hole s event horizonSometimes when we look at the evening sky, observe a shooting star far away or admire the beauty of moon, we are overpowered by this idea of our seemingly insignificant existence in the Universe For if we compare our very own presence, that of our world or our country, even of our planet or our galaxy with the Universe, it is bewildering that we seem to occupy not even a speck of dust as compared to the vastness of the Universe Many of us are then tempted to delve into the mysteries of this existence to make out some meaning, some significance Whereas philosophy seems to correspond to our inner being in relation to world around, we need to turn to science in order to understand our relation with the Universe The attempt thus taken, even though neither Science nor Philosophy seems to offer an absolute explanation, may bring about amodest outlook towards our existence and empathy towards fellow beings But since most of the scientific theories and their explanation are available theoretically in a technical manner, not many of us make an attempt to understand them In this work, Hawking not only suggests making scientific knowledge simpler enough for everyone so thatpeople can understand and benefit from it but also presents to us scientific theories in very simple way The work is a compilation of seven lectures delivered by Hawking in which he discusses various theories like Theory of relativity, Big Bang, Black Hole, Quantum theory, Quantum Gravity and String theory to finally propose a unified theory which might one day be able to take every known theory into account and give us an explanation of the existence of Universe Hawking is so lucid at explaining these theories and then presenting reasons as to why certain theories may not hold that even a na ve science reader like me can understand them Moreover he is also quite witty at certain places, which makes the work an enjoyable read e.gIn other words, the singularities produced by gravitational collapse occur only in places like black holes, where they are decently hidden from outside view by an event horizon Strictly, this is what is known as the weak cosmic censorship hypothesis protect observers who remain outside the black hole from the consequences of the breakdown of predictability that occurs at the singularity But it does nothing at all for the poor unfortunate astronaut who falls into the hole Shouldn t God protect his modesty as well However, in the end most people, including John Taylor, have come to the conclusion that black holes must radiate like hot bodies if our other ideas about general relativity and quantum mechanics are correct Thus even though we have not yet managed to find a primordial black hole, there is fairly general agreement that if we did, it would have to be emitting a lot of gamma and X rays If we do find one, I will get the Nobel Prize Some concepts like Black hole radiation, arrows of time and quantum theory of gravity are very interesting The idea of reverse arrow of time made my head spin in a good way Towards the end, when Hawking discusses the need of a unified theory and the question why such a theory may not be possible, he ends his lecture in the following manner However, if we do discover a complete theory, it should in time be understandable in broad principle by everyone, not just a few scientists Then we shall all be able to take part in the discussion of why the universe exists If we find the answer to that, it would be the ultimate triumph of human reason For then we would know the mind of God.I will recommend this book to all those who want a have an idea about the Universe in terms of theories developed so far I wasn t sure what to expect when I approached this book Being such a huge Einstein fan and knowing how he struggled in his own, final quest for the Theory of Everything just before he died, well, I didn t know what to think Had Hawking finally cracked that elusive nut I was originally homeless when I first discovered this book, and living in my car with my 2 cats I would head to the library on special days to kill time, and immediately go to this book and throw myself into its pages I d alw I wasn t sure what to expect when I approached this book Being such a huge Einstein fan and knowing how he struggled in his own, final quest for the Theory of

really got into the details of the theories seriously when I decided to return to college to study math and theoretical physics.I was pleasantly surprised at the amount of levity and wit Hawking used to approach his topical essays And he made a successful, conscious choice to remove most of the superfluous professor speak and attempt to keep it on a level that most non scientists could understand I commend him for that This book was a bit of an eye opener for me My favourite essays were of those on black holes The interesting thing, is that since reading this book, we have discovered the existence of hyper giants, which weren t around when Chandresekhar devised his now famous, Chandresekhar limit when calculating at what conditions an imploding star would finally fold under the mass of itself and become a black hole It makes me wonder what this now does to his limit calculations.All in all, a superb book for the scientist and non scientist alike Highly recommend This book is a boon for physics lover The author didn t include complicated mathematical equations He kept language simple and easily understandable The author mixes science with philosophy It exhibits a subtle sense of humor in the book It s a short read Stephen Hawking poses interesting questions about God All in all, a recommended reading.Read full review Books Charming This book is a boon for physics

