Part 6/9:
To extend survival, colonizing planets and moons is critical. But this process entails overcoming immense technological hurdles. One proposed method involves generational ships, self-sustaining societies traveling to distant stars. Alternatively, solving issues around biological immortality and cryogenics would allow for long-term space travel.
Moving beyond just expansion, humanity may ultimately need to establish colonies throughout the galaxy. Space-faring civilizations would be incredibly resilient and could thrive for hundreds of trillions of years, provided they manage resources effectively.
