Available in PDF, EPUB and Kindle. Book excerpt: Many observations are interpreted in terms of the then-current paradigm. Here, a review of almost 1290 scientific papers shows that the significance of some key observations have not been appreciated while some key facts have been ignored. It is assumed planets formed from a distribution of planetesimals, but we do not know how dust accreted to planetesimals. Oligarchic accretion should not apply beyond 10 AU, but this would mean LkCa 15b, and TYC 8998-760-1 b and c were impossible. The atmospheres of three of our rocky planets have clearly different atmospheric compositions, but they are supposed to come from one source, which has the wrong elemental ratios for any of them. The early Earth atmosphere is believed to have been oxidized, but samples from the time show that the atmosphere contained much methane, and the oceans much ammonia. We cannot understand how Mars could have running water, yet there are river valleys. This book argues these and many other problems go away if we assume the initial accretion was caused by chemistry, including physical chemistry, and our solar system is an archetype for planetary formation. If our water was ammoniacal, why could not the Martian water have been, in which case it would flow at the obvious low temperatures. The case is made that life can only evolve from a planet with Earth’s chemistry, and it evolved around fumaroles. There are at least seven reasons why there will be no life under-ice at Europa. These conclusions mainly come from putting together information already known, together with a few original propositions. The book ends with a large number of predictions, including some from experiments that could be carried out in a lab on Earth.
Download or read book Planetary Formation written by Celestial Angell and published by Dedona Publishing. This book was released on with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planetary formation is a captivating process that unfolds over millions to billions of years, sculpting the celestial bodies that populate our cosmos. It begins within the swirling embrace of a protoplanetary disk, a vast expanse of gas and dust leftover from the birth of a new star. Within this cosmic crucible, tiny grains of dust collide and coalesce, forming larger and larger aggregates known as planetesimals. Through the relentless pull of gravity, these planetesimals grow into protoplanets, embryonic worlds with the potential to one day become full-fledged planets. As these protoplanets continue to accrete material from the surrounding disk, they undergo a dynamic interplay of gravitational interactions, collisions, and mergers. Some protoplanets may grow to become gas giants, like Jupiter and Saturn, while others may evolve into terrestrial planets, such as Earth and Mars. The process of planetary differentiation further shapes these nascent worlds, as heavier elements sink toward their cores, creating layered structures with distinct compositions and properties.

Download or read book Pierre Teilhard De Chardin on People and Planet written by Celia Deane-Drummond and published by Routledge. This book was released on 2017-07-05 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humanity's relationship to nature is central to the work of Pierre Teilhard de Chardin, an influential priest and scientist of the twentieth century. Teilhard believed that spiritual development must be viewed alongside material development and that evolutionary theory lies at the heart of humanity's understanding of its place in the world. 'Pierre Teilhard de Chardin on People and Planet' argues that Teilhard's cosmic mysticism and intense interest in both cosmological and evolutionary sciences are highly relevant to current debates about how best to construct a meaningful spirituality. The book offers a critical revision of Teilhard's thought in the light of current debates in evolutionary science, eco-theology and environmental ethics. The essays present fresh interpretations of Teilhard's work and point to the significance of his thought in the contemporary study of science and religion.
Download or read book Earths of Distant Suns written by Michael Carroll and published by Springer. This book was released on 2016-10-03 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the latest missions results and supported by commissioned artwork, this book explores the possible lessons we may learn from exoplanets. As the number of known Earth-like objects grows significantly, the author explores what is known about the growing roster of "pale blue dots" far afield. Aided by an increased sensitivity of the existing observatories, recent discoveries by Keck, the Hubble Space Telescope, and Kepler are examined. These findings, once thought to be closer to the realm of science fiction, have fired the imaginations of the general public as well as scientists. All of us are mesmerized by the possibility of other Earth-like worlds out there. Author Michael Carroll asks the tough questions of what the expected gain is from identifying these Earth analogs spread across the Universe and the reasons for studying them. Potentially, they could teach us about our own climate and Solar System. Also explored are the more remote options of communication between or even travel to these distant yet perhaps not so dissimilar worlds.
Download or read book Creation Behold it was very good written by Richard Schaefer and published by Lulu.com. This book was released on 2019-10-28 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author Richard A. Schaefer was a lifelong communicator, fascinated by stories and, like any good journalist, dug for the facts and verified sources, exploring nagging questions such as "Is creation or evolution more credible, based on science and expert opinions?" This book truly represented a personal passion of looking at all sides of the CREATION vs. EVOLUTION issue. He called on many experts and theorists-including Charles Darwin himself. Surprisingly, Darwin was far more skeptical of his own theories than are many PhDs today, and admitted to significant holes in his logic. Read for yourself, as great thinkers explore the pros and cons of both theories and their variants.

Available in PDF, EPUB and Kindle. Book excerpt: This book explores anew the theme of creation in Scripture, tradition, and contemporary theology. David Fergusson defends the classical account of creation out of nothing but gives more sustained attention than the Christian tradition typically has given to the holistic significance of the created world. Offering both doctrinal exposition and apologetic argument, Fergusson discusses creation in relation to the problem of evil and the fall, divine providence, deism, Darwinian evolution, environmental ethics, animal rights, and other matters. Unusually, the book also touches on the topic of extraterrestrial intelligence. Concise and accessible, Fergusson s Creation will be particularly useful to students and others seeking a well-informed overview of this important subject.

Available in PDF, EPUB and Kindle. Book excerpt: A book that takes a look at the theory of evolution, and a look at creation. Some of the questions that are covered in her new book are - What are the real facts behind evolution? Were we designed by Intelligence? Did dinosaurs and man really coexist? What the earth's crust tells us. How the Great Flood fits the fossil record. What were the Father of Evolution Charles Darwin's real thoughts on his own theory of evolution? What some evolutionists say on this theory. Louis Pasteur did multiple experiments on Darwin's theory. What were his findings? All evidence and proof point to ... ? The evolution/creation controversy is not just a scientific issue.In her book, she is going to show you the reasons why she thinks the evolution theory is wrong and how creation gives a better account. She believes students-and people in general-should feel free to choose for themselves among these ideas and to be able to exercise their freedoms of thought and of opinion.
