In the begining of the first season of Enterprice there was a lot of talk about new warp 5 engine
so my question is whats the difference between warp 5 engine and engines that came before (and i am not talking about warp 5 engine faster i am talking about the reason its faster)
my original theory is that warp 5 engine isfirst M/AM reactor
and that everything that came before is fusian reactors
And the reason i want to confirm my theory because i am just sturted making J class freighter deck plans and i dont know what to put in engenearing
