marsissippi··on Passing stars changed the orbits of planets in the solar system
Lisa Randall's book "Dark Matter and the Dinosaurs" has that vibe (not about passing stars, but about the solar system passing through an area of the galaxy thick with dark matter - but the imagined impact is the same).

Great short article. Takeaway: because of ancient star flybys

"the uncertainties of Earth’s past orbit make it difficult to be confident more than 50 million years. And that has a significant impact on paleoclimate studies."

Interesting Pull quote:

GPT-4 needed about 50 gigawatt-hours of energy to train. Using our scaling factor of 30x, we expect GPT-5 to need 1,500, GPT-6 to need 45,000, and GPT-7 to need 1.3 million.
