Before Elvi could ask what had made a copy and what it had made a copy of, he’d floated over to the dining table in the middle of her cabin and slapped his terminal down on it. The electromagnetics in the table kept the terminal from floating away, but the impact sent Fayez tumbling gently toward the wall. He was an Earther, born and raised, and no matter how much time he spent in space, he never seemed to lose that instinctive expectation of gravity. As he drifted away, he yelled at the table, “Show her! Show her… the thing! Display last file, volumetric display.”
A holographic map of what looked like a human brain appeared, floating above the table. The brain sparked with flashing synaptic paths, probably an fMRI or fNIRS scan. Elvi had seen this particular brain often enough to know it belonged to the catalyst. That it had been a woman, once upon a time. Fayez hit the bulkhead and pushed off with one foot, rejoining her at the table.
“A lot of activity,” Elvi said. “But taking her out of her pen might be causing her stress, or physical discomfort. Nothing here is all that unusual.”
“That’s just her being her,” Fayez said, shaking his head and tapping away at his terminal. “Look at this.”
A second image appeared. It took Elvi a moment to recognize that it was a copy of the catalyst’s brain activity, but without the physical structure of the brain.
“I don’t understand. What’s that second image from?”
“That,” Fayez said with a grin, “is coming from the object.”
“What, the whole thing is mirroring her brain activity?”
“No, it’s very localized,” Fayez said, and tinkered with the controls. The second image zoomed out for a long time until the entire object was in view. A tiny white dot appeared. “That dot is not to scale, of course. It’d be the size of Greenland at this distance. But that’s the approximate location of the image.”
He tapped some more, and the image was replaced with long strings of sensor data. “Jen started picking up some EM fluctuation in the surface of the object. I mean, in context it’s tiny, but the object is totally inert, and the sensors on this boat are as sensitive as a galactic tyrant’s money can buy.”
“Okay,” Elvi said. “What does she think we’re looking at?”
“At first it just looked like some photons bouncing around, until Jen put together this map. No one knew what we were looking at until Travon said, ‘Hey, that looks like an fMRI.’ I pulled up the catalyst’s monitor, and boom, there we were.”
Elvi didn’t mind space, but the one thing it lacked that she needed right then was the ability to collapse into a chair. She felt a rush of adrenaline that made her hands tingle and her legs go numb.
“So they’re echoing each other?”
“Like looking in a mirror.”
“Oh,” she said. Then, “Okay. That’s huge.”
“Oh, it gets huger,” Fayez said. “All across the object we’re now seeing radiation hotspots”—he zoomed in on one, and a new rush of numerical data splashed across the image—“like this.”
He was looking at her expectantly. Waiting for her to make the connection. She didn’t think she was all that tired, but whatever flash of insight he was looking for just wasn’t there.
“I give up.”
“It took us a minute too,” Fayez said. He pulled up a third image. Elvi recognized a ring gate. “This is the same kind of radiation that sprays out of the gate during a transit.”
Almost before the numbers hit her screen Elvi had it. “That correlated to the catalyst.”
“Yes. Catalyst brain, green diamond-thing copy, and weird distributed gate-like radiation. Three things, all with the same pattern,” Fayez said.
Elvi pulled the image of the huge green diamond back until she could see the whole thing at once. It seemed to flicker with tiny stars of light appearing and disappearing where the computer marked the radiation spikes for her.
“This thing is filled with… gates? Like, in the physical structure of the object itself?”
“We have a theory,” Fayez said. He was grinning like he had the first time she agreed to sleep with him. He was a goofball, but she liked what made him happy: knowing things, and her.
“It’s too early for theories,” she said.
“I know, but we have one anyway. And by we, I mean Travon first, but we’re all on board. This thing comes in contact with a protomolecule-infected mind, it makes a copy of that mind, then these gate signatures start showing up all over the object. Travon starts talking about how secure data storage works. You take the physical imprint that’s the encoded data and you scatter it. You put it in a bunch of discrete storage locations with tags and code built in so that if any portion of the storage system is lost, the rest of it knows how to rebuild the lost portion from the scattered fragments.”
Elvi, who was a lot more computer literate than Fayez, started, “That’s not exactly—”
“So then Jen says, ‘A diamond is a super-dense and incredibly regularly structured mass of carbon atoms. If you had a way to shift things around without damaging the overall structure, it’d make a great data storage material.’”
Elvi paused, her mind ticking through the implications.
