STRING THEORY AND OUR RELATIONSHIP WITH NATURE: THE CONVERGENCE OF SCIENCE, CURRICULUM THEORY, AND THE ENVIRONMENT by VIRGINIA THERESE BENNETT (Under the Direction of John A. Weaver) ABSTRACT Curriculum Theory affords us the opportunity to examine education from a multitude of directions. This work takes advantage of that opportunity to explore the relationships between science, nature, and curriculum using string theory and our ideas about the environment as a backdrop. Both the energy and multiple possibilities created by strings and the rich history leading up to the theory help to illustrate the many opportunities we have to advance discussions in alternative ways of looking at science. By considering the multiple dimensions inherent in string theory as multiple pathways and interweaving metaphors from Deleuze and Guattari, Michel Serres, and Donna Haraway, our approach to environmental issues and environmental education allow us to include alternative ways of looking at the world.

But these very strides, especially in cosmology, have brought back the old conflict between science and Western religion. The new concepts that are foreign to the Western religion are the concepts of Multiverse, aka Multiple Universes or Parallel Worlds, and the birth of the Universe from Nothing (Vacuum) by quantum fluctuations (randomness, by chance). These two concepts go against the basic tenants of Western religion favouring a unique Universe. In this article we show that there is no such conflict between these concepts of modern cosmology and ancient eastern philosophies and religion.

    Dr. Michio Kaku Dr. Michio Kaku is one of the most widely recognized figures in science in the world today. He is an internationally recognized authority in two areas. The first is Einstein’s unified field theory, which Kaku is attempting to complete. The other is to predict trends affecting business, commerce and finance based on the latest research in science. Kaku holds the Henry Semat Chair in Theoretical Physics at the City University of New York. He graduated from Harvard University in 1968 (summa cum laude and 1st in his physics class). He received his Ph.D. in physics from the University of California at Berkeley in 1972 and has been a professor at CUNY for almost 30 years. He has taught at Harvard and Princeton as well. His goal is the complete Einstein’s dream of a “theory of everything,” to derive an equation, perhaps no more than one inch long, which will summarize all the physical laws of the universe. He is the co- founder of string theory, a major branch of string theory, which is the leading candidate today for the theory of everything. His Ph.D. level textbooks are required reading at many of the world’s leading physics laboratories. He is the author of several international best sellers. He has two New York Times best sellers, Physics of the Future and Physics of the Impossible. Other books include Hyperspace and Visions: How Science Will Revolutionize the 21st Century. For Physics of the Future, he interviewed 300 of the world’s top scientists, many of them Nobel Laureates and directors of the largest scientific laboratories, about their vision for the next 20 to 100 years in computers, robotics, biotechnology, space travel, etc.

  • The Many-Worlds Interpretation of Quantum ENTERPRISES/RGA MIRAGE Mechanics
    Vol 448|5 July 2007 COMMENTARY Many lives in many worlds Accepting quantum physics to be universally true, argues Max Tegmark, means that you should also believe in parallel universes. lmost all of my colleagues have an opin- ion about it, but almost none of them Ahave read it. The first draft of Hugh Everett’s PhD thesis, the shortened official version of which celebrates its 50th birthday this year, is buried in the out-of-print book The Many-Worlds Interpretation of Quantum ENTERPRISES/RGA MIRAGE Mechanics. I remember my excitement on finding it in a small Berkeley book store back in grad school, and still view it as one of the most brilliant texts I’ve ever read. By the time Everett started his graduate work with John Archibald Wheeler at Prin- ceton University in New Jersey quantum mechanics had chalked up stunning suc- cesses in explaining the atomic realm, yet debate raged on as to what its mathematical formalism really meant. I was fortunate to get to discuss quantum mechanics with Wheeler during my postdoctorate years in Princeton, but never had the chance to meet Everett. Quantum mechanics specifies the state of the Universe not in classical terms, such as the positions and velocities of all particles, but in terms of a mathematical object called a Is it only in fiction that we can experience parallel lives?

