Dr. Mei Lin had spent eleven years of her life training for a moment that lasted fourteen seconds.

"Guidance nominal," the mission commander's voice crackled in her ear. "Dr. Lin, you are go for EV drop."

Mei checked her suit seals for the fourteenth time. Habit. Ritual. The things you did when you were about to step out of an airlock and into the nothing that had been the dream of every human who ever looked up.

"Copy, Commander. EV drop in T-minus sixty seconds."

Mei floated in the airlock, her helmet visor reflecting the instrument panel. On the other side of that door was the Lagrange Point—the invisible sweet spot between Earth and Moon where gravity canceled itself out and you could float forever, if you didn't mind the radiation and the silence and the terrible, crushing knowledge that you were nowhere.

The airlock cycled. The outer door opened.

Mei had seen space a hundred times in simulations, in videos, in the memories of the astronauts who had come before her. But nothing—nothing—prepared her for the actual view. Earth was a blue arc below her, the Moon a cratered bone above. And between them, at the exact point where Earth's pull and the Moon's pull balanced, was the Observatory.

It was a necklace of mirrored panels, a halo of gold foil and carbon fiber, floating in the dark. And inside it, a signal.

"Mei, do you copy?" It was Dr. Okonkwo, the mission's xenolinguist. She sounded like she was crying. "Mei, the signal—it's not random. We've been analyzing it for six hours. It's mathematics, Mei. It's... it's a greeting."

Mei propelled herself toward the Observatory's airlock. Her heart was hammering—not from fear, but from the pure, dizzying adrenaline of a scientist who had just been handed proof that the universe was not silent.

She cycled through the airlock, drifted into the main lab, and saw the data on the screens.

The signal was a sequence of prime numbers. 2. 3. 5. 7. 11. 13. 17. 19. 23. 29. 31. A universal language—the one thing that any intelligence, anywhere in the universe, would recognize.

"It's coming from where?" Mei asked.

"Outside the solar system," Okonkwo said. "Four thousand light-years. The signal left before humans had fire, Mei. And it's still coming. They're still sending it."

Mei sat down hard. Four thousand years. The signal had been traveling for four thousand years. Somewhere out there, a civilization had been broadcasting a greeting for four thousand years, hoping that someone—anyone—would answer.

"Okay," Mei said. "Okay. We answer. What do we send?"

They spent the next month building the response. It was the hardest thing Mei had ever done, and also the most beautiful. She worked with Okonkwo and the mission's composer, a woman named Yuki who had brought a violin onto the mission because someone had argued that music was the only human invention that couldn't be reduced to binary.

They built a message that contained: the first hundred prime numbers (to say we understand), a mathematical description of DNA (to say this is what we are), a recording of a violin playing Bach's Air on the G String (to say this is what we feel), and a simple map of Earth's location relative to fourteen pulsars (to say this is where we are, come find us).

They transmitted it on a Tuesday.

Mei sat in the Observatory's observation deck and watched Earth shrink into a blue dot as the transmission dish turned toward the stars. The signal would take four thousand years to arrive. By then, Mei would be long dead. The International Space Station would be long dead. Maybe the human race would be long dead.

But the message would be out there. A bottle in the cosmic ocean.

That night, Mei couldn't sleep. She floated in the dark, looking out the porthole at the stars. One of those stars—one tiny, unremarkable point of light—was the home of the people who had sent the signal. She would never meet them. She would never know if they received the answer.

But she had answered.

Mei closed her eyes and dreamed of a future—four thousand years from now, when her message arrived and someone, somewhere, saw the prime numbers, understood the DNA, heard the violin, and smiled.

That was enough.
