Does science deny God? Did the Universe and life appear by chance
or is there evidence of a bigger scheme of thing behind them? In
this context, I am concerned with answering these questions. This
problem is addressed using knowledge in cosmology, physics and
biology. The initial part describes the stages of the 'Genesis'
according to physical cosmology from the Big Bang to the appearance
of life on Earth. It will touch on problems of why the universe is
dominated by matter, the theory of inflation, the limits of our
knowledge on the early Universe, the lack of a theory that can
allow us to study the phases immediately after the Big Bang, the
relation between the concepts of quantum mechanics and the
existence of God. It shows how the Universe is finely regulated,
that is, the physical constants have been chosen so that life
appears in the Universe. The regulation is so strong that we are
forced to think the existence of a great designer who has created a
particular Universe like the one we are observing. This conclusion
can be avoided only if there is an infinity of universes, a
multiverse. We ask ourselves if science can create the Universe
from nothing and using the same arguments of cosmologists such as
Krauss (author of The Universe from Nothing). It is now known that
the current science does not allow the creation of a Universe from
absolutely nothing. Physics and cosmology do not deny God. Indeed,
the argument of the fine adjustment of constants is strongly
indicative of the existence of a great designer. Other evidence
confirming this comes from biology. Thousands of experiments in
recent decades highlight the impossibility of generating life in
the laboratory. There is an intrinsic order in life encoded in DNA
that is not present in experiments. Simple calculations show that
the 'blind and aimless' evolution described by neo-Darwinists such
as Dawkins does not allow the generation of life.

Roger Penrose, one of the most accomplished scientists of our time,
presents the only comprehensive and comprehensible account of the
physics of the universe. From the very first attempts by the Greeks
to grapple with the complexities of our known world to the latest
application of infinity in physics, "The Road to Reality" carefully
explores the movement of the smallest atomic particles and reaches
into the vastness of intergalactic space. Here, Penrose examines
the mathematical foundations of the physical universe, exposing the
underlying beauty of physics and giving us one the most important
works in modern science writing.
This book discusses analogies between relativistic cosmology and
various physical systems or phenomena, mostly in the earth
sciences, that are described formally by the same equations. Of the
two independent equations describing the universe as a whole, one
(the Friedmann equation) has the form of an energy conservation
equation for one-dimensional motion. The second equation is fairly
easy to satisfy (although not automatic): as a result, cosmology
lends itself to analogies with several systems. Given that a
variety of universes are mathematically possible, several analogies
exist. Analogies discussed in this book include equilibrium beach
profiles, glacial valleys, the shapes of glaciers, heating/cooling
models, freezing bodies of water, capillary fluids, Omori's law for
earthquake aftershocks, lava flows, and a few mathematical
analogies (Fibonacci's sequence, logistic equation, geodesics of
various spaces, and classic variational problems). A century of
research in cosmology can solve problems on the other side of an
analogy, which in turn can suggest ideas in gravity. Finding a
cosmic analogy solves the inverse variational problem of finding a
Lagrangian and a Hamiltonian for that system, when nobody thought
one exists. Often, the symmetries of the cosmological equations
translate in new symmetries of the analogous system. The book
surprises the reader with analogies between natural systems and
exotic systems such as possible universes.
Cosmology is the study of the origin, size, and evolution of the
entire universe. Every culture has developed a cosmology, whether
it be based on religious, philosophical, or scientific principles.
In this book, the evolution of the scientific understanding of the
Universe in Western tradition is traced from the early Greek
philosophers to the most modern 21st century view. After a brief
introduction to the concept of the scientific method, the first
part of the book describes the way in which detailed observations
of the Universe, first with the naked eye and later with
increasingly complex modern instruments, ultimately led to the
development of the "Big Bang" theory. The second part of the book
traces the evolution of the Big Bang including the very recent
observation that the expansion of the Universe is itself
accelerating with time.

This book describes some of the frontier problems of cosmology: our
almost total ignorance of what the Universe is made up of, the
mystery of its origin and its end. The book starts with a
description of the historical events that led to the construction
of the Big Bang model together with the stages that transformed the
Universe from a very hot place to a very cold one, full with the
structures that we observe today. These structures (stars,
galaxies, etc.) constitute only 5% of the contents of the Universe.
