A Quote by Stephen Hawking
Because imaginary time behaves like another direction in space, histories in imaginary time can be closed surfaces, like the surface of the Earth, with no [existential] beginning or end.

Place, time, life, death, earth, heaven are divisions and distinctions we make, like the imaginary lines we trace upon the surface of the globe.
In the 1920s the young English physicist Paul Dirac began trying to understand and describe the space-time evolution of the electron, the first elementary particle discovered by J.J. Thomson in 1897. Dirac was puzzled by an unprecedented property of space-time, discovered by Lorentz in his studies of electromagnetic forces, whereby if space was real, time had to be imaginary, and vice versa. In other words, space and time had to be a ‘complex’ mixture of two quantities, one real and the other imaginary.
For any artistic person who creates imaginary people, the art is like inhabiting the life and mind of a seven-year-old child with imaginary friends and imaginary events and imaginary grace and imaginary tragedy. Within that alternate universe, the characters do have quite a bit of free will. I know it's happening in my mind and my mind alone, but they seem to have their own ability to shape their destinies. So I'm not shooting for anything. If the characters are vulnerable it's simply because they're very human.
Boundary, n. In political geography, an imaginary line between two nations, separating the imaginary rights of one from the imaginary rights of another.
I was at a stage in my life where I felt sort of comfortable being a dislocated person emotionally, feeling in some ways like a man without any particular country. I had come to a nice space with the imaginary Cuba or the imaginary America that I thought existed.
I like how time goes on set. It's almost like time on an airplane or something where people are together. It's a different, very trippy kind of time, I find, because you're together in imaginary time where you're out of time. You're called upon to be present and honor what can happen in the moment. And the whole day can go like that. The whole day can be a kind of meditation.
We actors do this to pretend, to go into imaginary circumstances, so when the imaginary circumstance is of a different time, that just compounds the joy of doing what we do.
I started to make a joke that I had an imaginary friend underneath the let-out couch named Binky. I would never talk to him; I would only use him as entertainment for other people. I knew they thought that children had imaginary friends, so I was like, "I don't really believe in imaginary friends, but I want to feel like I do." I used to make a joke, "My imaginary friend Binky says this," because I knew it would get a laugh out of them.
The world consists of imaginary people, claiming imaginary virtues and suffering from imaginary happiness.
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?
I'm creating an imaginary — it's always imaginary — world in which I would like to live.
Gravity is so strong that space is bent round onto itself, making it rather like the surface of the earth. If one keeps traveling in a certain direction on the surface of the earth, one never comes up against an impassable barrier or falls over the edge, but eventually comes back to where one started.
Philosophers make imaginary laws for imaginary commonwealths, and their discourses are as the stars, which give little light because they are so high.
Gods, religions and national boundaries are absolutely imaginary. They don't tend to exist. As soon as you pull back half a mile and look down at the Earth there are no national boundaries. There aren't even national boundaries when you get down and walk around. They're just imaginary lines we draw on maps. I just get fascinated by people who assume that things that are imaginary have no relevance to their lives.
Pure, existential space was regularly winking at me, each time in a more impressive manner, and this sensation of total freedom attracted me so powerfully that I painted some monochrome surfaces just to 'see,' to 'see' with my own eyes what existential sensibility granted me: absolute freedom!
Time can behave like another direction in space under extreme conditions.
