There is a very real danger that we will kill everything on this planet now that we have the technological power to do it.
Although we believe that we can choose what we do, our understanding of the molecular basis of biology shows that biological processes are governed by the laws of physics and chemistry and, therefore, are as determined as the orbits of planets.
When I find out about Schrodinger’s cat, I reach for my gun.
If what we consider real depends on our theory, how can we make reality the basis of our philosophy? … But we can not distinguish what is real from the universe without a theory … it makes no sense to ask if it corresponds to reality, because we do not know what is the independent reality of a theory.
I do not believe that the human race will survive the next thousand years, unless we disseminate to space. There are too many accidents that can happen to life on a single planet. But I am an optimist. We will approach the stars.
Because there is a law like gravity, the Universe can and will be created from nothing. Spontaneous creation is the reason why there is something more than nothing, why the Universe exists, why we exist. It is not necessary to invoke God to turn on the blue tactile paper and start the Universe.
We could call to order by the name of God, but it would be an impersonal God. There is not much personnel about the laws of physics.
The initial configuration of the universe may have been chosen by God, or it may have been determined by the laws of science. In any case, it would seem that the whole universe would be determined by evolution according to the laws of science, so it is difficult to see how we can be masters of our destiny.
Therefore, intelligent beings in these regions should not be surprised if they observe that their locality in the universe satisfies the conditions that are necessary for their existence. It’s a bit like a rich person who lives in a wealthy neighborhood without seeing poverty.
When one’s expectations are reduced to zero, one really appreciates everything one has
All that my work has shown is that you do not have to say that the way the universe began was the personal whim of God.
Speech has allowed the communication of ideas, allowing human beings to work together to build the impossible. The greatest achievements of mankind were achieved by speaking, and their greatest failures by not speaking. It does not have to be this way. Our greatest hopes could become a reality in the future. With the technology at our disposal, the possibilities are unlimited. All we have to do is make sure we keep talking.
I have lived with the prospect of an untimely death in the last 49 years. I’m not afraid of death, but I’m not in a hurry to die. I have so much that I want to do first. I believe that the brain is a computer that will stop working when its components fail. There is no heaven or life after broken computers; That’s a fairy tale for people afraid of the dark.
All my life, I have been fascinated by the big questions we face and we have tried to find scientific answers for them. If, like me, you have looked at the stars and you have tried to make sense of what you see, you have also begun to ask yourself what makes the universe exist.
Many prizes have been awarded for showing that the universe is not as simple as we might have thought.
The world has changed much more in the last 100 years than in any other century of history. The reason is not political or economic but technological: technologies that flow directly from advances in basic science. Clearly, no scientist represents these advances better than Albert Einstein: Person of the century of TIME.
We will not know for a few years.
I believe that the next [21st century] will be the century of complexity. We have already discovered the basic laws that govern matter and understand all normal situations. We do not know how the laws fit, and what happens under extreme conditions. But I hope we find a complete unified theory sometime in this century. There is no limit to the complexity we can build using those basic laws.
One does not have to appeal to God to establish the initial conditions for the creation of the universe, but if he does, he would have to act through the laws of physics.
The universe and the Laws of Physics seem to have been designed specifically for us. If one of the near 40 physical qualities had more than slightly different values, life as we know it could not exist: either the atoms would not be stable, or would not combine into molecules, or the stars would not form heavier elements, or the universe would collapse before life could develop, and so on …
You can not predict the future.
Or in other words, why does the disorder increase in the same direction as the universe expands?
I believe that the long-term future of the human race must be space and that it represents an important life insurance for our future survival, since it could prevent the disappearance of humanity through the colonization of other planets,
The human error that I would most like to correct is aggression,
I do not believe in a personal God.
Science will win because it works.
Think of our DNA. In the last million years, our DNA has not changed at all. It is really very similar to what it was in the jungle, a million, two million years ago. But in the last 200 years, our destructive capacities have increased many millions of times. Why do not we see smart signals from outer space? Because in all probability, once civilization reaches the point where our civilization has arrived, it destroys itself.
