Is an hour in space 7 years on Earth?
The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth
