And when the universe has finished exploding, all the stars will slow down, like a ball that has been thrown into the air, and they will come to a halt and they will all begin to fall towards the centre of the universe again. And then there will be nothing to stop us from seeing all the stars in the world because they will all be moving towards us, gradually faster and faster, and we will know that the world is going to end soon because when we look up into the sky at night there will be no darkness, just the blazing light of billions and billions of stars, all falling.

He thrust his hands out, right, left, and placed them on the outlines upon the desk. At once, he had the illusion of another pair of hands holding his. His senses extended, and he could see Gaia in all directions, green and moist, the Gaians still watching. When he willed himself to look upward, he saw a largely cloudy sky. Again, at his will, the clouds vanished and he looked at an unbroken blue sky with the orb of Gaia's sun filtered out.

Again he willed and the blue parted and he saw the stars. He wiped them out, and willed and saw the Galaxy, like a foreshortened pinwheel. He tested the computerized image, adjusting its orientation, altering the apparent progress of time, making it spin first in one direction, then the other. He located the sun of Sayshell, the nearest important star to Gaia; then the sun of Terminus; then of Trantor; one after the other. He traveled from star to star in the Galactic map that dwelt in the bowels of the computer.

Then he withdrew his hands and let the world of reality surround him again.

The introjection of symboling into primate social life was revolutionary. Everything was transformed, everything acquired new meaning; the symbol added a new dimension to primate—now human—existence. An ax was no longer merely a tool with which to chop; it could become a symbol of authority. Mating became marriage, and all social relationships between parents and children and brothers and sisters became moral obligations, duties, rights, and privileges. The world of nature, from the stones beside the path to the stars in their courses, became alive and conscious spirits. “And all that I beheld respired with inward meaning” (Wordsworth). The anthropoid had at last become a man.

The Hungarian mathematician Paul Erdos used to describe himself as a “machine for turning coffee into theorems”. In much the same way, genes are machines for turning stars into a bird's compass; carotenoids into males of dazzling beauty; smells into love-potions; facial muscles into signals of friendship; a glance into uncertainty of paternity; and oxygen, water, light, zinc, calcium and iron into bears, beetles, bacteria or bluebells. More strictly, genes are machines for turning stars into birds and thereby into more genes.

Colorless green ideas sleep furiously.

Then shall happen what seems great tidings: the Wolf shall swallow the sun; and this shall seem to men a great harm. Then the other wolf shall seize the moon, and he also shall work great ruin; the stars shall vanish from the heavens. Then shall come to pass these tidings also: all the earth shall tremble so, and the crags, that trees shall be torn up from the earth, and the crags fall to ruin; and all fetters and bonds shall be broken and rent. Then shall Fenris-Wolf get loose; then the sea shall gush forth upon the land, because the Midgard Serpent stirs in giant wrath and advances up onto the land. Then that too shall happen, that Naglfar shall be loosened, the ship which is so named. (It is made of dead men's nails; wherefore a warning is desirable, that if a man die with unshorn nails, that man adds much material to the ship Naglfar, which gods and men were fain to have finished late.) Yet in this sea-flood Naglfar shall float. Hrymr is the name of the giant who steers Naglfar. Fenris-Wolf shall advance with gaping mouth, and his lower jaw shall be against the earth, but the upper against heaven,—he would gape yet more if there were room for it; fires blaze from his eyes and nostrils.

Emacs outshines all other editing software in approximately the same way that the noonday sun does the stars. It is not just bigger and brighter; it simply makes everything else vanish.

Far away in the heavenly abode of the great god Indra, there is a wonderful net which has been hung by some cunning artificer in such a manner that it stretches out indefinitely in all directions. In accordance with the extravagant tastes of deities, the artificer has hung a single glittering jewel at the net's every node, and since the net itself is infinite in dimension, the jewels are infinite in number. There hang the jewels, glittering like stars of the first magnitude, a wonderful sight to behold. If we now arbitrarily select one of these jewels for inspection and look closely at it, we will discover that in its polished surface there are reflected all the other jewels in the net, infinite in number. Not only that, but each of the jewels reflected in this one jewel is also reflecting all the other jewels, so that the process of reflection is infinite.
