Humans live on in their influence, and in their children, he wrote. Even though Hawking said he didn't believe in a personal God, if there was one, the scientist said, he had a question for Him. M-theory is a theory in physics that unifies all consistent versions of superstring theory. It's probably not the question most other people would ask a Supreme Being, but then, Hawking was one of a kind.
In the book, Hawking answers other major questions, such as whether we can predict the future in principle yes, in practice no , if time travel is possible he can't rule it out , and if there's other intelligent life in the universe yes. Eddie Redmayne, who played Hawking in the film The Theory of Everything , wrote the book's foreward.

He relates that before Hawking saw the movie, he told the actor he would be honest with his review, whether it was "Good. Or otherwise. Be respectful, keep it civil and stay on topic. We delete comments that violate our policy , which we encourage you to read. The idea goes as follows: Quantum mechanics implies that space is filled with particles and anti-particles - which are constantly appearing in pairs, separating, them coming together again and annihilating each other.
In the presence of a black hole one member of the pair may fall into the black hole, leaving the other member without a partner to engage in mutual annihilation. This particle or anti-particle may escape as 'radiation' from the black hole. Sketches depicting Hawking Radiation Scientists speculate that, unless a black hole gains mass by engulfing other objects , it will eventually vanish. I'll give a brief synopsis of his responses, and leave you to read the book if you want more information. Everything can be explained by the laws of nature.
Matter and energy and space were spontaneously created by the Big Bang. This is a meaningless question because there was no 'before' the Big Bang. Time actually spacetime was created BY the Big Bang. It's like asking 'what is south of the South Pole? We don't know yet but Hawking likes to think there are other forms of intelligent life out there. They just haven't contacted Earth In any case, meeting an advanced civilization would be unadvisable for us. Remember European settlers and American Indians? If aliens came here it would be like the film 'Independence Day.
The Heisenberg Uncertainty Principle dictates that we can't know both the position and momentum of a particle at the same instant.
Thus we can't predict what will happen to a particle or things made of particles at a future time. A black hole - which is single point of infinite density - is a star that's exhausted its nuclear fuel and collapsed Theoretically yes. If spacetime was warped enough to form a loop, time travel would be possible. However, it time travel WAS possible, someone from the future would probably have come back to visit us already.
Could Stephen Hawking have studied in Germany?
In , Hawking held a party for time travelers in his college at Cambridge, for a film about time travel. No one came. Not forever. Nuclear war is a dire threat and there will be a meteorite strike at some point. Moreover, global warming is likely to make Earth uninhabitable, since our climate could become like that of Venus - boiling hot and raining sulfuric acid.
By then I hope and believe that our ingenious race will have found a way to slip the surly bonds of Earth and will, therefore, survive the disaster. The same of course may not be possible for the millions of other species that inhabit the Earth, and that will be on our conscience as a race. In order to survive long term, humans need to colonize other planets. This won't be cheap. Hawking helped initiate a research and engineering project called 'Breakthrough Starshot", which strives to develop spacecraft capable of reaching the star system Alpha Centauri - which is 4. Hawking believes that in the next hundred years humans will be able to travel to the inner planets of the solar system and in years we will have visited the nearest stars.
Breakthrough Starshot - What are the prospects that scientists will unite Einstein's theory of relativity and quantum theory to achieve a complete theory of the laws of the universe? This will happen within the next millennium. Computers are likely to overtake human intelligence in the next years. Thus we need to ensure that computers have goals in line with ours.
Just to be safe, robotic designs should always incorporate a 'kill switch. The development of fusion power to give an unlimited supply of clean energy. It would be an inexhaustible supply of energy without pollution or global warming. It can be done. View all 9 comments. Dec 10, Jenna rated it it was amazing Shelves: science.

These and other questions are answered with brief, simple explanations. Steven Hawking's brilliance shines through on every page. His wittiness is prevalent throughout the book as well including some wonderful jabs at Donnie-johnnie Trump. Suffice it to say, Mr. Hawking was not a fan! I absolutely loved this book. I only wish it could have been longer. Steven Hawking was such a gift to humanity, his genius will live on for as long as there is intelligent life to appreciate his many contributions.

