A Quote by Margaret Atwood
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.

Time is said to have only one dimension, and space to have three dimensions. ... The mathematical quaternion partakes of both these elements; in technical language it may be said to be 'time plus space', or 'space plus time': and in this sense it has, or at least involves a reference to, four dimensions. And how the One of Time, of Space the Three, Might in the Chain of Symbols girdled be.
Time is not a line but a dimension, like the dimensions of space.
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.
In the context of general relativity, space almost is a substance. It can bend and twist and stretch, and probably the best way to think about space is to just kind of imagine a big piece of rubber that you can pull and twist and bend.
The obvious thing to me was, let's take freely floating masses in space and measure the time it takes light to travel between them. The presence of a gravitational wave would change that time. Using the time difference, one could measure the amplitude of the wave.
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.
What differentiates time from space is that time does have a direction. In that sense it is different from space. I think that's certainly true that whereas spatial dimensions don't have direction or an arrow, time does. It runs from past to future. But I see that arrow of time as rooted in a deeper metaphysical reality, namely the reality of temporal becoming - of things coming to be and passing away. That is why time has this arrow. But it's not sufficient to simply say that time and space are distinct because time has a direction. The question will be: why does it have a direction?
Books must be treated with respect, we feel that in our bones, because words have power. Bring enough words together they can bend space and time.
Space and time are real for the man who is yet imperfect, and space is divided for him into dimensions; time, into past, present, and future.
Dancing is surely the most basic and relevant of all forms of expression. Nothing else can so effectively give outward form to an inner experience. Poetry and music exist in time. Painting and architecture are a part of space. But only the dance lives at once in both space and time. In it the creator and the thing created, the artist and the expression, are one. Each participates completely in the other. There could be no better metaphor for an understanding of the mechanics of the cosmos.
Did Belikov bend the rules of time and space to get here so fast? He can do that, right?
The dance is the mother of the arts. Music and poetry exist in time; painting and architecture in space. But the dance lives at once in time and space.
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.
Any time you do something, you make decisions about time and space. I wanted those decisions to be out of my hands. I could be dragged, carried along by another person, I could be a receiver. I could be the agent of the overall scheme, but I didn't want to be the agent of the particular action. I could make the ultimate decision that my space is going to change now, but I don't know where it's going to go.
What we end up calling history is a kind of knife, slicing down through time. A few people are hard enough to bend its edge. But most won't even stand close to the blade. I'm one of those. We don't bend anything.
In space-time everything which for each of us constitutes the past, the present and the future is given en bloc...Each observer, as his time passes, discovers, so to speak, new slices of space-time which appear to him as successive aspects of the material world, though in reality the ensemble of events constituting space-time exist prior to his knowledge of them.
