The projector was gone. That was the first thing Maya noticed when they came back in after lunch. The great black machine that had thrown stars on the ceiling for forty years had been wheeled out on a dolly, and now the middle of the dome was just an empty circle of floor.
Their aunt Priya was somewhere in the back, arguing on the phone about a truck. She had given them one job. Walk the seats, check under each one, box up anything left behind.
Soren found a mitten, a single earring, and a library card from 1998. Maya found a quarter and a note that said MEET ME UNDER ORION which had clearly never been delivered.
Then the work lights went out.
Not a power cut. A timer, probably, set to save money now that the shows were done. The dome went black, black the way only a room with no windows can go.
"Don't move," Soren said. "There's a step somewhere."
But Maya was already looking up. Above them, faint and green and cold, the stars had come back.
Not the projector's stars. Those were gone. These were painted on. Thousands of little dots across the whole curve of the dome, glowing like they had been waiting all day for the lights to leave.
"They kept some," she said. "They painted stars up there and just kept them."
Soren stopped worrying about the step. He tipped his head back until his neck ached.
"They weren't glowing an hour ago," he said. "When the lights were on, the ceiling was just gray."
"They were glowing. We couldn't tell."
"No." He said it carefully, the way he said things when he was building toward something. "I looked up when we came in. Gray. Nothing. So they turned on when the lights turned off."
Maya sat down in the nearest seat so she could stare straight up. "Things don't turn on when you turn other things off. That's backwards."
They watched. The green dots hung there, steady, patient. One brighter patch near the edge of the dome, where the painter must have laid the stuff on thick, glowed almost like a real planet.
Soren pulled out his notebook and held it up toward the brightest patch. He couldn't read his own writing. He put the notebook away.
"Feel the ceiling when the lights come back," Maya said suddenly. "That's what I want to do. I want to know if it's warm."
"You think it's heat?"
"I think it ate the light." She said it fast, before she was sure. Then she went after it. "All day the work lights were pouring down. The paint was drinking it. Then the lights went off and it's giving it back. Slow. Like a sponge you squeeze."
Soren turned this over. "A sponge gives the water back the second you squeeze. This is giving it back for, what, we've been sitting here five minutes and it hasn't dimmed."
"So it's a slow sponge."
"So it's a slow sponge," he agreed. He liked that. He wanted to test it. "Okay. If it's holding light it drank, then a spot that got more light should be brighter now. And a spot that got less should be dimmer. Look at the door."
Above the exit, where a strip of hallway light had been leaking in all afternoon, the stars were bright and hard. In the far corner, behind where the projector had blocked the ceiling, the stars were barely there, a whisper of green, almost gone.
"The projector shaded them," Maya said. "For forty years it stood right there and those stars never got the shows. They're the dim ones."
Neither of them said anything for a while. The dome breathed cold around them. Maya thought about the paint holding this afternoon inside itself right now, this exact afternoon, the lunch they ate and the mitten and the note under Orion, all of it stored up there as light waiting to leak out in the dark.
"It's still going," Soren said. His voice had gone quiet. "That's the part. It's still going."
He was doing the arithmetic out loud, the way he did. "The light hit it hours ago. Some of it hit it this morning before we even got here. And it's coming out now. So the light that's landing on my eyes right now is old. It left the lamp this morning and the ceiling caught it and held it and it's only reaching me now."
"Like the real ones," Maya said.
Soren looked at her.
"The real stars," she said. "The light's old. It left forever ago and it's only getting here now. Aunt Priya said that in the last show. The light you see already happened. We're always looking at the past."
The painted dots glowed above them, green and slow, giving back a morning that was already over.
"They built a ceiling that does the same thing the sky does," Soren said. "On purpose or by accident, they built a sky that shows you the past."
"Every ceiling does it. Every wall." Maya was leaning forward now. "Everything's holding some light and letting it out slow, just too slow or too fast for us to catch. We only see it here because somebody made paint that's exactly slow enough for a kid to notice."
Soren wanted to argue and found he couldn't. He wanted it to be true too much.
Somewhere in the back, Aunt Priya finished her phone call. Her footsteps came toward the door, and her hand found the switch, and she said, "Sorry, sorry, the timer, hang on."
"Don't," they both said at once.
Her hand stopped on the switch. In the dark she looked up, following their faces, and they heard her breathe in.
"Oh," she said. "They left the stars."
Maya stood up on the seat and reached toward the brightest patch, the planet that wasn't a planet, and held her open hand flat under it so the old green light pooled in her palm and spilled between her fingers and kept coming.
