Warp Drive Soliton Inertia

Hello All, In this post I log some thoughts on another proposed challenge to superluminal warp drives: acceleration of the soliton past the speed of light. In their paper published earlier this year, Bobrick and Martire ( Introducing Physical Warp Drives ) state on page 17 of their pre-print that one cannot accelerate a subluminal warp drive to superluminal speeds for similar reasons as why one cannot accelerate masses moving through space-time to superluminal speeds: Warp drives can move superluminally only in the same sense as any ordinary inertial mass, test mass, or any other object. Namely, there is no known way of accelerating regular material beyond the speed of light. However, one may postulate a test particle which moves faster than light in relativity, in which case it may continue moving inertially. In the same way, a s warp drives are shells of material, there is no known way of accelerating a warp drive beyond the speed of light. However, one may also postulate the warp
