“MacDonald paused outside the long, low concrete building which housed the offices and laboratories and computers. It was twilight. The sun had descended below the green hills, but orange and purpling wisps of cirrus trailed down the western sky.

“Between MacDonald and the sky was a giant dish held aloft by skeleton metal fingers — held high as if to catch the stardust that drifted down at night from the Milky Way.

Go and catch a falling star,
Get with child a mandrake root,
Tell me where all past years are,
Or who cleft the Devil’s foot;
Teach me to hear mermaids singing,
Or to keep off envy’s stinging,
And find
What wind
Serves to advance an honest mind.

“Then the dish began to turn, noiselessly, incredibly, and to tip. And it was not a dish any more but an ear, a listening ear cupped by the surrounding hills to overhear the whispering universe.

“Perhaps this was what kept them at their jobs, MacDonald thought. In spite of all disappointments, in spite of all vain efforts, perhaps it was this massive machinery, as sensitive as their fingertips, which kept them struggling with the unfathomable. When they grew weary at their electronic listening posts, when their eyes grew dim with looking at unrevealing dials and studying uneventful graphs, they could step outside their concrete cells and renew their dull spirits in communion with the giant mechanism they commanded, the silent, sensing instrument in which the smallest packets of energy, the smallest waves of matter, were detected in their headlong, eternal flight across the universe. It was the stethoscope with which they took the pulse of the all and noted the birth and death of stars, the probe with which, here on an insignificant planet of an undistinguished star on the edge of the galaxy, they explored the infinite.

“Or perhaps it was not just the reality but the imagery, like poetry, which soothed their doubting souls, the bowl help up to catch Donne’s falling star, the ear cocked to catch the suspected shout that faded to an indistinguishable murmur by the time it reached them…”
