A Quote by Stephen Hawking

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.
With space travel, [it's] no different. You know, in 1990 I read the name Virgin Galactic Airways. Loved the name. And set out to try to find an engineer or rocket scientist in the world who could build a safe, reusable rocket that could take people to and from space and we could start a whole new era of commercial space travel.
Today, we know that time travel need not be confined to myths, science fiction, Hollywood movies, or even speculation by theoretical physicists. Time travel is possible. For example, an object traveling at high speeds ages more slowly than a stationary object. This means that if you were to travel into outer space and return, moving close to light speed, you could travel thousands of years into the Earth's future.
For years, my early work with Roger Penrose seemed to be a disaster for science. It showed that the universe must have begun with a singularity, if Einstein's general theory of relativity is correct. That appeared to indicate that science could not predict how the universe would begin.
Relativity was a highly technical new theory that gave new meanings to familiar concepts and even to the nature of the theory itself. The general public looked upon relativity as indicative of the seemingly incomprehensible modern era, educated scientists despaired of ever understanding what Einstein had done, and political ideologues used the new theory to exploit public fears and anxieties-all of which opened a rift between science and the broader culture that continues to expand today.
The real origin of science fiction lay in the seventeeth-century novels of exploration in fabulous lands. Therefore Jules Verne's story of travel to the moon is not science fiction because they go by rocket but because of where they go. It would be as much science fiction if they went by rubber band.
The 4D style, or cosmic comics and relativistic humor, is based on Einstein's theory of relativity which I came up with 20 years ago. 4D works use the idea of the fourth dimension, time, playing on such surrealistic and amazing subjects as motion relativity, space curvature and time dilation.
Einstein’s 1905 paper came out and suddenly changed people’s thinking about space-time. We’re again in the middle of something like that. When the dust settles, time—whatever it may be—could turn out to be even stranger and more illusory than even Einstein could imagine.
The supposed astronomical proofs of the theory [of relativity], as cited and claimed by Einstein, do not exist. He is a confusionist. The Einstein theory is a fallacy. The theory that ether does not exist, and that gravity is not a force but a property of space can only be described as a crazy vagary, a disgrace to our age.
The theory of relativity worked out by Mr. Einstein, which is in the domain of natural science, I believe can also be applied to the political field. Both democracy and human rights are relative concepts - and not absolute and general.
I heard that in relativity theory, space and time are the same thing. Einstein discovered this when he kept showing up three miles late for his meetings.
I became interested in this question of whether you can build wormholes for interstellar travel. I realized that if you had a wormhole, the theory of general relativity by itself would permit you to go backward in time.
Einstein was searching for String Theory. It not only reconciles General Relativity to Quantum Mechanics, but it reconciles Science and the Bible as well.
Einstein's theory of General Relativity has a mathematical structure very similar to Yang-Mills theory.
When forced to summarize the general theory of relativity in one sentence: Time and space and gravitation have no separate existence from matter.
I like the sci-fi channel. Just science in general. I came across a segment on time travel and how time travel is possible. We create a spaceship that's moving at almost the speed of light, we go in that spaceship in outer space, and we fly around for a year, when we get back to Earth, Earth would've aged 10 years.
Time is not a line but a dimension, like the dimensions of space. If you can bend space you can bend time also, and if you knew enough and could move faster than light you could travel backwards in time and exist in two places at once.
