Tegmark is a well known many worlds advocate and thinks it is true; he thinks that everything that does not violate the laws of physics actually happens and I think he's probably right about that. But Tegmark goes further than that, he thinks everything that does not violate the laws of logic or mathematics does happen, and I'm much more skeptical about that.* *FOR Coulombs law to have a function of 1/ r^3 all you'd need is a universe with 4 spacial dimensions, and If the string theorists are right (a big if) then a universe with 4 spacial dimensions is physically possible, in fact acording to them 10 physical spacial dimension is logically NECESSARY.* *String theory multiverse and many world multiverse having nothing to do with each other my ass! Is it really your contention that string theory is OK with a universe with 10 spacial dimensions and one time dimension but not OK with a universe like this one except that my coin came out heads instead of tails?? * * > but the Many Worlds of MWI have the SAME defining parameters as our > universe* > *There must be some physical principles that are true in every world in the Everett multiverse, but what are they? Does the gravitational constant have to have the same value in every universe that it has here, is the Fine Structure Constant a pure number very close to 1/137 everywhere? I don't know. I'm very confident the second law of thermodynamics is true everywhere, I'm reasonably confident the conservation of electrical charge is true everywhere, but I'm less sure of the conservation of mass energy or angular momentum. From a multiverse point of view some of the things that seem absolutely fundamental to us may be be more like the number planets in our solar system and have nothing to do with anything fundamental. * *> since OUR universe is claimed to be reproduced EXACTLY,* > *If you put a gun to my head I couldn't say what you were trying to say by that.* *> except for the measurements realized in [...]* *Forget measurement! Measurement has nothing to do with the MWI, in fact that is the one and only reason I am a Many Worlds fan, unlike the other quantum interpretations it doesn't have to explain what a measurement is, or a observation, or get mired in pointless consciousness debates. * > Of course, if you set up a situation in which a quantum event is > amplified to give a difference in macroscopic outcomes, such as in > Schrödinger's cat, then you can say that the macroscopic uncertainty has a > quantum origin.

After all the movement of the planets and the ability to make good predictions of where they will be centuries in the future with just a few simple equations are the oddballs, most things are not like that at all, even the movement of comets is vastly more complicated. * > > they simply occur randomly *So I guess you think the universe is not deterministic.

So, can you see changes of one part in 10^500? * *John K Clark * -- You received this message because you are subscribed to the Google Groups "Everything List" group.
