You mean they are learning how to make more advanced explodium Nacelles. They started out with ones that just might explode when going max speed and now decades later their design does explode when you use max speed. Their gradual Improvements are clearly visible! Now they just need to make sure the next gen explodes under cruising speed and we are golden.Thing is, Yoyodine does continue to make progress. Learning from one's mistakes is an important skill, after all, so by that measure Yoyodine is learning faster than anyone else!
Please tell me you are joking. PLEASE!!! Why would any one think it is a good idea to have a vital part of the ship just float beside it? That is not only stupid but wastes power and space to keep the tractor Emitters active in order to keep the nacelles on their position.You joke but the Voyager-J's warp nacelles are literally disconnected from the rest of the ship.
No its not! This ship did not need 4 years independence or a Industrial replicator. We could have Instead used the wasted space for two extra science labs. That would have brought us to the Sweet Sweet S+ Science to make the class the best laboratory in space!
