Book Description
'Includes exciting recent advances in studying gravity and its cosmic manifestations.' Lord Martin Rees, Astronomer Royal, former President of the Royal Society A fascinating historical account of how we have reached our current understanding of gravity. There have been sensational developments in gravitational physics in recent years. The detection of gravitational waves - ripples in the fabric of space - has opened a new window on the universe. These waves are produced by the most cataclysmic events in the universe - the collisions and mergers of black holes and neutron stars. There have also been great strides in our understanding of supermassive black holes. We now know that a black hole with a gargantuan mass lies at the heart of every galaxy, and we even have an image of one such beast. Gravity: From Falling Apples to Supermassive Black Holes provides an engaging and accessible account of how we have reached our current understanding of gravity and places these amazing discoveries in their true context. Gravity: From Falling Apples to Supermassive Black Holes is written in a captivating historical style with stories about the researchers of the past and present that illuminate many key ideas in astronomy and physics. The historical material leads from discussions of the early cosmologies to the great breakthroughs of Tycho and Kepler. We then consider Galileo's contributions to astronomy and mechanics, and the significance of Jeremiah Horrocks's ideas to the Newtonian revolution that would follow. Newton's theories brought about a new scientific age and his description of gravity was unrivalled for over two centuries until it was superseded by Einstein's description in terms of curved spacetime. The outlandish predictions of Einstein's theory have been confirmed again and again, including black holes and gravitational waves. Finally, we move on to more speculative ideas including Hawking radiation and primordial black holes and attempts to find a quantum theory of gravity.

Book Description
Black holes, supernovas, Dark matter, and the micro gravity or macro gravity related researches and studies for analysis can be of inbound curiosity to any professional in any subject stream. These are lessons about nature that is sure to trigger the curiosity in anyone. Shedding some light on these vitalities related to black holes, formation, creation, and deterioration is the objective here. Enormous amount of gases in the black holes, in varied capacities, and the unpredictable size and nature of the black holes, with super gravity, make the studies to be too complicated to understand precisely about the physical properties of the black holes. To describe the difference between gravitational and inertial mass, brings in the need to know on when an astronaut in orbit experiences apparent weightlessness. That is the way to understand on how black holes are formed for anyone else too.

Book Description
Quasars, and the menagerie of other galaxies with "unusual nuclei", now collectively known as Active Galactic Nuclei or AGN, have, in one form or another, sparked the interest of astronomers for over 60 years. The only known mechanism that can explain the staggering amounts of energy emitted by the innermost regions of these systems is gravitational energy release by matter falling towards a supermassive black hole --- a black hole whose mass is millions to billions of times the mass of our Sun. AGN emit radiation at all wavelengths. X-rays originating at a distance of a few times the event horizon of the black hole are the emissions closest to the black hole that we can detect; thus, X-rays directly reveal the presence of active supermassive black holes. Oftentimes, however, the supermassive black holes that lie at the centers of AGN are cocooned in gas and dust that absorb the emitted low energy X-rays and the optical and ultraviolet light, hiding the black hole from view at these wavelengths. Until recently, this low-energy absorption presented a major obstacle in observational efforts to map the accretion history of the universe. In 1999 and 2000, the launches of the Chandra and XMM-Newton X-ray Observatories finally broke the impasse. The impact of these observatories on X-ray astronomy is similar to the impact that the Hubble Space Telescope had on optical astronomy. The astounding new data from these observatories have enabled astronomers to make enormous advances in their understanding of when accretion occurs.

Book Description
On December 26, 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected gravitational waves generated from merging black holes for the first time in human history. Through an engaging, easily accessible approach, the origins, dynamics, and ultimate fate of black holes are thoroughly unraveled so that students without a scientific background can grasp complex physics theories. This book supports the Next Generation Science Standards' emphasis on scientific collection and analysis of data and evidence-based theories by discussing the methods research universities and space agencies use to explore black holes.

Book Description
"This engaging book delves into the bizarre and often counter-intuitive world of gravitational physics. Join distinguished astrophysicist Professor Luciano Rezzolla on this virtual journey into Einstein's world of gravity, with each milestone presenting ever more fascinating aspects of gravitation. Through gentle exposure to concepts such as spacetime curvature and general relativity, you will discover some of the most curious consequences of gravitational physics, such as black holes, neutron stars and gravitational waves. The author presents and explains one of the most impressive scientific achievements of recent times: the first image of a supermassive black hole. Written by one of the key scientists involved in producing these results, you'll get a behind-the-scenes view of how the image was captured and discover what happens to matter and light near a black hole"--

Book Description
We all encounter gravity every day, but most people have little understanding of what gravity actually involves. We learned about Newton in high school, but that interpretation is not a complete description of gravity. However, those interested in the subject quickly learn that the math used in our modern explanation of gravity (General Relativity) is overwhelming, suggesting that gravity can only be truly understood by highly trained scientists and mathematicians. The author rejects that notion. He believes gravity can be understood by all and can be scientifically explained using words in lieu of the complicated math. Gravity is a significant force around us, therefore our understanding of it is important to make sense of the universe in which we all live. The universe is constantly changing, and those changes that are not fully understood influence what we think we see when we look far away-to the past. This book offers a unique path for exploring gravity and gravitation and introduces exceptional ways to think about the subject. Each aspect of gravity and gravitation is clearly explained, and the reader is guided through every step as ideas are developed into scientific models. These models are then used to explore how gravity and gravitation may have shaped the universe. The book has a potential audience far beyond students and academic environments. The author's goal is to provide a real science book that is of interest to the general reader but will also hold the interest of experts in the field.

Book Description
"In 1916, Einstein became the first to predict the existence of gravitational waves: sounds without a material medium generated by the unfathomably energy-producing collision of black holes. Now, Janna Levin, herself an astrophysicist, recounts the story of the search, over the last fifty years, for these elusive waves--a quest that has culminated in the creation of the most expensive project ever funded by the National Science Foundation ($1 billion-plus). She makes clear the how the waves are created in the cosmic collision of black holes, and why the waves can never be detected by telescope. And, most revealingly, she delves into the lives and fates of the four scientists currently engaged in--and obsessed with--discerning this soundtrack of the universe's history. Levin's account of the surprises, disappointments, achievements, and risks of this unfolding story provides us with a uniquely compelling and intimate portrait of the people and processes of modern science"--
