And Abiogenesis
Historical Development of the Distinction between Bio- and Abiogenesis. Robert B. Sheldon NASA/MSFC/NSSTC, 320 Sparkman Dr, Huntsville, AL, USA ABSTRACT Early greek philosophers laid the philosophical foundations of the distinction between bio and abiogenesis, when they debated organic and non-organic explanations for natural phenomena. Plato and Aristotle gave organic, or purpose-driven explanations for physical phenomena, whereas the materialist school of Democritus and Epicurus gave non-organic, or materialist explanations. These competing schools have alternated in popularity through history, with the present era dominated by epicurean schools of thought. Present controversies concerning evidence for exobiology and biogenesis have many aspects which reflect this millennial debate. Therefore this paper traces a selected history of this debate with some modern, 20th century developments due to quantum mechanics. It ¯nishes with an application of quantum information theory to several exobiology debates. Keywords: Biogenesis, Abiogenesis, Aristotle, Epicurus, Materialism, Information Theory 1. INTRODUCTION & ANCIENT HISTORY 1.1. Plato and Aristotle Both Plato and Aristotle believed that purpose was an essential ingredient in any scienti¯c explanation, or teleology in philosophical nomenclature. Therefore all explanations, said Aristotle, answer four basic questions: what is it made of, what does it represent, who made it, and why was it made, which have the nomenclature material, formal, e±cient and ¯nal causes.1 This aristotelean framework shaped the terms of the scienti¯c enquiry, invisibly directing greek science for over 500 years. For example, \organic" or \¯nal" causes were often deemed su±cient to explain natural phenomena, so that a rock fell when released from rest because it \desired" its own kind, the earth, over unlike elements such as air, water or ¯re. -
Fine-Tuning, Complexity, and Life in the Multiverse*
Fine-Tuning, Complexity, and Life in the Multiverse* Mario Livio Dept. of Physics and Astronomy, University of Nevada, Las Vegas, NV 89154, USA E-mail: [email protected] and Martin J. Rees Institute of Astronomy, University of Cambridge, Cambridge CB3 0HA, UK E-mail: [email protected] Abstract The physical processes that determine the properties of our everyday world, and of the wider cosmos, are determined by some key numbers: the ‘constants’ of micro-physics and the parameters that describe the expanding universe in which we have emerged. We identify various steps in the emergence of stars, planets and life that are dependent on these fundamental numbers, and explore how these steps might have been changed — or completely prevented — if the numbers were different. We then outline some cosmological models where physical reality is vastly more extensive than the ‘universe’ that astronomers observe (perhaps even involving many ‘big bangs’) — which could perhaps encompass domains governed by different physics. Although the concept of a multiverse is still speculative, we argue that attempts to determine whether it exists constitute a genuinely scientific endeavor. If we indeed inhabit a multiverse, then we may have to accept that there can be no explanation other than anthropic reasoning for some features our world. _______________________ *Chapter for the book Consolidation of Fine Tuning 1 Introduction At their fundamental level, phenomena in our universe can be described by certain laws—the so-called “laws of nature” — and by the values of some three dozen parameters (e.g., [1]). Those parameters specify such physical quantities as the coupling constants of the weak and strong interactions in the Standard Model of particle physics, and the dark energy density, the baryon mass per photon, and the spatial curvature in cosmology. -
The Arrow of Time Volume 7 Paul Davies Summer 2014 Beyond Center for Fundamental Concepts in Science, Arizona State University, Journal Homepage P.O
The arrow of time Volume 7 Paul Davies Summer 2014 Beyond Center for Fundamental Concepts in Science, Arizona State University, journal homepage P.O. Box 871504, Tempe, AZ 852871504, USA. www.euresisjournal.org [email protected] Abstract The arrow of time is often conflated with the popular but hopelessly muddled concept of the “flow” or \passage" of time. I argue that the latter is at best an illusion with its roots in neuroscience, at worst a meaningless concept. However, what is beyond dispute is that physical states of the universe evolve in time with an objective and readily-observable directionality. The ultimate origin of this asymmetry in time, which is most famously captured by the second law of thermodynamics and the irreversible rise of entropy, rests with cosmology and the state of the universe at its origin. I trace the various physical processes that contribute to the growth of entropy, and conclude that gravitation holds the key to providing a comprehensive explanation of the elusive arrow. 1. Time's arrow versus the flow of time The subject of time's arrow is bedeviled by ambiguous or poor terminology and the con- flation of concepts. Therefore I shall begin my essay by carefully defining terms. First an uncontentious statement: the states of the physical universe are observed to be distributed asymmetrically with respect to the time dimension (see, for example, Refs. [1, 2, 3, 4]). A simple example is provided by an earthquake: the ground shakes and buildings fall down. We would not expect to see the reverse sequence, in which shaking ground results in the assembly of a building from a heap of rubble. -

