Cosmic History

Poul Anderson, Genesis (New York, 2001).

Some time in our future, it is known that, nine thousand years after that, the Solar System will begin a hundred thousand year long passage through a denser region of the interstellar medium. See here.

The Solar System orbits around galactic center once in nearly two hundred million years. Artificial intelligences protect Earth from:

asteroids;
comets;
cosmic clouds;
lethal radiation emitted by supernovae, gamma ray bursters or neutron star collisions.

When necessary, a shield larger than Earth is constructed from interplanetary matter. Preparing for passage close to another star takes a million years and coping with the consequences takes three million. AI mitigates the effects of climates changes and grinding crustal plates but then changes policy and instead observes life adapting.

Self-evolving consciousness spreads among the evolving stars.

    Yes, but the cost of AIs protecting Earth like this came at a high, perhaps too high cost. The AIs in GENESIS gradually deprived mankind of the power to make binding and decisive decisions. It ended with mankind voluntarily choosing to become extinct.
