A Quote by Antonino Zichichi
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 the first time American astronauts on the International Space Station ate vegetables grown in space. In other words, even space is getting more rain than California.
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.
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.
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.
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.
I also require much time to ponder over the matters themselves, and particularly the principles of mechanics (as the very words: force, time, space, motion indicate) can occupy one severely enough; likewise, in mathematics, the meaning of imaginary quantities, of the infinitesimally small and infinitely large and similar matters.
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.
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.
There is nothing mysterious about space-time. Every speck of matter, every idea, is a space-time event. We cannot experience anything or conceive of anything that exists outside of space-time. Just as experience precedes all awareness and creative expression, the visual language of our photographs should ever more strongly express the fourth dimensional structure of the real world.
I actually had four space flights altogether, three times on shuttles. My second flight was really unique for me because I was going back into space, first of all. The first one was like an appetizer at a nice dinner. You know, you want to go up and you want more. So, the second time I got into space, it was neat because I got to actually do two space walks.
We name one thing and then another. That’s how time enters poetry. Space, on the other hand, comes into being through the attention we pay to each word. The more intense our attention, the more space, and there’s a lot of space inside words.
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?
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.
The influence of the senses have in men overpowered the thought to the degree that the walls of time and space have come to look solid, real and insurmountable. .. Yet time and space are but inverse measures of the power of the mind. Man is capable of abolishing them both.
Today's particle physics describe light as a crumple in space, and we may have deformed space in such a way that they noticed something peculiar - and they had the ability to investigate it.
... If we consider the difference between William Henry Jackson packing in his camera by mule, and the person stepping for a moment from his car to take a picture with his Instamatic, it becomes clear how some of our space has vanished; if the time it takes to cross space is a way by which we define it, then to arrive at a view of space 'in no time' is to have denied its reality.
