Cycles of Time
From Nobel prize-winner Roger Penrose, this groundbreaking book is for anyone "who is interested in the world, how it works, and how it got here" (New York Journal of Books). Penrose presents a new perspective on three of cosmology’s essential questions: What came before the Big Bang? What is the source of order in our universe? And what cosmic future awaits us? He shows how the expected fate of our ever-accelerating and expanding universe—heat death or ultimate entropy—can actually be reinterpreted as the conditions that will begin a new “Big Bang.” He details the basic principles beneath our universe, explaining various standard and non-standard cosmological models, the fundamental role of the cosmic microwave background, the paramount significance of black holes, and other basic building blocks of contemporary physics. Intellectually thrilling and widely accessible, Cycles of Time is a welcome new contribution to our understanding of the universe from one of our greatest mathematicians and thinkers.
The Beginning and the End
In this fascinating journey to the edge of science, Vidal takes on big philosophical questions: Does our universe have a beginning and an end or is it cyclic? Are we alone in the universe? What is the role of intelligent life, if any, in cosmic evolution? Grounded in science and committed to philosophical rigor, this book presents an evolutionary worldview where the rise of intelligent life is not an accident, but may well be the key to unlocking the universe's deepest mysteries. Vidal shows how the fine-tuning controversy can be advanced with computer simulations. He also explores whether natural or artificial selection could hold on a cosmic scale. In perhaps his boldest hypothesis, he argues that signs of advanced extraterrestrial civilizations are already present in our astrophysical data. His conclusions invite us to see the meaning of life, evolution and intelligence from a novel cosmological framework that should stir debate for years to come.
The Evolving Universe
This revolutionary book proposes that the universe did not begin with a Big Bang and that it is slowly converging to an equilibrium state. Key features of the book include: ? The modern model of the atom. ? How the Earth and Solar System formed. ? Evolution of life on Earth. ? Nucleosynthesis in stars. ? Recent changes in the Solar System. ? The various entities in the universe, including black holes, quasars and supernovas. ? The interstellar medium. ? The classical theory of relativity. ? Beunkers alternative theory of relativity. ? The Steady State Universe theory. ? The Big Bang theory of the universe is disproved. ? Redshift is caused by cosmic dust, not the Doppler Effect and an expanding universe. ? The universe is flat and infinite. ? Cosmic background radiation comes from the interstellar medium, not the Big Bang. ? Alternative scientific theories of the universe, including cyclic models. ? Religious and alien design theories of creation. ? Were bacteria from space the first life on Earth? ? The new Evolving Universe (towards equilibrium) model of the universe based on known changes in the last 10+ billion years. ? A simple proof of gravitational deflection of light. ? G.A. Mohrs large curvature correction for Finite Element Analysis. Industry and reader comment has included: Some provocative and timely issues. A huge topic. The legendary John Argyris called G. A. Mohr The greatest scientist in Australia.