It often happens that I have an idea, but then I try to complete the intermediate steps and see that they do not work, so I have to give it up.
Someone told me that every equation that I included in my book would reduce sales by half. I put in an equation, the famous Einstein equation, E = MC squared. I hope this does not scare half of my potential readers.
Why do we remember the past, but not the future?
There is no way we can predict the weather six months in advance beyond giving the seasonal average
Physics as we know it will end in six months – Max Born
It is the gravity that shapes the large-scale structure of the universe, even though it is the weakest of the four categories of forces
In his eyes shone the reflection of the most beautiful planet in the Universe: a planet that is not too hot or too cold; that has liquid water on the surface and where gravity is perfect for humans and the atmosphere is perfect for them to breathe; where there are mountains and deserts and oceans and islands and forests and trees and birds and plants and animals and insects and people, lots and lots of people. Where there is life Some of that, possibly, intelligent.
I have experimental evidence that traveling in time is not possible.
I think the simplest explanation is that there is no God. Nobody created the universe and nobody directs our destiny. This brings me to a deep understanding that there probably is no heaven or life after death. We have this life to appreciate the great design of the universe and for that, I am extremely grateful.
Simplicity is a matter of taste
Scientists tend to risk theories they admire
The 10-dimensional idea may seem exciting, but it would cause real problems if you forget where you parked your car.
We believe that humans have existed only for a small fraction of cosmic history, because the human race has improved so rapidly in knowledge and technology that if people had existed for millions of years, the human race would be much more advanced in their domain.
If you are lucky enough to find love, remember that it is there and do not throw it away.
Because imaginary time behaves like another direction in space, stories in imaginary time may be closed surfaces, like the surface of the Earth, with no beginning or end [existential].
God not only plays dice, but throws them into the corner where you can not see them.
In real time, the universe has a beginning and an end in the singularities that form a limit to spacetime and in which the laws of science are broken.
I am the archetype of a disabled genius, or should I say a genius physically challenged, to be politically correct. At least I am obviously physically challenged. If I am a genius, it is more open to doubt.
While there is life there is hope.
Eternity is a long time, especially towards the end.
We do not allow animals to suffer, so why humans?
The quietest people have the loudest minds.
The human capacity for guilt is such that people can always find a way to blame themselves
Each one of us exists for a short time, and in that time we explore only a small part of the entire universe
Then, when people ask me if I believe that God created the universe, I tell them that the question itself does not make sense. Time did not exist before the Big Bang, so there is no time for God to make the universe enter. It’s like asking for directions to the edge of the earth; the earth is a sphere, it does not have an edge, so looking for it is a futile exercise.
Remember to look towards the stars and not down at your feet. Try to make sense of what you see and ask yourself about what makes the universe exist. Be curious. And although life may seem difficult, there is always something you can do and be successful. It’s important that you do not give up.
Not leaving planet Earth would be like shipwrecked on a desert island that does not try to escape … Sending humans to other planets … will shape the future of the human race in ways we do not yet understand, and can determine whether to have a future at all.
The human race should not have all its eggs in a single basket, or on a planet. Hopefully we can avoid dropping the basket until we have distributed the load.
Although quantum mechanics has existed for almost 70 years, it is still not generally understood or appreciated, even by those who use it to make calculations.
As you know who have seen Jurassic Park, this means that a small disturbance in one place can cause a major change in another. A butterfly flapping its wings can cause rain in Central Park, New York. The problem is that it is not repeatable. The next time the butterfly flaps its wings, a number of other things will be different, which will also influence the weather. That’s why weather forecasts are unreliable.
The universe does not behave according to our preconceived ideas. It continues to surprise us.
If there really is a complete unified theory that governs everything, presumably it also determines your actions. But he does it in a way that is impossible to calculate for an organism that is as complicated as a human being. The reason we say that humans have free will is because we can not predict what they will do.
The human error that I would most like to correct is aggression. It may have had a survival advantage in caveman days, to get more food, territory or a couple to breed with, but now threatens to destroy us all.
