    Now I read this book cover to cover, line-by-line, methodically going back over passages that were "challenging", line-by-line, got to the last page, closed the book and said out loud; "Nope, sorry Steve, you lost me there".

    Un libro muy difícil pero delicioso. Hawking muy Hawking, fiel a su estilo, con una narrativa no demasiado didáctica, con sus toques excéntricos que me disgustan pero hablando de temas de los que solo él y muy pocos más, contados con los dedos de la mano, pueden hablar. Que una mente así se abra para acercar temas tan controvertidos, interesantes y avanzados como los que trata es para agradecerlo. Este es de esos libros que cambian vidas. Así que Hawking, muchas gracias. De verdad.

    Hawking is an exceedingly clear and occasionally quite funny writer, not easy when the topic is quantum physics, etc. I would be lying if I claimed to understand much of this book, especially in the audiobook format in which an exceedingly pleasant British voice hurls a flood of Hawking's words and concepts, one more challenging than the previous one. It might, repeat: might, have been possible to understand this material on a printed page, which in this case included a lot of nifty diagrams, on Hawking is an exceedingly clear and occasionally quite funny writer, not easy when the topic is quantum physics, etc. I would be lying if I claimed to understand much of this book, especially in the audiobook format in which an exceedingly pleasant British voice hurls a flood of Hawking's words and concepts, one more challenging than the previous one. It might, repeat: might, have been possible to understand this material on a printed page, which in this case included a lot of nifty diagrams, on the presumption that repetition might have helped. But probably not. I did enjoy and generally understand the opening chapter in which Hawking explained the history of physics and our conception of the universe, with a beautiful presentation of the life and work of Einstein, and to a lesser extent his contemporaries and immediate intellectual followers. But after that, when Hawking moved into contemporary physics and the exploration of the cosmos (where he made his own contributions, mind you), I was mostly gasping for air, down for the count, you get the idea. Once I let go of the expectation that I could actually master the material, I kind of enjoyed the periodic appearance of concepts and phrases I had sort-of known about arrive in their natural and proper context, things like string theory, black holes, quanta, Heisenberg principle, nebula, etc. Perhaps more than anything, I enjoyed the ebulliance and delight with which Hawking presents his material, as if it is the simplest and most fun thing ever... which to him, it probably is.

