Book Description
ARE WE SURROUNDED BY SOME KIND OF SPACETIME HORIZON? We are unable to witness a part of the universe. The boundary that separates us from this part of the universe is the 'Cosmological Horizon'. Anything that lies beyond our Cosmological horizon, cannot influence us in any way, not even by gravity. The world outside that just seems unreal. DO YOU KNOW THAT WE CREATE A HORIZON AROUND OURSELVES WHENEVER WE ACCELERATE? Yes! That's true, when we move or accelerate in flat spacetime (away from any gravitational influence) we actually create a horizon called 'The Rindler horizon' around ourselves. Outside this Rindler horizon like the event horizon, the part of the universe just seems unreal or non-existent. DO YOU KNOW, OUR PLANET HEATS THE MOON? Yes, our planet increases the temperature of the moon.... Further continued in this book......

Book Description
Are you one of those who are a newbie to cosmology or a student who wants to learn more astrophysics stuff? Then this book best fits you! Are we surrounded by some kind of spacetime horizon? We are unable to witness a part of the universe. This is due to the gravity of our planet and any other thing that makes us accelerate. The boundary that separates us from this part of the universe is the ‘Rindler Horizon’. Anything that lies far beyond our Rindler horizon, cannot influence us in any way, not even by gravity. If total energy in this universe is constant, then where do tides get their energy from? Moon brings tides on earth, we convert this tidal energy to light our bulbs. The tides are due to the tidal gravity of the moon. The spacetime curvature of the moon is thus responsible for this tidal force. So where is the energy that makes the tide rise coming from? From nowhere, but from the mass of the moon itself! Do you know, our planet heats the moon? Yes, our planet increases the temperature of the moon….. Buy this book to know more...

Book Description
Hey are you interested in knowing the answers to the questions like why our universe is expanding, how a photon sees our universe, Is everything predestined in photon’s perspective. and can gravity of black hole can be lensed by gravitational wavs to create a virtual black hole with no mass ? And many more. Then you should not hesitate to grab this book. Hey Hi, I am Hiten Shelar, an Astrophysicist and Philosopher. When I was a newbie to Cosmology and Astrophysics and well before that I had a bunch of Astrophysics and cosmology unanswered questions like how large our universe is, what is time and again who are we to ask these questions, etc . And as I am now an astrophysicist and a cosmologist my curiosity is fulfilled. And the fact that human is a social animal made it my mission to write a book and fulfil the unfulfilled curiosity of other people about knowing our Universe. The book is best fit for newbies as well as to people who have quite enough knowledge of our Universe. So do not forget to check out this unique product.

Book Description
The Fourth Edition of Introduction to Cosmology provides a concise, authoritative study of cosmology at an introductory level. Starting from elementary principles and the early history of cosmology, the text carefully guides the student on to curved spacetimes, special and general relativity, gravitational lensing, the thermal history of the Universe, and cosmological models, including extended gravity models, black holes and Hawking's recent conjectures on the not-so-black holes. Introduction to Cosmology, Fourth Edition includes: New theoretical approaches and in-depth material on observational astrophysics and expanded sections on astrophysical phenomena Illustrations throughout and comprehensive references with problems at the end of each chapter and a rich index at the end of the book Latest observational results from WMAP9, ACT, and Planck, and all cosmological parameters have been brought up to date. This text is invaluable for undergraduate students in physics and astrophysics taking a first course in cosmology. Extensively revised, this latest edition extends the chapter on cosmic inflation to the recent schism on eternal inflation and multiverses. Dark matter is discussed on galaxy and cluster scales, and dark matter candidates are presented, some requiring a five-dimensional universe and several representing various types of exotica. In the context of cosmic structures the cold dark matter paradigm is described. Dark energy models include the cosmological constant, quintessence and other single field models, f(R) models and models requiring extra dimensions.

Book Description
Inflationary cosmology has been developed over the last twenty years to remedy serious shortcomings in the standard hot big bang model of the universe. This textbook, first published in 2005, explains the basis of modern cosmology and shows where the theoretical results come from. The book is divided into two parts; the first deals with the homogeneous and isotropic model of the Universe, the second part discusses how inhomogeneities can explain its structure. Established material such as the inflation and quantum cosmological perturbation are presented in great detail, however the reader is brought to the frontiers of current cosmological research by the discussion of more speculative ideas. An ideal textbook for both advanced students of physics and astrophysics, all of the necessary background material is included in every chapter and no prior knowledge of general relativity and quantum field theory is assumed.

Book Description
Listing more than 500 sky targets, both near and far, in 187 challenges, this observing guide will test novice astronomers and advanced veterans alike. Its unique mix of Solar System and deep-sky targets will have observers hunting for the Apollo lunar landing sites, searching for satellites orbiting the outermost planets, and exploring hundreds of star clusters, nebulae, distant galaxies, and quasars. Each target object is accompanied by a rating indicating how difficult the object is to find, an in-depth visual description, an illustration showing how the object realistically looks, and a detailed finder chart to help you find each challenge quickly and effectively. The guide introduces objects often overlooked in other observing guides and features targets visible in a variety of conditions, from the inner city to the dark countryside. Challenges are provided for the naked eye, through binoculars and the largest backyard telescopes.