We are in a disconcerting world. We want to make sense of what we see around us and ask: What is the nature of the universe? What is our place in it and where did it come from and where did we come from? Why is it like this?
Disability does not need to be an obstacle to success.
I prefer to be right than rigorous.
The Simpsons are the best on American television.
If [the universe]expanded very slowly, the force of gravity would cause it to finally stop expanding and then begin to contract. However, if it expanded to more than a certain critical index, the gravity would never be strong enough to stop it, and the universe would continue to expand forever.
Now we are all connected by the Internet, like the neurons in a giant brain.
Many people do not like the idea that time has a beginning, probably because it smells like divine intervention.
Thirty years ago I was diagnosed with a motor neuron disease and I was given two and a half years of life. I’ve always wondered how they could be so precise about half.
I’ve sold more physics books than Madonna about sex. [Hawking adopted this statement from an observation made by his former post-doc, Nathan Myhrvold.]
[Question: Do you think that scientists correct themselves as often as they should?] More often than politicians, but not as often as they should.
[Question: What do you think was the most important idea of physics that came up this year?] We will not know for a few years.
It is reasonable to ask who or what created the universe, but if the answer is God, then the question has simply been diverted to who created God.
I’m damned if I’m going to die before having untangled more of the universe
The deep desire for knowledge of the humanities is sufficient justification to continue our search. and our goal is nothing less than a complete description of the universe in which we live.
Someone told me that every equation that I included in the book would cut sales by half. Therefore, I resolved to have no equation at all. In the end, however, I put in an equation, the famous Einstein equation. I hope this does not scare half of my potential readers.
There are reasons for cautious optimism that we can now be near the end of the search for the ultimate laws of nature.
There is no prescribed route to follow to arrive at a new idea. You have to take the intuitive leap.
If you understand how the universe works, you control it in some way.
Only a few would allow the existence of creatures like us. Therefore, our presence selects from this wide range only these universes that are compatible without existence. Although we are insignificant and insignificant in the scale of the cosmos, this makes us a sense, the lords of creation.
It is impossible to imagine a space of four dimensions. Personally, I find it quite difficult to visualize a three-dimensional space.
There are no black holes, in the sense of regimes from which light can not escape to infinity. However, there are apparent horizons that persist for a period of time.
One of the basic rules of the universe is that nothing is perfect. Perfection simply does not exist ….. Without imperfection, neither you nor I would exist
Since the dawn of civilization, people have not been content to see events as unrelated and inexplicable. They have yearned for an understanding of the underlying order in the world. Today we still long to know why we are here and where we come from. The deepest desire for knowledge of humanity is a sufficient justification for our continuous search. And our goal is nothing less than a complete description of the universe in which we live.
Although I can not move and I have to speak through a computer, in my opinion I am free.
Please join me in applauding ESA: the historic efforts of the European Space Agency with the Rosetta Mission and the landing of a rotating spacecraft. It may seem a work of fiction, but it is very real, very impressive, and will help us to discover even more the mysteries surrounding the formation of the solar system. They made a beautiful short movie using an imaginary landscape to illustrate today’s historic feat.
[AI] would take off alone and be redesigned at an increasing rate. Humans, who are limited by slow biological evolution, could not compete and would be replaced.
It is clearly possible that something acquires greater intelligence than its ancestors: we evolved to be more intelligent than our ape ancestors, and Einstein was more intelligent than his parents.
Everyone can enjoy a luxurious leisure life if the wealth produced by the machine is shared, or most people can end up miserably poor if the owners of the machine successfully lobby against the redistribution of wealth.
A picture is worth a thousand words … and it consumes a thousand times more memory.

Every man should marry. After all, happiness is not the only thing in life.
The wise never get married, and when they get married they become the opposite.
Success is a relative term. Bring so many relatives.

The more you learn, the more you know. The more you know, the more you will forget. The more you forget, the less you know. So, why bother to learn?
Once I cried because I did not have shoes. Then I met a man without feet, so I took his shoes. I mean, it was not like I was going to need them.
I can contradict myself, but at least I do not contradict myself.
I am very easy to understand once you see it my way.
