born January 8, 1942; British physicist, scientist and
Because there is a law such as gravity, the universe can and will create itself from
I certainly don't have the answers to all life's problems. While physics and mathematics may
tell how the universe began, they are not much use in predicting human behaviour because
there are far too many equations to solve. I am no better than anyone else at understanding
what makes people tick, particularly women.
The downside of my celebrity is that I cannot go anywhere in the world without being
recognized. It is not enough for me to wear dark sunglasses and a wig. The wheelchair gives
Life in the universe will cease to be possible when the universe becomes cold, dark and
empty in about 15 billion years. But the real danger is that the human race will destroy itself
under a much shorter timescale. To have a chance of longterm survival we will have to
spread out into space.
So Einstein was wrong when he said, "God does not play dice." Consideration
of black holes
suggests, not only that God does play dice, but that he sometimes confuses us by throwing
them where they can't be seen.
To confine our attention to terrestrial matters would be to limit the human spirit.
I want to know why the universe exists, why there is something greater than nothing.
One can prove that God doesn't exist, but science makes God a necessary. The laws of
physics can explain the universe without the need for a creator.
I have noticed even people who claim everything is predestined, and that we can do nothing
to change it, look before they cross the road.
Can God make a stone that is so heavy that he cannot lift it? I don't think it is very useful to
speculate on what God might or might not be able to do. Rather, we should examine what he
actually does with the universe we live in. All our observations suggest that it operates
according to well-defined laws. These laws may have been ordained by God but it seems that
he does not intervene in the universe to break the laws, at least once he has set the universe
If aliens visit us, the outcome would be much as when Columbus landed in America, which
didn't turn out well for the Native Americans.
Women. They are a complete mystery.
Stephen Hawking, in response to the question: What do you think
most about during the
The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.
So long as the universe had a beginning, we could suppose it had a creator. But if the
universe is really completely self-contained, having no boundary or edge, it would have neither
beginning nor end: it would simply be. What place, then, for a creator?
I think we have a chance to survive long enough to colonize the solar system. However, there
is nowhere else in the solar system anything like as suitable as the earth. So it is not clear if
we would survive if the earth was made unfit for habitation. To ensure our longtime survival we
need to reach the stars; that will take much longer. Let's hope we can last till then.
Although I cannot move and I have to speak through a computer, in my mind I am free.
Even if there is only one possible unified theory, it is just a set of rules and equations. What is
it that breathes fire into the equations and makes a universe for them to describe? The usual
approach of science of constructing a mathematical model cannot answer the questions of
why there should be a universe for the model to describe. Why does the universe go to all the
bother of existing?
The human race is just a chemical scum on a moderate-sized planet, orbiting around a very
average star in the outer suburb of one among a hundred billion galaxies. We are so
insignificant that I can't believe the whole universe exists for our benefit. That would be like
saying that you would disappear if I closed my eyes.
It is all right to make mistakes; nothing is perfect because with perfection, we would not
One, remember to look up at the stars and not down at your feet. Two, never give up work.
Work gives you meaning and purpose and life is empty without it. Three, if you are lucky
enough to find love, remember it is there and don't throw it away.
Quiet people have the loudest minds.
I don't think the human race will survive the next thousand years, unless we spread into
space. There are too many accidents that can befall life on a single planet. But I'm an
optimist. We will reach out to the stars.
We are just an advanced breed of monkeys on a minor planet of a very average star. But we
can understand the Universe. That makes us something very special.
As we shall see, the concept of time has no meaning before the beginning of the universe.
This was first pointed out by St. Augustine. When asked: What did God do before he created
the universe? Augustine didn't reply: He was preparing Hell for people who asked such
questions. Instead, he said that time was a property of the universe that God created, and
that time did not exist before the beginning of the universe.
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.
Intelligence is the ability to adapt to change.
Science is beautiful when it makes simple explanations of phenomena or connections between
