Part 7/9:

Traveling beyond our solar system brings extraordinary challenges. Proposals like generational ships demand intact societies that can manage all necessities for survival, including food, energy, and life support. The endeavor is daunting, and humanity must also contemplate radical solutions like uploading consciousness into machines to traverse the cosmos efficiently.

By achieving galactic expansion, humanity could weather cosmic calamities such as galaxy collisions—an event forecasted to occur when the Andromeda galaxy merges with the Milky Way. Such instability could propel entire solar systems into uncharted territories, lengthening the odds against humanity's survival.
