Quotes About Universe

Al principio, aprendemos la verdad ínfima, la apreciamos en su justo valor, pero no debemos creer que esta es toda la verdad del universo

And sometimes I sit there late at night or early in the morning, and I think about the vastness of the ocean, of the sky, of the spaces between us and the nearest stars, about the incredible, unfathomable bigness of it all.

Trying to stop people from learning, sharing, and loving is a losing game because it means working against God and the plotline of God's universe.

The wonders of life and the universe are mere reflections of microscopic particles engaged in a pointless dance fully choreographed by the laws of physics.

The revelation we've come to is that we can trust our memories of a past with lower, not higher, entropy only if the big bang - the process, event, or happening that brought the universe into existence - started off the universe in an extraordinarily special, highly ordered state of low entropy.

But Einstein refused to be mathematics' pawn. He bucked the equations in favor of his intuition about how the cosmos should be, his deep-seated belief that the universe was eternal and, on the largest of scales, fixed and unchanging. The universe, Einstein admonished Lemaître, is not now expanding and never was.

Just as we envision all of space as really being out there, as really existing, we should also envision all of time as really being out there, as really existing too.

Even if we choose to use the nonstandard notion of distance and thereby describe the radius as being shorter than the Planck length, the physics we encounter—as discussed in previous sections—will be identical to that of a universe in which the radius, in the conventional sense of distance, is larger than the Planck length

A tree is to the entire universe as a string is to an atom.

And since, according to the big bang theory, the bang is what is supposed to have happened at the beginning, the big bang leaves out the bang. It tells us nothing about what banged, why it banged, how it banged, or, frankly, whether it ever really banged at all.

if an atom were magnified to be as large as the observable universe, the same magnification would make the Planck length the size of an average tree.

The beauty of physics, its raison d'etre, is that it offers insight into why things in the universe behave the way they do. The ability to predict behavior is a big part of the power of physics, but the heart of physics would be lost if it didn't give us a deep understanding of the hidden reality underlying what we observe.

Much as Hamlet famously declares, "I could be bounded in a nutshell, and count myself a king of infinite space," each of the bubble universes appears to have finite spatial extent when examined from the outside, but infinite spatial extent when examined from the inside. And that's a marvelous realization

all the labors of the ages, all the devotion, all the inspiration, all the noonday brightness of human genius, are destined to extinction in the vast death of the solar system, and that the whole temple of Man's achievement must inevitably be buried beneath the debris of a universe in ruins"?17

General relativity then establishes that objects move toward regions where time elapses more slowly; in a sense, all objects "want" to age as slowly as possible. From an Einsteinian perspective, that explains why an object falls when you let go of it.

If you were to head out into the cosmos, traveling ever farther, would you find that space goes on indefinitely, or that it abruptly ends?

Fused in stars and ejected in supernova explosions, or jettisoned by stellar collisions and amalgamated in particle plumes, an assortment of atomic species float through space, where they swirl together and coalesce into large clouds of gas, which over yet more time clump anew into stars and planets, and ultimately into us. Such is the origin of the ingredients constituting anything and everything you have ever encountered.

Since the familiar particles and the objects they compose—stars, planets, people, etc.—amount to less than 5 percent of the mass of the universe, such a disruption would not affect the vast majority of the universe, at least as measured by mass.

they are beyond each other's cosmic horizon.

En un universo infinito hay infinitas copias. En algunas, su doble está leyendo ahora esta frase, a la par que usted. En otras, se la ha saltado, o siente que necesita tomar algo y ha dejado el libro. Y en otras ..., bien, no tiene un carácter muy agradable y es alguien al que usted no gustaría encontrar en un callejón oscuro

The point being that everything emerges from the same collection of ingredients governed by the same physical principles. And those principles, as attested to by a few hundred years of observation, experimentation, and theorizing, will likely be expressed by a handful of symbols arranged in a small collection of mathematical equations. That is an elegant universe.

An informed appraisal of life absolutely require(s) a full understanding of life's arena–the universe. … By deepening our understanding of the true nature of physical reality, we profoundly reconfigure our sense of ourselves and our experience of the universe.

Black holes don't just tell us about how black holes store information. Black holes inform us about information storage in any context.

The equations are indifferent to the supposed freedom of human will. Some have taken this to mean that in a classical universe, free will would be an illusion. You are made of a collection of particles, so if the laws of classical physics could determine everything about your particles at any moment—where they'd be, how they'd be moving and so on—your willful ability to determine your own actions would appear fully compromised.
