"Acceleration? A change in direction?" The Astronomy Department Minister froze. "That's impossible! Given Star Three's current position and rotation, it's impossible to accelerate Star Two!"
"The new trajectory has been calculated! If it accelerates and changes direction this time, there will be an angular deviation of -0.11727 from our original projected trajectory. At that point, Star Two should pass within 40 million kilometers of our fleet. That distance should be harmless."
"Why would such a drastic orbital shift advance the timeline by a full two days?" the Astronomy Department Minister said. "That's simply impossible! Have you calculated the result?"
"N-No..." An astronomer shook his head blankly.
"Did you factor in Yago-Dur's gravity?"
"We did! Yago-Dur's gravity is nowhere near enough to make a star change direction!"
"Minister! We've figured it out! The thing causing Star Two to accelerate and change direction is Yago-Dur itself!!" Another astronomer displayed a screen full of calculations.
"That's impossible!!" The Astronomy Department Minister lunged over, practically hugging the screen as he stared at the results.
"Gravitational waves! It's gravitational waves!" the astronomer beside him said. "Under the mutual influence of Star Two and Star Three, a large number of gravitational-wave traps formed around them! Over the past seven days, Yago-Dur's rotation resonated with the frequency of the largest gravitational-wave trap! During this process, that gravitational wave became exceptionally powerful and also resonated with the other gravitational waves! It became the fifth source of gravity here!"
"That gravitational wave was the source of the interference disrupting our communications earlier!" another astronomer said, suddenly enlightened. "No wonder the Communications Department said there was nothing at the source of the interference! Their radar equipment can't detect gravitational waves!"
"So it was the combined effect of that gravitational wave and Yago-Dur that accelerated and redirected Star Two?" the Astronomy
