Quotes About Space

Büyük bir y?ld?z tüm yak?t?n? (hidrojeni) tüketti?inde sönmeye ba?lar. Geriye kalanlar, yanmadan kaynaklanan ?s?yla ayakta kalamaz, kendi a??rl???yla çöker, uzay? o kadar güçlü bir biçimde e?er ki gerçek bir deli?e dü?er. Bunlar ünlü karadeliklerdir.

What are the elementary "atoms" that vibrate, making a black hole hot? Hawking left this problem unanswered. Loop theory provides a possible answer. The elementary "atoms" of a black hole that vibrate, responsible for its temperature, are the individual quanta of space on its surface.

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

Hold on tight, because we are about to take off. "NOW" MEANS NOTHING What is happening "now" in a distant place? Imagine, for example, that your sister has gone to Proxima b, the recently discovered planet that orbits a star at approximately four light-years' distance from us. What is your sister doing now on Proxima b? The only correct answer is that the question makes no sense. It is like asking "What is here, in Beijing?" when we are in Venice.

There is no "truer" time; there are two times and they change relative to each other. Neither is truer than the other. But there are not just two times. Times are legion: a different one for every point in space. There is not one single time; there is a vast multitude of them.

Proper time" depends not only on where you are and your degree of proximity to masses; it depends also on the speed at which you move. It's a strange enough fact in itself, but its consequences are extraordinary. Hold on tight, because we are about to take

We are processes, events, composite and limited in space and time. But if we are not an individual entity, what is it that founds our identity and its unity?

the spatiotemporal entity of Einstein.

The sun bends space around itself, and Earth does not turn around it because of a mysterious force but because it is racing directly in a space that inclines, like a marble that rolls in a funnel. There are no mysterious forces generated at the center of the funnel; it is the curved nature of the walls that causes the marble to roll. Planets circle around the sun, and things fall, because space curves.

The key fact that Einstein understood is that this quarter of an hour is inevitable: there is no way of reducing it. It is woven into the texture of the events of space and of time: we cannot abbreviate it, any more than we can send a letter to the past.

An idea was needed, a great idea, a grand vision, to grasp the hidden order of the world. Leucippus and Democritus came up with this idea. The idea of Democritus's system is extremely simple: the entire universe is made up of a boundless space in which innumerable atoms run. Space is without limits; has neither an above nor a below; is without a center or a boundary. Atoms have no qualities at all, apart from their shape. They

Physical space is the fabric resulting from the ceaseless swarming of this web of relations. The lines themselves are nowhere-they are not in a place but rather create places through their interactions. Space is created by the interaction of individual quanta of gravity.

The present is a localized rather than a global phenomenon.

But it is not only space that curves: time does too. Einstein predicts that time on Earth passes more quickly at higher altitude, and more slowly at lower altitude.

Newton nesnelerin uzayda hareket etti?ini, uzay?n da bo? bir kap, evren için büyük bir kutu oldu?unu hayal etmi?ti. Newton taraf?ndan icat edilen bu "uzay"?n, dünyan?n kutusunun neden yap?ld??? da belli de?ildi.

Kütle çekim alan? uzayda yay?lm?? de?ildi, çekim alan? uzay?n ta kendisiydi.

Uzay maddenin var olduÄŸu yerde eÄŸrilir.

Ama bükülen yaln?zca uzay de?ildir; zaman da bükülür. Einstein zaman?n yüksekteki bir konumda, dünyaya yak?n, daha alçak bir durumdan daha h?zl? akt???n? öngörür.

The quanta of gravity, that is, are not in space; they are themselves space. The spin networks that describe the quantum structure of the gravitational field are not immersed in space, they do not inhabit a space. The location of single quanta of space is not defined with regard to something else, but only by the links, and the relation these express.

Einstein'?n denklemi uzay?n dura?an olamayaca??n?, geni?lemek zorunda oldu?unu gösterir. (...) Ayn? denklem geni?lemenin minicik ve çok s?cak genç bir evrenin patlamas?yla tetiklendi?ini de öngörür: Bu da Büyük Patlama'd?r.

There is our past: all the events that happened before what we can witness now. There is our future: the events that will happen after the moment from which we can see the here and now. Between this past and this future there is an interval that is neither past nor future and still has a duration: fifteen minutes on Mars; eight years on Proxima b; millions of years in the Andromeda galaxy. It is the expanded present.28 It is perhaps the greatest and strangest of Einstein's discoveries.

Evrenlerin patlad???, uzay?n ç?k??? olmayan delikler içine çöktü?ü, zaman?n bir gezegene inildikçe yava?lad???, y?ld?zlararas? uzay?n uçsuz bucaks?z enginli?inin deniz yüzeyi gibi dalgaland??? renkli ve ?a??rt?c? bir dünya...

Without this attraction, every celestial body would move in a straight line. So the universe, then, is a large space where bodies attract one another by means of forces; and there is a universal force, gravity: every body attracts every other body.

Black hole heat is directly connected to loop quantum gravity's fluctuations of the atoms of space.
