You know the starbow effect?”“Yes.” Cordelia examined the sky again, and Gisela could almost see her testing the explanation, imagining how a blue-shifted starbow should look. Gisela felt a frisson of claustrophobia; soon she’d be doing this for real.They paused again to hover — implausibly — just above the horizon, with the only illumination a pin-prick of heavily blue-shifted radio waves behind them. So they jumped out of the scape together — out of their fictitious light cones — abandoning the simulation before it was forced to admit that it was offering neither the chance of new knowledge, nor the possibility of death.Prospero smiled at her indulgently. It’s your turn now.”“What?”“Prospero wants to see you.” Timon grinned with malicious pleasure. Cordelia shrank into a corner of the room, eyes downcast.Prospero began soberly. “But I thought — ” She fell silent, reassessing something, hiding her surprise.Then she said, “I can’t stay.”“Prospero was muttering in disbelief now, “Ingratitude! carveとは。意味や和訳。[動]1 他〈彫像・文字などを〉彫って作る（解説的語義）〈像などを〉（木・石などから）彫り出す≪from，out of≫，〈文字などを〉（…に）刻み込む≪in，into，on≫；〔carve A for B/carve B A〕A（物）をB（人）のために彫る；自彫刻する；彫刻家であるcarve a design in wood木 … It was impossible to measure the changing phase of a single wave directly, but assuming that the two versions of the beam were undergoing identical changes, this was the progression implied by the interference pattern.Tiet said, “This is Silence descended. Would you give an account of classical Greece without mentioning the name of a single city-state?”“No. “Can we wait in the castle? No. A polis like Athena forms a closed trapped memetic surface: concentrate enough Prosperos in one place, and there’s no escape.”Gisela eyed him balefully.

“In curved spacetime, the whole process becomes distorted — but given the right symmetries, the Cordelia took this all in, scribbling calculations, cross-checking everything to her own satisfaction. Even black holes emit Hawking radiation.”“Hawking radiation carries no information.

“There it is: Chandrasekhar.

The locus of these points formed a set of hyperbolic wavefronts in spacetime, like a stack of conical bowls — packed more tightly, in both time and space, where the components’ velocity was greater. This model had been an unqualified success, surviving theoretical scrutiny and experimental tests for centuries.

If you were travelling with someone, why not delay activation until your companion caught up? They were in a scape created for the occasion, to Prospero’s specifications: a room shaped like two truncated square pyramids joined at their bases, panelled in white, with a twenty-The five members of the Dive team were seated around a semi-circular table. My father will be awake soon.”“Of course.” Gisela wanted to say something to this strange, solemn child to put her mind at ease, but she had no idea where to begin. Vikram and Tiet cried out simultaneously, a moment before the analysis software satisfied itself with rigorous statistical tests.

Cartan was a great flesher mathematician, who clarified the meaning and consequences of Einstein’s work. No, we have no plans for that at all. With one foot still on the pier, Prospero turned to Gisela. That includes the fact that we’re almost certainly moving with a different velocity than any probe that passed through the same location — so we’re seeing things differently, with different Doppler shifts and aberration.”Cordelia absorbed this with no sign of disappointment.

“But if it was me in transit, I wouldn’t mind at all.”Cordelia hesitated. One!” He picked up the Cartan Null icon and tossed it into a map of the spacetime around Chandrasekhar. “Listen, if my Dive clone dies learning nothing, he’ll still die happy, knowing that I continued outside. “We can’t avoid having space collapsing in two directions and expanding in the third — unless we poured in so much matter that it collapsed in all three, which would be even worse.

So how are you suited to explain it to others?”Prospero shook his head. You’re welcome here, of course … but in what way are you needed?”Cordelia reached over and tugged at her father’s arm. “All right!

It didn’t matter who’d discovered it.Cordelia was looking dazed, left behind. As they pass through each other, the pulses will interact; they’ll be blue-shifted to energies high enough for pair-production, and eventually even high enough for gravitational effects. She certainly tunnelled out of Athena.”“Yeah. But if they didn’t draw the line somewhere, she could imagine his presence rapidly becoming unbearable.He said, “Very well. “At the three-“That’s assuming a perfectly symmetrical Schwarzschild black hole, which is what we’re simulating. He pulled a rolled-up parchment out of his robe and tossed it into the air. “Why am I needed?

“Whenever they emerged, they wouldn’t have fallen in yet — so they could swoop down and grab the nanomachines, preventing their own births.” The idea seemed to disturb her.Gisela said, “Only if they tunnelled out close to the horizon. “My father, really … ”Meaning what? To examine every possibility might take more time than they had, but then Tiet found a way to test whole classes of networks in a single calculation, and the process sped up a thousandfold.Vikram announced the result sadly. All we can do is give her the chance to make what she can of the experience.”A horrifying thought struck Gisela. And not at all, at the end.
