Einstein's Bridge

by Cramer, John

  Belinda noticed that several people stood and walked quickly to the wall telephones in the lobby.

  “Here’s a bulletin. The Texas Rangers report no, repeat, no evidence of radioactivity or dangerous chemical agents at the edges of the problem area. Reports that the Superconducting Super Collider has exploded are also being denied.”

  Belinda blinked. Somebody thinks the SSC exploded? The office telephones must be ringing up a storm. I’d better get back to the office, she thought. She quickly finished her salad, gulped down the last of the Diet Coke, and slid her tray into the rack. As she walked toward the exit along with several other people, she noticed that the gray cloud from the east seemed nearer.

  “Here’s another bulletin,” said the reporter. “The Governor has requested that all members of the Texas National Guard in the Dallas-Fort-Worth Area report to their headquarters units immediately.”

  Belinda stopped by the cafeteria exit and listened. Others pushed past her and hurried outside.

  “OK, folks,” said the reporter, “we’ve finally received authorization from the D/FW Air Traffic Controller to fly over the problem area and have a look-see. Here we go. I can see down below us that the traffic on Interstate 45 is completely stalled. There are stopped cars all over the freeway, and many collisions. Some of the cars are burning. I can see some bodies. None of them are moving. There seem to be some large black things moving among the cars.”

  What in the world is it, Belinda wondered. Some kind of nerve gas attack? It sounds worse than what happened in Bangkok last year.

  “We’re flying toward the densest part of the gray cloud now,” the reporter said. “It seems to be centered north of Ennis. Something is hitting our front window now. They seem to be small silvery objects with wings, perhaps flying insects. Maybe I can catch one. They ...”

  The voice stopped, and shortly afterward the helicopter engine noise halted. Another voice came on the radio, “We’re having technical difficulties. Please stay tuned,” it said.

  Belinda hurried through the cafeteria door and walked rapidly down the walkway, away from the parking lot where others seemed to be hurrying. Along the gravel path by the brook something was rustling in the trees. It looked like a swarm of metallic insects. One of them landed on her arm. Belinda reached down to brush it off and froze in mid-stride.

  She fell into darkness.

  CHAPTER 6.11

  Timelike Loop

  ROGER had argued with the others about how to approach the last maintenance station. He and Whitey wanted to blast through at top speed. George suggested approaching more slowly. Iris favored George’s strategy and finally convinced Roger and Whitey. When they reached the station, Whitey turned off the vehicle’s running lights and eased the truck forward at low speed, listening.

  As they reached the edge of the shaft, Roger heard a buzz. Looking upward, he saw a new swarm of Hive flyers, these much lower. The maintenance truck moved slowly across the open area beneath the shaft. Near the top of the opening, Roger could see large dark shapes moving down the walls of the shaft. He thought of Alice, and felt a sinking fear.

  The flyers ignored them at first. Then, as if reaching some consensus, the swarm began to drop down the shaft. Whitey pushed the accelerator control all the way forward and the vehicle began to pick up speed.

  George took the Bridge detector from his pocket and pointed it like a weapon at the wall above the double line of long cylindrical dipole magnets that made a two-layer stack on the right side of the tunnel. The bright blue cutting beam sprang from the device, and he slashed it downward, first through cryogenic plumbing above the magnets, and then through the thin-walled magnet cylinders themselves.

  The magnets of the great accelerator contained large reservoirs of cryogenic liquids, a reservoir of liquid helium encased in a blanket of liquid nitrogen. The ultra-cold fluids exploded outward into the tunnel behind the speeding vehicle. Roger looked backward at the steam clouds of condensed water vapor produced by the outpouring of ultra-cold. Through the steam clouds, he could see the Hive flyers hit the wall of ultra-cold gas and drop to the floor of the tunnel. “The SSC will never be the same,” Roger said.