Evidence for God
Evidence for God (part 1 of 8): Fine Tuning of Physical Laws of Universe What is Fine Tuning? Over the past century, scientists have discovered that if certain properties of the universe were changed very slightly from what they are, we would not be here. They have to be within a very narrow range for our universe to make life possible and be habitable. The universe is fine-tuned for the existence of intelligent life with a complexity and delicacy that literally defy human comprehension. The sensitivity of the „habitability‟ of the universe to small changes is called „fine-tuning.‟ This was recognized about 60 years ago by Fred Hoyle who was not a religious person at the time he made the discovery. Scientists like Paul Davies, Martin Rees, Max Tegmark, Bernard Carr, Frank Tipler, John Barrow, and Stephen Hawking, to name a few, believe in fine-tuning. These are prominent names in cosmology as they are heard in the media whenever a news headline is made. Types of Fine-Tuning 1. Fine tuning of the laws of nature. 2. Fine-tuning of the constants of physics. 3. Fine tuning of the initial conditions of the universe. We will explore each category below: 1. Fine tuning of the laws of nature There are two ways to look at this aspect of fine-tuning: 1. Precisely the right laws are needed for highly complex life to exist. If one of these were missing, such life would not be possible. To say that the laws are fine-tuned means that the universe must have precisely the right set of laws in order for highly complex life to exist. -

The Emergent, Self-Explaining Universe of Paul Davies – a Summary and Christian Response
S & CB (2012), 24, 33–53 0954–4194 PAUL HIMES The Emergent, Self-explaining Universe of Paul Davies – a Summary and christian Response Physicist Paul Davies has emerged as one of the most popular scientists of the twenty-first century, despite his critique of the scientific establishment and its perceived failure to account for the origins and rational nature of the universe. Davies argues that the scientific consensus on cosmology rests on faith, both in its failure to provide an ultimate explanation for the origin of the universe and in its blind acceptance of its rational laws. As an alternative, Davies postulates an ‘emergent’ universe which contains the cause of its own existence and which renders unnecessary any sort of a personal deity. Yet Davies’s alternative falls short of providing a satisfactory cosmic explanation. Davies himself cannot adequately account for the principle of backward causation which creates his universe, and thus his paradigm still relies on a transcendent principle that remains unexplained. Furthermore, Davies’s objections against a personal god can be answered on philosophical grounds. Thus Davies’s hypothesis does not provide a superior alternative to the Christian view of God. key words: Paul Davies, physics, universe, emergent, self-causation, quantum mechanics, cosmology, time, teleology, cosmological argument, fine-tuning introduction Douglas Adams’ classic Hitchhiker’s Guide to the Galaxy tells the story of an advanced civilisation that builds a magnificent supercomputer for the sole purpose of providing the ultimate answer to the meaning of ‘life, the universe, and everything’.

