“We are made of the same stardust of which all things are made, and when we are immersed in suffering or when we are experiencing intense joy we are being nothing other than what we can’t help but be: a part of our world.”
― Carlo Rovelli, Seven Brief Lessons on Physics

“This is time for us. Memory. A nostalgia. The pain of absence. But it isn't absence that causes sorrow. It is affection and love. Without affection, without love, such absences would cause us no pain.
For this reason, even the pain caused by absence is in the end something good and even beautiful. Because it feeds on that which gives meaning to life.”
― Carlo Rovelli, L'ordine del tempo

“In his youth Albert Einstein spent a year loafing aimlessly. You don't get anywhere by not 'wasting' time- something, unfortunately, that the parents of teenagers tend frequently to forget.”
― Carlo Rovelli, Seven Brief Lessons on Physics

“Genius hesitates.”
― Carlo Rovelli, Seven Brief Lessons on Physics

“Here, on the edge of what we know, in contact with the ocean of the unknown, shines the mystery and beauty of the world. And it’s breathtaking.”
― Carlo Rovelli, Seven Brief Lessons on Physics

“Because everything that begins must end. What causes us to suffer is not in the past or the future: it is here, now, in our memory, in our expectations. We long for timelessness, we endure the passing of time: we suffer time. Time is suffering.”
― Carlo Rovelli, L'ordine del tempo

“The very foundation of science is to keep the door open to doubt.”
― Carlo Rovelli

“We are perhaps the only species on Earth to be conscious of the inevitability of our individual mortality. I fear that soon we shall also have to become the only species that will knowingly watch the coming of its own collective demise, or at least the demise of its civilization.”
― Carlo Rovelli, Seven Brief Lessons on Physics

“I am my mother’s caresses, and the serene kindness with which my father calmly guided me; I am my adolescent travels; I am what my reading has deposited in layers in my mind; I am my loves, my moments of despair, my friendships, what I’ve written, what I’ve heard; the faces engraved on my memory. I am, above all, the one who a minute ago made a cup of tea for himself. The one who a moment ago typed the word “memory” into his computer. The one who just composed the sentence that I am now completing. If all this disappeared, would I still exist? I am this long, ongoing novel. My life consists of it.”
― Carlo Rovelli, L'ordine del tempo

“We are stories, contained within the twenty complicated centimeters behind our eyes...”
― Carlo Rovelli, L'ordine del tempo

“The atoms of our body, as well, flow in and away from us. We, like waves and like all objects, are a flux of events; we are processes, for a brief time monotonous”
― Carlo Rovelli, La realtà non è come ci appare: La struttura elementare delle cose

“We are made up of the same atoms and the same light signals as are exchanged between pine trees in the mountains and stars in the galaxies.”
― Carlo Rovelli, Seven Brief Lessons on Physics

“We understand the world in its becoming, not in its being.”
― Carlo Rovelli, L'ordine del tempo

“Ever since we discovered that Earth is round and turns like a mad spinning-top, we have understood that reality is not as it appears to us.”
― Carlo Rovelli, Seven Brief Lessons on Physics

“If I ask whether two events—one on Earth and the other on Proxima b—are happening “at the same moment,” the correct answer would be: “It’s a question that doesn’t make sense, because there is no such thing as ‘the same moment’ definable in the universe.” The “present of the universe” is meaningless.”
― Carlo Rovelli, The Order of Time

“There are frontiers where we are learning, and our desire for knowledge burns. They are in the most minute reaches of the fabric of space, at the origins of the cosmos, in the nature of time, in the phenomenon of black holes, and in the workings of our own thought processes. Here, on the edge of what we know, in contact with the ocean of the unknown, shines the mystery and the beauty of the world. And it’s breathtaking.”
― Carlo Rovelli, Seven Brief Lessons on Physics

“When Einstein died, his greatest rival, Bohr, found for him words of moving admiration. When a few years later Bohr in turn died, someone took a photograph of the blackboard in his study. There’s a drawing on it. A drawing of the ‘light-filled box’ in Einstein’s thought experiment. To the very last, the desire to challenge oneself and understand more. And to the very last: doubt”
― Carlo Rovelli, Seven Brief Lessons on Physics

“It is like the point where the rainbow touches the forest. We think that we can see it—but if we go to look for it, it isn’t there.”
― Carlo Rovelli, The Order of Time

