Times are legion: a different one for every point in space. There is not one single time; there is a vast multitude of them. The time indicated by a particular clock measuring a particular phenomenon is called 'proper time' in physics. Every clock has its proper time. Every phenomenon that occurs has its proper time, its own rhythm.

Space is a spin network whose nodes represent its elementary grains, and whose links describe their proximity relations. Spacetime

the particles are quanta of quantum fields; light is formed by quanta of a field; space is nothing more than a field, which is also made of quanta; and time emerges from the processes of this same field. In other words, the world is made entirely from quantum fields (

This is how time is depicted in Einstein's general theory of relativity. His equations do not have a single "time"; they have innumerable times.

Se il mondo è un un pullulare di effimeri quanti di spazio e di materia, un immenso gioco a incastri di spazio e particelle elementari, noi cosa siamo? [...] Nel grande quadro della scienza contemporanea ci sono molte cose che non capiamo, e una di quelle che capiamo meno siamo noi stessi

Time has lost its first aspect or layer: its unity. It has a different rhythm in every different place and passes here differently from there.

It's a moment of enlightenment. A momentous simplification of the world: space is no longer something distinct from matter—it is one of the "material" components of the world. An entity that undulates, flexes, curves, twists.

C'è così tanto spazio lassù, è puerile pensare che in quest'angolo periferico di una galassia delle più banali ci sia qualcosa di speciale. La vita sulla Terra non è che un assaggio di cosa può succedere nell'universo.

the particles are quanta of quantum fields; light is formed by quanta of a field; space is nothing more than a field, which is also made of quanta;

Where are these quanta of space? Nowhere. They are not in space because they are themselves the space. Space is created by the linking of these individual quanta of gravity. Once again, the world seems to be less about objects than about interactive relationships.

What happens between one interaction and the next is not mentioned in the theory. It does not exist.

A handful of types of elementary particles, which vibrate and fluctuate constantly between existence and nonexistence and swarm in space, even when it seems that there is nothing there, combine together to infinity like the letters of a cosmic alphabet to tell the immense history of galaxies; of the innumerable stars; of sunlight; of mountains, woods, and fields of grain; of the smiling faces of the young at parties; and of the night sky studded with stars.

Time and space are real phenomena. But they are in no way absolute; they are not at all independent from what happens; they are not as different from the other substances of the world, as Newton had imagined them to be. We can think of a great Newtonian canvas on which the story of the world is drawn. But this canvas is made of the same stuff that everything else in the world is made of, the same substance that constitutes stone, light, and air: it is made of fields.

the world is made entirely from quantum fields. These fields do not live *in* spacetime; they live, so to speak, one on top of the other: fields on fields. The space and time that we perceiv in large scale are our blurred and approximage image of one of these quantum fields: the gravitational field (193).

Time sits at the center of the tangle of problems raised by the intersection of gravity, quantum mechanics, and thermodynamics.

Democritus himself, who had placed empty space at the basis of his world where atoms course, certainly wasn't crystal clear on the issue: he wrote that empty space is something "between being and non-being":

And it's here that Einstein's extraordinary stroke of genius occurs, one of the greatest flights in the history of human thinking: what if the gravitational field turned out actually to be Newton's mysterious space? What if Newton's space was nothing more than the gravitational field? This extremely simple, beautiful, brilliant idea is the theory of general relativity.

There is so much space up there that it is childish to think that in a peripheral corner of an ordinary galaxy there should be something uniquely special. Life on Earth gives only a small taste of what can happen in the universe. Our very soul itself is only one such small example.

The world described by the theory is thus further distanced from the one with which we are familiar. There is no longer space that "contains" the world, and there is no longer time "in which" events occur. There are only elementary processes wherein quanta of space and matter continually interact with one another.

Planets circle around the sun, and things fall, because space around them is curved.

A novel image of the world is taking shape: a world without space and without time. The space where the world "inhabits" and the time "along which" things evolve might soon disappear from our fundamental description of the physical world, in the same manner in which notions such as "the centre of the universe" have disappeared in the past.

When we say that the volume of a room is, for example, one hundred cubic meters, we are in effect counting the grains of space-the "quanta of the gravitational field"-that it contains. In a room, this number has more than one hundred digits. When we say that the area of this page is forty-five square inches, we are actually counting the number of links in the web, or loops, that traverse the page. Across the page of this book, there is a number of quanta with more or less seventy digits.

Even if we observe a small, empty region of space in which there are no atoms, we still detect a minute swarming of these particles.
