Quotes About Gravity

The first planet that Cooper and his crew visit is Miller's. The most impressive things about this planet are the extreme slowing of time there, gigantic water waves, and huge tidal gravity. All three are related, and arise from the planet's closeness to Gargantua.

If we begin with the ill-understood laws of quantum gravity and then discard the fluctuations, we must obtain Einstein's well-understood relativistic laws of physics. The fluctuations we discard are, for example, a froth of fluctuating, exquisitely tiny wormholes ("quantum foam" that pervades all of space; Figure 26.3 and Chapter 14).

so matter as we know it gets stretched and squeezed out of existence.

Time, he realized, must be warped by the masses of heavy bodies such as the Earth or a black hole, and that warping is responsible for gravity. He embodied this insight in what I like to call "Einstein's law of time warps," a precise mathematical formula that I describe qualitatively this way: Everything likes to live where it will age the most slowly, and gravity pulls it there.

It has been said that arguing against globalization is like arguing against the laws of gravity.

Race, john powell says, is like gravity, experienced by all, understood by few.

The conviction grows in me that we shall discover laws of personality and behavior which are as significant for human progress or human understanding as the law of gravity or the laws of thermodynamics.

It is entropy, not energy, that keeps stones on the ground and the world turning.

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.

And it is at this point that an extraordinary idea occurred to him, a stroke of pure genius: the gravitational field is not diffused through space; the gravitational field is that space itself. This is the idea of the general theory of relativity. Newton's "space," through which things move, and the "gravitational field" are one and the same thing.

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

quantum mechanics cannot deal with the curvature of spacetime, and general relativity cannot account for quanta. This is the problem of quantum gravity.

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

a star must ignite for hydrogen to begin to burn there into helium. What causes stars to ignite? Another process that increases entropy: the contraction due to gravity of one of the large clouds of hydrogen that sail throughout the galaxy.

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.

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

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.

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.

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.
