But the whole universe faced the same fate. Time was quantized; there was no prospect of infinite computation before the Big Crunch, for anyone. If everything that ended was void, the Dive had merely spared them the prolonged false hope of immortality. If every moment stood alone, complete in itself, then nothing could rob them of their happiness.
The truth, of course, lay somewhere in between.
Timon approached her, grinning with delight. “What are you pondering here by yourself?”
She took his hand. “Small networks.”
Cordelia said to Vikram, “Now that you know precisely what phase is, and how it determines probabilities… is there any way we could use the experimental beams to manipulate the probabilities for the geometry ahead of us? Twist back the light cones just enough to keep us skirting the Planck region? Spiral back up around the singularity for a few billion years, until the Big Crunch comes, or the hole evaporates from Hawking radiation?”
Vikram looked stunned for a moment, then he began launching software. Sachio and Tiet came and helped him, searching for computational shortcuts. Gisela looked on, light-headed, hardly daring to hope. 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. “No. It’s not possible.”
Cordelia smiled. “That’s all right. I was just curious.”
