Quotes About Space

Pluto is about 40 AUs from us, the heart of the Oort cloud about fifty thousand. In a word, it is remote. But

The Earth at last had a position in space.

space being spacious, the average distance between any two of these civilizations is reckoned to be at least two hundred light years, which is a great deal more than merely saying it makes it sound.

What an interesting and exciting thought. We may be only one of millions of advanced civilizations. Unfortunately, space being spacious, the average distance between any two of these civilizations is reckoned to be at least two hundred light-years, which is a great deal more than merely saying it makes it sound.

That's not because it would take too long to get there—though of course it would—but because even if you travelled outward and outward in a straight line, indefinitely and pugnaciously, you would never arrive at an outer boundary. Instead, you would come back to where you began (at which point, presumably, you would rather lose heart in the exercise and give up).

In some sense, gravity does not exist28; what moves the planets and stars is the distortion of space and time.

Most schoolroom charts show the planets coming one after the other at neighborly intervals—the outer giants actually cast shadows over each other in many illustrations—but this is a necessary deceit to get them all on the same piece of paper. Neptune in reality isn't just a little bit beyond Jupiter, it's way beyond Jupiter—five times farther from Jupiter than Jupiter is from us, so far out that it receives only 3 percent as much sunlight as Jupiter.

a diagram of the solar system to scale, with Earth reduced to about the diameter of a pea, Jupiter would be over a thousand feet away and Pluto would be a mile and a half distant (and about the size of a bacterium, so you wouldn't be able to see it anyway).

electrons are not like orbiting planets at all, but more like the blades of a spinning fan, managing to fill every bit of space in their orbits simultaneously (but with the crucial difference that the blades of a fan only seem to be everywhere at once; electrons are).

Space, let me repeat, is enormous. The average distance between stars out there is 20 million million miles. Even at speeds approaching those of light, these are fantastically challenging distances for any traveling individual.

According to the new theory, an electron moving between orbits would disappear from one and reappear instantaneously in another without visiting the space between

that if you looked deep enough into space you should find some cosmic background radiation left over from the Big Bang.

On a diagram of the solar system to scale, with Earth reduced to about the diameter of a pea, Jupiter would be over a thousand feet away and Pluto would be a mile and a half distant (and about the size of a bacterium, so you wouldn't be able to see it anyway).

beyond a network of pedestrian tunnels and over a large open space shared by parking lots and those strange new-town trees that never seem to grow.

what moves the planets and stars is the distortion of space and time." Of

Astronomers today believe there are perhaps 140 billion galaxies in the visible universe.

Even in walking across the room you will very slightly alter your own experience of time and space.

The biggest component in any human, filling 61 percent of available space, is oxygen. It may seem a touch counterintuitive that we are almost two-thirds composed of an odorless gas.

no less than 99.5 per cent of the world's habitable space by volume, according to one estimate, is fundamentally—in practical terms completely—off limits to us. It

It appears that the universe may not only be filled with dark matter, but with dark energy.

Alpha Centauri

The point to remember, of course, when considering the universe at large is that we don't actually know what is in our own solar system. Now

the average asteroid actually will be about one and a half million kilometres from its nearest neighbour.

when we peer into the distance some of the galaxies we see may simply be reflections, ghost images created by rebounded light.