  • Multiverse Sanjaya Baral and Dhurba Chhetri St
    Multiverse Sanjaya Baral and Dhurba Chhetri St. Xavier’s College, Maitighar, Kathmandu, Nepal Abstract: Multiverse scenarios in cosmology assume that other universes exist "beyond" our own universe. They are an exciting challenge both for empirical and theoretical research as well as for philosophy of science. They could be necessary to understand why the big bang occurred, why (some of) the laws of nature and the values of certain physical constants are the way they are, and why there is an arrow of time. This essay clarifies competing notions of "universe" and "multiverse"; it proposes a classification of different multiverse types according to various aspects how the universes are or are not separated from each other; it reviews the main reasons for assuming the existence of other universes: empirical evidence, theoretical explanation, and philosophical arguments. Keywords: Big bang, universe, multiverse, cosmic inflation, time, quantum gravity, string theory, laws of nature, physical constants, fine- tuning, anthropic principle, philosophy of science, metaphysics, falsifications 1. INTRODUCTION include Stephen Hawking, Steven Weinberg, Brian The multiverse (or meta-universe) is the hypothetical Greene, Max Tegmark, Alan Guth, Andrei Linde, set of infinite or finite possible universes (including Michio Kaku, David Deutsch, Leonard Susskind, the universe we consistently experience) that Raj Pathria, Sean Carroll, Alex Vilenkin,Laura together comprise everything that exists: the Mersini-Houghton, and Neil deGrasse Tyson.

  • Many-Worlds Interpretation of Quantum Mechanics: a Paradoxical Picture
    [math-ph] Many-Worlds Interpretation of Quantum Mechanics: A Paradoxical Picture Amir Abbass Varshovi∗ Faculty of Mathematics and Statistics, Department of Applied Mathematics and Computer Science, University of Isfahan, Isfahan, IRAN. School of Mathematics, Institute for Research in Fundamental Sciences (IPM), P.O. Box: 19395-5746, Tehran, IRAN. Abstract: The many-worlds interpretation (MWI) of quantum mechanics is studied from an unprecedented ontological perspective based on the reality of (semi-) deterministic parallel worlds in the interpretation. It is demonstrated that with thanks to the uncertainty principle there would be no consistent way to specify the correct ontology of the Universe, hence the MWI is subject to an inherent contradiction which claims that the world where we live in is unreal. Keywords: Many-Worlds Interpretation of Quantum Mechanics, (Semi-) Deterministic World, Fiducial World, Inclusive Consciousness. I. INTRODUCTION About a century after its inception, quantum mechanics is still in a perplexity to provide a precise comprehensive interpretation of its peculiar features. Even though, the orthodox interpretation of quantum theory, the so called Copenhagen interpretation, soon gained a worldwide acceptance for describing the quantum behaviors of the objective world around us, this quandary is still felt in the basics of quantum mechanics [1]. The most profound consideration to this dilemma dates back to 1930s when the Einstein-Podolsky-Rosen criticism of the Copenhagen interpretation of the theory, the EPR paradox [2], revealed an unexpected aspect of quantum physics which violates the main principle arXiv:2011.13928v1 [quant-ph] 27 Nov 2020 of special relativity allowing information to be transmitted faster than light. This phenomenon that was the most serious objection to the interpretation until then, was referred to as the entanglement effect by Schrodinger [3].

    To appear in Science and Ultimate Reality: From Quantum to Cosmos, honoring John Wheeler's 90th birthday, J.D. Barrow, P.C.W. Davies, & C.L. Harper eds., Cambridge University Press (2003) Parallel Universes Max Tegmark Dept. of Physics, Univ. of Pennsylvania, Philadelphia, PA 19104; [email protected] (January 23 2003.) Abstract: I survey physics theories involving parallel universes, which form a natural four-level hierarchy of multiverses allowing progressively greater diversity. Level I: A generic prediction of inflation is an infinite ergodic universe, which contains Hubble volumes realizing all initial conditions 29 | including an identical copy of you about 1010 m away. Level II: In chaotic inflation, other thermalized regions may have different physical constants, dimensionality and particle content. Level III: In unitary quantum mechanics, other branches of the wavefunction add nothing qualitatively new, which is ironic given that this level has historically been the most controversial. Level IV: Other mathematical structures give different fundamental equations of physics. The key question is not whether parallel universes exist (Level I is the uncontroversial cosmological concordance model), but how many levels there are. I discuss how multiverse models can be falsified and argue that there is a severe \measure problem" that must be solved to make testable predictions at levels II-IV.
