„Myślę, że mogliby wyruszyć na potężnych statkach kosmicznych, splądrowawszy już i zużywszy wszystkie zasoby na swej macierzystej planecie. Tacy wysoko rozwinięci kosmici mogliby stać się nomadami w poszukiwaniu planet, znajdujących się w ich zasięgu, które mogliby podbić i skolonizować.”

O świetle

„Jesteśmy tylko szczególnie zaawansowaną w rozwoju odmianą małp na niezbyt ważnej planecie, krążącej wokół całkiem przeciętnego Słońca. Ale jesteśmy w stanie poznawać wszechświat. Dopiero to sprawia, że jesteśmy wyjątkowi.”

O wszechświecie , O przyszłości

„To niedorzeczność. Współczesna mechanika kwantowa opisująca ruch elektronów wystarczająco dokładnie objaśnia akt stworzenia. Na tyle dokładnie, że Boga możemy już włożyć między bajki.”

Stephen Hawking

Źródło: Marek Szenborn, Zbędny Bóg, „Fakty i Mity” nr 39/2010

O Bogu

„Z praw fizyki wynika nie tylko, że wszechświat mógł zaistnieć sam z siebie, niczym proton, i nie wymagało to włożenia żadnej energii, ale i że jest w pełni możliwe, iż Wielki Wybuch nie miał w ogóle przyczyny. Żadnej, ale to żadnej.”

O pewności siebie , O wszechświecie

„Można zdefiniować Boga jako uosobienie praw przyrody, ale to nie odpowiada temu, jak pojmuje Boga większość ludzi. Bóg jest dla nich istotą podobną człowiekowi, z którą mogą nawiązać osobową relacje. Gdy weźmiemy pod uwagę ogrom wszechświata i to, jak mało znaczące i przypadkowe jest w nim życie człowieka, wydaje się to czymś skrajnie mało prawdopodobnym.”

O relacjach , O ludziach , O życiu , O Bogu

„Każdy z nas ma swobodę, by wierzyć, w co tylko chce, jednak dla mnie najprostszym wyjaśnieniem jest, że Boga nie ma. Nikt nie stworzył wszechświata, nikt też nie kieruje ludzkimi losami. Przywodzi to mnie do głębokiej konstatacji, że najprawdopodobniej nie ma czegoś takiego jak niebo ani życie po życiu. Uważam wiarę w życie pozagrobowe co najwyżej za przykład myślenia życzeniowego, jako że nie ma na nie żadnych wiarygodnych dowodów i byłoby ono zasadniczo sprzeczne z całym dorobkiem nauki. Sądzę, że gdy umieramy, na powrót obracamy się w proch. Wszakże w pewnym sensie żyjemy nadal – w naszych dokonaniach oraz w genach, które przekazaliśmy swojemu potomstwu.”

Kontekst: Just like a computer, we must remember things in the order in which entropy increases. This makes the second law of thermodynamics almost trivial. Disorder increases with time because we measure time in the direction in which disorder increases. You can’t have a safer bet than that!

“Many people would claim that the boundary conditions are not part of physics but belong to metaphysics or religion. They would claim that nature had complete freedom to start the universe off any way it wanted.”

"The Quantum State of the Universe", Nuclear Physics (1984) 
Kontekst: Many people would claim that the boundary conditions are not part of physics but belong to metaphysics or religion. They would claim that nature had complete freedom to start the universe off any way it wanted. That may be so, but it could also have made it evolve in a completely arbitrary and random manner. Yet all the evidence is that it evolves in a regular way according to certain laws. It would therefore seem reasonable to suppose that there are also laws governing the boundary conditions.

“Today will still yearn to know why we are here and where we came from. Humanity's deepest desire for knowledge is justification enough for our continuing quest. And our goal is nothing less than a complete description of the universe we live in.”

“The human race is just a chemical scum on a moderate-sized planet, orbiting around a very average star in the outer suburb of one among a hundred billion galaxies. We are so insignificant that I can't believe the whole universe exists for our benefit. That would be like saying that you would disappear if I closed my eyes.”

“The universe would have expanded in a smooth way from a single point. As it expanded, it would have borrowed energy from the gravitational field, to create matter. As any economist could have predicted, the result of all that borrowing, was inflation. The universe expanded and borrowed at an ever-increasing rate. Fortunately, the debt of gravitational energy will not have to be repaid until the end of the universe.”

The Beginning of Time (1996)

“Einstein is the only figure in the physical sciences with a stature that can be compared with Newton. Newton is reported to have said "If I have seen further than other men, it is because I stood on the shoulders of giants." This remark is even more true of Einstein who stood on the shoulders of Newton. Both Newton and Einstein put forward a theory of mechanics and a theory of gravity but Einstein was able to base General Relativity on the mathematical theory of curved spaces that had been constructed by Riemann while Newton had to develop his own mathematical machinery. It is therefore appropriate to acclaim Newton as the greatest figure in mathematical physics and the Principia is his greatest achievement.”

The Beginning of Time (1996)

“We shouldn't be surprised that conditions in the universe are suitable for life, but this is not evidence that the universe was designed to allow for life. We could call order by the name of God, but it would be an impersonal God. There's not much personal about the laws of physics.”

“Someone told me that each equation I included in the book would halve the sales. I therefore resolved not to have any equations at all. In the end, however, I did put in one equation, Einstein's famous equation, E = mc^2. I hope that this will not scare off half of my potential readers.”

Interview with The Guardian (15 May 2011)

“What I have done is to show that it is possible for the way the universe began to be determined by the laws of science. In that case, it would not be necessary to appeal to God to decide how the universe began. This doesn't prove that there is no God, only that God is not necessary.”

Der Spiegel (17 October 1988)

“Because there is a law such as gravity, the universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the universe going.”

The Grand Design (2010)

“The subject of this book is the structure of space-time on length-scales from 10-13cm, the radius of an elementary particle, up to 1028cm, the radius of the universe. …we base our treatment on Einstein's General Theory of Relativity. This theory leads to two remarkable predictions about the universe: first, that the final fate of massive stars is to collapse behind an event horizon to form a 'black hole' which will contain a singularity; and secondly, that there is a singularity in our past which constitutes, in some sense, a beginning to the universe.”

“I regard [the many worlds interpretation] as self-evidently correct. [T. F.: Yet some don't find it evident to themselves. ] Yeah, well, there are some people who spend an awful lot of time talking about the interpretation of quantum mechanics.

Heard in person by this contributor when Hawking showed-up in a Caltech physics class taught by Robert Christy in 1980 or '81; when asked about collapse of the state-vector he whispered to his assistant Chris (surname unknown) something at which point Chris stood up and said 'Stephen is paraphrasing Herman Göring by saying "When I hear the words 'Schrödinger's Cat' I reach for my gun."'.
