Quotes About Universe

If you wish to make an apple pie from scratch, you must first invent the universe.

Who is more humble? The scientist who looks at the universe with an open mind and accepts whatever the universe has to teach us, or somebody who says everything in this book must be considered the literal truth and never mind the fallibility of all the human beings involved?

The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself.

The universe is a pretty big place. If it's just us, seems like an awful waste of space.

The consequences of Thomson's Principle of Dissipation were elaborated by Hermann von Helmholtz, who two years later described the "heat death" of the universe, the consequence of the transformation of all energy into heat [14].

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.

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.

What are we, in this boundless and glowing world?

We are stories, contained within the twenty complicated centimeters behind our eyes, lines drawn by traces left by the (re)mingling together of things in the world, and oriented toward predicting events in the future, toward the direction of increasing entropy, in a rather particular corner of this immense, chaotic universe.

If things fall, it is due to this slowing down of time. Where time passes uniformly, in interplanetary space, things do not fall. They float, without falling. Here on the surface of our planet, on the other hand, the movement of things inclines naturally toward where time passes more slowly, as when we run down the beach into the sea and the resistance of the water on our legs makes us fall headfirst into the waves. Things fall downward because, down there, time is slowed by the Earth.

Space is created by the interaction of individual quanta of gravity.

Within the immense ocean of galaxies and stars we are in a remote corner; amidst the infinite arabesques of forms which constitute reality we are merely a flourish among innumerably many such flourishes.

The entropy of the world in the far past appears very low to us. But this might not reflect the exact state of the world: it might regard the subset of the world' s variables with which we, as physical systems, have interacted. It is with respect to the dramatic blurring produced by our interactions with the world, caused by the small set of macroscopic variables in terms of which we describe the world, that the entropy of the universe was low.

En el mar inmenso de galaxias y estrellas, somos un apartado rincón infinitesimal; entre los infinitos arabescos de formas que componen lo real, nosotros no somos más que un garabato entre muchos.

When Lemaître defends the idea that the universe is expanding, and Einstein does not believe it, one of the two is wrong; the other, right. All of Einstein's results, his fame, his influence on the scientific world, his immense authority, count for nothing. The observations prove him wrong, and it's game over. An obscure Belgian priest is right. It is for this reason that scientific thinking has power.

The fact that we live at the bottom of a deep gravity well, on the surface of a gas-covered planet going around a nuclear fireball 90 million miles away, and think this to be normal, is obviously some indication of how skewed our perspective tends to be.'104

Our "present" does not extend throughout the universe. It is like a bubble around us.

In technical terms, we say that Einstein has understood that "absolute simultaneity" does not exist: there is no collection of events in the universe that exist "now.

The quanta of gravity, that is, are not in space; they are themselves space. The

For a hypothetically supersensible being, there would be no "flowing" of time: the universe would be a single block of past, present, and future.

If LISA is launched, it should be able to see not only the gravitational waves produced by stars and black holes but also the diffuse background of primordial gravitational waves generated at a time close to the Big Bang. These waves should tell us about the quantum bounce. In the subtle irregularities of space, we should be able to find traces of events that took place fourteen billion years ago, at the origin of our universe, and confirm our deductions on the nature of space and time.

I want a theory of physics that accounts for the structure of the universe, that clarifies what it is to be an observer in the universe, not a theory that makes the universe depend on me observing it.

Every cubic centimeter of space, and every second that passes, is the result of this dancing foam of extremely small quanta.

Is the daily spectacle of a revolving universe "illusory"? No, it is real, but it doesn't involve the cosmos alone. It involves our relation with the sun and the stars. We understand it by asking ourselves how we move. Cosmic movement emerges from the relation between the cosmos and ourselves.
