As time continued moving forward, the remaining civilizations understood that their role had become very important.
The universe was now old and quiet, and fewer societies still existed.
Because of this, the task of preserving knowledge became one of their most important responsibilities.
Large archives were carefully maintained inside protected habitats.
These archives stored records of science, history, technology, and culture.
They also contained information about thousands of civilizations that had once existed across the universe.
Some records described early planets filled with life.
Others explained how intelligent species had learned to build cities, explore space, and understand the laws of physics.
Every generation continued adding new observations to these archives.
Even small discoveries were recorded.
A new measurement of cosmic radiation.
A better understanding of particle decay.
A new method for preserving energy.
