**Don't forget the sun moves.** A galactic year is 225-250 million years (the time it takes for the sun to orbit the center of the Milky Way). Our sun is 18 galactic years old, and will only live until 40. For context, the aeon of time between the dinosaurs and ChatGPT is .28 galactic years, effectively, a single galactic season. Worth noting though, it took 3 billion years for multi-cellular life to emerge. So if life on Earth gets completely nuked, it could take 12 galactic years to re-emerge from scratch. We’ll be 30. Interesting to think—we have 3 shots to escape space-time.