I was disappointed, but not surprised, because I had shown that if general relativity is correct and energy density is positive, time travel is not possible.
I would have been delighted if one of my assumptions had turned out to be wrong. I'm not really asking a question - a lot of what Hawking talks about really isn't even theoretically testable. Theoretical physics does tend in that direction - often it talks about ideas that are not testable yet, and may not be for a long time, or which are mathematical speculation as much as observation.

The afterword by his daughter Lucy is touching including mentioning the impact he had on people as could be seen by the large crowds which quietly lined the street on his passing. He goes on to discuss how time itself started with the big bang and the universe, and well-defined laws of nature mean there is nothing for a God to do.

You may agree, partly agree or disagree with his views, but he certainly offers a lot of food for thought. The next topic is on how it all started with the big bang. While all the answers are yet not there, Hawking is confident that physics will crack the puzzle of how the universe sprang from nothing. There is already a lot of progress made such as with M-theory. The section on black holes is probably the most detailed and it is also a bit dense in parts.
This is probably the area Stephen Hawking has contributed the most, and I suppose that explains the level of detail. The discussion is fascinating — do black holes retain context and information of what goes in? How do they come about, and how can study them? In the discussions around climate change, and in fleeting references in other sections as well, Hawking stresses that we are being very irresponsible with respect to Planet Earth, and people in power had better pay attention to this. The other sections on space travel, AI make for interesting reading as well.
A great book to start the year — very intellectually stimulating. My rating: 4. View all 4 comments. Oct 22, Lou rated it really liked it.

One of the things I most appreciate about him and his books is that he makes often complex and complicated topics accessible to everyday individuals such as myself - those without a background or degree in the sciences, and here he explores some of the biggest and most important unanswered questions hence the title in a way that is understandable to all and doesn't require expert or previous knowledge on said topics.
I am sad that no more of his fantastic works can now be published, and I have huge respect for him as although he certainly had some challenging obstacles to overcome he has contributed so much to what we now know which is more than most of us will achieve in this life - the word inspirational is what immediately comes to mind. A thoroughly engaging, intriguing and enjoyable romp through Hawking's opinion on age-old, philosophical questions right through to some of those at the forefront of current affairs.

I loved hearing his theories about our future and I agree with a lot about what he has to say about religion and how human fascination with science and space travel is so important for our future.
I really agree with that statement about having all "Unleash your imagination. I really agree with that statement about having all our eggs in one basket and how it's important for us to find a new home. Religion was an early attempt to answer the questions we all ask: why are we here, where did we come from?
Long ago, the answer was almost always the same: gods made everything. The world was a scary place, so even people as tough as the Vikings believed in supernatural beings to make sense of natural phenomena like lightning, storms or eclipses. Nowadays, science provides better and more consistent answers, but people will always cling to religion, because it gives comfort, and they do not trust or understand science. I will admit some if it went way over my head with the mathematics and equations and quantum physics but I did my best and I feel like I learned a lot while reading this.

