A Quote by Stephen Hawking
Before 1915, space and time were thought of as a fixed arena in which events took place, but which was not affected by what happened in it. Space and time are now dynamic quantities... space and time not only affect but are also affected by everything that happens in the universe.

But as Van casually directed the searchlight of backthought into that maze of the past where the mirror-lined narrow paths not only took different turns, but used different levels (as a mule-drawn cart passes under the arch of a viaduct along which a motor skims by), he found himself tackling, in still vague and idle fashion, the science that was to obsess his mature years - problems of space and time, space versus time, time-twisted space, space as time, time as space - and space breaking away from time, in the final tragic triumph of human cogitation: I am because I die.
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.
Space expands or contracts in the tensions and functions through which it exists. Space is not a static, inert thing. Space is alive; space is dynamic; space is imbued with movement expressed by forces and counterforces; space vibrates and resounds with color, light and form in the rhythm of life.
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.
If space is a fabric, then of course fabrics can have ripples, which we have now seen directly. But fabrics can also rip. Then the question is what happens when the fabric of space and time is ripped by a black hole?
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.
There is, therefore, no difficulty in answering such questions as these. What cause was there why the Universe was placed in such a part of Space? and, Why was the Universe created at such a Time? for, if there be no Space beyond the Universe, it was impossible that it should be created in another place; and if there was no Time before, it was impossible it should be created at another time.
The whole universe is one. There is only one Self in the universe, only One Existence, and that One Existence, when it passes through the forms of time, space, causation, is called by different names, buddhi, fine matter, gross matter, all mental and physical forms. Everything in the universe is that One, appearing in various forms. When a little part of it comes, as it were, into this network of time, space and causation, it takes forms. Take off the network, and it is all one.
What really made me think about space and begin to think about ways to use it was Einstein's statement that there are no fixed points in space. Everything in the universe is moving all the time.
Who what am I? My answer: I am the sum total of everything that went before me, of all I have been seen done, of everything done-to-me. I am everyone everything whose being-in-the-world affected was affected by mine. I am anything that happens after I’ve gone which would not have happened if I had not come. Nor am I particularly exceptional in this matter; each "I", every one of the now-six-hundred-million-plus of us, contains a similar multitude. I repeat for the last time: to understand me, you’ll have to swallow the world.
I sometimes ask myself how it came about that I was the one to develop the theory of relativity. The reason, I think, is that a normal adult never stops to think about problems of space and time. These are things which he has thought about as a child. Bu t my intellectual development was retarded,as a result of which I began to wonder about space and time only when I had already grown up.
Space, time, mass, and energy originate from Chaos, have their being in Chaos, and through the agency of the aether are moved by Chaos into the multiple forms of existence. Some of the various densities of the aether have only a partial or probablistic differentiation into existence, and are somewhat indeterminate in space and time. In the same way that mass exists as a curvature in space-time, extending with a gradually diminishing force to infinity that we recognize as gravity, so do all events, particularly events involving the human mind, send ripples through all creation.
There is something going on in time and space, and beyond time and space, which, whether we like it or not, spells duty.
We confuse ourselves with space-time events, when in fact we are the ones who generate these space-time events.
Musing takes place in a kind of meadowlands of the imagination, a part of the imagination that has not yet been plowed, developed, or put to any immediately practical use…time spent there is not work time, yet without that time the mind becomes sterile, dull, domesticated. The fight for free space — for wilderness and public space — must be accompanied by a fight for free time to spend wandering in that space.
If our friendship depends on things like space and time, then when we finally overcome space and time, we've destroyed our own brotherhood! But overcome space, and all we have left is Here. Overcome time, and all we have left is Now. And in the middle of Here and Now, don't you think that we might see each other once or twice?