Stephen Hawking s other books immediately.The Theory of Everything consists of lectures and notes by Prof Hawking His writing still amazes me whenever I get to have a look at his books. Not a novel per se but a collection of lectures by Mr Hawking, which explores the origins of the universe and tries to find the answer to Why does the Universe exist, anyway Stephen Hawking tries to explain the origin of the Universe or The Big Bang without going into the technicalities and also gives a brief overview of various theories present that try to explain the state of the Universe even the String theory The writing is simple but still multiple readings will be required to comple Not a novel per se but a collection of lectures by Mr Hawking, which explores the origins of the universe and tries to find the answer to Why does the Universe exist, anyway Stephen Hawking tries to explain the origin of the Universe or The Big Bang without going into the technicalities and also gives a brief overview of various theories present that try to explain the state of the Universe even the String theory The writing is simple but still multiple readings will be required to completely understand the full book for me atleast Hawking s witty propositions and his subtle doubts at the existence of THE CREATOR makes it a very enjoyable experience.A must read for anyone interested in cosmology5 5 Language is lucid However, at times theories are quite complex and simple pictorial illustrations if incorporated might have had been useful The book starts off with the ancient theories on universe evolution and gradually explains reasons for non feasibility of the same in a structured manner It is followed by explaining that why universe is non static, future of stars, different evolutionary models, flaws in them, the paradox which is created if we assume singularity to be existent at the t Language is lucid However, at times theories are quite complex and simple pictorial illustrations if incorporated might have had been useful The book starts off with the ancient theories on universe evolution and gradually explains reasons for non feasibility of the same in a structured manner It is followed by explaining that why universe is non static, future of stars, different evolutionary models, flaws in them, the paradox which is created if we assume singularity to be existent at the time of bing bang, concepts of quantum gravity and imaginary time to find solutions for fundamental limitations arising because of singularity assumption, possible histories of universe and ultimately capability of string theory to resolve unsolved mysteries At the end author has explained that why unified theory is not possible presently but might be possible in future.Author does tried to add light humour in some parts Fascinating read Audiobook was not the smart choice for this for me I m not an auditory learner and didn t take this into account So I don t think I retained any of this information However, while I listened I was completely enthralled He really does a great job of simplifying deluxe principles Thermodynamics seem to be the focus here.

supernova and the universe Take these together and mix them with a scientist Boom An explosion A Big Bang The theory of almost everything we are eager to understand about the beginning of the times This review will include a brief history of this book PUN Not only did Stephen Hawking describe those concepts easily in this book, but he also made us have free access to his deep studies He was born exactly 300 years after Galileo s death and became one of the most influential people in the area of Cosmology Don t you feel a little bit scary to get his work to read Don t you have the idea that it ll be tough and appalling I m here to demystify your wrong judgements towards this book First, is it paid off to read the analysis of a scientist who is not always right Sure it is For someone who admits having made a mistake in his first theory of black holes, Hawking deservesthan the knighthood offered by the Queen Elizabeth, which he declined by the way The term black hole was coined in 1969 by the American scientist John Wheeler I would rather grant you an excerpt from the book than trying to explain it to you a star that was sufficiently massive and compact would have such a strong gravitational field that light could not escape Any light emitted from the surface of the star would be dragged back by the star s gravitational attraction before it could get very far Although we would not be able to see them because the light from them would not reach us, we would still feel their gravitational attraction Such objects are what we now call black holes, because that is what they are black voids in space Page 37 To understand how a black hole might be formed, we first need an understanding of the life cycle of a star A star is formed when a large amount of gas, mostly hydrogen, starts to collapse in on itself due to its gravitational attraction As it contracts, the atoms of the gas collide with each otherandfrequently and at greater and greater speeds the gas heats up Eventually the gas will be so hot that when the hydrogen atoms collide they no longer bounce off each other but instead merge with each other to form helium atoms The heat released in this reaction, which is like a controlled hydrogen bomb, is what makes the stars shine This additional heat also increases the pressure of the gas until it is sufficient to balance the gravitational attraction, and the gas stops contracting It is a bit like a balloon where there is a balance between the pressure of the air inside, which is trying to make the balloon expand, and the tension in the rubber, which is trying to make the balloon smaller Pages 38 39 According to the theory of relativity, nothing can travel faster than light Thus, if light cannot escape, neither can anything else Everything is dragged back by the gravitational field So one has a set of events, a region of space time, from which it is not possible to escape to reach a distant observer This region is what we now call a black hole Page 44 Yes, black holes are not black and Stephen was humble enough to carry on studies to correct his thoughts and publicly announce his misunderstanding regarding his set of principles in print Einstein had the guts to confirm that his cosmological constant was an incorrect belief, Stephen followed his steps and it may be one of the reasons we look up to them both I do, wouldn t you Having said that, many may think that Hawking does not believe in God, yet what we see here is that he discourses about the Big Bang Theory and gives God the credit for this event Along the pages you also read how the Catholic Church admits in 1951 that the Big Bang is in accordance with the Bible The Catholic Church misperceived Copernicus and Galileo regarding their theory of the Earth being the centre of the universe and it invited some experts to advise it on cosmology in the Vatican in 1981 It was when Hawking attended this conference that his interest in the origin of the universe was reawakened The pope told the scientist that it was okay to study the evolution of the universe after the big bang, but they should not inquire into the big bang itself because that was the moment of creation and therefore the work of God.From my point of view, Stephen s search for the theory of everything is his inner search to meet and understand a real God His fascination with the universe leads his thoughts to the Hands of a creator that has put forward the laws that rule the cosmos So as to justify my idea for that, just take a look at his last words on this book if we do discover a complete theory we would know the mind of God So, what s the Theory of Everything Well, this is only a simple review and I don t like spoilers Do you really think I would give you everything PUN Read the book, I strongly recommend it and I guarantee it ll be BRIEF Larissa Fauber Click here to check Larissa Fauber s profile on Goodreads Click here to read Larissa Fauber s reviews This book is about theories of everything, really No, but nearly It tell us about theories in the universe, important scientific discoveries, facts and future development It s nice to read something like this It adds something to the general knowledge we know about the world and the universe we live in.