    یکی از جذاب ترین و باحال ترین کتاب های علمی فیزیکی بود که خوندم و بسیار لذت بردم ازش. که چنتا از جذاب هاش رو دز زیر میارم: نسبیت خاص و عام انیشتین انیشتین در ابتدا میگفت که دلیل اینکه سیب روی سر نیوتن افتاد این بود که نیوتن و سطح زمین به سمت سیب شتاب گرفتند و انیشتین گرانش رو در ابتدا در نظر نگرفت.(که این نظریه نسبت خاص نامیده شد). بعدا انیشتین فهمید که اگر اینطور است که شتاب سطح زمین بسمت بالا باعث میشد که همه مردم به سمت بالا شتاب بگیرند ولی دید اینطور نیست و زمین تخت نیست بلکه گرد است، پس آمد یکی از جذاب ترین و باحال ترین کتاب های علمی فیزیکی بود که خوندم و بسیار لذت بردم ازش. که چنتا از جذاب هاش رو دز زیر میارم: نسبیت خاص و عام انیشتین انیشتین در ابتدا میگفت که دلیل اینکه سیب روی سر نیوتن افتاد این بود که نیوتن و سطح زمین به سمت سیب شتاب گرفتند و انیشتین گرانش رو در ابتدا در نظر نگرفت.(که این نظریه نسبت خاص نامیده شد). بعدا انیشتین فهمید که اگر اینطور است که شتاب سطح زمین بسمت بالا باعث میشد که همه مردم به سمت بالا شتاب بگیرند ولی دید اینطور نیست و زمین تخت نیست بلکه گرد است، ‌ پس آمد گفت که باید فضازمان پیچ و تاب بخورد و گرانش را به خمیدگی فضا زمان ربط داد ، یعنی این میدان گرانشی است که باعث خمیده شدن فضا زمان میگردد.که این نظریه نسبیت عام نام گرفت. سفر در زمان هاوکینگ میگه: یسری حلقه هایی تو زمان داریم که به حلقه های زمان معروفند یعنی جاهایی که بشه تو اونجاها با سرعت کمتر از نور حرکت کرد. و ویژگی این حلقه های زمان اینه که میشه تو اونها تو زمان سفر کرد. این از قسمت اثبات فیزیکیش، ولی تو عمل به دلیل پیچ و تاب فضا زمان(نظریه نسبت عام انیشتین) که اجازه ایجاد چنین حلقه هایی رو نمیده، پس در کل سفر در زمان در عمل کار محالی میشه و نیز در فیزیک چیزی داریم به اسمه ریسمان های کیهانی که تو خود این ریسمان ها سفر، بخصوص سفر به گذشته امکان پذیر نیست چون حلقه زمانی رو دربرنمیکیرن ولی اگه بشه فضاهای ریسمانی کیهانی پیدا کرد سفر به گذشته ممکنه که این کارم تقریبا محاله چون ویژگی این فضاها باید این باشه که بشه تو اونها با سرعت بیشتری از سرعت نور حرکت کرد که محاله:). اشتباه انیشتین در مورد زمین یا جهان انیشتین:جهان اینستاست بدون مبدا. درحالی که بعدا اثبات شد که جهان یا با منقبض شدن و یا با بزرگ شدنش پایان خواهد یافت(بستگی به ماده و انرژی دارد.) فرضیه های پایان جهان فرضیه های پایان جهان:یک اینکه اگر چگالی جهان از یک مقدار بحرانی بیشتر باشد، آنگاه در این حالت کشش گرانشی بین کهکشانها بیشتر شده و حرکت آنها را کند و درنهایت آنان را از دور شدن از هم باز می دارد.که در نهایت همه چی متراکم شده و همه چیز در یک ویرانگر گرانشی مکیده می شوند. ۲- دوم اینکه اگر مقدار چگالی از مقدار بحرانی کمتر باشد،آن گاه کشش گرانشی کمتر از آن است که بتواند از دورشدن کهکشانها نسبت بهم جلوگیری کند و ستارگان رفته رفته سوخت خود را تمام می کنند و در نتیجه در نهایت جهان رفته رفته تهی تر و سردتر می شود و دوباره مانند حالت اول همه چیز به پایان می رسد.اما در دوحالت هم جهان حداقل دو میلیارد سال عمر خواهد داشت. جهان در پوست گردو