  In another ten minutes they had reached the injection line branch, where the beam from the injector joined the main SSC ring. Whitey halted the vehicle, and they climbed out. He looked back down the tunnel. “Those damn critters will be here soon,” he said. “I’d better wait right here and stop ‘em.” He walked to the back of the truck and began to unload gas cylinders.

  “You can’t do that,” said Iris. “Their merest touch would be fatal. There’s nothing you can do.”

  Whitey smiled. “Oh yes there is, Ma’am. I was a demolition specialist in the Marine Corps durin’ the Gulf War. I know how to blow the hell outa things better’n just about anybody. These gas bottles are full’a hydrogen, oxygen, and methane. And the truck carries big cans of acetone, xylene, and alcohol. For solvents, y’know? Just give me a few minutes, and I can rig a pretty nice reception for those Hive critters when they come down the tunnel. I’m just sorry you folks can’t stay to enjoy the fireworks. But you’d better get on with your bidness and leave me to do mine.

  “Go on now. Get on up that branch tunnel. Time’s a’wastin.”

  They shook hands with Whitey, and George led the way up the sloping tunnel. Finally they reached the injector itself, which was buried in a curving tunnel at a higher level. George led the way along the curving walls to the injector power supply room, a stubby cylinder carved into the Austin Chalk stratum.

  He pointed to the large motor-generators that towered above them, making a high whining noise as they spun. “These,” he said, “turn huge vacuum-enclosed flywheels. The SSC injector is made of normal non-superconducting magnets that receive the beam and dump energy from the flywheels to the magnetic fields as they ramp up to accelerate it. Then they eject the beam and ramp back down, putting most of the stored energy from the magnetic fields back into the flywheels. The energy flows back and forth like that, with new energy from the power lines brought in continuously to make up for the losses due to bearing friction, coil resistance, and eddy currents. You’ll find more electrical energy available here than anywhere else in the whole accelerator, even though this is only the injector part. Most of the rest of the power goes into cryogenics which is distributed all around the ring.”

  Iris held her fingers about two centimeters apart. “I will need a gap about this size across which the electrical energy will flow.” she said above the whine of the generators.

  George nodded and led the way across the room to an area that was surrounded by a wire fence. His blue laser beam chewed through the lock on the gate. Inside the gate he moved a long aluminum shorting pole out of the way and walked to the back wall of the enclosure. “This is the area,” he said, “ where, in case of an electrical emergency, the total electrical energy of the machine can be dumped into a dummy load, a large tank filled with water that is vaporized by the dumped energy and vented off. If I cut here and here,” he indicated two thick copper bus bars, “and bend them to form a gap, you’ll have what you want. See the button over there?” he indicated a large red button with a glass cover outside the cage. “It triggers thyristors that will dump all the power here. Shall I do it?”

  Iris nodded. George cut the copper bars with the laser, then found a large wrench and bent them until their shiny cut surfaces were separated by about two centimeters, held at that gap by a scrap of plastic insulation.

  Then he walked outside the cage to the red button. He removed the plastic cover, so that the button was exposed. “We need a way to push this to dump the power.”

  “Do not concern yourself, I will deal with that,” said Iris.

  As she spoke, there was a very bright flash of light, followed shortly by a deep and very loud “whump” sound from the branch tunnel. />
  “Whitey was a good man,” said Roger.

  Iris walked to the distorted bus bars, and her face contorted. She extracted a small pink sphere from her mouth. It seemed to have flecks of bright red blood on it. “This is the Bridge I have carried,” she said. “My contact with the Makers is broken for the first time. It is very strange to be so alone. You humans must be very strong to bear it continuously.” She placed the sphere on the block of plastic in the gap.

  “Now let me explain,” she said. “When you trigger the discharge, this Bridgehead will momentarily expand. At the same time, its twin Bridgehead in the scintillator unit on the other side of the ring will be connected to a new fluctuation Bridge extracted from the quantum vacuum of your bubble, a Bridge selected because it spans an interval about seventeen of your years into the past. The two Bridgeheads in the Maker Universe will be joined and their connection with the Maker Bubble released. This will be done all in one operation.

