Q: How was Sentinel Prime supposed to save humans from gravitational disturbance caused by Cybertron? In Transformers: Dark of the Moon movie, Sentinel Prime was going to use cheap human resources (and other natural resources) to re-build Cybertron. So, humans were important to him. Killing humans wasn't his intention. Right?
If Cybertron was successfully materialized near Earth, there'd be a big gravitational disturbance in Sol System which would alter trajectory of Earth (Cybertron was much bigger than Earth. And, as it was metal world, it was denser, too. So, its mass should also be much greater than Earth). Such thing was going to kill all humans, for sure (due to instant weather changes, dynamic weather, tremendous inertial forces, Super tidal waves etc).
How was Sentinel Prime going to save humans from this crisis? I don't think Sentinel Prime failed to think about this (he was Einstein of Cybertron). Is there a technology mentioned in IDW comics, novels which could prevent this?
Or, is it a plot hole?

A: It's a problem noted in the mid-80s cartoon; Dark of the Moon is a combination of two stories from that show.  In the relevant cliffhanger, Optimus Prime says 

I have saved Cybertron -- only to destroy the Earth.

In the movie, Cybertron does not complete the transition to Earth-space.  So the devastation of Earth only just starts, and we never see what Sentinel Prime's plan was for using the Humans and Earth's resources before Earth was destroyed.
(My opinion:  Sentinel didn't think it through.)
