matter was compressed into infinite densities. Instead, their average density was a reasonable number, though higher than ours. They had formed in the early moments of the universe and been forever isolated, living out microlives inside a folded geometry. Wickham’s new field equations showed they were out there, between the clusters of galaxies.
Abruptly he sat, feeling dizzy. An ache behind his eyes, spreading. Matter was swallowed into the net of space-time, of differential geometries. G times
Another set of bursts. He scribbled them on a pad. The scratching pen cut the silence.

and then the sea of noise again, the waves lost.
This all meant something to someone, but who? Where? When? Another:

Wrong language? A code from across the galaxy, from across the universe? This apparatus opened up communication with everywhere, everywhen, instantly. Talk to the stars. Talk to the compressed beings inside a dot of space. A telegram from Andromeda would take less time than one from London. Tachyons sleeted through the laboratory, through Renfrew, bringing word. It was within their grasp, if only they had time…
He shook his head. All form and structure was eroded by the overlapping of many voices, a chorus. Everyone was talking at once and no one could hear.
The roughing pumps coughed. Tachyons of size 10-13 centimeters were flashing across whole universes, across 1028 centimeters of cooling matter, in less time than Renfrew’s eye took to absorb a photon of the pale laboratory light. All distances and times were wound in upon each other, singularities sucking up the stuff of creation. Event horizons rippled and worlds coiled into worlds. There were voices in this room, voices clamoring, touching—
Renfrew stood up and suddenly clutched at a scope mount for support. Christ, the fever. It clawed at him, ran glowing smoke fingers through his mind.
ATTEMPT CONTACT FROM 2349. All thought of reaching the past was gone now, he realized, blinking. The room veered, then righted itself. With Markham gone and the Wickham woman missing for days, there was no longer even any hope of understanding what had happened. Causality’s leaden hand would win out. The soothing human world of flowing time would go on, a Sphinx yielding none of her secrets. An infinite series of grandfathers would live out their lives safe from Renfrew.
ATTEMPT CONTACT, the scope sputtered again.
But unless he knew where and when they were, there was no hope of answering.
Hello, 2349. Hello out there. This is 1998, an
Renfrew smiled with flinty irony Whispers came flitting, embedding soft words of tomorrow in the indium. Someone was there. Someone brought hope.
The room was cold. Renfrew huddled by his instruments, perspiring, peering at the bursts of waves. He was like a South Sea islander, watching the airplanes draw their stately lines across the sky, unable to shout up to them. I
He was trying a modification of the signal correlator when the lights winked out. Utter blackness rushed in. The distant generator rattled and chugged into silence.
It took a long time to feel his way out and into the light. It was a bleak, gray noon, but he did not notice; it was enough to be outside.
He could hear no sound from Cambridge at all. The breeze carried a sour tang. No birds. No aircraft.
He walked south, towards Grantchester. He looked back once at the low square profile of the Cav and in the diffused light he raised a hand to it. He thought of the nested universes, onion skin within onion skin. Leaning back, head swimming, he peered at the clouds, once so benign a sight. Above that cloak was the galaxy, a great swarm of colored lights, turning with majestic slowness in the great night. Then he looked down at the bumpy, worn footpath and felt a great weight lift from him. For so long now he had been transfixed by the past. It had deadened him to this real world around him. He knew, now, without knowing quite how he knew, that it was forever lost. Rather than feeling despair, he was elated, free.
Marjorie lay up ahead, no doubt frightened to be alone. He remembered her preserves on the uncompromising straight shelving, and smiled. They could eat those for some time. Have some easy meals together, as they did in the days before the children. They would soon have to go to the countryside and get Johnny and Nicky, of course.
Puffing slightly, his head clearing, he walked along the deserted path. There was really quite a lot ahead to do, when you thought about it.
CHAPTER FORTY SIX
HE WALKED FROM HIS HOTEL ON CONNECTICUT AVENUE. The reception was to be a buffet lunch, the letter said, so Gordon had slept in until eleven. He had long ago learned that on short trips to the east it was best to grant nothing to the myth of time zones, and keep to his western schedule. Invariably this fit the demands on an out-of-town visitor anyway, since such occasions were excuses for lingering over sauce-drenched entrees in expensive restaurants, followed by earnest, now-that-we’re-away-from-the-office-I-can-speak-frankly revelations over several cups of coffee, and then late night stumblings-to-bed. Arising at ten the next morning seldom got him to the NSF or AEC later than the executives themselves, since he ate no breakfast.
He tramped through the city zoo; it was more or less along the way. Yellow canine eyes followed him, contemplating the results if the bars were suddenly lifted. Chimps swung in pendulum strokes on an unending circuit of their cramped universe. The natural world was a pocket here amid distant honks and looming, square profiles of sour brown brick. Gordon savored the clammy fullness of the breeze that had tunneled its way up from the Potomac. He welcomed this traveler’s brush with the seasons, punctuations to the extended sentences of the months, a welcome relief from California’s monotonous excellence.
He had first come here with his mother and father. That tourist’s orbit was now a dim set of memories from a corner of his preadolescence, the period of life that he supposed was everybody’s golden age. He remembered being awed at the sleek white glow of the Washington Monument and the White House. For years afterward he was certain these solemn edifices were what was meant when his grammar school class sang “America” and chorused about alabaster majesties. “The country, it really begins in Washington,” his mother had said, not forgetting to add the pedagogical “D.C.,” so that her son would never confuse it with the state. And Gordon, towed through the list of historic shrines, saw what she meant. Beyond the Frenchified design of the city center lay a rural park, land that breathed of Jefferson and tree-traced boulevards. To him Washington had ever since been the entranceway to a vast republic where crops sprouted under a WASP sun. There, blue-eyed blonds drove yellow roadsters that left dust plumes on the open roads as they roared from one country fair to the next, women won prizes for strawberry preserves and men drank watery beer and kissed girls who had been struck from the template of Doris Day. He had gazed upward at the
Gordon thrust his hands into his pockets for warmth and walked. The corners of his mouth perked up in an