    Stephen Hawking, stated in, " The Universe in a Nutshell" that our history is filled with infinite potentiality and what we "got” was due to disturbing the quantum field by our "observations." Profound, I thought, and pondered about his theory for months. To better understand Dr. Hawking's theory, I read everything on quantum physics I could understand and a pile of books on the brain, Bruce Hood's "The Self Illusion" was the most helpful. Below is what I believe correlates with Hawking's theory Stephen Hawking, stated in, " The Universe in a Nutshell" that our history is filled with infinite potentiality and what we "got” was due to disturbing the quantum field by our "observations." Profound, I thought, and pondered about his theory for months. To better understand Dr. Hawking's theory, I read everything on quantum physics I could understand and a pile of books on the brain, Bruce Hood's "The Self Illusion" was the most helpful. Below is what I believe correlates with Hawking's theory, It is from the book, The Nature of Personal Reality, by Jane Roberts, (Seth Material) I have included a quote and then how I am seeing life now through a magical lens. "An examination of your conscious thoughts will tell you much about the state of your inner mind, your intentions and expectations, and will often lead you to a direct confrontation with challenges and problems. Your thoughts, studied , will let you see where you are going. They point clearly to the nature of physical events. What exists physically existed first in thought and feeling. There is no other rule. What if our "observations" were first feeling-tone shared by all consciousness focused in physical reality. The cells and organs have their own awarenesses, and a gestalt one. So the race of man also has individual consciousness and a gestalt or mass consciousness of which makes up our physical reality. While physical we follow physical laws, or assumptions. These form the framework for corporeal expression. Within this framework you have full freedom to create your experience, your personal life in all of its aspects; the living picture of the world, your personal life, and to some extent your individual living experience, helped create the world as it is known in your time. It is important before we continue that you realize that consciousness is within all physical phenomena, however. It is vital that you realize your position within nature. Nature is created from within. The personal life that you know rises up from within you, yet is given. period. Since you are part of Being, then in a certain fashion you give yourself the life that is being lived through you." ~ Jane Roberts, Seth Material. “Although I cannot move and I have to speak through a computer, in my mind I am free.” ― Stephen Hawking When I fully realized my entire reality was created by me, and global consciousness, I could chose what to give my attention to for the change I wanted to see. The more you examine your thoughts and feelings the more excited you'll get when what you were thinking about appears. You'll notice "integrity" plays a role as well, (even when no one but you knows what good things you've done), because it's "liking yourself" that is most important in your ability to thrive without limitations. It only works if you truly believe. Just like Yoda said, “there is no try, only do.” Whatever you hold in your consciousness you put in your reality. If you are thinking about something, it will appear in a similar form. Don't get scared when you notice you have a lot of negative thoughts, about yourself and the world. These types of "thoughts" are your current vibration, giving you the reality you have now. Any change towards better inner-feelings about yourself and your surroundings will show up immediately in a in an event confirming your power to create your reality. I am now excited about cleaning up my thoughts -especially my deep inner feelings that were not as great as I wanted them to be. Below are examples of limiting beliefs you may want to remove. Example of limiting thoughts: 1. My behavior is hidden in my subconsciousness. 2. My life is a result of my childhood, or Karma, 3. Old age causes illness and regression. 4. People are out to screw me. Or People don't like me. 5. I am not smart enough, good enough, someone is better than me. 6. My religion is the right one, and so are my beliefs. 7. I have no control over the events in my life. 8. I am fat. 9. There is something wrong with money. People who have it are greedy, less spiritual than those who are poor. They are unhappier, and snobs. These are all beliefs held by many people. Those who have them will meet them in experience. Physical data will always seem to reinforce the beliefs, therefore, but the beliefs formed the reality. "The ego, which is ever changing based on a flow of new experiences looks out upon physical reality and surveys it in relation to those characteristics of which it is composed at any given time. It makes its judgments according to its own idea of itself." ~Jane Roberts I try to catch myself in conversation making jokes about myself, and stop it. ) When science has proven "consciousness creates everything in our reality" our focus will turn to beautiful stories, ideas and breathtaking environments. We will spot giving our attention to garbage news stories filled with violence and fear; because we don't believe what we hold these emotions in our consciousness mind. If I could ask Dr. Hawking one question it would be this: You said that we collapse waves when we observe an event. But what if-- our expectation collapsed the wave, our belief before the form existed. If this is true, consciousness is creating the collapsing of the field based on our inner-emotions, which would make the unpopular words, like "emotions, feelings and insights" the most valuable of all our senses. I learned most of my beliefs were secondhand and limiting, so I jumped those fences! I documented my journey in my memoir, "From Hollywood to God," by Kelly Granite Enck http://www.amazon.com/From-Hollywood-... I am leaving the link for those, like me, who love to explore the Inner Journey of the Mind! Thanks Stephen for all your years of passion! Love Kelly!

The First two chapters serve as a prerequisite for proper understanding. Short but very well explained introductory concepts of Einstein-Relativity stuffs; Maybe because i used to read a lot of books in that subject (I've read more books on relativity than automobile engineering in which I've got a bachelor's recently). Weirdness of Quantum Mechanics and its unification attempts with relativity at the initial conditions of the universe. Time and extra dimensions for the maintenance of consistencies. Some little dip in the chaos theory but too much idea regarding it in this book. Some chapters on his (and his colleagues) attempts on the formulations of the Quantum Gravity theory, then evolving into Super Gravity, then String theories and eventually m-theory atleast for now (Eventually is not the correct usage). Blackhole information paradox and the concepts of imaginary time are correlated to hinder the optimistic possibilities of Time Travel atleast for now. The Paradox is a puzzle resulting from the combination of quantum mechanics and general relativity. I feel personally that this Part needs revisiting again. Even the simple terms and explanations, these are much more complex topics undergoing tedious *theoritical* research currently. He also reassures the readers sarcastically that this might be a part of government cover up for Time Travel Conspiracy; You get to know only when you get to meet one like HG Wells. What I can assure is, that one could get a better view on string theory based M-theory which currently has the higher chance to become the Theory of Everything and the concepts of brane worlds. And that is my Review in a Nutshell.

