Alright, given everything we've learned in LM, if Roshar and Scadrial we're to fight who would win?
For the purposes of this thread we will be assuming that each side only gets their native powers and people. So Scadrial doesn't get the Ghostbloods, Roshar doesn't get Nightblood.
Shards and Dawnshards will not be considered.
I find it more likely that he would use steel against something inside the ship, such as holding one of the pistons in the engine shut. That wouldn't crush him between those forces.
Yes we do, use the SR to bypass space, as the SR is all places in one. Hence there is no distance between places, as can be seen by Oathgates being FTL. So where you are going doesn't matter. Aon Tia can get you anywhere, Oathgates can get you anywhere, Bondsmith/Elsecaller portals can get you anywhere.
