If Bohr performs the two slit experiment and his experimental equipment records which slit the electrons went through, then the equipment becomes entangled with the electrons, and if Bohr looks at those Instruments he becomes entangled with the experimental equipment, and thus he detects no interference pattern. But if the equipment doesn't record which-way information then Bohr will see an interference pattern. A measurement by an intelligent entity can cause entanglement, but so can an infinite number of other things.* *>> If the entire universe became infinite at the same instant the > transformation from nothingness to somethingness occurred then the universe > wouldn't need to expand at all to remain infinite.* > > > *> **You're positing an instantaneous transition from Nothing to Infinite > Something.* > *Even an instantaneous transition from nothing to finite something at T=0 already involves infinity, and if you add one infinity to another infinity you still end up with the same infinity. But for all we know there might not even be a T= 0, maybe the universe is cyclical, or maybe the big bang was just the start of our little out-of-the-way corner of the multiverse. Nobody knows, someday we might know but it won't be because somebody was sitting in a comfortable chair thinking about philosophy. If you really want to solve the most profound questions you're going to need to get your hands dirty and perform some experiments. * *>> The universe could be temporally finite but spatially infinite, or > spatially finite but temporally infinite, or both could be infinite, or > neither could be infinite.

There is only one dimension of time but three dimensions of space, and time has a direction but space does not, and at least in big bang cosmology, time is infinite in one direction but not in the other. * *> I didn't claim the universe is infinite.

And that would be true regardless of if space is infinite or finite. And you did say "I see time evolving as space evolves".* > > *Moreover, IF our bubble is finite, which I tend to believe,* > *Everybody believes the observable universe is finite. * *> since it can be enclosed by a sphere of finite radius, I concluded it > can't be flat, since that implies infinite in spatial extent.* > *NO. **The finite observable universe can be contained in a finite sphere regardless of what the shape of the entire universe is. * * > But if we believe the unobservable part came into existence during > Inflation,* > *Long before anybody came up with the idea of cosmological inflation, everybody believed there must be parts of the universe, perhaps very big parts perhaps infinitely big parts, that we will never be able to see because light moves at a finite speed and the big bang happened a finite number of years ago, and nobody believed that the Earth really was the center of the universe. * John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis> qqv -- You received this message because you are subscribed to the Google Groups "Everything List" group.
