This book explores the history of the discovery of the expanding universe, one of the most exciting exploits in astronomy.
Alex Robinson returns with a ''spiritual sequel'' to his Eisner-winning debut Box Office Poison! It's been 15 years since the young cast of that beloved drama has graced the stage. Now, Our Expanding Universe introduces another Robinson ensemble to explore how time can transform a group of friends. Marriage, children, affairs, divorce… and that's just the beginning!
Cosmology - the science of the Universe at large - has experienced a renaissance in the decades bracketing the turn of the twenty-first century. Exploring our emerging understanding of cosmology, this text takes two complementary points of view: the physical principles underlying theories of cosmology, and the observable consequences of models of Universal expansion. The book develops cosmological models based on fundamental physical principles, with mathematics limited to the minimum necessary to keep the material accessible for students of physics and astronomy at the advanced undergraduate level. A substantial review of general relativity leading up to the Einstein field equations is included, with derivations of explicit formulations connecting observable features of the Universe to models of its expansion. Self-contained and up to date in respect of modern observations, the text provides a solid theoretical grounding in modern cosmology while preparing readers for the changes that will inevitably come from future observations.
Some implications and consequences of the expansion of the universe are examined. The conclusion is reached that galaxies cannot be formed as a result of the growth of perturbations that were initially small.
This is a provocative account of the astounding new answers to the most basic philosophical question: Where did the universe come from and how will it end?
Constructing the Expanding Universe provides students with a comprehensive exploration of the history of the evolving cosmos. In the text, the universe is seen as both physically and intellectually expanding as its physical characteristics evolve and our knowledge of the cosmos grows. It introduces students to fundamental scientific concepts that nurture the scientist in each and every reader. Chapter 1 helps students understand how astronomical objects are ob
A new look at the first few seconds after the Big Bang—and how research into these moments continues to revolutionize our understanding of our universe Scientists in the past few decades have made crucial discoveries about how our cosmos evolved over the past 13.8 billion years. But there remains a critical gap in our knowledge: we still know very little about what happened in the first seconds after the Big Bang. At the Edge of Time focuses on what we have recently learned and are still striving to understand about this most essential and mysterious period of time at the beginning of cosmic history. Delving into the remarkable science of cosmology, Dan Hooper describes many of the extraordinary and perplexing questions that scientists are asking about the origin and nature of our world. Hooper examines how we are using the Large Hadron Collider and other experiments to re-create the conditions of the Big Bang and test promising theories for how and why our universe came to contain so much matter and so little antimatter. We may be poised to finally discover how dark matter was formed during our universe’s first moments, and, with new telescopes, we are also lifting the veil on the era of cosmic inflation, which led to the creation of our world as we know it. Wrestling with the mysteries surrounding the initial moments that followed the Big Bang, At the Edge of Time presents an accessible investigation of our universe and its origin.
"[Mackler's] teens feel lived in to me--smart, observant, but realistic. . . Much to discuss here in the age of #MeToo." --Gabrielle Zevin, New York Times bestselling author From Carolyn Mackler, author of the Printz Honor-winning The Earth, My Butt, and Other Big Round Things, comes a story of what happens when "happily ever after" turns out to be less than perfect. It's been five months since sixteen-year-old Virginia Shreves thought her life was finally back on course: she has come to terms with who she is both inside and out, and she's even started to rebuild her relationship with her older brother Byron, whose date-rape charge completely shattered everything. But just as she's getting used to the new normal, Virginia's world turns upside down again. Sparks with boyfriend Froggy Welsh the Fourth fade, her best friend Shannon bombshells bad news, and then the police arrest Byron. As Virginia struggles to cope, she meets Sebastian, an artist with his own baggage. The pair make a pact not to share their personal dramas. But secrets have a way of coming out, and theirs have the potential to ruin everything. In this follow-up to the acclaimed The Earth, My Butt, and Other Big Round Things, Carolyn Mackler brings Virginia's story satisfyingly full circle in a hope-filled tale of forgiveness, love, friendship, and the beauty in life's imperfections.
This classic book, long out of print, investigates the experimental determination of one of the fundamental constants of astrophysics and its significance for astronomy. The equations of general relativity include a constant lambda in their solution. If lambda is non-zero and positive, this represents the existence of a phenomenon of cosmical repulsion. In this book Eddington discussed the implications of this for models of the universe. The book offers a unique sidelight upon the history of ideas and Eddington's artistry. His evident enjoyment of writing and exposition shine through, and astrophysicists and historians of science will find that this reissue throws fascinating light on one of Britain's greatest scientists.
