alrightsnaps:“Other worlds?” John Faa said. “Pardon me, sir, but what worlds would those be? Do you mean the stars?”“Indeed no.”“Perhaps the world of spirits?” said Farder Coram.“Nor that.”“Is it the city in the lights?” said Lyra. “It is, en’t it?”The goose turned his stately head toward her. His eyes were black, surrounded by a thin line of pure sky-blue, and their gaze was intense.“Yes,” he said. “Witches have known of the other worlds for thousands of years. You can see them sometimes in the Northern Lights. They aren’t part of this universe at all; even the furthest stars are part of this universe, but the lights show us a different universe entirely. Not further away, but interpenetrating with this one. Here, on this deck, millions of other universes exist, unaware of one another….”He raised his wings and spread them wide before folding them again.“There,” he said, “I have just brushed ten million other worlds, and they knew nothing of it. We are as close as a heartbeat, but we can never touch or see or hear these other worlds except in the Northern Lights.”“And why there?” said Farder Coram.“Because the charged particles in the Aurora have the property of making the matter of this world thin, so that we can see through it for a brief time. Witches have always known this, but we seldom speak of it.”– His Dark Materials, Northern Lights -- source link
