Why Surviving Interstellar Space Is Worse Than Reaching It

The true nightmare of an interstellar voyage isn't the destination—it's the journey. Even if we solve propulsion, the human body was never designed for a decades-long deep freeze. Prolonged coma risks deadly blood clots and muscle wasting, while freezing remains fatal for human hearts. Unrelenting cosmic radiation triggers cancer, cognitive decline, and genetic damage, impossible to fully shield against. Add psychological collapse from isolation and a generation ship's social fragility, and the space between stars becomes a tomb.
