Quotes from Stephen Hawking

Remember to look up at the stars and not down at your feet. Try to make sense of what you see, wonder about what makes the universe exist. Be curious. However difficult life may seem, there is always something you can do and succeed at. It matters that you don't just give up.

There is no time to wait for Darwinian evolution to make us more intelligent and better natured. But we are now entering a new phase of what might be called self-designed evolution, in which we will be able to change and improve our DNA.

There is a black hole with a mass of about four million times that of the Sun at the centre of our Milky Way galaxy.

we can really be sure of is that even if the universe is going to recollapse, it won't do so for at least another ten thousand million years, since it has already been expanding for at least that long. This should not unduly worry us: by that time, unless we have colonized beyond the Solar System, mankind will long since have died out, extinguished along with our sun!

You can call the universe many things – awesome, beautiful, violent – but one thing you can't call it is cramped.

For every event in space-time we may construct a light cone (the set of all possible paths of light in space-time emitted at that event), and since the speed of light is the same at every event and in every direction, all the light cones will be identical and will all point in the same direction.

Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it.

Solo somos una raza avanzada de monos....pero podemos comprender el universo

Aprovechemos cada momento. Actuemos ahora mismo.

We spend a great deal of time studying history, which, let's face it, is mostly the history of stupidity. So

the universe is governed by a set of rational laws that we can discover and understand.

hope that going forward, even when I am no longer here, people with power can show creativity, courage and leadership. Let them rise to the challenge of the sustainable development goals, and act, not out of self-interest, but out of common interest. I

Después de que mis expectativas se hubieran reducido a cero, cada nuevo dia se convirtió en una propina y empecé a apreciar todo lo que tenia.

The role played by time at the beginning of the universe is, I believe, the final key to removing the need for a grand designer and revealing how the universe created itself.

It is a waste of time to be angry about my disability. One has to get on with life and I haven't done badly. People won't have time for you if you are always angry or complaining. - Stephen Hawking

We have this one life to appreciate the grand design of the universe, and for that I am extremely grateful.

however, not very accurate, and so his value for the speed of light was 140,000 miles per second, compared to the modern value of 186,000 miles per second. Nevertheless, Roemer's achievement, in not only proving that light travels at a finite speed, but also in measuring that speed, was remarkable—coming as it did eleven years before Newton's publication of Principia Mathematica.

We live in bewildering world

You can't afford to be disabled in spirit as well as physically. People won't have time for you.

In order to understand the origin of the universe, one therefore has to incorporate the Uncertainty Principle into Einstein's general theory of relativity. This has been the great challenge in theoretical physics for at least the last thirty years. We haven't solved it yet, but we have made a lot of progress.

This apparent loss of information, known as the information paradox, has troubled scientists for the last forty years, and still remains one of the biggest unsolved problems in theoretical physics.

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.
