Or will it allow them to fix the future?They entered the great chamber. At the far end, technicians hovered around an immense illuminated board, following a complex pattern of lights that shifted rapidly, flashing through seemingly endless combinations. At long tables machines whirred -- computers, human-operated and robot. Wall-charts covered every inch of vertical space. Hasten gazed around him in amazement.Wood laughed. "Come over here and I'll really show you something. You recognize this, don't you?"

The future." "You're dredging the future? But you can't! It's forbidden by law; you know that!"
