A ship so massive it becomes a world.
Thousands of people. Hundreds of years. Zero resupply.
The people who launch it will never arrive.
But could such a vessel actually keep humanity alive across the void between stars?
In this haunting space documentary, we explore the generation ship - and confront the terrifying reality of what it would take to cross 25 trillion miles of empty space.
In this deep space documentary, we go deep:
→ Why even our fastest probes would take 75,000 years to reach the nearest star
→ The engineering nightmare of keeping thousands alive for centuries without resupply
→ How closed-loop ecosystems must recycle every molecule of air, water, and waste
→ The psychological collapse that could doom a ship within three generations
→ Why the humans who arrive would be nothing like the ones who left
Some journeys are measured not in distance, but in generations.
And some destinations will only be reached by those who were never meant to see home.