“The ability to understand something before it’s observed is at the heart of scientific thinking.”
― Carlo Rovelli, The Order of Time

“It is hardly surprising that there are more things in heaven and earth, dear reader, than have been dreamed of in our philosophy - or in our physics.”
― Carlo Rovelli, Seven Brief Lessons on Physics

“Quantum mechanics and experiments with particles have taught us that the world is a continuous, restless swarming of things, a continuous coming to light and disappearance of ephemeral entities. A set of vibrations, as in the switched-on hippie world of the 1960s. A world of happenings, not of things. The”

“I remember a little girl...
But how can that be...
Once I was that little Resi,
and then one day I became an old woman?
...If God wills it so, why allow me to see it?
Why doesn't he hide it from me?
Everything is a mystery, such a deep mystery...
I feel the fragility of things in time.
From the bottom of my heart, I feel we should
cling to nothing.

Everything slips through our fingers.
All that we seek to hold on to dissolves.
Everything vanishes, like mist and dreams...
Time is a strange thing.
When we don't need it, it is nothing.
Then, suddenly, there is nothing else.
It is everywhere around us. Also within us.
It seeps into our faces.

It seeps into the mirror, runs through my temples...
Between you and I it runs silently, like an hourglass.
Oh, Quin Quin.
Sometimes I feel it flowing inexorably.
Sometimes I get up in the middle of the night
and stop all the clocks...”

“You don’t get to new places by following established tracks.”
― Carlo Rovelli, Reality Is Not What It Seems: The Journey to Quantum Gravity

“As human beings, we live by emotions and thoughts. We exchange them when we are in the same place at the same time, talking to each other, looking into each other's eyes, brushing against each other's skin. We are nourished by this network of encounters and exchanges. But, in reality, we do not need to be in the same place and time to have such exchanges. Thoughts and emotions that create bonds of attachment between us have no difficulty in crossing seas and decades, sometimes even centuries, tied to thin sheets of paper or dancing between the microchips of a computer. We are part of a network that goes far beyond the few days of our lives and the few square meters that we tread. This book is also a part of that weave...”

“Nature is our home, and in nature we are at home. This strange, multicoloured and astonishing world which we explore – where space is granular, time does not exist, and things are nowhere – is not something that estranges us from our true selves, for this is only what our natural curiosity reveals to us about the place of our dwelling. About the stuff of which we ourselves are made.”
― Carlo Rovelli, Seven Brief Lessons on Physics

“We are all in the depths of a cave, chained by our ignorance, by our prejudices, and our weak senses reveal to us only shadows. If we try to see further, we are confused; we are unaccustomed. But we try. This is science. Scientific”

“Compare ‘now’ with ‘here’. ‘Here’ designates the place where a speaker is: for two different people ‘here’ points to two different places. Consequently ‘here’ is a word the meaning of which depends on where it is spoken. The technical term for this kind of utterance is ‘indexical’. ‘Now’ also points to the instant in which the word is uttered and is also classed as ‘indexical’. But no one would dream of saying that things ‘here’ exist, whereas things that are not ‘here’ do not exist. So then why do we say that things that are 'now' exist and that everything else doesn't?”
― Carlo Rovelli, Seven Brief Lessons on Physics

“All of the sons of Adam are part of one single body, They are of the same essence. When time afflicts us with pain In one part of that body All the other parts feel it too. If you fail to feel the pain of others You do not deserve the name of man.”
― Carlo Rovelli, The Order of Time

“I believe that this example demonstrates how great science and great poetry are both visionary, and may even arrive at the same intuitions. Our culture is foolish to keep science and poetry separated: they are two tools to open our eyes to the complexity and beauty of the world.”
― Carlo Rovelli, Reality Is Not What It Seems: The Journey to Quantum Gravity

“This is the disconcerting conclusion that emerges from Boltzmann’s work: the difference between the past and the future refers only to our own blurred vision of the world. It’s a conclusion that leaves us flabbergasted: is it really possible that a perception so vivid, basic, existential—my perception of the passage of time—depends on the fact that I cannot apprehend the world in all of its minute detail? On a kind of distortion that’s produced by myopia? Is it true that, if I could see exactly and take into consideration the actual dance of millions of molecules, then the future would be “just like” the past?”
