It was a computer’s paradise. No world could have been more hostile to life, or more hospitable to intelligence.

And intelligence was there, dwelling in a planet-wide incrustation of crystals and microscopic metal threads. The feeble light of the two contending galaxies– briefly doubled every few centuries by the flicker of the supernova– fell upon a static landscape of sculptured geometrical forms. Nothing moved, for there was no need of movement in a world where thoughts flashed from one hemisphere to the other at the speed of light. Where only information was important, it was a waste of precious energy to transfer bulk matter.
