Quotes by Michio Kaku

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.

I like to engage the public because when I was in high school, I had all these questions about anti-matter, higher dimensions and time travel. Every time I went to the library, every time I asked people these questions, I would get some strange looks. Nobody could answer any of these questions.

Time travel and teleportation will have to wait. It may take centuries to master these technology. But within the coming decades, we will understand dark matter, perhaps test string theory, find planets which can harbor life, and maybe have Brain 2.0, i.e. our consciousness on a disk which will survive even after we die.

In the 1950s, we had all these B-grade science-fiction movies. The point was to scare the public and get them to buy popcorn. No attempt was made to create movies that were somewhat inherent to the truth.

So often, science fiction helps to get young people interested in science. Thats why I dont mind talking about science fiction. It has a real role to play: to seize the imagination.

One day I went up to my mom and I said, Mom, can I have permission to build a 2.3-million electron-volt atom smasher - a betatron - in the garage? And my mom stared at me, and she said, Sure. Why not? And dont forget to take out the garbage.

Democracies are slow to anger and hesitant to go to war: Voters dont want to sacrifice their children for the glory of a selfish king.

In the future, I can imagine that we will genetically modify ourselves using the genes that have doubled our life span since we were chimpanzees.

“Astronomers suspect that the Oort Cloud could extend as far as three light-years from our solar system. That is more than halfway to the nearest stars, the Centauri triple star system, which is slightly more than four light-years from Earth. If we assume that the Centauri star system is also surrounded by a sphere of comets, then there might be a continuous trail of comets connecting it to Earth. It may be possible to establish a series of refueling stations, outposts, and relay locations on a grand interstellar highway. Instead of leaping to the next star in one jump, we might cultivate the more modest goal of comet hopping to the Centauri system. This thoroughfare could become a cosmic Route 66.”

“By 2100, our destiny is to become like the gods we once worshipped and feared. But our tools will not be magic wands and potions but the science of computers, nanotechnology, artificial intelligence, biotechnology, and most of all, the quantum theory.”
