Stephen Hawking
The universe doesn't allow perfection.Collection: Perfection
There should be a better way to start a day than waking up every morning.Collection: Morning
The idea of 10 dimensions might sound exciting, but they would cause real problems if you forget where you parked your car.Collection: Real
I may contradict myself, but at least I don't contradict myself.Collection: May
What I have done is to show that it is possible for the way the universe began to be determined by the laws of science. In that case, it would not be necessary to appeal to God to decide how the universe began. This doesn't prove that there is no God, only that God is not necessary.Collection: Religious
Mankind's greatest achievements have come about by talking and its greatest failures by not talking. It doesn’t have to be like this.Collection: Talking
Without imperfection, you or I would not exist.Collection: Imperfection
Save water. Shower with your girlfriend.Collection: Girlfriend
When I hear of Schrödinger's cat, I reach for my pistol.Collection: Cat
A snooze button is a poor substitute for no alarm clock at all.Collection: Buttons
Science can explain the universe without the need for a Creator.Collection: Needs
While there's life, there is hope.Collection: Hope
So long as the Universe had a beginning, we could suppose it had a creator. But if the Universe is really completely self-contained, it would have neither beginning or end, it would simply be. What place then for a creator?Collection: Science
One can see from space how the human race has changed the Earth. Nearly all of the available land has been cleared of forest and is now used for agriculture or urban development. The polar icecaps are shrinking and the desert areas are increasing. At night, the Earth is no longer dark, but large areas are lit up. All of this is evidence that human exploitation of the planet is reaching a critical limit. But human demands and expectations are ever-increasing. We cannot continue to pollute the atmosphere, poison the ocean and exhaust the land. There isn't any more available.Collection: Ocean
Galileo, perhaps more than any other single person, was responsible for the birth of modern science.Collection: Birth
I think the next century will be the century of complexity.Collection: Thinking
I do not believe in a personal God.Collection: Believe
Children in backseats cause accidents. Accidents in backseats cause children.Collection: Children
We see the universe the way it is because we exist.Collection: Way
It is tribute to how far we have come in theoretical physics that it now takes enormous machines and a great deal of money to perform experiments whose results we can not predict.Collection: Theoretical Physics
A million million million million (1 with twenty-four zeros after it) miles, the size of the observable universe.Collection: Twenties
The progress of the human race in understanding the universe has established a small corner of order in an increasingly disordered universe.Collection: Race
To boldly go where no one has gone beforeCollection: Courage
At times, I get very lonely because people are afraid to talk to me or don't wait for me to write a response. I'm shy and tongue-tied at times. I find it difficult to talk to people who I don't know.Collection: Lonely
"Sooner or later disasters such as an asteroid collision or a nuclear war could wipe us all out, But once we spread out into space and establish independent colonies, our future should be safe."Collection: War
Only a very few would allow creatures like us to exist. Thus our presence selects out from this vast array only those universes that are compatible with our existence. Although we are puny and insignificant on the scale of the cosmos, this makes us in a sense the lords of creation.Collection: Spring
The human race shouldn't have all its eggs in one basket, or on one planet. Let's hope we can avoid dropping the basket until we have spread the load.Collection: Race
I wouldnt be here today if it were not for the NHS, I have received a large amount of high-quality treatment without which I would not have survived.Collection: Nhs
Working with my father [Stephen Hawking ] is a great thrill - he has the amazing ability to hold enormous amounts of information in his head.Collection: Father
If you lined up all the cars in the world end to end, someone would try to pass them.Collection: Car
Observations indicate that the universe is expanding at an ever-increasing rate. It will expand forever, getting emptier and darker. Although the universe doesn’t have an end, it had a beginning in the Big Bang. One might ask what is before that but the answer is that there is nowhere before the Big Bang just as there is nowhere south of the South Pole.Collection: Forever
If human life were long enough to find the ultimate theory, everything would have been solved by previous generations. Nothing would be left to be discovered.Collection: Long
thus, in a sense, we are all doomed. even if we stay away from black holesCollection: Black
If it were only a few degrees, that would be serious, but we could adapt to it. But the danger is the warming process might be unstable and run away. We could end up like Venus, covered in clouds and with the surface temperature of 400 degrees. It could be too late if we wait until the bad effects of warming become obvious. We need action now to reduce emission of carbon dioxide.Collection: Running
The real challenge is to work out what aliens might actually be like.Collection: Real
But a machine that was powerful enough to accelerate particles to the grand unification energy would have to be as big as the Solar System - and would be unlikely to be funded in the present economic climate.Collection: Powerful
In fact, if one considers the possible constants and laws that could have emerged, the odds against a universe that produced life like ours are immense.Collection: Odds
Science could predict that the universe must have had a beginning.Collection: Universe
Eternity is a long time, especially towards the end.Collection: Funny
Many people do not like the idea that time has a beginning, probably because it smacks of divine intervention.Collection: Ideas
there is no prescribed route to follow to arrive at a new idea. You have to make the intuitive leap. But the difference is that once you've made the intuitive leap you have to justify it by filling in the intermediate steps. N my case, it often happens that I have an idea, but then I try to fill in the intermediate steps and find that they don't work, so I have to give it up.Collection: Ideas
The large-scale homogeneity of the universe makes it very difficult to believe that the structure of the universe is determined by anything so peripheral as some complicated molecular structure on a minor planet orbiting a very average star in the outer suburbs of a fairly typical galaxy.Collection: Stars
Scientists tend to risk theories they admireCollection: Risk
There is a real danger that computers will develop intelligence and take over.Collection: Real
The concern here is that financial services become a kind of tech-led Wild West.Collection: West
We are entering an increasingly dangerous period of our history. But I'm an optimist.Collection: Entering
One big contribution my father [Stephen Hawking] has made is to show that having a disability does not bar you from leading a full and eventful life.Collection: Father