    Yes, I'm a dork, and in addition to reading grammar books for fun, I also read science books. I've been told that Stephen Hawking is not as complicated to read as one might assume. While I did learn a lot from this book, I also was left with a lot more questions. Furthermore, the illustrations were either confusing or totally unnecessary.

    I really enjoyed A Brief History of Time and so was looking forward to The Universe in a Nutshell and its updated material. I was hoping it would be a "dumbed down" version of some of the high-end theoretical physics ideas that I haven't had the time or brain cells to keep up with. While I'm sure the content is dumbed down from Stephen Hawking's level, most of it is covered at a level and speed that kept it out of my comprehension.

I was hoping it would be a "dumbed down" version of some of the high-end theoretical physics ideas that I haven't had the time or brain cells to keep up with. While I'm sure the content is dumbed down from Stephen Hawking's level, most of it is covered at a level and speed that kept it out of my comprehension. To be honest I find a lot of modern theories and ideas very skeptical - it almost seems to me that the theories are created and given weight because they might be possible... and that's good enough because to prove otherwise is incredibly difficult. A part of me (no doubt remnants of thinking left there by my college professors) downplays my pessimism and wants to believe them at face value. In this book I was looking to confirm that part, but it just didn't happen. There didn't seem to be any real explanations or support (or maybe it was above my head and I zoned out). It was simply describing the theories (e.g., M Theory) and presenting them as fact. (We used to call this "hand waving" in my Physics classes in college - like a magician's hand waving as misdirection.) There were a lot of good parts that were interesting and engaging. Near the end there was a part on the evolution of life on Earth and humans that was really intriguing. It had to do with DNA as a form of evolutionary method of saving data which has now been augmented by humans' ability to store information outside of our DNA now. And I do now have a better understanding of the framework on some modern theories (like multi-dimensions) that I didn't have before. I particularly liked coming to a better understanding of the theory of our perception of reality being a mere projection of 4 dimensions (3d + time) that derives from a "real" existence that exists in a 5 dimensional "membrane" universe (much like a 3d object casts a 2d shadow). Cool stuff. Maybe I just need a bigger brain.

While it isn't that bad (it's actually very good), in comparison with Brief History, it seems only to have many more illustrations and fewer thorough explanations.

I don't know, I read too much about these kinds of things anyway so I guess I might not be right, it could be just what an intelligent layman without too much time needs. But that's a big maybe. Try it, after all, I put 4 stars up there for a reason.

    I do not yet have intellect enough to comprehend the entirety of the book. However, for the extent I managed to understand, I must say it was incredibly brilliant. I didn't begin the book with the expectation of thorough understanding, so there was no disappointment. Furthermore, it was actually a relief that I could get a lot of the stuff in the book considering the fact that it is written by Hawking. I am glad I gave it a try. I will boldly explore science non-fiction from now on. As for the wr I do not yet have intellect enough to comprehend the entirety of the book.

    We all owe a sacred debt to Stephen Hawking for his theories and contributions to physics. Approaching this book with a mild understanding of basic physics, I simply exhausted myself in his space-time, extra dimensions "Nutshell". The amount of energy it took to comprehend a fraction of what I read left me in a swirling vacuum fluctuation. It is an honor to have read Professor Hawking's book.

    Hồi xem Interstellar cảm thấy vô cùng mãn nhãn, nhưng chẳng có chút kiến thức gì về các hiện tưởng vật lý trong phim :)) nên tóm lại vẫn là chưa cảm nhận được hoàn toàn. Thế là tình cờ được một đứa bạn recomm: đọc quyển này đi, dễ hiểu cực kì. Quyết định đọc quyển này trước khi xem lại phim thêm lần nữa.