  “The result will be the creation of a Bridge that makes a timelike loop, one Bridgehead here and the other about seventeen years in your past. This Bridgehead here will expand and dissipate as the singularity forms and goes to completion. During this process, because the singularity annihilates the intervening space-time, both Bridgeheads will momentarily be in the same place. If we succeed, since the present no longer exists you will be propelled back through the Bridge to the beginning of the loop, to the site of the Bridgehead in the past.”

  “You say ‘you’, not ‘we’,” said George. “Aren’t you coming with us?”

  “I cannot,” said Iris. “This body is a temporary thing, and its processes were regulated through the Bridgehead that I carried. That link is now broken, and I am dying. It is well. I would not be able to bear this isolation, if I could not see its end approaching. If you stand close to the Bridgehead, within about five meters, you should be projected through the time-hole. I will go and press the red button that starts the process..” She turned and walked toward the fence gate.

  “But,” Roger objected, “we’re a hundred meters underground. If we arrive at a time where there’s no SSC tunnel down here, we’ll be trapped in solid limestone.”

  Iris stopped. “The other Bridgehead will not be located here,” she said. “I suggested to our engineers that the Bridgehead in the past should be located at the site where you hatched my Egg. We have good coordinates for that location. You will be deposited above the water there and will have to swim to shore.”

  “I’m not a great swimmer,” said Roger, “and the water will ruin my computer. Let me make a float.” He raced across the room, grabbed a large plastic garbage bag from a workbench, and returned to the enclosure. He removed his backpack, placed it in the bag, and knotted the end, trapping considerable air inside. He held this to his chest.

  “Then prepare yourselves,” said Iris. She walked to the gate, then paused by the door. “I hear something outside.” She moved closer to the closed door and stood listening. “Hive creatures,” she said.

  As Roger watched, the door seemed to melt. Behind it was a gray fog. Hive flyers and a myriad of other creatures began to fly or crawl into the room. “I cannot destroy them, but perhaps I can delay them,” Iris said. “I am sorry, but one of you will have to press the red button.” The child stood before the them, her palms extended forward. Hive creatures touched her and dropped to the floor. Soon there was a large pile at her feet. Behind the open doorway large dark shapes were moving forward. Roger would remember those shapes in his nightmares. “You go on, George,” he said. “I’ll stay and press the button.”

  George grabbed Roger’s shoulder and stopped him. Then he picked up the long metal shorting pole that lay on the floor, fed it through the wire mesh of the caged-off area, and shoved its end against the red button.

  There was a blinding blue-green flash, ... and the universe ended.

  “I doubt if there is a Member of the Senate who really understands to any degree what the SSC is all about ...

  “Everything from the computer to television has come as a result of high-energy physics undertaken in this country. Between 20% and 30% of the gross national product of the United States comes from high energy physics.”

  — Senator Phil Gramm (R - Texas)

  “(The SSC) will revolutionize the computer industry, the medical community, and transform our industrial and technological base. Economic opportunities never anticipated will arise, scientific advancements never predicted will proceed and educational worlds never explored will emerge. Even if the original scientific goals are not completely met, the knowledge gained will completely change our lives.”

  — Senator David Boren (D - Oklahoma)

  “The only thing colliding in the land under Texas will be taxpayer dollars.”

  — Congressman Dennis Eckart (D - Ohio)

  February 15, 1993

  “(There is) no reason why we have to find the Higgs boson by the turn of the century.”

  — Dr. John H Gibbons, Clinton’s Presidential Science and Technology

  Advisor, justifying Clinton’s stretchout and cost boost of the SSC

  project.

