WIRED take a look at the physics of a key scene in Rogue One, the scene of the Hammerhead Corvette (or should that be covfefe?) ramming into a stricken Imperial Star Destroyer.

Two star destroyers wage a pitched battle against a whole bunch of rebel ships. Several Y-wing starfighters disable one of the star destroyers, and a hammerhead corvette shoves it into the other one. It’s a great move by the rebels, but I’m not here to discuss military tactics. I’m here to talk about physics, and this battle offers a great opportunity for that.

I will break it down into three parts: the collision, the debris trail, and the motion of the star destroyer.

Read on for the breakdown of those three parts.
