Download From Quarks To Black Holes - Interviewing The Universe Book in PDF, ePub and Kindle
This book presents a series of delightful interviews in which natural objects such as an electron, a black hole, a galaxy, and even the vacuum itself, reveal their innermost secrets — not only what they are but also how they feel. A hydrogen atom tells us about quantum mechanics and why we live in a non-deterministic world; a black hole explains curved space and naked singularities; and a uranium atom talks of its life on a meteor, its tremendous collision with Earth, and properties of radioactivity — all while grappling with its own mortality. A neutron star gives a personal account of its creation and goes on to discuss quasars and other extraordinary astronomical objects, while an iron atom describes its birth in a remote supernova explosion and its series of adventures on Earth, from its early use in wrought iron processes to its time in a human body, and then to its latest misadventures.The book discusses many fundamental issues in physics and, at times, examines the philosophical and moral issues of society. For example, the interview with the quark reveals the nature of color gauge symmetry, which is interwoven with a discussion on truth and beauty, and shows how these concepts play an integral part in physics and nature, while the uranium atom expresses its horror of the development and use of the atomic bomb.

Download Supermassive Black Holes in the Distant Universe Book in PDF, ePub and Kindle
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.

Download Gravity's Fatal Attraction Book in PDF, ePub and Kindle
Richly illustrated with the images from observatories on the ground and in space, and computer simulations, this book shows how black holes were discovered, and discusses our current understanding of their role in cosmic evolution. This second edition covers new discoveries made in the past decade, including definitive proof of a black hole at the center of the Milky Way, evidence that the expansion of the Universe is accelerating, and the new appreciation of the connection between black holes and galaxy formation. There are entirely new chapters on gamma-ray bursts and cosmic feedback. Begelman and Rees blend theoretical arguments with observational results to demonstrate how both approaches contributed to this subject. Clear illustrations and photographs reveal the strange and amazing workings of our universe. The engaging style makes this book suitable for introductory undergraduate courses, amateur astronomers, and all readers interested in astronomy and physics.

The whole universe is full of miracles. The Massive Black holes are massive objects collections of mass, with gravity so strong that nothing can escape, not even light. Black holes are among the strangest things in the universe. The most common types of black holes are the stellar-mass and super massive black holes. Stellar, mass black holes, are created when massive stars explode, leaving behind a black hole with the mass of just a few suns. "These are incredibly fast-moving objects that are actually gravitationally unbound to the Milky Way." Though these speed demons may be close to the black hole, they are not shrouded by dust and can be detected with telescopes. A stellar black hole can be seen when it rips a companion star to pieces. When a massive star explodes, not all the material is ejected into space. Some of it collapses into an extremely compact object known as a neutron star, inside which gravitational forces crush protons and electrons together, turning them into particles known as neutrons. A neutron star contains a few solar masses of material squeezed into a radius of only 20 km. This means the matter is so compressed that a thimble full of it would weigh millions of tonnes on Earth. Fast-spinning neutron stars, whose radio emissions seem to pulse on and off, are called pulsars. Quasars is the brightest objects in the universe, they shine anywhere from 10 to 100,000 times brighter than the Milky Way. Shining so brightly that they eclipse the ancient galaxies that contain them, quasars are distant objects powered by black holes a billion times as massive as our sun. These powerful dynamos have fascinated astronomers since their discovery half a century ago. Light-speed jets, the tiny point-like glimmers, are actually signals from galactic nuclei outshining their host galaxies. Quasars live only in galaxies with super massive black holes, black holes that contain billions of times the mass of the sun. Although light cannot escape from the black hole itself, some signals can break free around its edges. While some dust and gas fall into the black hole, other particles are accelerated away from it at near the speed of light. The particles stream away from the black hole in jets above and below it, transported by one of the most powerful partiparticle accelerators in the universe.

Download Black Holes Book in PDF, ePub and Kindle
Black holes are undoubtedly one of the most fascinating discoveries of modern astronomy, and their description one of the most daring intellectual feats of modern times. They have already become legendary, forming the basis of many myths, fantasies and science fiction movies. Are they really the monsters which devour light and stars; bottomless celestial pits into which all matter is sucked and crushed? Are they an observable reality, or are they just hypothetical objects from the theory of relativity? In answering such questions the author takes us on a fabulous journey through space and time. Dr Jean-Pierre Luminet is an astronomer at Meudon Observatory in France, a specialist on the subject of black holes, and has also acquired a reputation for being a gifted writer and communicator. In this book he makes the subject of black holes accessible to any interested reader, who will need no mathematical background.
