Time travel used to be thought of as just science fiction, but Einstein’s general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out.

I read ‚The High Frontier‘ in high school. I read it multiple times, and I was already primed. As soon as I read it, it made sense to me. It seemed very clear that planetary surfaces were not the right place for an expanding civilization inside our solar system.

Science is global. Einstein’s equation, E=mc2, has to reach everywhere. Science is a beautiful gift to humanity, we should not distort it. Science does not differentiate between multiple races.

I grew up in a rural area called Vega Baja and I’m the first of so many talented people in this area to make it out. I take great pride to represent where I come from and I am able to show my fans, and everyone who listens and watches me, that anything is possible.

I think it would be interesting if old people got anti-Alzheimer’s disease where they slowly began to recover other people’s lost memories.

Read no history: nothing but biography, for that is life without theory.

It cannot be said often enough that science fiction as a genre is incredibly educational – and I’m speaking the written science fiction, not ‚Star Trek.‘ Science fiction writers tend to fill their books if they’re clever with little bits of interesting stuff and real stuff.

I was a very keen reader of science fiction.

If people take anything from my music, it should be motivation to know that anything is possible as long as you keep working at it and don’t back down.

I never accepted Communist dogma or theory.

When I was making ‚Star Wars,‘ I wasn’t restrained by any kind of science. I simply said, ‚I’m going to create a world that’s fun and interesting, makes sense, and seems to have a reality to it.‘

I have a theory that the truth is never told during the nine-to-five hours.

It has yet to be proven that intelligence has any survival value.

There are certain people who elicit a really passionate response. It’s crazy. That’s my Alexander Wang theory.

A professor must have a theory as a dog must have fleas.

The experience of God, or in any case the possibility of experiencing God, is innate.

Apparently there is nothing that cannot happen today.

I know the blessing of having a dad who played 16 years in the league. That experience, and seeing him as an example, let me know that it’s possible. It’s not easy, but it’s possible.

I got into science fiction by being interested in astronomy first.

We’ve gotta become the Martians. I’m a Martian – I tell you to become Martians. And we’ve gotta go to Mars and civilize Mars and build a whole civilization on Mars and then move out, 300 years from now into the universe. And when we do that, we have a chance of living forever.

Science fiction is any idea that occurs in the head and doesn’t exist yet, but soon will, and will change everything for everybody, and nothing will ever be the same again. As soon as you have an idea that changes some small part of the world you are writing science fiction. It is always the art of the possible, never the impossible.

Science fiction writers foresee the inevitable, and although problems and catastrophes may be inevitable, solutions are not.

Democracy is the theory that the common people know what they want, and deserve to get it good and hard.

I dwell in possibility.

The most watched programme on the BBC, after the news, is probably ‚Doctor Who.‘ What has happened is that science fiction has been subsumed into modern literature. There are grandparents out there who speak Klingon, who are quite capable of holding down a job. No one would think twice now about a parallel universe.

If an elderly but distinguished scientist says that something is possible, he is almost certainly right; but if he says that it is impossible, he is very probably wrong.

Today, all physicists know from studying Einstein and Bohr that sometimes an idea which looks completely paradoxical at first, if analyzed to completion in all detail and in experimental situations, may, in fact, not be paradoxical.

It was Einstein’s dream to discover the grand design of the universe, a single theory that explains everything. However, physicists in Einstein’s day hadn’t made enough progress in understanding the forces of nature for that to be a realistic goal.

He who loves practice without theory is like the sailor who boards ship without a rudder and compass and never knows where he may cast.

I was never top of the class at school, but my classmates must have seen potential in me, because my nickname was ‚Einstein.‘

The theory seems to be that as long as a man is a failure he is one of God’s children, but that as soon as he succeeds he is taken over by the Devil.

I hope to build a reputation as a science-fiction writer. That’s the pitch. We’ll see.

If you look at ‚Blade Runner,‘ it’s been cut sixteen ways from Sunday, and there are all kinds of different versions of it.

It’s perfectly obvious that there is some genetic factor that distinguishes humans from other animals and that it is language-specific. The theory of that genetic component, whatever it turns out to be, is what is called universal grammar.

I put instant coffee in a microwave oven and almost went back in time.

Even if it turns out that time travel is impossible, it is important that we understand why it is impossible.

Obviously I faced the possibility of not returning when first I considered going. Once faced and settled there really wasn’t any good reason to refer to it.

I grew up reading science fiction.

Today I continue with my science-fiction reading habit and find it very mind-expanding. Always makes me think.

If it looks like a duck, and quacks like a duck, we have at least to consider the possibility that we have a small aquatic bird of the family anatidae on our hands.

Creationists make it sound as though a ‚theory‘ is something you dreamt up after being drunk all night.

Because a thing seems difficult for you, do not think it impossible for anyone to accomplish.

I have a theory about the human mind. A brain is a lot like a computer. It will only take so many facts, and then it will go on overload and blow up.

There is no body of theory or significant body of relevant information, beyond the comprehension of the layman, which makes policy immune from criticism.

If I pick up a book with spaceships on the cover, I want spaceships. If I see one with dragons, I want there to be dragons inside the book. Proper labeling. Ethical labeling. I don’t want to open up my cornflakes and find that they’re full of pebbles… You need to respect the reader enough not to call it something it isn’t.

When I die, I’m gonna leave my body to science fiction.

Scientific views end in awe and mystery, lost at the edge in uncertainty, but they appear to be so deep and so impressive that the theory that it is all arranged as a stage for God to watch man’s struggle for good and evil seems inadequate.

The theory of Communism may be summed up in one sentence: Abolish all private property.

The dominant theory coming out of Hollywood is that peoples‘ attention spans are getting shorter and shorter and they need more stimulation.

The moment a person forms a theory, his imagination sees in every object only the traits which favor that theory.

Experience without theory is blind, but theory without experience is mere intellectual play.

Thought and theory must precede all salutary action; yet action is nobler in itself than either thought or theory.

I’ve only written one science-fiction book: ‚Fahrenheit 451.‘ That book is a book based on real facts and my hatred of people who destroy books.

When I die, I’m leaving my body to science fiction.

I cannot discover that anyone knows enough to say definitely what is and what is not possible.

Politicians should read science fiction, not westerns and detective stories.

If the experiments which I urge be defective, it cannot be difficult to show the defects; but if valid, then by proving the theory, they must render all objections invalid.

Einstein’s gravitational theory, which is said to be the greatest single achievement of theoretical physics, resulted in beautiful relations connecting gravitational phenomena with the geometry of space; this was an exciting idea.

When I write about a 15-year old, I jump, I return to the days when I was that age. It’s like a time machine. I can remember everything. I can feel the wind. I can smell the air. Very actually. Very vividly.

The situation in the sciences is this: A concept or an idea which cannot be measured or cannot be referred directly to experiment may or may not be useful. It need not exist in a theory.

It doesn’t matter how beautiful your theory is, it doesn’t matter how smart you are. If it doesn’t agree with experiment, it’s wrong.