Concerning the remaining 95%, dubbed dark matter and dark energy,
we know very little, and we have only indirect evidence of their
existence. The text describes the story and the protagonists who
showed the need for the existence of this 'missing matter', the
observations, and puzzles they had to solve to understand that dark
matter was not ordinary matter. The book describes the hunt for
dark matter, carried out with instruments operating in space, on
the Earth's surface, and in laboratories built in the bowels of the
Earth. It also describes dark energy, which manifests itself in the
accelerated expansion of the Universe, and appeared only a few
billions of years ago. The book discusses why dark energy must
exist and what its existence implies, especially for the future and
the end of our Universe.
Bringing his cosmic perspective to civilization on Earth, Neil
deGrasse Tyson, bestselling author of Astrophysics for People
in a Hurry, shines new light on the crucial fault lines of
our time–war, politics, religion, truth, beauty, gender, race,
and tribalism–in a way that stimulates a deeper sense of unity
for us all. In a time when our political and cultural perspectives
feel more divisive than ever, Tyson provides a much-needed antidote
to so much of what divides us, while making a passionate case for
the twin engines of enlightenment–a cosmic perspective and the
rationality of science. After thinking deeply about how a scientist
views the world and about what Earth looks like from space, Tyson
has found that terrestrial thoughts change as our brain resets and
recalibrates life's priorities, along with the actions we might
take in response. As a result, no outlook on culture, society, or
civilisation remains untouched. In Starry Messenger, Tyson
reveals just how human the enterprise of science is. Far from a
cold, unfeeling undertaking, scientific methods, tools, and
discoveries have shaped modern civilisation and created the
landscape we've built for ourselves on which to live, work, and
play. Tyson shows how an infusion of science and rational thinking
renders worldviews deeper and more informed than ever before–and
exposes unfounded perspectives and unjustified emotions. With
crystalline prose and an abundance of evidence, Starry
Messenger walks us through the scientific palette that sees
and paints the world differently. From lessons on resolving global
conflict to reminders of how precious it is to be alive, Tyson
reveals, with warmth and eloquence, ten surprising, brilliant, and
beautiful truths of human society, informed and enlightened by
knowledge of our place in the universe.
This Model of the Universe concludes the universe to be a spherical
region within a much larger region of primordial matter. Primordial
Matter is determined to be an endless array of positroniums; matter
(+) and antimatter (-) particles, stabilized in and by an equally
spaced (.6 cm) hexahedron arrangement. When positron + and electron
- particles come in contact they annihilate into photons; when
photon concentrations become adequate, they precipitate into
corporeal matter of the universe. The initial annihilation started
a chain reaction from a single + & - pair which upset the
positronium rotation synchronization. Photons from annihilations
propagate in all directions and produce more continuing chain
reaction annihilations. Outward flowing photon concentrations
coalesce and precipitate into subatomic particles. Accretions of
particles produce the objects and matter of the universe. The
continuing process is called the deflagration wave, because a
simple understandable analogy relates to a flame propagating
through dry grass: matter is not created nor destroyed; it is only
converted from one form of matter into another. All processes in
this Model have been proven, and verified; all are consistent with
the Laws of Physics.
Our Universe is amazing. This is its story, told in simple
language. The story tells how the Universe came to be what it is
today. It starts with the Big Bang and describes how stars, black
holes, and our solar system developed. It explores the evolution of
life on Earth and investigates the possibility of extra-terrestrial
life. It peers into the future and wonders about the Universe's
likely old age and death, or whatever else may be its end. The
challenge the book takes up is to explain all of this, including
some of the astonishing concepts we have in science, such as
Einstein's theories of Relativity and Quantum Mechanics, using
virtually no mathematics and without dumbing-down. All are
described narratively and explained using examples and anecdotes.
The book is written for young people with a thirst for learning
about the science of space, as well as for 'grown-ups' who want a
better understanding of this fascinating subject.
This volumes in the Greenwood Guides to the Universe series covers
the current scientific understanding of the creation and evolution
of the universe. Cosmology and the Evolution of the Universe
provides readers with an up-to-date survey of the current
scientific understanding of how the universe has evolved in the
almost 14 billion years since the Big Bang. Scientifically sound
and written with the student in mind, it is an excellent first step
for students researching the science of cosmology and a resource
for all who wish to know more about the evolution of the universe.
Cosmology and the Evolution of the Universe discusses all areas of
what is known about the subject. Topics include: the large-scale
structure of the universe; the discovery and importance of cosmic
microwave background radiation; and the forces and particles
involved in the evolution of the universe. The book even tackles
that most provocative of questions: How will the universe end?
Thematic chapters enhance understanding of the broad concepts
presented 66 illustrations make it easier for students to grasp the
subjects discussed A glossary of scientific and astrology-related
terms facilitates reading and understanding A bibliography of
useful resources puts readers on the right track to learn more
about the subjects discussed
