Quotes from Michio Kaku

The energy necessary to create a wormhole or to wrap time into nuts is incredible. It's not for us. It's maybe for our descendants who have mastered the energy of this technology. So if one day, somebody knocks on your door and claims to be your great great great great granddaughter, don't slam the door.

Once confined to fantasy and science fiction, time travel is now simply an engineering problem.

Time travel and teleportation will have to wait. It may take centuries to master these technology.

Originally, the burden of proof was on physicists to prove that time travel was possible. Now the burden of proof is on physicists to prove there must be a law forbidding time travel.

What we usually consider as impossible are simply engineering problems... there's no law of physics preventing them.

It's inevitable that we'll have some form of designer children, fueled not just by the science but by parents' hard-wired desire to give their children every advantage.

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

Years ago, I picked up figure skating. How hard could spins and jumps be, I thought? It's just applied Newtonian physics. After repeatedly falling on my rear end, I realized it was harder than I thought. But it had an upside. That is how I met my wife, who was ice dancing at the Rockefeller Center ice rink.

I predict that technology will enable people to transmit their neuronal, actual feelings over the Internet.

To become a theoretical physicist ... you need to have a passionate love affair with the universe.

I have nothing against investment banking, but it's like massaging money rather than creating money.

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.

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.

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.

When we're born, we want to know why the stars shine. We want to know why the sun rises.

My point is, no one can stop the Internet. No one can stop that march. It doesn't mean that it's going to be smooth, though.

Consciousness, there are about 20,000 papers on consciousness with no consensus. Nowhere in history have so many people devoted so much time to produce so little.

Your grades in school, your scores on the SAT, mean less for life success than your capacity to co-operate, your ability to regulate your emotions, your capacity to delay your gratification, and your capacity to focus your attention. Those skills are far more important—all the data indicate—for life success than your IQ or your grades.

Science, however, is never conducted as a popularity contest, but instead advances through testable, reproducible, and falsifiable theories.

The real bottleneck is software. Creating software can be done only the old-fashioned way. A human -sitting quietly in a chair with a pencil, paper and laptop- is going to have to write the codes... One can mass-produce hardware and increase it's power by piling on more and more chips, but you cannot mass-produce the brain.

There are two competing trends in the world today: one is to create a planetary civilization that is tolerant, scientific, and prosperous, but the other glorifies anarchy and ignorance that could rip the fabric of our society.

There is a saying among women scientists who attend highly specialized engineering universities, where the girl-to-guy ratio is decidedly in their favor: "The odds are good, but the goods are odd.")

We should try to leave the world a better place than when we entered it. As individuals, we can make a difference, whether it is to probe the secrets of Nature, to clean up the environment and work for peace and social justice, or to nurture the inquisitive, vibrant spirit of the young by being a mentor and a guide.

As Sir William Osler once said, "The philosophies of one age have become the absurdities of the next, and the foolishness of yesterday has become the wisdom of tomorrow.