Thế là tình cờ được một đứa bạn recomm: đọc quyển này đi, dễ hiểu cực kì. Quyết định đọc quyển này trước khi xem lại phim thêm lần nữa. Có cảm tưởng như Stephen Hawking viết cuốn sách này không dành cho các nhà vật lí lí thuyết hay các nhà khoa học mà chủ yếu để dành cho những độc giả như mình, những người có hứng thú muốn tìm hiểu về những căn bản của vũ trụ mà trong đầu chưa có chút kiến thức cơ bản nào cả. Ngôn ngữ của ông được sử dụng vô cùng đơn giản, kể cả có thuật ngữ thì cũng được chú giải ở cuối sách để người đọc có thể dễ dàng nắm bắt. Không cầu kì, nhưng vẫn khiến mình cảm thấy choáng ngợp với những kiến thức, những sự thật mà mình chưa từng biết tới, là sự thật mà có vẻ còn khó tin hơn cả những điều hư ảo. Stephen Hawking quả thực đã viết cuốn sách này với tất cả niềm đam mê vật lí trong ông, một giọng văn hài hước đầy cuốn hút. Mình thích nhất là chương sách ông viết về Hố đen, Kì dị Big Bang và Hình dạng của thời gian. Chương đầu thì ngập trong lí thuyết, quả thực là mình cũng chưa đủ trình để ngấm đc :)) có cảm giác nếu ngày xưa chăm học lí hơn thì giờ đọc quyển này sẽ cảm nhận đc nhiều cái hay hơn.

    یک برآمد بسیار مهم نسبیت رابطة بین جرم و انرژی است. ادعای آلبرت انیشتین که سرعت نور باید برای تمام ناظران یکسان باشد ایجاب میکند که هیج چیز نمیتواند تند تر از نور حرکت کند. در نتیجه استفاده از انرژی برای شتاب دادن هر چیز چه ذره باشد و چه سفینه فضائی، بر جرمش میافزاید و کار بیشتر را سخت تر میکنند. شتاب دادن یک ذره تا سرعت نور ناممکن خواهد بود. زیرا مقدار بینهایت انرژی لازم خواهد داشت. جرم و انرژی معادل هستند. آن طور که در فرمول معروف اینشتاین خلاصه شده است: E=MC ۲ میتوان گفت این معادله در فیزیک، یک برآمد بسیار مهم نسبیت رابطة بین جرم و انرژی است. ادعای آلبرت انیشتین که سرعت نور باید برای تمام ناظران یکسان باشد ایجاب می‌کند که هیج چیز نمی‌تواند تند تر از نور حرکت کند. در نتیجه استفاده از انرژی برای شتاب دادن هر چیز چه ذره باشد و چه سفینه فضائی، بر جرمش می‌افزاید و کار بیشتر را سخت تر می‌کنند. شتاب دادن یک ذره تا سرعت نور ناممکن خواهد بود. زیرا مقدار بی‌نهایت انرژی لازم خواهد داشت. جرم و انرژی معادل هستند. آن طور که در فرمول معروف اینشتاین خلاصه شده است: E=MC ۲ می‌توان گفت این معادله در فیزیک، تنها معادله‌ای است که زبانزد خاص و عام است. در میان برآمدهای آن، درک این بود که اگر هسته یک اتم اورانیوم شکافته و به دو هسته با جرم‌های تقریباً کمتر تقسیم شود، انرژی بی اندازهٔ زیادی تولید خواهد کرد.

    It was my first ride with Stephen Hawking , and it wasn't bad at all. Reading about your UNIVERSE for the first time, in such a detailed explanation for what the writer aims to tell based on his wide knowledge in Quantum mechanics, theoretical physics and cosmology , necessarily requires a knowledgeable reader in the sciences I've just mentioned so he/she wouldn't be perplexed and then, he would get answers for many questions that may flash in his mind.

In addition to the diverse information that one can get from reading this , he quietly doesn't get bored due to Hawking's sense of humor. It is highly recommended for those who care much about the universe and its studies.

    This is my first time ever audio book. It is enjoyable, esspecially because of the voice - is calm. I am used to listening to scientific materials, most of them in form of debates. But listening to an audio book is nothing compared to reading - you cannot turn back the page or re-read a passage, you cannot make notes with a pencil on the page, you cannot highlight key definitions, aseertions, or conclusions in the text. Eye-sight is also a much more efficient tool in gathering information than t This is my first time ever audio book. It is enjoyable, esspecially because of the voice - is calm.

    به بهانه درگذشت نویسنده کتاب تصمیم گرفتم برای خودم یک ریوی بنویسم. جز اولین کتاب های انتخابی من از نمایشگاه کتاب بود در دوره راهنمایی. اون موقع خیلی این کتاب صدا کرده بود و برای ما بچه های عشق نجوم و فیزیک فوق العاده بود. هیچ وقت یادم نمیره وقتی توضیحات کتاب رو راجع به سیاه چاله ها رو خونده بودم چقدر شگفت زده شده بودم و تا مدت ها بهش فکر میکردم. هر چند خیلی جاهای کتاب برای من سخت و غیر قابل فهم بود اما باز هم یاداوری زمان خوندن کتاب برای من خیلی لذت بخشه

    Simply, I love the way of Stephen Hawking in explaining his beliefs and knowledge, I think he's the most smartest man living on earth right now. In every chapter of his books he's showing us a great review about the universe. In this book I was surprised that he can easly explains how biology works as well. My next book written by his is A briefier History of Time

    Un libro sencillo y dinámico. Lo disfruté mucho. Se aprende acerca de astronomía, física, universo, mecánica cuántica, viajes en el tiempo y evolución.

    Wie auch sein Vorgänger - ein Buch, das jeder im Schrank haben sollte.

    Cuốn sách nên đọc thay vì lên mạng phí thời gian cho những thứ nhảm ruồi tào lao về UFO.

    Ha Hawking-ot olvasok, akkor elmélyülök mélyen a gondolataimba, önkéntelenül is elkezdek filozofálni az élet mibenlétéről, a halálról, a jövőről, a múltról, minden olyan témáról, elvről, amiről a szürke hétköznapokban nem tudok elábrándozni, mert olyankor egyszerűen benne vagyok egy végtelen mókuskerékben. (Jobban belegondolva, egy mókuskerék általában végtelen, szóval előtte a végtelen jelző legfeljebb nyomatékosításra szolgált.) De apropó végtelen. Hawking külön figura, felszentelte az életét Ha Hawking-ot olvasok, akkor elmélyülök mélyen a gondolataimba, önkéntelenül is elkezdek filozofálni az élet mibenlétéről, a halálról, a jövőről, a múltról, minden olyan témáról, elvről, amiről a szürke hétköznapokban nem tudok elábrándozni, mert olyankor egyszerűen benne vagyok egy végtelen mókuskerékben. (Jobban belegondolva, egy mókuskerék általában végtelen, szóval előtte a végtelen jelző legfeljebb nyomatékosításra szolgált.) De apropó végtelen. Hawking külön figura, felszentelte az életét arra, hogy az egyszerű ember nappalijába, hálószobájába eljuttasson egy kis szeletet a tudásából, amely kis szelet mégis a végtelen akar lenni. A Tér teret alkot, az Idő időt, együtt pedig megalkotják a téridőt, melyben élünk, érzékelünk, létezünk, azonban, mióta öntudatra ébredtünk, kiszakadtunk a végtelen mókuskerékből, kíváncsiak vagyunk a miértekre is. öröktől fogva létezett az a kerék? Ha létezett, öröktől fogva forog, vagy később indította be valaki? A kerékkel együtt, öröktől fogva létezett benne a mókus, vagy valamikor megjelent? És hogyan jelent meg, miért? Forgott az a kerék a mókus nélkül is? Vagy a mókus mozgása pörgette meg?
