Michio Kaku Time Travel Quotes & Sayings

First, to create the violent distortions of space and time necessary to travel through a wormhole, one would need fabulous amounts of positive and negative matter, on the order of a huge star or a black hole. Matthew Visser, a physicist at Washington University, estimates that the amount of negative energy you would need to open up a 1-meter wormhole is comparable to the mass of Jupiter, except that it would need to be negative. He says, "You need about minus one Jupiter mass to do the job. Just manipulating a positive Jupiter mass of energy is already pretty freaky, well beyond our capabilities into the foreseeable future. — Michio Kaku

When you look at the calculation, it's amazing that every time you try to prove or disprove time travel, you've pushed Einstein's theory to the very limits where quantum effects must dominate. That's telling us that you really need a theory of everything to resolve this question. And the only candidate is string theory. — Michio Kaku

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

Physicists often quote from T. H. White's epic novel The Once and Future King , where a society of ants declares, 'Everything not forbidden is compulsory.' In other words, if there isn't a basic principle of physics forbidding time travel, then time travel is necessarily a physical possibility. (The reason for this is the uncertainty principle. Unless something is forbidden, quantum effects and fluctuations will eventually make it possible if we wait long enough. Thus, unless there is a law forbidding it, it will eventually occur.) — Michio Kaku

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. — Michio Kaku

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. — Michio Kaku

Because both quantum theory and Einstein's theory of gravity are united in ten-dimensional space, we expect that the question of time travel will be settled decisively by the hyperspace theory. As in the case of wormholes and dimensional windows, the final chapter will be written when we incorporate the full power of the hyperspace theory. — Michio Kaku

Twisting space-time into knots requires energy on a scale that will not be available within the next several centuries or even millenia-if ever. Even if all the nations of the world were to band together to build a machine that could probe hyperspace, they would ultimately fail. And, as Guth points out, the temperatures necessary to create a baby universe in the laboratory is 1,000 trillion trillion degrees, far in excess of anything available to us. In fact, that temperature is much greater than anything found in the interior of a star. So, although it is possible that Einstein's laws and the laws of quantum theory might allow for time travel, this is not within the capabilities of earthlings like us, who can barely escape the feeble gravitational field of our own planet. While we can marvel at the implications of wormhole research, realizing its potential is strictly reserved for advanced extraterrestrial civilizations. — Michio Kaku

Technologies that may be realized in centuries or millennium include: warp drive, traveling faster than the speed of light, parallel universes; are there other parallel dimensions and parallel realities? Time travel that we mentioned and going to the stars. — Michio Kaku

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. — 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. — Michio Kaku

If we can somehow control the probability of certain improbable events, then anything, including faster-than-light travel, and even time travel, is possible. Reaching the distant stars in seconds is highly unlikely, but when one can control quantum probabilities at will, then even the impossible may become commonplace. — Michio Kaku
