Physics and the actual infinite (simplified) About Galileo and about the infinite After Archimedes, Galilei Galileo applied mathematics to physics. Alexandre Koyré wrote in "D'un monde clos à l'univers infini" that Galileo threw Earth in the Sky. For almost all ancient greeks, the Earth and the Sky were not connected and mathematics applied only to the Sky. Nowadays, scientists and philosophers think that the actual infinite cannot be applied in physics. So now is the time for furthering of Galileo of applying mathematics to physics. Establishing a link between the actual infinite and the Big Bang is furthering the insight of Galileo. The physical space is infinite because in assuming so, you can understand why the Big Bang occured. It is because space vanished as is applied the negation of the mathematical axiom of choice to describe space. It is difficult to imagine the contained without the containing, but it is what happened because space is infinte in the Big Crunch followed by the Big Bang. There was always an universe (in a sequence of universes). It is not clear whether this theory is confirmed or not as I publish in "The bulletin of symbolic logic" but without any feedback and I am not quoted.

I am asked by Klaynos "how about with maths ?" : An interpretation about space and time in quantum mechanics There was a repeated experiment where at first, two protons are joined and of opposite spins. Then, the second is taken far away, and it is acted upon the first to modify its spin. The second proton will change its spin to keep it the opposite of the spin of the first. Now, if you will assume with me that we can apply the set theory ZFU to physical space, U (urelements,non sets)) being physical space, you will see that we get an interpretation of the experiment. Indeed, as it is not possible to define a usual distance in U, the second proton will not be any more far away from the first. Also, if we consider time to be U, we cannot say that the protons were separated a long time ago and that there should be no more influence. [...] There was another repeated experiment with a photon, expected to go one way, going both two quite separated ways. Here, again, if we assume something else about space, the two ways would be not that much separated. Regards, Adib Ben-Jebara. One reason why the negation of the axiom of choice is true We apply set theory with urelements (non sets) ZFU to physical space of elementary particles; we consider locations as urelements, elements of U, in number infinite. Ui is a subset of U with number of elements n. XiUi is the infinite cartesian product and a set of paths. Let us consider the set of paths of all elementary particles-locations which number is n. If n is greater than m in CC(2 through m), countable choice for k elements sets k=2 through m, the set of paths will be the void set. So, after an infinite time, physical space would become void, the universe would collapse and a Big Crunch would happen. The matter would have to go somewhere and indeed the Big Bang happened. So, n is indeed greater than m. Let us notice that physical space is infinite. It's rather complicated but what do you think ? Isn't it most likely that the negation of the axiom of choice is true ? It is like the non-euclidian geometry which is known in physics as true. Regards, Adib Ben Jebara.

About every day life of the elementary particles (simplified) This is what I think about some of elementary particles behavior, avoiding much math. The elementary particle jumps from one location to another with the set of locations discontinuous and not linearly ordered. What is far with the standard distance can be near with the jumps. So, two particles can have an action one on the other after having taken a "distance" one from the other. The two particles could be within a limited number of jumps one from the other. Therefore, there could be an unexpected correlation. Time itself is discontinuous and not linearly ordered. So, there are no causality relationships unless time is ordered by the observation set up. Help is welcome for deducing other consequences of this behavior. Adib Ben Jebara. http://www.freewebs.com/adibbenjebara

The Big Crunch will happen after an infinite time The collapse of the universe will happen after an infinite time. For that, a singularity has to happen and I think no space (the void set) must have a part in it. We have seen that time can be infinite in "An idea about time in cosmology" in ASL Annual Meeting 2OO4. We have also seen that space at the level of elementary particles can be described with only a particular case of the axiom of choice holding, countable choice for a family of sets of n elements n=2 through m ,in "About space and time of elementary particles" in ASL Annual Meeting 2005 and in "About space being not a continuum" in Logic Colloquium 2005. No space (the void set) cannot be reached by a finite number of times but by infinite Cartesian products of sets of locations. The void set will be supplemented with particles and it will not be the void set any more but without there being space. Then, it will be again the singularity of the Big Bang which creates space. To explain more, in my view, space is the set U of urelements (non sets) of a Fraenkel Mostowski model and the Big Crunch will occur because of what happens with such a space. The connection between that specific set theory and physical space is my thesis, at the level of elementary particles. The conclusion of the Big Crunch happening holds because bodies are made of elementary particles. The actual infinite means that the Big Crunch will really happen. We have to notice that time can be countable or of the cardinality of the set of urelements U or a continuum, like space can be of the cardinality of U or a continuum, in different cases.

About set theory with urelements and elementary particles Platonists seek a reality in mathematics, associated with the truth of axioms. Logicists and formalists are concerned about consistency and independence of axioms but not about their truth. I suggest, as a Platonist, that the axioms definitely true are those applied to previously unsolved mathematical problems or to physics or social sciences or ethics. For the case of the axiom of choice, I state that the negation of the axiom of choice is true because I apply it to quantum mechanics and cosmology which are part of physics. It is because of the lack of interdisciplinary research that the status of the axiom of choice remains ambiguous. People do not think unity of knowledge a good thing. In XiUi with Ui a set of locations, i does not have to be a count of time. We consider simple sequences of locations. Let S be a finite well ordered subset of U, we can define a distance by counting the number of urelements(non sets) between two urelements. Mr Andreas Blass corrected with number of urelements between two urelements +1. This applies for space and time as well. Mr Andreas Blass pointed out the lack of useful coordinates and that there is no vector space because it would be non denumerable. My idea might insert itself where a reality is out of reach of the usual model. Then, there is the embedding theorem of Sochor and Jech of U in V. Mr Andeas Blass pointed out that the embedding is complicated, involving sets of sets of ordinals. As time as U is not well ordered, except in S above, there are less causality relationships at the level of elementary particles than at our level because causality is based on time ordered.

