Superposition of states on a same universe are a bit hard to swallow. I think people reject the idea of a multiverse because it sounds loony, but my understanding is that making QM consistent with a single universe requires magical thinking. It's the same as saying that consciousness emerges from neural activity. People overlook the magical step because they are more confortable with the resulting model. > > Bruno > > > > So no problem. > > ----- Receiving the following content ----- > *From:* Telmo Menezes <[email protected]> > *Receiver:* everything-list <[email protected]> > *Time:* 2013-01-31, 08:13:30 > *Subject:* Re: Re: About the Infinite Repetition of Histories in Space > > Hi Roger, > > In the one universe model, where does the extra computational power of > quantum computers come from? > > > On Thu, Jan 31, 2013 at 2:09 PM, Roger Clough <[email protected]> wrote: > >> Hi Telmo Menezes >> IMHO more than one universe is unjustified. >> >> ----- Receiving the following content ----- >> *From:* Telmo Menezes <[email protected]> >> *Receiver:* everything-list <[email protected]> >> *Time:* 2013-01-30, 12:10:08 >> *Subject:* Re: About the Infinite Repetition of Histories in Space >> >> Hi Roger, >> >> I find it harder to believe in finite universes.
