They arrived back at the lab at one. As they looked at the terminal, the fluctuation was just getting started. The flat line turned into a wave, the distance between one peak and the next inconstant. The line’s color became red, like a snake awakening after hibernation, wriggling as its skin refilled with blood.

“It must be a malfunction in COBE!” Sha stared at the waveform, terrified.

“It’s not a malfunction.” Wang’s tone was exceedingly calm. He had learned to control himself when faced with such sights.

“We’ll know soon enough,” Sha said. He went to the other two terminals and typed rapidly to bring up the data gathered by the other two satellites, WMAP and Planck.

Now three waveforms moved in sync across the three terminals, exactly alike.

Sha took out a notebook computer and rushed to turn it on. He plugged in a network cable and picked up the phone. Wang could tell from the one-sided conversation that he was trying to get in touch with the Ürümqi radio astronomy observatory. He didn’t explain to Wang what he was doing, his eyes locked onto the browser window on the notebook. Wang could hear his rapid breathing.

A few minutes later, a red waveform appeared in the browser window, moving in step with the other three.

The three satellites and the ground-based observatory confirmed one fact: The universe was flickering.

“Can you print out the waveform?” Wang asked.

Sha wiped away the cold sweat on his forehead and nodded. He moved his mouse and clicked “Print.” Wang grabbed the first page as soon as it came out of the laser printer, and, with a pencil, began to match the distance between the peaks with the Morse code chart he took out of his pocket.

short-long-long-long-long, short-long-long-long-long, long-long-long-long-long, long-long-long-short-short, long-long-long-short-short-short, short-short-long-long-long, short-long-long-long-long, long-long-long-short-short-short, short-short-short-long-long, long-long-short-short-short.

That’s 1108:21:37, Wang thought.

short-long-long-long-long, short-long-long-long-long, long-long-long-long-long, long-long-long-short-short, long-long-long-short-short-short, short-short-long-long-long, short-long-long-long-long, long-long-long-short-short-short, short-short-short-long-long, long-short-short-short-short—that’s 1108:21:36.

The countdown continued at the scale of the universe. Ninety-two hours had already elapsed, and only 1,108 hours remained.

Sha paced back and forth anxiously, pausing from time to time to look at the sequence of numbers Wang was writing down. “Can’t you tell me what’s going on?” he shouted.

“I can’t possibly explain this to you, Dr. Sha. Trust me.” Wang pushed away the pile of papers filled with waveforms. As he stared at the sequence of numbers, he said, “Maybe the three satellites and the observatory are all malfunctioning.”

“You know that’s impossible!”

“What if it’s sabotage?”

“Also impossible! To simultaneously alter the data from three satellites and an observatory on Earth? You’re talking about a supernatural saboteur.”

Wang nodded. Compared to the idea of the universe flickering, he would prefer a supernatural saboteur. But Sha then deprived him of this last glimmer of hope. “It’s easy to confirm this. If the cosmic microwave background is fluctuating this much, we should be able to see it with our own eyes.”

“What are you talking about? The wavelength of the cosmic microwave background is seven centimeters. That’s five orders of magnitude longer than the wavelength of visible light. How can we possibly see it?”

“Using 3K glasses.”

“Three-K glasses?”

“It’s a sort of science toy we made for the Capital Planetarium. With our current level of technology, we could take the six-meter horn antenna used by Penzias and Wilson almost half a century ago to discover the cosmic microwave background and miniaturize it to the size of a pair of glasses. Then we added a converter in the glasses to compress the detected radiation by five orders of magnitude so that seven-centimeter waves are turned into visible red light. This way, visitors can put on the glasses at night and observe the cosmic microwave background on their own. And now, we can use it to see the universe flicker.”

“Where can I find these glasses?”

“At the Capital Planetarium. We made more than twenty pairs.”

“I must get my hands on a pair before five.”
