If scientists can’t touch the Sun, how do they know what it’s made of? And if we can’t see black holes, how can we be confident they exist? Gravitational physicist David Garfinkle and his brother, science fiction writer Richard Garfinkle, tackle these questions and more in Three Steps to the Universe, a tour through some of the most complex phenomena in the cosmos and an accessible exploration of how scientists acquire knowledge about the universe through observation, indirect detection, and theory. The authors begin by inviting readers to step away from the Earth and reconsider our Sun. What we can directly observe of this star is limited to its surface, but with the advent of telescopes and spectroscopy, scientists know more than ever about its physical characteristics, origins, and projected lifetime. From the Sun, the authors journey further out into space to explore black holes. The Garfinkle brothers explain that our understanding of these astronomical oddities began in theory, and growing mathematical and physical evidence has unexpectedly supported it. From black holes, the authors lead us further into the unknown, to the dark matter and energy that pervade our universe, where science teeters on the edge of theory and discovery. Returning from the depths of space, the final section of the book brings the reader back down to Earth for a final look at the practice of science, ending with a practical guide to discerning real science from pseudoscience among the cacophony of print and online scientific sources. Three Steps to the Universe will reward anyone interested in learning more about the universe around us and shows how scientists uncover its mysteries.

The discoveries in physics that inform current dark matter theory, everything from Newtonian gravity to Einstein's relativity to the Higgs boson, are examined in this authoritative guide. It examines the biggest question facing physicists today: if we are only seeing about four percent of matter in the universe, what is the rest of it made of? The lengths that scientists are going to find what they call dark matter are revealed. Alternative theories to dark matter are also discussed, as are the scientists who don't believe that dark matter exists and are conducting their own experiments to disprove its existence.

The ordinary atoms that make up the known universe—from our bodies and the air we breathe to the planets and stars—constitute only 5 percent of all matter and energy in the cosmos. The rest is known as dark matter and dark energy, because their precise identities are unknown. The Cosmic Cocktail is the inside story of the epic quest to solve one of the most compelling enigmas of modern science—what is the universe made of?—told by one of today's foremost pioneers in the study of dark matter. Blending cutting-edge science with her own behind-the-scenes insights as a leading researcher in the field, acclaimed theoretical physicist Katherine Freese recounts the hunt for dark matter, from the discoveries of visionary scientists like Fritz Zwicky—the Swiss astronomer who coined the term "dark matter" in 1933—to the deluge of data today from underground laboratories, satellites in space, and the Large Hadron Collider. Theorists contend that dark matter consists of fundamental particles known as WIMPs, or weakly interacting massive particles. Billions of them pass through our bodies every second without us even realizing it, yet their gravitational pull is capable of whirling stars and gas at breakneck speeds around the centers of galaxies, and bending light from distant bright objects. Freese describes the larger-than-life characters and clashing personalities behind the race to identify these elusive particles. Many cosmologists believe we are on the verge of solving the mystery. The Cosmic Cocktail provides the foundation needed to fully fathom this epochal moment in humankind’s quest to understand the universe.

The fi eld of cosmology may be on the verge of a signifi cant paradigm shift, as there is an increasing awareness that scientists have missed something fundamental as they carry on in their quest for a theory of everything and a theory that unites general relativity with quantum mechanics. Knight proposes a new theory suggesting that the space-time geometry possesses a complex hierarchical structure that comprises twelve dimensionsnine space dimensions and three time. Furthermore, this structure is divided into three strata, each of which has its own four-dimensional structure and stratum-specifi c fundamental forces and parameterswith variations in the gravitational constant G, the speed of light c, and the Planck constant. Through the pages of this work, this theory is further explained.

Cooking Cosmos is an exciting book that traces the history of men's endeavor to understand the Universe, and answers the eternal questions: "Who made this World?" "Where did it come from?" "How and why did it begin?" Thousands of years of continual interaction with nature has brought mankind to the present stage when we have some inkling about the working of nature. We now know that the Earth, our habitat, is only one of the planets orbiting the Sun. The Sun itself is a star among billions of stars in the Universe. We know that our solar system came into existence some 4.5 billion years ago and it is but only a tiny component of our galaxy, the Milky Way. Our Universe contains some 100 billion of galaxies. We know that the Universe itself came into existence with the Big Bang some 13.7 billion years ago and even now galaxies are receding from each other with ever increasing speed. This book takes you through the intellectual journey of mankind, unraveling the mysteries of the Cosmos. Starting from Aristotle's Earth-centered Universe, it will take you step by step to the Copernican Sun-centered Universe, to Hubble's expanding Universe, to the Big Bang, to the currently accepted accelerating Universe. In the process, the book explores the origin of space-time, black hole, black hole radiation, dark matter, dark energy, quantum gravity, string theory, all in terms comprehensible to general audiences.

A half century ago, a shocking Washington Post headline claimed that the world began in five cataclysmic minutes rather than having existed for all time; a skeptical scientist dubbed the maverick theory the Big Bang. In this amazingly comprehensible history of the universe, Simon Singh decodes the mystery behind the Big Bang theory, lading us through the development of one of the most extraordinary, important, and awe-inspiring theories in science.

In January 2004, President Bush announced a new space policy directed at human and robotic exploration of space. The National Academies released a report at the same time that independently addressed many of the issues contained in the new policy. In June, the President’s Commission on Implementation of United States Space Exploration Policy issued a report recommending that NASA ask the National Research Council (NRC) to reevaluate space science priorities to take advantage of the exploration vision. Congress also directed the NRC to conduct a thorough review of the science NASA is proposing to undertake within the initiative. This report provides an initial response to those requests. It presents guiding principles for selecting science missions that enhance and support the exploration program. The report also presents findings and recommendations to help guide NASA’s space exploration strategic planning activity. Separate NRC reviews will be carried out of strategic roadmaps that NASA is developing to implement the policy.
