less so in nutrek, old trek usually has some techno-babble included. i wonder if they think the viewers will get bored to death from a pseudo-explanation of how warp works, eventhough they sorta explained it over the franchise as (contracting and expanding space using a subspace field).

transwarp, vortex, slipstream kinda sidesteps the speed of light in our own universe, by interdimensional travel, hence why its faster than warp.
