Psychic friends network? Ouija board? Frog entrails? Oh.... I get it, lots and lots more money so they can 'think' big thoughts about how insignificant our universe really is in the 'greater scheme' of things. Sigh. <br /><br /> There really is an easier (and much cheaper) way. Physicists who want to pursue the multiverse meme need to put down the physics books and read lots of fantasy novels until they overdose and want to puke. Each and every one of these books take place in another multiverse according to their own statements about an infinite number of different universes with different laws of physics... <br /><br /> Or... we could start mandatory drug testing of all physicists and scientists who receive government funding. So much coming out of academia has the haze like tinge of pot induced fantasy.CFTnoreply@blogger.comtag:blogger.com,1999:blog-8148573551417578681.post-25457891592905290492019-01-29T00:00:44.307-08:002019-01-29T00:00:44.307-08:00Zeno was trying to illustrate how poorly conceived...Zeno was trying to illustrate how poorly conceived arguments lead to nonsense. Employing infinity in an argument magically interacting with finite time or movement is utterly meaningless, as time and all movement is finite in measurable observation. Pretending you can do anything forever is a good way to get nowhere and accomplish nothing very unscientifically. <br /><br />CFTnoreply@blogger.comtag:blogger.com,1999:blog-8148573551417578681.post-92089478581984977072019-01-28T07:47:22.661-08:002019-01-28T07:47:22.661-08:00Right but motion is still not explained.

The problem with the paradox is that it isn't a paradox at all, it's a logical error of assumptions leading to impossible consequences. If you cross half way across the room, then half of that distance, then half of that etc, you never reach the other side of the room, logically it would seem, except that you have already revealed the contradiction in the premise itself, you crossed half the room, thereby proving movement is already finitely possible regardless of any other silly abstractions you layer on top of it , No distance ever travelled has anything to do with infinity, as any infinity is a purely numerical ABSTRACTION outside of time, and a measureable distance (like crossing a room)is a finite reality within time.

Look all you want in the entire universe, you will never actually discover a '1', or a n + 1 anywhere, just various symbols which represent the abstraction. Nothing in nature works by math being done with numbers, or involving calculations, these are merely the synthetic tools humans have developed to measure, model, and describe aspects of reality we have the ability to measure, the reality itself is NOT math. <br /><br /> The only ridiculous reason Greene has for pandering infinities is that he is unable to mentally deal with the actual improbability of his own existence (its an existential crisis of sorts). He simply can not deal with the sheer fact that when you apply a statistical likelihood of even being alive against the largely inert immensity of the tiny fraction of creation we have been able to observe, it is very statistically improbable bordering on miraculous of the random chances of such an event even being possible within a mere 14 billion years, so he attempts to deflect this numerical improbability by whistling up a literal infinite chorus of other universes to deflect the numerical improbability of his own unique existence into a mind numbing infinite number of universes. Greene needs to believe in randomness and mindless probability determining all outcomes in his world view, but alas, even by his own calculations, the observable universe indicates otherwise.<br /><br /><br />Mathematicians are just as prone to self delusion as anyone else when confronted with what they don't want to accept, and mathematicians are also historically notorious card cheats, stacking the deck whenever they don't like the odds.

Solomon Feferman has written a somewhat technical book on how transfinite mathematics is hogwash: "In his concluding chapters, Feferman uses tools from the special part of logic called proof theory to explain how the vast part--if not all--of scientifically applicable mathematics can be justified on the basis of purely arithmetical principles. At least to that extent, the question raised in two of the essays of the volume, Is Cantor Necessary?, is answered with a resounding no."<br />https://www.amazon.com/Light-Logic-Computation-Philosophy/dp/0195080300 <br /><br />Ultrafinists or strict finitists simply don't make silly assumption and they avoid the whole mess. A completed infinity is an immediate self-contradiction. Impredicative definitions are logical contradictions. From this you get "paradoxes" like Banach-Tarski or uncomputable numbers etc. Pure baloney and a waste of time.MD Coryhttps://www.blogger.com/profile/05342743632013663077noreply@blogger.comtag:blogger.com,1999:blog-8148573551417578681.post-9756308790767463492019-01-26T18:33:54.347-08:002019-01-26T18:33:54.347-08:00Yes, almost all the paradoxes of mathematics have ...Yes, almost all the paradoxes of mathematics have to do with impredicative definitions or infinity. Strict finitists suffer no mysteries at all. However, the problem with mathematics modeling physics was apparent with Zeno quite a long time before any of these derivative topics. The paradoxes Zeno described have never really been answered by math. Joseph Mazur pointed this out in his book "The Motion Paradox: The 2,500-Year Old Puzzle Behind All the Mysteries of Time and Space." Zeno never received a proper answer. The nature of the mathematical continuum (false dichotomy of infinite discreteness vs discreteness) says nothing about physics. It's just circularity and invalid logic at that.<br /><br />My point about "nonlocality" (not signal nonlocality) is that people who reject it are engaging in mysticism. We have deterministic accounts, however much you might not like them for aesthetic reasons. I'm not sure people who try to change logic or blur our thinking with Copenhagen are any less mystical. If you like QM, you are still stuck with it violating Bell. You can debate this all you like but I have read the papers and Bell was following EPR and not making assumptions about classicality, realism, counterfactuals, etc.MD Coryhttps://www.blogger.com/profile/05342743632013663077noreply@blogger.comtag:blogger.com,1999:blog-8148573551417578681.post-81651561033496708122019-01-25T12:15:21.565-08:002019-01-25T12:15:21.565-08:00Yes!

If, for the sake of argument, against your very reasonable and to me agreeable idea that we as people can only construct models that have a finite number of components, infinite detail (countable or uncountable) is in fact required to specify one real object, then the combinatorics of possible real objects would require the number of universes to be a higher order of infinity for there to be even one copy. Dividing and multiplying and exponentiating infinities is not a decent game even for physicists.Peterhttps://www.blogger.com/profile/08654675777726560464noreply@blogger.com