  CHAPTER 7.1

  Splashdown

  ROGER fell into darkness, embracing his plastic-wrapped backpack as he fell. As his back hit the water, there was a tremendous splash beside him. Some of the concrete floor must have come along with them, he thought. A great wave of water washed over him, thrusting him sideways, sucking him deep.

  The Gulf water felt bathtub-warm and tasted salty. His head and back hit the sandy bottom hard, but he was able to right himself and push upward toward the surface. When his head broke the water’s surface, he was pleased to find that his plastic-wrapped pack had enough buoyancy to support him. He coughed, then shouted hoarsely for George. There was no answer.

  Roger looked around. Moonlight sparkled on the water and lights of the shoreline were visible in the distance. He attempted to stand, extended his feet downward, but the water was too deep, and his head went under. Sneezing water, he removed his water-heavy shoes and socks, shoved the socks in his jeans pockets, tied the shoe laces together, and hung his shoes around his neck. Then, embracing the pack, he began to kick in the direction of the shore. After about ten minutes of kicking, he tested the depth again. This time he could stand on the bottom. He dragged his legs through the water toward the shore. A large wave broke over him, knocking him down, but he righted himself and continued.

  Finally Roger staggered out of the water and sat down on an inverted plastic bucket that someone had left on the beach. A full moon was overhead, and the moonlight gleamed across the water. He undressed, wrung the salty water from his clothes, and put them back on. He was a bit cold, but it was not too bad because the air was fairly warm. “George,” he called again. “Where are you?”

  To his left he heard a call in the distance. In the moonlight he could see George walking toward him down the beach.

  “Well, I see you managed to stay afloat, Roger,” George said. “I’m glad the Makers didn’t place their Bridgehead any higher. I hit the water pretty hard.”

  “As did I,” said Roger, removing the plastic cover and shouldering his backpack. “Time travel, so far, has been an unpleasant soggy business.”

  The stilt house they had rented seventeen years in the future was not there. In its place was only a weedy lot bearing a “Beach Front Property for Sale” sign. Roger found a yellowed newspaper in the tall weeds. He was able to read it fairly well in the bright moonlight. The masthead said “Houston Chronicle, Friday, January 30, 1987.” He laughed aloud, for a small article in the lower left hand corner of the front page bore the headline “Reagan Announces Super Collider.” He could barely make out the text. It said the machine would cost $
4.4 billion and be completed in 1996. He showed it to George.

  “Ah, yes,” said George, “it all comes back. Reagan’s Department of Energy got the project started with an amazingly low cost estimate that left out inflation and the cost of the detectors. The damn thing actually cost $8 billion and wasn’t up and running until 2003. Congress was rather unpleasant about that.”

  They walked eastward on the beach toward the lights of Galveston and came to an impromptu picnic table made from a battered sheet of sun-bleached plywood.

  “Wait a bit,” said Roger. “I think we should stop here and do an inventory. I suggest we put all our possessions on this table and see what we’ve brought with us.”

  It was an interesting collection. There were two Bridge detectors, useless as detectors but fully functional as cutting lasers. George’s Swiss Army knife with the toothpick missing showed dark red in the moonlight. Two key rings held keys that would not fit any existing locks, and George’s had a car door lock remote control that would not be manufactured for another 10 years. The eight credit cards and chip cards all had issue and expiration dates in the 21st century. There was $423 in US currency, all signed by a Treasury Secretary who had not yet been appointed and bearing the series mark of a printing in the year 2000. There were various coins, most with dates of issue later than 1987. Roger’s British Passport had been issued in 2002 and his INS green card was dated 2004. George’s Washington State Driver’s License with picture ID had an issue date of 2003 and an expiration date of 2008, sealed with a hologram. There were two personal cell-phones that no longer functioned and two digital databank wrist watches that, on close inspection, were clear anachronisms. Roger’s backpack contained the most glaring anachronism of all, his personal 500 MHz lapstation containing several terabytes of stored programs and holo-ROM books and data which included the level one download from the Makers.