About experimenting about elementary particles about space and time That ZFU (set theory with urelements, non sets) is applied to space and time explains the correlations between particles (in "An interpretation about space and time in quantum mechanics") in Logic Colloquium 2007. ZFU applied to elementary particles is most likely to explain the Big Bang, see http://www.scienceforums.net/forum/showthread.php?t=30616 As the usual distance is not defined, we consider the distance between particles number of urelements in between + 1 Mr Andreas Blass remarked that if the urelements are ordered by the experiment set up, measurement may vary with the order when the conversion to meters and seconds is made. But it seems to me that , whatever the order of urelements, the number of urelements in between + 1 stay the same. After a comment from Mr Andreas Blass, I feel the need to precise that the first and the last extremities of the sequence are not to be changed as they are associated to particles. I see the order between urelements as a distortion made by the experiment set up. The experiment set ups are so sophisticated that they can detect what exists but that might be with a distortion especially for space and time which are invisible. The experiment set up probably makes a particle move in a straight line. Without the experiment set up, may be the particle moves in approximately a straight line. We can say that we do not know what the particles do by themselves even if we know what they do when we make them appear to us. Mathematics help us see things as they are, without an experiment set up interfering but then experiment set ups are necessary because If mathematics and experiment set ups agree on some thing, then that is where the truth is.

About a distance for elementary particles In "An interpretation about space and time in quantum mechanics" in Logic Colloquium 2007, we have seen that the usual distance is not defined for space and time because we apply the theory ZFU (set theory with urelements, non sets). We explained some correlations between particles. I would have doubts about the assumptions if I did not apply them for space successfully to explain the Big Crunch and the Big Bang in http://adibjebara.blogspot.com/ As time is but another dimension, I apply ZFU to time as well. Now, let U1xU2 be space time with U1 space and U2 time. Many things are discontinuous in quantum mechanics. So, why not space and time ? At the level of elementary particles, space and time are also not linearly ordered. As the experiment set up gives us meters and seconds, that means that the space and time considered by the experiment set up are the space and time at our level. I conjecture that when we measure, we introduce, finitely, order of urelements in U1 and U2, in a laboratory. A distance is number of urelements in between + 1 which is converted to the measurement at our level in meters and seconds. The experiment set up changes much what exists as space and time. The skeptics should be aware that some experiments needed interpretations and I provided them. As a Platonist, I see some reality in Dedekind cardinals and, thus, in ZFU. There is already an experiment where a particle goes both two separate ways. So, its space is different from ours. There remain to find other experiments to detect that locations and times are not linearly ordered. There remains also to comment on the lack of localism. I thank Mr Andereas Blass and Mr Abderazak Abadlia for their comments. Adib Ben Jebara http://jebara.topcities.com

An axiom to settle the continuum hypothesis ? (Logic Colloquium 2004 contributed abstract) Paul Cohen used a set of generic reals to prove the consistency of the negation of the continuum hypothesis with other axioms. It is my opinion that such sets do not really exist for a Platonist. My opinion is that the continuum hypothesis is true. Here is a tentative axiom from me to try to prove it. Axiom : An infinite subset of the power set of N has a bijection either with a countable union of (pair wise disjoint) sets of n elements or with a countable Cartesian products of (pair wise disjoint) sets of n elements. Mr Andreas Blass proved that this axiom is equivalent to the continuum hypothesis. So, the axiom is consistent with the other usual axioms and independent from them, from the works of Kurt Godel and Paul Cohen, respectively. Mr Andreas Blass used the assumption that the Cartesian product is not the empty set but he did not use the axiom of choice. The question which remains is : is it a good axiom ? My opinion is that it is realistic for a Platonist. But may be the axiom is not simple enough and may be a simpler one could be found. Adib Ben Jebara. http://jebara.topcities.com

Mathematics are applied to physics since a long time ago. I apply the negation of the axiom of choice. Adib Ben Jebara.

One reason why the negation of the axiom of choice is true We apply set theory with urelements (non sets) ZFU to physical space of elementary particles; we consider locations as urelements, elements of U, in number infinite. Ui is a subset of U with number of elements n. XiUi is the infinite cartesian product and a set of paths. Let us consider the set of paths of all elementary particles-locations which number is n. If n is greater than m in CC(2 through m), countable choice for k elements sets k=2 through m, the set of paths will be the void set. So, after an infinite time, physical space would become void, the universe would collapse and a Big Crunch would happen. The matter would have to go somewhere and indeed the Big Bang happened. So, n is indeed greater than m. Let us notice that physical space is infinite. It's rather complicated but what do you think ? Isn't it most likely that the negation of the axiom of choice is true ?

How do you know the value is complementary if you don't know it ? Urelements are non sets.

Thank you for remembering the topic, a new idea about space in quantum mechanic. Some posts are very complcated, I wonder if it is necessary that they be so.

We have drifted far from the subject. Why don't you ask for instance if the time needed to reach a Big Crunch is infinite ? It is.
