Quotes About Cosmos

We were told that you can never get something for nothing. But now, after a lifetime of work, I think that actually you can get a whole universe for free.

If the boundary condition of the universe is that it has no boundary in imaginary time, it won't have just a single history. There are many histories in imaginary time and each of them will determine a history in real time. Thus we have a superabundance of histories for the universe. What picks out the particular history, or set of histories that we live in, from the set of all possible histories of the universe?

THE ORIGIN OF THE UNIVERSE

Eine große Offenbarung des Weltraumzeitalters bestand darin, dass es der Menschheit die Sicht auf sich selbst ermöglichte. Betrachten wir die Erde vom All aus, sehen wir uns selbst als Ganzes. Wir nehmen die Einheit wahr und nicht das Trennende. Ein einfaches Bild mit einer unwiderlegbaren Botschaft: ein Planet, eine Menschheit.

Segundo algumas teorias, o universo que vivenciamos é apenas uma superfície quadridimensional em um espaço com dez ou onze dimensões. O filme Interestelar dá uma ideia de como isso funcionaria. Nós não veríamos essas dimensões extras porque a luz não se propagaria por elas, mas apenas pelas quatro dimensões do nosso universo.

All the evidence points to God being an inveterate gambler, who throws the dice on every possible occasion.

The laws of science determine the evolution of the universe, given its state at one time.

Newton gave us answers. Hawking gave us questions. And Hawking's questions themselves keep on giving, generating breakthroughs decades later. When ultimately we master the quantum gravity laws, and comprehend fully the birth of our universe, it may largely be by standing on the shoulders of Hawking." •

Stephen's answers to six of the questions are deeply rooted in his science. (Is there a God? How did it all begin? Can we predict the future? What is inside a black hole? Is time travel possible? How do we shape the future?).

El principio antrópico dice que el universo tiene que ser más o menos como lo vemos, porque si fuera diferente no habría nadie para observarlo.

Laplace suggested that there should be a set of scientific laws that would allow us to predict everything that would happen in the universe, if only we knew the complete state of the universe at one time.

Aristarchus suspected that this was the case and believed that the stars we see in the night sky are actually nothing more than distant suns.

if you believe that the universe is not arbitrary, but is governed by definite laws, you ultimately have to combine the partial theories into a complete unified theory that will describe everything in the universe.

Dios no solo juega a los dados, a veces los tira donde no se pueden ver.

After all, it is hard to think of a more important, or fundamental, mystery than what, or who, created and controls the universe.

the light that we see from distant galaxies left them millions of years ago, and in the case of the most distant object that we have seen, the light left some eight thousand million years ago. Thus, when we look at the universe, we are seeing it as it was in the past.

Apa yang Tuhan lakukan sebelum Dia menciptakan alam semesta? Agustinus tak menjawab: Dia mempersiapkan Neraka untuk orang-orang yang bertanya seperti itu. Dia malah mengatakan bahwa waktu adalah bagian alam semesta yang Tuhan ciptakan, dan waktu tidak ada sebelum permulaan alam semesta.

The great mystery at the heart of the Big Bang is to explain how an entire, fantastically enormous universe of space and energy can materialise out of nothing. The secret lies in one of the strangest facts about our cosmos. The laws of physics demand the existence of something called "negative energy.

Alam semesta mengembang tidak melenyapkan pencipta, tapi jelas membatasi kapan pencipta bisa melakukan penciptaan!

There is no God. No-one directs the universe.
