There is so much noise on the Internet, with would-be prophets daily haranguing their audience and megalomaniacs trying to push bizarre ideas, that eventually people will cherish a new commodity: wisdom.

The human brain has 100 billion neurons, each neuron connected to 10 thousand other neurons. Sitting on your shoulders is the most complicated object in the known universe.

I think the 'Terminator' idea is a reasonable one - that is that one day the Internet becomes self-aware and simply says that humans are in the way. After all, if you meet an ant hill and you're making a 10-lane super highway, you just pave over the ants. It's not that you don't like the ants, it's not that you hate ants; they are just in the way.

In Einstein's equation, time is a river. It speeds up, meanders, and slows down. The new wrinkle is that it can have whirlpools and fork into two rivers. So, if the river of time can be bent into a pretzel, create whirlpools and fork into two rivers, then time travel cannot be ruled out.

I am a futurist, projecting trends in science into the next decades and century, but ironically my two daughters - one is a neuroscientist and the other is a pastry chef - tell me that my taste in music is positively prehistoric.

You see, I'm also a futurist. I dream about the world 50, 100, maybe even 1,000 years in the future. But I also realize I'm probably not going to see it. However, I wouldn't mind having at least a copy of myself see the future, maybe 50, 100, 1,000 years into the future. It would be a fantastic ride.

We need less memorization - I never memorized the periodic table of the elements - I've never used it, and I'm a physicist! I can look it up.

Physics is often stranger than science fiction, and I think science fiction takes its cues from physics: higher dimensions, wormholes, the warping of space and time, stuff like that.

Most Jupiter-sized planets orbit the mother star in a highly elliptical orbit. This means they will often cross the orbit of any Earth-like planet and fling it into outer space, making life impossible. But our Jupiter travels in a near-perfect circular orbit, preventing a collision with any Earth-like planet, making life possible.

Until computers and robots make quantum advances, they basically remain adding machines: capable only of doing things in which all the variables are controlled and predictable.

Democracies are slow to anger and hesitant to go to war: Voters don't want to sacrifice their children for the glory of a selfish king.

I have concluded that we are in a world made by rules created by an intelligence.

String theory is based on the simple idea that all the four forces of the universe: gravity, the electromagnetic force and the two nuclear forces, can be viewed, as music.

Scientists willing to risk their reputations on higher dimensions soon found themselves ridiculed by the scientific community. Higher-dimensional space became the last refuge for mystics, cranks, and charlatans.

In my mind, there is no question that they're out there. My Career is well established. My texts books are required reading in all the major capitals on planet earth. If you want to become a physist to learn about the unified feild therory-you read my books. Therefore, I'm in a position to say: Yes- Most likely they're out their, perhaps even visited, perhaps on our moon.

What do oil company executives, vampires and NASA bureaucrats all have in common? They fear solar energy.

To understand the difficulty of predicting the next 100 years, we have to appreciate the difficulty that the people of 1900 had in predicting the world of 2000.

In some sense, gravity does not exist; what moves the planets and the stars is the distortion of space and time.

Physicists are made of atoms. A physicist is an attempt by an atom to understand itself.

We can summarize electricity, magnetism and gravity into equations one inch long, and that's the power of field theory. And so I said to myself: I will create a field theory of strings. And when I did it one day, it was incredible, realizing that on a sheet of paper I can write down an equation which summarized almost all physical knowledge.

The universe is a symphony of strings, and the mind of God that Einstein eloquently wrote about for thirty years would be cosmic music resonating through eleven-dimensional hyper space.