Evidence for Design in Physics and Biology: from the Origin of the Universe to the Origin of Life
52 stephen c. meyer Pages 53–111 of Science and Evidence for Design in the Universe. The Proceedings of the Wethersfield Institute. Michael Behe, STEPHEN C. MEYER William A. Dembski, and Stephen C. Meyer (San Francisco: Ignatius Press, 2001. 2000 Homeland Foundation.) EVIDENCE FOR DESIGN IN PHYSICS AND BIOLOGY: FROM THE ORIGIN OF THE UNIVERSE TO THE ORIGIN OF LIFE 1. Introduction In the preceding essay, mathematician and probability theo- rist William Dembski notes that human beings often detect the prior activity of rational agents in the effects they leave behind.¹ Archaeologists assume, for example, that rational agents pro- duced the inscriptions on the Rosetta Stone; insurance fraud investigators detect certain ‘‘cheating patterns’’ that suggest intentional manipulation of circumstances rather than ‘‘natu- ral’’ disasters; and cryptographers distinguish between random signals and those that carry encoded messages. More importantly, Dembski’s work establishes the criteria by which we can recognize the effects of rational agents and distinguish them from the effects of natural causes. In brief, he shows that systems or sequences that are both ‘‘highly com- plex’’ (or very improbable) and ‘‘specified’’ are always produced by intelligent agents rather than by chance and/or physical- chemical laws. Complex sequences exhibit an irregular and improbable arrangement that defies expression by a simple formula or algorithm. A specification, on the other hand, is a match or correspondence between an event or object and an independently given pattern or set of functional requirements. As an illustration of the concepts of complexity and speci- fication, consider the following three sets of symbols: 53 54 stephen c. -

Illuminating the Threefold Faith: An Invocation of the Seventeen Great Scholar-Adepts of Glorious Nalanda 1. Lord of Lords, arisen from the compassionate wish to benefit wandering beings, You have attained sublime protection, abandonment and realization, And liberates sentient beings through teaching dependent arising. I bow to you, Conqueror, Sun among Teachers. 2. I call to mind esteemed Nagarjuna, who, as the Conqueror prophesied, Introduced the Middle Way of the Supreme Vehicle, and was skilled in clarifying The meaning of suchness, free of extremes, as intended in the Mother of the Conquerors, Through the profound, logical presentation of dependent arising. 3. I call to mind the Bodhisattva Aryadeva, His principal spiritual son, the most learned and accomplished, Who traversed the ocean of Buddhist and other philosophies, Who is the glorious crowning jewel among all holders of Nagarjuna's treatises. 4. I call to mind esteemed Buddhapalita, Who clarified the ultimate meaning of dependent arising—thought of the Superior [Nagarjuna], Essential point of the profound, existence as mere designation and name— And has ascended to the utmost state of accomplishment. 5. I call to mind Acharya Bhavaviveka, erudite master Who introduced a philosophical view That refuted such extremes as truly existent production, While accepting commonly verified knowledge and external objects. 6. I call to mind Chandrakirti, who promulgated the complete path of Sutra and Tantra, Who was skilled in expounding the profound and vast Middle Way, In which appearance and emptiness eliminate the two extremes Through dependent arising and the merely conditional (nature of things). 7. I call to mind the Bodhisattva Shantideva, Skilled in teaching a host of fortunate disciples The truly marvellous path of great compassion Through versatile means of reasoning, profound and vast. -

After centuries of history, studded with wars and the Tibetan people. [In recent history] it wasn't when the reforms, the multitude of voices claiming opposing views Chinese took away the land from the Tibetan rich, but precisely reached cacophony in 1949, when Communist China when the monasteries were being reduced to rubble, and when invaded Tibet, forcing the young Dalai Lama, Tibet's polit- learned scholars and venerated religious leaders were being ical and spiritual leader, to flee to India in 1959. The imprisoned, and in many cases executed, that the Tibetans Tibetan Government-in-Exile is based in Dharamsala. throughout the plateau rose up and resisted. Most Tibetans do not believe, as the Chinese maintain, Most important for us Tibetans is that we are able to lead that the invasion has "liberated" them from feudal serfdom. our lives according to our beliefs. I certainly don't see a Tibet Rather, the "liberation" has resulted in the death of over 1.2 where every Tibetan is in some cave meditating or reciting million Tibetans and the destruction of over 6,000 Tibetan mantras — in fact I would like Tibet to become a modernized monasteries and cultural centers.
