Detta behandlas specifikt i filmens officiella novellering . Märket planerade att landa på den återstående planet (Edmunds värld) med Coop och mellan dem skulle de inkubera tioisiga embryon med hjälp av en artificiell livmoder. Dessa barn skulle då bilda ryggraden i en ny mänsklig befolkning med en blandning av surrogat och normal graviditet.
Slutligen var den enda skillnaden mellan vad som var planerat från början och slutresultatet att istället för att hanteras av fyra vuxna, började de bomben med en enda vuxen:
This is one way. Plan B — a population bomb. Almost five thousand fertilized eggs, preserved in containers weighing in at under nine hundred kilos.” Five thousand children, he thought. Five thousand, in this little vault, waiting to be brought into the world.
“How could you raise them?” Cooper asked.
“With equipment on board, we incubate the first ten,” Brand replied, as if she was talking about planting corn. “After that, with surrogacy, the growth becomes exponential. Within thirty years, we might have a colony of hundreds. The real difficulty of colonization is genetic diversity.” She pointed to the glass vials enclosed by the device. “This takes care of that.”

She had been trying to stay occupied with the particulars of her duties—primarily making certain that they could still implement plan B. The population bomb had been roughed up enough that she’d needed to overhaul the cryonics, which she had managed to accomplish with a little help from Case. It was a makeshift fix that required cannibalizing Romilly’s cryo-bed, but then again, he wasn’t going to need it. Once they made planetfall, she could use some parts of the Endurance they still needed to rig a more reliable system. They couldn’t thaw all of the embryos at once—the bomb would need to continue working for decades, at least.
She wondered how many children she and Cooper would be able to manage, now that it was just the two of them. Five? Ten?
At least he had some experience along those lines.
You want a big family, Coop? It was going to be an odd conversation to have. Probably a painful one, too—at least for him.