A total page-turner, this book is quite remarkable it gives you a sense of a personal interview between Dr. Hawking and the reader. The Big questions are: Is there a God? What is inside of a black hole? Can we predict the future? Will we survive on earth? I highly recommend this book. View 1 comment. Part of the legacy of an exceptional genius, a source of inspiration and a science communicator. Please note that I have put the original German text to the end of this review. Just if you might be interested. Hawking understood how to use his life in many ways in exemplary fashion, despite his adverse health, and to research with full vigor.
He was an inspiration to millions of people despite all the restrictions. And he used the nimbus as a genius, who is caged in his body, to achieve that goal. The press loved Hawking and he played with the media channels like a virtuoso. He was for understandable and entertaining science journalism away from the academic ivory tower. Far away from academics who fail because of their inability to explain their theses understandably and rousingly. And feast themselves on their lonely genius instead. Hawking wanted to make science accessible to the masses of people, fueling joy and enthusiasm, inspiring a new generation of researchers.
The generation of bloggers known in the new media, Youtubers, etc. His unusual life enabled him to gain a reputation he probably would never have attained to that extent. And he was an inspiring model to all procrastinating, passive, blaming, quarreling, How ridiculous is it when healthy people wallow in their self-pity or are unable to control their emotions.
A quick look at the philanthropy and kindness of an exceptional explorer like Hawking would suffice. To shamefully take consequences and prioritize self-discipline, in order not to stagnate further. Concerning the ideological aspects of Hawking's work, every reader has to find his own approach. Hawking's metaphysical hypotheses permeate his work and are relevant to readers who are not only interested in pure science.
As well as his political analyzes and warnings. In addition to inspirational quotes, Hawking also left warnings of various, future dangers. Both should be used in the sense of a productive use of his legacy. The wisdom of his mantras and the pessimism of his warnings of AI and alien intelligences.
The safety of AI depends on two factors: human competence and computer security. That sounds very frightening, but it should work in practice because a lot of infrastructures depends on it. But as long as capable programmers implement sufficient security mechanisms to never provide the AI with too much power and access rights, this danger is eliminated. And if these KIs are sufficiently protected against infiltration and sabotage, its fatal manipulation and misappropriation can be prevented.
The only problem is that autonomous physical and purely virtual weapons systems need a lot of self-sufficiency and networking to work "well. This will be a balancing act. Hopefully, nobody will stumble over the Terminator. The extraterrestrial intelligences are a different caliber and no approach is consistent.
One can optimistically run to ruin or pessimistically pursue isolationism. Each option has its advantages and disadvantages. In Hawking's opinion, we would do well to behave as inconspicuously as possible and quietly evolve as quickly as possible. And in as little space as possible with fewer signals, emissions and detectable activities on just a few planets. This would entail restrictions on the use of new communications capabilities that are yet to be developed, space colonization, asteroid mining, and so on — all key technologies for the further development of humanity.
For economic reasons, one will take all risks and expand as far as technically possible forever until it becomes clear which assumption was correct. There is a contradiction between Hawking's urge for space colonization with self-sufficient settlements with independent populations and his warning to be unobtrusive. Both are not possible at the same time. Humanity will gamble and hopefully win. The dangers of improving humans through genetic engineering and implants are small footnotes in relation to machine apocalypse or alien invasion. China has most likely already begun and everyone else will follow.
As always, "It's the economy, stupid. It would be hypocritical now to pretend that immediate improvement and gene optimization would make a difference and break the taboo. Much ideology plays into it. The poverty that arises from the lack of distributive justice is the problem. And not whether the one human is breathing with gills underwater and lives years or forever and the other with fewer enhancements can only live years and can afford a little less intelligence increase.
There is no difference to today. For Hawking, the easily preventable diseases of civilization are incomprehensible. That so many people fail to get up regularly from sitting, eat less and move their lazy posteriors. Instead of just eating from 7 to 22 and not moving at all.
Because it really is not rocket technology to get some ambitions not to die earlier because of stupid and preventable reasons. The criticized hostility to science will become another embarrassing footnote in history. One just has to sit out the time and mindfully avoid dealing with such channels. Prefer to actively participate in the dissemination of knowledge and the passing of the torch to the youth.
Because with personified stupidity, ignorance, counseling resistance and lack of learning ability cannot be discussed. Therefore, it would be lost love and waste of time even to seek dialogue with such individuals engaging in those political agendas. Neither of both sides would benefit from it. Especially now that research is opening up more doors than ever before, a healthy mix of caution and curiosity is required.
One never knows what one awakens. Be it in machines, unstoppable processes or in the vastness of space. Hawking verstand es, sein Leben trotz widrigen Gesundheitszustandes in vielfacher Weise vorbildhaft zu nutzen und voller Elan zu forschen. Die Presse liebte Hawking und er spielte auf ihre wie ein Virtuose. Auch die Generation der in den neuen Medien bekannten Blogger, Youtuber, etc. Hinsichtlich der ideologischen Aspekte in Hawkings Werk muss jeder Leser seine eigene Herangehensweise finden.
Gleich wie auch seine politischen Analysen und Warnungen. Wie auch alle logistischen, wirtschaftlichen und prozesstechnischen Anwendungen. Bis sich zeigt, welche Annahme richtig war. Viel Ideologie spielt da mit hinein. Und nicht, ob der eine Mensch mit Kiemen unter Wasser atmen und Jahre alt werden und der andere "nur" halb so alt wird und sich etwas weniger Intelligenzsteigerung leisten kann.

As the final parting gift from one of the modern legends of scientific genius and embodiment of human perseverance, I couldn't give this anything less than 5-stars. From the existence of God and other intelligent life in the universe, to time and space travel, and whether we will survive on Earth, or will artificial intelligence outsmart humans - Hawking's addressed these issues in his usual authentic, direct and honest manner.
While there are some hard science smattered throughout the narrative, especially when the topic centred around cosmology, a substantial chunk of the writing can be easily comprehended without requiring a physics degree. I believe this is a book which should be read by everyone as it tackles some really pressing issues about the future of humanity. We spend a great deal of time studying history, which, let's face it, is mostly the history of stupidity. So it's a welcome change that people are studying instead the future of intelligence.
We are aware of the potential dangers, but perhaps with the tools of this new technological revolution we will even be able to undo some of the damage done to the natural world by industrialisation. Even though the book was meant to be as exoteric as possible, it is still rather thorough for the general public.
To me, the answers were prolix and discursive.
Much explaining was done, but I often found myself asking "How's that relevant to the question?

Is Time Travel Possible? Will We Survive on Earth? In reality, this book is bigger on the inside.
It teaches us again to ask bold, big questions — something which seemed perfectly fine for us when we were children and makes us look like dilettantes uttering nonsense now. It kindly reminds us of our endless possibilities no matter how restricted by circumstances we feel. It shows us the infinite beauty of things which are much bigger than our understanding and much older that anything we can possibly imagine for comparison.
It tells us stories of stars that died unbelievably long ago and stars that are living so far we most likely will never see them. And, first and foremost, it tells the story of a boy who passionately, without cease, asked questions and refused to believe in boundaries. Instead, he believed in endless possibilities if not of a single human being, then of the curious, smart and brave generations to come. May 11, Jack Chaucer rated it it was amazing.

One of the easiest 5 stars rate I had to give! I mean I loved it. While reading the book I was fascinated and intimated. Reading a tiny piece of his mind is and will always be fascinating! It was such an easy book to read. No need to be a science nerd like in The Big bang Theory to enjoy that book. He is easy to understand and should we talk about his sense of humour? I don't think so but I laughed so much! Oct 20, Richard rated it it was amazing. Hawking was a genius.
His research and "So remember to look up at the stars and not down at your feet. His research and ideas have forever changed how we see and know the universe around us. His theories on Black Holes have changed Cosmology as much, or more, that the ground breaking works by Galileo and Einstein.
His ideas and theories will effect his field forever but it is his personality and drive that we should also not forget. Despite being told in his early twenties that he wouldn't live more than another five years, due to Motor Neuron Disease, Hawking set forth and continued towards his educational, career, family and personal goals and lived another fifty years, succeeding even beyond his own wildest dreams.
In this book, Hawking gives us his thoughts and ideas on ten "big questions" including; god, other intelligent life in the universe, time travel, the need to colonize space, and artificial intelligence. He writes in a manner that presents the science in a way that is both easy to understand and that shares his personal thoughts and feelings.
Hawking pointed out that science is currently out of favor with the general public and that this will prove to be a large problem for both individuals and society as a whole. He presents some ideas on how to get people more excited about both science and how it will effect the world. I think reading this book would be a good start. Nov 28, Brian Bakker rated it liked it.
