Michio Kaku Quotes

Wormholes are a gravitational phenomena. Or imaginary gravitational phenomena, as the case may be.

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.

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.

Wormholes don't exist because the only way they would exist is if they were seeded with exotic material created by an intelligence far beyond our own. Something would have to make one.

I like science fiction, I like fantasy, I like time travel, so I had this idea: What if you had a phone that could call into the past?

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.

If you have a wormhole, then you can turn them into time machines for going backward in time.

… theoretical physics is actual philosophy. It has revolutionized fundamental concepts, e.g., about space and time (relativity), about causality (quantum theory), and about substance and matter (atomistics), and it has taught us new methods of thinking (complementarity) which are applicable far beyond physics.

If we do get a quantum theory of spacetime, it should answer some of the deepest philosophical questions that we have, like what happened before the big bang?

Time travel is a fantasy we all have. The 'Back to the Future' series really exploits that wish.

Wormholes - if you don't have something threading through them to hold them open, the walls will basically collapse so fast that nothing can go through them.

What I do for living, working on something called string theory which we think may answer the fundamental question: Are there other universes? Can you go through a black hole? Can you warp the fabric of space and time and meet your mother before you were born? These are all questions that in principle string theory should be able to answer.

Science fiction is the branch of literature that deals with the effects of change on people in the real world as it can be projected into the past, the future, or to distant places. It often concerns itself with scientific or technological change, and it usually involves matters whose importance is greater than the individual or the community; often civilization or the race itself is in danger.

Life is full of little surprises. Time travel is full of big ones.

Like anyone nostalgic for a time he didn't live through, I chose to weed out the little inconveniences: polio, say, or the thought of eating stewed squirrel. The world was simply grander back then, somehow more civilized, and nicer to look at.

We could tell them [alien civilization] things that we have discovered in the realm of mathematical physics, but there is stuff that I would like to know. There are some famous problems like how to bring gravitation and quantum physics together, the long-sought-after theory of quantum gravity. But it may be hard to understand the answer that comes back.

All this money can't buy me a time machine.

If I have the chance to time travel, might as well go all out.

I have tried to read philosophers of all ages and have found many illuminating ideas but no steady progress toward deeper knowledge and understanding. Science, however, gives me the feeling of steady progress: I am convinced that theoretical physics is actual philosophy. It has revolutionized fundamental concepts, e.g., about space and time (relativity), about causality (quantum theory), and about substance and matter (atomistics), and it has taught us new methods of thinking (complementarity) which are applicable far beyond physics.

Time machine... wouldn't you like to travel through time? I would. I'd go back... mess with people. You know what I would do? I would go back to when my mom and dad were having sex, to have me. Ya'know, come in, spank my dad on the ass I'm your son from the future! Ahaha!

Still, looking through the old volumes was soothing, because thinking of the past made the present seem a little less real.

When we gaze at a star in the Milky Way which is 50,000 light-years away from our sun, we are looking back 50,000 years in time." "The idea is much too big for my little head." "The only way we can look out into space, then, is to look back in time. We can never know what the universe is like now. We only know what it was like then. When we look up at a star that is thousands of light-years away, we are really traveling thousands of years back in the history of space.

[T]he atoms or elementary particles themselves are not real; they form a world of potentialities or possibilities rather than one of things or facts.

There's a bridge to tomorrow, There's a bridge to the past.

If there is a next life, I hope it's in the past; I don't think the future will be any more handleable. I think it's a little harsh how the END button is red.
