Quotes About Space

the gravitational field is not diffused through space; the gravitational field is that space itself.

Even the distinction between present, past, and future thus becomes fluctuating, indeterminate. Just as a particle may be diffused in space, so, too, the differences between past and future may fluctuate: an event may be both before and after another one.

Newton, who resuscitated the Democritean idea of space, had tried to patch things up by arguing that space was God's sensorium. No one has ever understood what Newton meant by 'God's sensorium', perhaps not even Newton himself.

Where time passes uniformly, in interplanetary space, things do not fall.

Quantum gravity is the discovery that no infinitely small point exists. There is a lower limit to the divisibility of space.

Solen böjer rummet runt omkring sig och jorden kretsar inte kring den för att den vore dragen av en gåtfull kraft, utan för att den rör sig rakt fram i ett rum som böjs.

But on the moon, the duration of the "extended present" is a few seconds, and on Mars it is a quarter of an hour. This means we can say that on Mars there are events that in this precise moment have already happened, events that are yet to happen, but also a quarter-of-an-hour of events during which things occur that are neither in our past nor in our future.

Einstein predicted that time passes more quickly high up than below, nearer to Earth. This was measured and turned out to be the case. If a person who has lived at sea level meets up with his twin who has lived in the mountains, he will find that his sibling is slightly older than he. And this is just the beginning.

the "singularity" that classic general relativity anticipated disappears as soon as we take quantum gravity into account.

Loop theory describes this atomic and granular quantum structure of space in a precise mathematical form. It is obtained by applying the general equations of quantum mechanics written by Dirac to Einstein's gravitational field. In particular, loop theory specifies that volume (for example the volume of a given cube) cannot be arbitrarily small. A minimum volume exists. No space smaller than this minimum volume exists. There is a minimum "quantum" of volume: an elementary atom of space.

Non c'è più lo spazio che «contiene» il mondo e non c'è più il tempo «lungo il quale» avvengono gli eventi. Ci sono solo processi elementari dove quanti di spazio e materia interagiscono tra loro in continuazione. L'illusione dello spazio e del tempo continui attorno a noi è la visione sfocata di questo fitto pullulare di processi elementari.

Einstein wrote an equation that says that R is equivalent to the energy of matter. That is to say: space curves where there is matter. That is it. The equation fits into half a line, and there is nothing more. A vision—that space curves—became an equation.

Einstein's equation shows that space cannot stand still; it must be expanding. In 1930 the expansion of the universe was actually observed.

All of this is the result of an elementary intuition: that space and gravitational field are the same thing.

In quantum mechanics no object has a definite position, except when colliding headlong with something else. In order to describe it in mid-flight, between one interaction and another, we use an abstract mathematical formula that has no existence in real space, only in abstract mathematical space.

Stars burn as long as they have available hydrogen—their fuel—then die out. The remaining material is no longer supported by the pressure of the heat and collapses under its own weight. When this happens to a large enough star, the weight is so strong that matter is squashed down to an enormous degree, and space curves so intensely as to plunge down into an actual hole. A black hole.

O amor é grande e cabe nesta janela sobre o mar. O mar é grande e cabe na cama e no colchão de amar. O amor é grande e cabe no breve espaço de beijar.

You're in my personal space, so get out of it.

The Death Star and its Sanctuary Moon hang distant in space as the Rebel fleet comes out of hyperspace with an awesome roar.

I feel that my father's greatest legacy was the people he inspired to get involved in public service and their communities, to join the Peace Corps, to go into space. And really that generation transformed this country in civil rights, social justice, the economy and everything.

I know when you need your space. That's why I got the beard.

As we all know, there is no underwear in space.

Anyway, George comes up to me the first day of filming and he takes one look at the dress and says, "You can't wear a bra under that dress." So, I say, "Okay, I'll bite. Why?" And he says, "Because . . . there's no underwear in space." I promise you this is true, and he says it with such conviction too! Like he had been to space and looked around and he didn't see any bras or panties or briefs anywhere.

But George actually does have a point, because you know when they send out those space probes and they beam back footage of what it looks like up there? All those films ever show are sand and rocks. I've never seen a bra in any of that footage.
