The Almosts
Earth’s gravity is almost strong enough to trap chemical rockets on the surface forever. On a planet only ten percent more massive, hydrocarbons could not achieve orbit.
Distance is almost too far. Epsilon Eridani at 10.5 light years is close enough to be conceivable, yet far enough to demand a 550-year journey and a ship that is mostly fuel.
Interstellar dust is almost too destructive — survivable at 0.02c, but lethal at 0.2c.
Time is almost too long for any civilisation built around human lifespans.
Almost. In every direction, the margin is real but thin.
The Voidbreaker does not make interstellar travel look easy. It makes it look barely possible. Every tonne of shielding, every year of transit, every kilogram of propellant is a direct response to a universe that offers no shortcuts and no encouragement.
The ship is not exempt. The Voidbreaker is almost too long to stay structurally sound across centuries. Almost too thin to feel like a vessel rather than a flying fuel pipe. Carrying almost too much propellant to be practical — and not one kilogram more than the mission requires. Everything is engineered right at the edge of what physics and materials will allow, because any smaller makes the mission impossible and any larger makes it impractical.
Nothing about it is comfortable. Nothing is elegant. It is a ship designed by its constraints.
This is not optimism. It is defiance.

The observation that the Voidbreaker makes interstellar travel look barely possible rather than easy — and that this is exactly the right tone — is the human contributor’s formulation.
