@Brent. The only thing that you ever observe is your own consciousness. Which undoubtedly does a great job at tricking you into believing that you observe an "external world". The only trick here is your usual one; thinking you've written something useful.

Nobody knows what will happen when things get super small because our two best physical theories, Quantum Mechanics and General Relativity, disagree with each other. Most believe that something will prevent a zero volume from ever occurring, but nobody knows what that "something" is. * *John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* Maybe it's a 5th force. What I'd like to know is this; assuming an infinite spatial universe and that it gets very very small as we run the clock backward, the observable regions shrinks, but what happens to the unobservable region? Quentin claimed to have an answer, but I can't recall what it was. AG All theories treat the unobservable regions as being similar to the observable (what else could you justify?). So every finite region, observable or not shrinks to zero. Brent -- You received this message because you are subscribed to the Google Groups "Everything List" group.
