Ok, this looks like the right place for this question: Does a ship's total mass affect Warp drive? Let's say I have a freighter and I load the hull full of stuffed teddy bears and my warp drive's maximum speed to Bajor is Warp 5. Let's say I then pack the hull full of Bajoran granite counter tops. Will I need bigger warp engines to go warp 5 to Bolarus? Will it consume more fuel? Do I only loose acceleration? If mass has no effect, what stops someone from warping a proton mass into a planet? Are Warp engines sizes strictly dependant on ship volume? Is the Warping of space and the forward movement of the ship separate functions? I've gone to several sites looking for this answer, but it appears there is no canon answer, so what I am really looking for is what would make the most sense to you?
