They were silent for a moment, then Harold said, "They can't. They can't shut
down their collider. We're so close."
"Well, that just may be what they're doing. Unless --"
"Unless what?"
"For the past few months, I've been trying to imagine what it would be like for
me to live in that universe. What if I had gotten my collider, and then, just as
it seems to be working, the beams keep vanishing? What would I do?"
"What you did in this universe. Keep fighting until the bitter end."
"Right. But what if we were the ones losing beams? I would have called you in to
examine the data, and what would you have found?"
It took Harold a few seconds. "The physics of the bridge is the same in either
universe. I could probably have developed this theory in the other universe as
well."
Roy smiled. "Which means?"
Harold's eyes lit up. "Which means that they know about us! So if their collider
is in danger of being shut down, they would try to let us know about it!" He
snatched the paper out of Roy's hands, studied it for a moment, and whistled.
"It's Morse code. See here, where the data begins to get loopy? It's an S.O.S.!"

"So what does the rest of the message say?"
"Give me a minute. It'll be easier if we use the computer to graph the pulse
length versus time..."
It was more like ten minutes until Harold had completely translated the message.
Most of the message confirmed their ideas about the other universe. But it ended
on a very ominous note.
Harold read, "'Shutdown scheduled in few weeks. Must present data. Do you have
any?'" He looked up at Roy, who rubbed his eyes.
"Well, yeah, we do," Roy said, "but how do we share it with them?"
Harold got that twinkle in his eye again.
"You mean, how do we signal them back when we don't have a beam?"
"Yes."
Harold laughed. "Easy. Same way they signaled us, but in reverse. We set up the
detectors to turn on and off very rapidly in Morse code, so when they send a
beam over to us, they get a staggered disappearance instead of the usual 'zing!'
kind. Our communication does depend on their sending us a beam, but we can still
communicate. It's a simple application of Heisenberg's Uncertainty Principle and
Bell's Theorem. We'll just need a SQUID."
A Superconducting Quantum Interference Device. A tiny integrated circuit cell
made with superconductors, about the size of a transistor. Roy nodded. That made
sense. They needed to interfere with the quantum mechanical nature of the beams,
and both ideas Harold had cited involved quantum interactions. Bell's Theorem,
in particular, involved the quantum nature of information transfer. "If you can
figure it out --"
"I can."
"Then let's do it."
