Providing an introduction to the fascinating subject of black holes, this book is suitable for advanced undergraduates and first year postgraduates. It offers an introduction to the exact solutions of Einstein's vacuum field equations, describing spherical and axisymmetric (rotating) black holes.

Offers an accessible introduction to black holes requiring no mathematical background.

This book addresses graduate students in the first place and is meant as a modern compendium to the existing texts on black hole astrophysics. The authors present in pedagogically written articles our present knowledge on black holes covering mathematical models including numerical aspects and physics and astronomical observations as well. In addition, in their write-up of a panel discussion the participants of the school address the existence of black holes consenting that it has by now been verified with certainty.

Did you know that black holes are places in space that work like vacuums? They pull objects such as stars inside themselves. Find out more about these areas in space in Black Holes, part of the Deep in Space series.

One of the most exciting predictions of Einstein's theory of gravitationisthat there may exist 'black holes': putative objects whose gravitational fields are so strong that no physical bodies and signals can break free of their pull and escape. Even though a completely reliable discovery of a black hole has not yet been made, several objects among those scrutinized by astrophysicists will very likely be conformed as black holes. The proof that they do exist, and an analysis of their properties, would have a significance going far beyond astrophysics. Indeed, what is involved is not just the discovery of yet another, even if extremely remarkable, astrophysical object, but a test of the correctness of our understanding the properties of space and time in extremely strong gravitational fields. Theoretical research into the properties of black holes and into the possible corollaries of the hypothesis that they exist, has been carried out with special vigor since the beginning of the 1970s. In addition to those specific features of black holes that are important for the interpretation of their possible astrophysical manifestations, the theory has revealed a nurober of unexpected characteristics of physical interactions involving black holes. By now, a fairly detailed understanding has been achieved of the properties of the black holes, their possible astrophysical manifestations, and the specifics of the various physical processes involved. Furthermore, profound links were found between black-hole theory and such seemingly very distant fields as thermodynamics, information theory, and quantum theory.

This eBook explores current (and past) theories pertaining to the existence of black holes in our universe. It aims to provide its readers with a fundamental understanding of what black holes are, what they are composed of, and where they developed.

This book is a tribute to the beauty of New Jersey Golf Courses, New Jersey’s contribution to the legacy of golf in America and the outstanding golf course architects who designed these courses. The book demonstrate that the game of golf is much more than playing a round of golf and recording a score on the score card, but one that allows golfers of all levels to enjoy the beauty of the golf course being played. It is my hope that this book will broaden the perspective of experienced golfers about the beauty of the game of golf, the extraordinary role New Jersey played in its American beginnings, and to provide golfers and non-golfers alike with an introduction to the beauty of New Jersey golf courses.

Introduction Space, the final frontier… to explore strange new worlds, to seek out new life,and new civilizations, to boldly go where no man has gone before. ~ Gene Roddenberry *** The universe is full of surprises! We can find amazing things like galaxies, planets, comets, asteroids, moons, meteorites, and more! One of the strangest objects we can find in space is called a… black hole. Have you ever heard of black holes? What do you know about them? Let’s learn more! Black holes are dark areas in space with strong gravity. Not all black holes are black and we cannot see them, but we know they are there. How do we know they exist even though we can’t see them? Scientists study the things that happen around a black hole, and that tells them a black hole is there. The force of a black hole is so strong light cannot escape. Do you know what happens to light when it gets near a black hole? Strong gravity pulls light and everything else into the center. It is so strong that nothing escapes the powerful force, and everything falls in! Black holes come in lots of different sizes. Some are big, and some are small. Some black holes are so big; they are called supermassive black holes. That’s a big, big hole! Black holes affect not only space but time too. How so? Did you know time changes when you get near a black hole? Yes, it does! This is because of Einstein’s theory of relativity. Let’s find out how black holes work and what else we can learn about this mysterious force in the universe!
