Quotes from Stephen Hawking

Intelligence is the ability to adapt to change. Stephen Hawking

My advice to any heartbroken young girl is to pay close attention to the study of theoretical physics. Because one day there may well be proof of multiple universes. It would not be beyond the realms of possibility that somewhere outside of our own universe lies another different universe. And in that universe, Zayn is still in One Direction.

Scientists tend to risk theories they admire

only in the few universes that are like ours would intelligent beings develop and ask the question: "Why is the universe the way we see it?" The answer is then simple: If it had been any different, we would not be here!

Traditionally these are questions for philosophy, but philosophy is dead. Philosophy has not kept up with modern developments in science, particularly physics. Scientists have become the bearers of the torch of discovery in our quest for knowledge.

In this way, Edwin Hubble worked out the distances to nine different galaxies. We now know that our galaxy is only one of some hundred thousand million that can be seen using modern telescopes, each galaxy itself containing some hundred thousand million stars.

When a book was published entitled 100 Authors Against Einstein, he retorted, "If I were wrong, then one would have been enough!

We create history by our observation, rather than history creating us.

Or in other words, why does disorder increase in the same direction of time as that in which the universe expands?

The people who actually make the advances in theoretical physics don't think in these categories that the philosophers and the historians of science subsequently invent for them

As a father, I would try to instill the importance of asking questions, always.

there are lots of things you want to do before your life is over.

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.

As often happens in science, discoveries are made in the pursuit of an elusive (and sometimes nonexistent) goal.

In an infinite universe, every point can be regarded as the center, because every point has an infinite number of stars on each side of it. The

The computer in your cell phone today is a million times cheaper and a thousand times more powerful and about a hundred thousand time smaller than the one computer at MIT in 1965.

There should be no boundaries to human endeavor. (...) However bad life may seem (...) While there's life, there is hope.

This means it will take about a thousand million million million million years for the earth to run into the sun, so there's no immediate cause for worry!

why are we here? where do we come from? traditionally,these are questions for philosophy,but philosophy is dead

The message of this lecture is that black holes ain't as black as they are painted. They are not the eternal prisons they were once though…things can get out of a black hole both on the outside and possibly to another universe. So if you feel you are in a black hole, don't give up – there's a way out.

I'm the archetype of a disabled genius, or should I say a physically challenged genius, to be politically correct. At least I'm obviously physically challenged. Whether I'm a genius is more open to doubt.

If you understand how the universe operates, you control it, in a way.

It is generally recognized that women are better than men at languages, personal relations and multitasking, but less good at map-reading and spatial awareness. It is therefore not unreasonable to suppose that women might be less good at mathematics and physics. It is not politically correct to say such things....But it cannot be denied that there are differences between men and women. Of course, these are differences between the averages only. There are wide variations about the mean.

Both observer and observed are parts of the world that has an objective existence, and any distinction between them has no meaningful significance. In other words, if you see a herd of zebras fighting for a spot in the parking garage, it is because there really is a herd of zebras fighting for a spot in the parking garage.
