244 — 10.16. 100.

No sender. No subject. Just those three numbers, separated by an odd, deliberate rhythm.

She looked at the numbers one last time. They weren't a message anymore. They were a key. 10.16. 100. 244

"Coordinates," she said. "And I think we just turned the lock."

She opened a starchart. 100 hours of arc. 244 degrees. A line of sight pointing not outward, but back toward Earth. Toward the buried salt flat beneath them. Toward something that had been asleep for millennia—until 10:16 PM. No sender

"Why? What is it?"

The dots weren't decimal points. They were separators. Like coordinates. Or a countdown. : Are you looking for a conversion between

The number 10 is the decimal representation of the binary number $1010_2$. The square of this binary value ($1010_2 \times 1010_2$) is $1100100_2$. When this binary result is converted back to decimal, it equals 100. Thus, the transition from 10 to 100 is not a random leap, but the result of squaring the value within the binary system before expressing it in decimal.

"Check the Array’s own logs for 10:16 UTC," she said. Leo’s face went pale. "That’s… now. The message arrived the same second we received it. No propagation delay. It didn’t come from space, Mira. It came through the Array—as if something used our own dish to talk to us."

Dr. Mira Vasquez had seen plenty of strange data in her fifteen years at the Array—a sprawling deep-space listening post buried in the Atacama Desert. But this was different. The numbers weren't random noise. They were precise. Encoded.
