Modern Cosmology
Modern Cosmology, Third Edition provides a detailed introduction to the field of cosmology.Beginning with the smooth, homogeneous universe described by a Friedmann-Lemaître-Robertson-Walker metric, this trusted resource includes careful treatments of dark energy, big bang nucleosynthesis, recombination, and dark matter.The reader is then introduced to perturbations about an FLRW universe: their evolution with the Einstein-Boltzmann equations, their primordial generation by inflation, and their observational consequences: the acoustic peaks in the CMB; the E/B decomposition in polarization; gravitational lensing of the CMB and large-scale structure; and the BAO standard ruler and redshift-space distortions in galaxy clustering. This revised third edition includes updates such as new sections on gravitational waves, line intensity mapping, and emergent analysis techniques; expanded sections of CMB secondaries; and revised figures and pedagogy.These revisions serve to enhance a comprehensive foundational text, as well as provide users with improvements that are aligned with recent advances in the field, as well as modern focuses in the classroom.

A Cosmology of Monsters
"I loved it, and think you will, too."--Stephen KingStephen King's It meets Stranger Things in a tender and terrifying coming-of-age tale of haunted houses and the monster at the door. Noah Turner's family are haunted by monsters that are all too real, strange creatures that visit them all: His bookish mother Margaret; Lovecraft-obsessed father Harry; eldest sister Sydney, born for the spotlight; the brilliant but awkward Eunice, a gifted writer and storyteller - the Turners each face their demons alone. When his terminally-ill father becomes obsessed with the construction of an elaborate haunted house - the Wandering Dark - the family grant his last wish, creating themselves a legacy, and a new family business in their grief.But families don't talk about the important things, and they try to shield baby Noah from horrors, both staged and real. As the family falls apart, fighting demons of poverty, loss and sickness, the real monsters grow ever closer.Unbeknownst to them, Noah is being visited by a wolfish beast with glowing orange eyes.Noah is not the first of the Turners to meet the monster, but he is the first to let it into his room...

Why does cosmology make me cry?
Cosmology can evoke strong emotions because it confronts us with the vastness and complexity of the universe, and our small place within it. The realization of our own insignificance in the grand scheme of the cosmos can be overwhelming and humbling. Additionally, contemplating the mysteries of the universe, such as the origins of the universe or the possibility of other intelligent life forms, can stir up deep existential questions and emotions. Ultimately, the profound nature of cosmology can lead to a sense of awe, wonder, and even a feeling of being deeply connected to something much larger than ourselves, which can be deeply moving.

What is the difference between astronomy and cosmology?
Astronomy is the scientific study of celestial objects such as stars, planets, and galaxies, as well as the phenomena that occur outside the Earth's atmosphere. It focuses on observing and understanding the physical properties and behavior of these objects. On the other hand, cosmology is a branch of astronomy that specifically deals with the origin, evolution, and eventual fate of the universe as a whole. It seeks to understand the large-scale structure and dynamics of the universe, including the nature of dark matter and dark energy, the Big Bang theory, and the formation of galaxies and large-scale cosmic structures. In summary, astronomy focuses on the study of individual celestial objects, while cosmology focuses on the universe as a whole.

Cosmology for the Curious
This book is a gentle introduction for all those wishing to learn about modern views of the cosmos.Our universe originated in a great explosion – the big bang.For nearly a century cosmologists have studied the aftermath of this explosion: how the universe expanded and cooled down, and how galaxies were gradually assembled by gravity.The nature of the bang itself has come into focus only relatively recently.It is the subject of the theory of cosmic inflation, which was developed in the last few decades and has led to a radically new global view of the universe. Students and other interested readers will find here a non-technical but conceptually rigorous account of modern cosmological ideas - describing what we know, and how we know it.One of the book's central themes is the scientific quest to find answers to the ultimate cosmic questions: Is the universe finite or infinite?Has it existed forever? If not, when and how did it come into being? Will it ever end?The book is based on the undergraduate course taught by Alex Vilenkin at Tufts University.It assumes no prior knowledge of physics or mathematics beyond elementary high school math.The necessary physics background is introduced as it is required.Each chapter includes a list of questions and exercises of varying degree of difficulty.This new edition includes hints for answering the questions and exercises, as well as extensions to the discussions on dark matter, quantum cosmology.A new chapter summarizing the standard cosmological model has also been added.

Classical and Quantum Cosmology
This comprehensive textbook is devoted to classical and quantum cosmology, with particular emphasis on modern approaches to quantum gravity and string theory and on their observational imprint.It covers major challenges in theoretical physics such as the big bang and the cosmological constant problem.An extensive review of standard cosmology, the cosmic microwave background, inflation and dark energy sets the scene for the phenomenological application of all the main quantum-gravity and string-theory models of cosmology. Born of the author's teaching experience and commitment to bridging the gap between cosmologists and theoreticians working beyond the established laws of particle physics and general relativity, this is a unique text where quantum-gravity approaches and string theory are treated on an equal footing.As well as introducing cosmology to undergraduate and graduate students with its pedagogical presentation and the help of 45 solvedexercises, this book, which includes an ambitious bibliography of about 3500 items, will serve as a valuable reference for lecturers and researchers.

Cosmology and String Theory
Cosmology describes the evolution of the Universe and is based on a description of its beginning from quantum fluctuations.String theory is the only known consistent theory of quantum gravity that can deal with the highest energy scales near the Planck energy, relevant for cosmology's beginning.As a result, only string theory can give a fully consistent picture of cosmological origins.This book describes the best current avenues for obtaining cosmology from string theory.It is aimed at graduate students, and also researchers, with some familiarity with cosmology and string theory, however no detailed knowledge is required.

What are the professions in the field of astronomy/cosmology?
Professions in the field of astronomy/cosmology include astronomers, who study celestial objects and phenomena, such as stars, planets, and galaxies, using telescopes and other instruments. Astrophysicists, on the other hand, focus on the physical properties and behavior of celestial objects, often using principles of physics to understand their nature. Cosmologists study the origins and evolution of the universe as a whole, including its large-scale structure and dynamics. These professionals may work in academic research, observatories, space agencies, or in science communication and education.

What do artists do at electronic dance music concerts?
At electronic dance music concerts, artists typically perform live DJ sets or produce music using electronic equipment such as synthesizers, drum machines, and computers. They create and mix music on the spot, often incorporating elements of different genres and styles to keep the audience engaged and dancing. Artists also interact with the crowd, hyping them up and creating a high-energy atmosphere through their music and stage presence. Additionally, some artists may incorporate visual effects and lighting to enhance the overall concert experience.
