Part 3/12:
When contemplating intergalactic travel, science fiction often presents the idea of faster-than-light (FTL) travel, allowing ships to traverse vast distances in mere moments. In reality, however, we stand constrained by the laws of physics as we understand them, often assuming space travel would occur at a fraction of light speed. Massive vessels would be required, capable of sustaining human life for centuries or preserving individuals in stasis across the voyage.
