-07T15:31:00.000+00:002008-12-07T15:31:00.000+00:00The simulation and experiment theories strike me a...The simulation and experiment theories strike me as silly, because you've just swished the dirt around, replacing "why does our Universe exist and have self-aware life" with "why does that other Universe exist and have self-aware life".
